China to live broadcast longest total solar eclipse worldwide

BEIJING, July 17 (Xinhua) -- Worldwide audience will be able to watch the longest solar eclipse in China in this century through TV, Internet and mobile phones on July 22, said the Chinese Academy of Sciences(CAS) National Astronomical Observatories (NAOC) here Friday.

Four stations for live broadcasting will be set up in Chongqing, Wuhan, Hangzhou and Shanghai cities, where the total eclipse can be observed, said Hao Jinxin, NAOC deputy director.

Six stations will be set up in Beijing, Kunming, Urumqi, Taipei and Hong Kong where partial eclipse can be seen, he said.

Video programs from these stations will be sent through headquarters in Beijing to TV stations, websites and service providers of mobile phones for free, he said.

Broadcasting will last from 7:30 a.m. to 11:30 a.m. on July 22.

The broadcasting project was sponsored by NAOC, Microsoft Research Asia, CAS Computer Network Information Center and Shanghai Astronomical Observatory.

The coming total solar eclipse will be the longest that can be observed in China between 1814 and 2309, according to NAOC.

An area of 250 km wide and 10,000 km long, where people can observe the total eclipse, covers the populous Yangtze River valley including several big cities.

In this area, people can observe four to six minutes of total eclipse, said Cheng Zhou, astronomer with the CAS Purple Mountain Observatory based in Nanjing of eastern Jiangsu Province.

However, the location to observe the longest eclipse on July 22,which will last six minutes and 40 seconds, is off the eastern Chinese coast, he said.

In China, Shengsi Islands on East China Sea will be the location to watch the longest eclipse of six minutes and one second, he added.

NASA says hardware problem blamed on OCO satellite crash

WASHINGTON, July 17 (Xinhua) -- A NASA panel investigating the unsuccessful Feb. 24 launch of the Orbiting Carbon Observatory (OCO) said Friday that the mishap was caused because the Taurus launch vehicle fairing failed to separate upon command.

The fairing is a clamshell structure that encapsulates the satellite as it travels through the atmosphere. The failure to shed the fairing mass prevented the satellite from reaching its planned orbit and resulted in its destruction.

The Mishap Investigation Board led by Rick Obenschain, deputy director at NASA's Goddard Space Flight Center, identified four potential causes that could have resulted in the fairing not separating. The panel also provided recommendations to prevent any future problems associated with the four hardware components that could have caused the OCO accident.

The six-member board began its investigation in early March. They conducted hardware testing, performed and reviewed engineering analysis and simulation data, reviewed telemetry data, collected and secured more than 2,000 documents, and conducted 78 interviews of critical personnel associated with the mission.

The official report of the board contains information restricted by U.S. International Traffic in Arms Regulations and company sensitive proprietary information. As a result, the board has prepared a summary of its report, which provides an overview of publicly releasable findings and recommendations regarding the OCO mission failure.

NASA's OCO satellite to study atmospheric carbon dioxide launched aboard a Taurus XL rocket from Vandenberg Air Force Base in California on Feb. 24, but it failed to reach orbit.

New NASA photos show Apollo leftovers on the moon

WASHINGTON 鈥?New NASA photos of the moon show the leftovers from man's exploration 40 years ago. For the first time, photos from space pinpoint equipment left behind from Apollo landings, and even the well-worn tracks made by astronauts on the moon surface. The images are from the Lunar Reconnaissance Orbiter, which was launched last month and now circles the moon in search of future landing sites.

The photos were released Friday, in time for the 40th anniversary of the first moon landing on July 20, 1969. A picture of the Apollo 11 site shows the Eagle lunar module used by Neil Armstrong and Buzz Aldrin.

"It was really great to see the hardware sitting on the surface, waiting for us to come back," said Arizona State University scientist Mark Robinson, who runs the camera on the orbiter. "You could actually see the descent module sitting on the surface."

But that's only if you know where to look. NASA helps out by putting a giant arrow on each photo. The lunar landers look to be square white blobs; the Eagle is a fuzzy image near a crater.

NASA landed on the moon six times, but the orbital camera so far has only photographed five of the landing sites. Apollo 12 will be done later. That leaves Apollo 11 and Apollo 14 through 17. Apollo 13 never landed on the moon because of an explosion on board the ship on the way to the moon.

The images for Apollo 14 are the best so far. Taken on Wednesday, they show the path made by astronauts Alan Shepard Jr. and Edgar Mitchell as they went back and forth from the lander to the work site.

Robinson said the route was "a high traffic zone, sort of like when you go in an old building and the carpet is worn down." A similar but lighter path could be seen at the Apollo 17 site.

Also at the Apollo 14 site, a close examination shows a trail made by the cart used to carry tools, Robinson said.

The photos varied in quality based on how high up the satellite was and the angle of the sun. For Apollo 11, the spaceship was taking pictures from 70 miles above. For Apollo 14, it was six miles closer.

In the next couple months, as the lunar satellite starts its mission to map the moon for future landing sites for astronauts, it will get much better photos, Robinson said. The mission is a first step in NASA's effort to return humans to the moon by 2020.

Other robotic probes, including those launched by Japan and India, have looked for signs that man was on the moon, but their cameras weren't strong enough, NASA officials said.

The Lunar Reconnaissance Orbiter was launched with a second spacecraft that was designed to crash into the moon in the fall to try to find buried ice. The total cost of the mission is $583 million.

WASHINGTON, July 17 (Xinhua) -- After a nearly two-day pursuit, the U.S. space shuttle Endeavour docked with the International Space Station on Friday, delivering the final pieces of the Japanese Kibo complex and a new flight engineer to join the Expedition 20 crew.

According to NASA TV, Endeavour Commander Mark Polansky guided the shuttle to a docking at 1:47 p.m. EDT (1747 GMT) as the two aircraft flew 220 miles about the northern coast of Australia.

Before closing the final 600 feet to the station, Polansky commanded Endeavour through a "backflip" allowing the station's Expedition 20 Commander Gennady Padalka and Flight Engineer Michael Barratt to take photos that imagery experts will review to assess the health of Endeavour's heat shield.

The shuttle and station crews opened hatches and greeted one another at 3:48 p.m. EDT (1848 GMT), beginning more than a week of joint operations between the two crews.

Endeavour lifts off on Wednesday evening from Kennedy Space Center in Florida after five delays, on a track to the International Space Station (ISS).

Endeavour's 16-day mission will feature five spacewalks and complete construction of the Japan Aerospace Exploration Agency's Kibo laboratory. Astronauts will attach a platform to the outside of the Japanese module that will allow experiments to be exposed to space during the first spacewalks.

CAPE CANAVERAL, Fla. 鈥?Astronauts working inside and out installed a porch for experiments on Japan's enormous space station lab Saturday, accomplishing the major objective despite microphone static that often drowned out the spacewalkers' voices.

Veteran spaceman David Wolf and rookie Timothy Kopra could barely make themselves understood at times because of the loud static emanating from Kopra's helmet microphones.

"Dave, you're unreadable," astronaut Christopher Cassidy called from inside the shuttle-station complex.

Two hours later, it was no better. "It's hard to follow along with this comm," Cassidy said, looking for clarification on what the spacewalkers were doing. The trouble lasted the entire 5 1/2-hour spacewalk, the first of five planned during Endeavour's space station visit.

Mission Control officials said it was a challenge to monitor the 220-mile-high action, especially with so many people in orbit 鈥?a record crowd of 13. But they said the static never threatened safety.

The problem apparently was with the two microphone booms in the cap worn by Kopra under his helmet. The booms were too far from his mouth 鈥?he could not move them once his helmet was on 鈥?and the ventilation flow created all the static. The booms may have been bumped as he was putting on his helmet.

This was Kopra's only spacewalk for the mission, so the airwaves should be much quieter when astronauts step back outside Monday.

"Listening to the static throughout the whole (spacewalk) tends to wear you out more than you would expect," said Kieth Johnson, the lead spacewalk officer in Mission Control. "But I think we made it through."

Despite the nerve-racking racket, the spacewalkers managed to prep the Kibo lab 鈥?Hope in Japanese 鈥?and the new porch for their mechanical hookup. Wolf removed a cover from the lab and tossed it overboard; the white cover drifted away, flipping end over end.

The spacewalkers then moved on to other routine work at the international space station as their colleagues inside used the shuttle and station robot arms, one at a time, to lift the Japanese porch from Endeavour's payload bay and hoist it toward the Kibo lab. The spacewalk was over by the time the porch was finally latched in place.

It marked the completion of Japan's $1 billion lab, so big that it required three shuttle flights to launch everything. The first two sections of the lab flew up last year.

The veranda 鈥?about 16 feet square 鈥?will get its first outdoor experiments in five more days.

Mission Control's congratulations to Wolf and Kopra, as they headed back inside, could hardly be heard because of the static. In the end, the two fell behind and had to skip some chores. They managed to free a platform for spare parts that jammed months ago, using a specially designed tool. But they did not have time to release a similar platform on the opposite side of the outpost.

With Apollo 11 on the minds of many back on Earth, NASA noted that Saturday's spacewalk was the 201st by Americans since those first steps on the moon by Neil Armstrong and Buzz Aldrin 40 years ago this Monday.

Remaining inside the linked shuttle and station were 11 astronauts, a full house. The station population swelled to 13 when Endeavour arrived Friday for a 1 1/2-week stay. Kopra, the station's newest resident, will remain on board for another 1 1/2 months.

Earlier Saturday, Mission Control had both good and bad news for the spacefarers.

The good: Endeavour looks to be in fine shape for re-entry at the end of the month, although a review of shuttle photos and other data continues. A surprisingly large amount of foam insulation came off Endeavour's fuel tank during liftoff, but the shuttle ended up with just 16 minor scuff marks on its belly.

The bad: The astronauts were informed of Walter Cronkite's death. Mission Control relayed statements by Armstrong and NASA's new chief, ex-astronaut Charles Bolden, both of whom noted Cronkite's passion for human space exploration.

Space: Is the final frontier all it used to be?

MOON, Pa. 鈥?On July 22, 1969, barely 48 hours after a human being first stepped onto the moon's surface, a community in Pittsburgh's western suburbs called Moon Township had a parade, as suburban communities do.

Understandably, Moon had achieved some notoriety in the weeks leading up to Apollo 11's lunar landing. And on this day, it named Armstrong, Aldrin and Collins honorary citizens and lowered an "astronaut" from a hovering helicopter into Moon Park.

And why not? This was a time of great joy. The Pittsburgh Press was editorializing about the "Moondust Glowing in America's Eyes." The downtown district's "Moonday" shut down offices and some businesses. The Foodland supermarket announced a sale that promised "out-of-this-world specials" to customers: "We've gone lunatic!"

Moon was also the home of Pittsburgh's airport, where soaring into the sky in a metal bird remained a romantic notion. These were still the days when, as TWA once put it, you could climb aboard "super-skyliners" that were "skyclubs by day, skysleepers by night."

We are 40 years older now, we Americans. And many things have changed.

The final Apollo mission came home before Nixon resigned. Skylab fell to Earth. Challenger disintegrated going up, Columbia coming down. Kennedy's New Frontier ethos 鈥?space as a kinder, gentler Manifest Destiny 鈥?slouched into the "Alien" catchphrase: "In space, no one can hear you scream."

Today, the reasons for Americans to pay attention to the ground, rather than the heavens, can be rattled off like a parody of a Billy Joel song. Terrorists. Global warming. Swine flu. Economic collapse. Nukes in North Korea and mass shootings in the heartland.

In Moon, the old airport is gone; its gleaming replacement opened 16 years ago, one township over. Jets still rumble overhead, but airline ads today skip the romance of the skies and emphasize workaday convenience. "Boundless free snacks," says a Jet Blue billboard on nearby I-279.

Yet Moon still hopes. In the park, adults eat in the Apollo picnic area while kids cluster in the playground around the spaceship seesaws, the rocket climber, the piece of metal twisted whimsically into an abstract lunar lander. "Explore Our Universe," the township says, a slogan it introduced in 2004.

But is that something that Americans still desire? Is space, the final frontier, still the American place to aim for? Or when it comes to exploring the stars, was Yogi Berra right when he said that the future ain't what it used to be?

___

"At the frontier, the bonds of custom are broken, and unrestraint is triumphant." So said Frederick Jackson Turner, the 19th-century historian whose ideas showed Americans how important their frontier experience was to them.

"I wanted to be a spaceman 鈥?that's what I wanted to be. But now that I am a spaceman, nobody cares about me." So sang Harry Nilsson, the musician who in 1972 channeled the changing feelings about space exploration in this country.

Today, somewhere between those two absurdly different ideas, sits America's attitude about space.

Through the 1950s and 1960s, it was the vast, uncharted place where the American imagination dwelled, pushed by the fear that the Soviets would get there first. The Space Age was everywhere: Even when it was threatening, it was enchanting. Even when it was menacing, it beckoned. Even when it was lampooned ("The Jetsons") or sublimated (car tailfins), it only reflected how deeply entrenched in the culture it truly was.

But today space occupies a very different place in the popular culture.

Our visions of it have become darker, more suspicious, more xenophobic. When a space shuttle launches, many Americans don't really notice unless something goes wrong. In a country defined by its obsession with novelty, often the response is predictably American, the thing that makes us great and weak at the same time: Been there, done that.

We have gone from stirring Kennedy oratory about "landing a man on the moon and returning him safely to the earth" to an ad for Alexia Crunchy Snacks that promises its product is 鈥?wait for it 鈥?"a giant leap for snackkind."

We have lapped many of yesterday's visions of tomorrow. "Lost in Space" was set in 1997, "Space: 1999" and "2001: A Space Odyssey" in their own obvious years. So many American futures are now in the past.

We have traded optimism 鈥?even the more horrific sci-fi of the 1950s generally operated on the presumption that America would, should, engage with space 鈥?to the creeping menace manifest in "The X-Files," after which you ended up wishing that anything unearthly would just go away.

Pick up a fresh copy of the rebooted, reconstituted, reconfigured comic-book tales of "Flash Gordon" and "Buck Rogers" and a far more malignant vision of a spacefaring future smacks you upside the head. Even the Superman myth has been retooled, in the TV show "Smallville," to include "meteor freaks" and Kryptonians who seem more at home in a Wes Craven movie than Clark Kent's backyard.

Even in this summer's new "Star Trek" movie, the culture's most optimistic take on space travel, Dr. Leonard "Bones" McCoy's usually cheerful cantankerousness plumbs its deepest reaches yet: "Space," he grouses, "is disease and danger wrapped in darkness and silence."

What happened here?

"The wonder has been tapped out," says Jeff Bigley, who runs a comic-book store north of Pittsburgh called Arkham Gift Shoppe (its slogan is "We have issues").

"It's kind of gotten out of the culture," says Bigley, 38. "It seems like there's no new frontier. We made it to the moon and haven't been back in years. Until they start doing more than just putting down a flag, orbiting the Earth just isn't all that exciting."

In fact, some of the more exciting prospects about space travel are coming from private industry 鈥?the so-called "space tourism" initiatives that entrepreneurs are increasingly putting forward. But publicly funded space travel? These days, Americans seem unsure.

Though Gallup polls in recent years show a generally positive attitude toward NASA, attitudes about space exploration itself are mixed.

In 2006, nearly half of Americans polled said the money spent on the space shuttle program would have been better used elsewhere. And in 2004, shortly after President George W. Bush outlined a program to return the United States to the moon and push on to Mars, 23 percent of Americans said the government should be spending less money on space exploration; 13 percent said it shouldn't be funded at all.

"With space exploration, there's no one championing this next generation," says Alex Shear, a professional collector and curator of Americana and consumer goods, much of it from the post-World War II "Space Age."

"After they went up there, there was something anticlimactic about it," Shear says. "You can't have this all on the back burner. Keep it on the front burner. Keep the heat up. And you'll have something that's quintessentially American that we deserve to celebrate."

As it happens, there is another Pittsburgh suburb 鈥?this one a bit north of the city 鈥?called Mars.

Here, the various sports teams are named the Planets, the Meteors, the Martians, the Invaders. A flying saucer, complete with antenna and looking straight out of a Sputnik-era double feature, sits at the corner of Pittsburgh Street and Grand Avenue, just up the road from the Planet Mart.

Ask Jackie Bushee, 12, who attends Mars Area Middle School, what she makes of America's future in space and you'll get a wise answer that, as with so many Americans when it comes to this topic, mixes optimism with skepticism.

About the Apollo 11 landing she says this: "I had to study it last year in sixth grade for science. And no one really cared." Later, she adds: "Kids my age aren't worried about where we are going. We are worried about where we are right now."

But ask her about going somewhere else 鈥?Mars, say 鈥?and a different story emerges. "I think that would be really cool. The moon just seems so boring and easy to get to. Mars, that's something different."

Something different. How very American: we want to be inspired anew. We hunger for it. And though it hasn't felt urgent in many years, space remains in position to feed that American urge for the next big thing, for pushing outward, for testing ourselves and renewing at the edges.

Doubt it? Visit the Smithsonian's National Air and Space Museum on a Saturday morning 鈥?but only if you like big crowds.

Walk past an actual Apollo landing module and think: How in heaven did we land on the moon in something like this? It looks like a foil-and-tarpaper float built for a homecoming parade.

Marvel at the tiny Mercury Friendship 7 capsule, which carried John Glenn into orbit. And then, if you can get to the front of the circle of people ringing it, stand in front of the actual Apollo 11 command module, Columbia.

Then pause, and listen to the voices around you.

"... actual re-entry capsule ..."

"... Collins stayed in the command module ..."

"... looks like a beehive on the bottom ..."

"... can't believe someone did that ..."

In German and Chinese, Japanese and Hindi and, yes, American English, they marvel still at this conical piece of mottled metal that traveled so far. They pose for pictures, shoot video. As they suck on gift-shop candy Shuttle Pops, they reach up to touch Columbia's plastic casing as if they're touching the stars.

We can say that America's space dreams haven't felt urgent for a long time, and we'd have a point. We can say that Bush's 2004 promise to aim for Mars fell flat, and it did. But to these folks, it is all so real and can be again. The embers can be rekindled.

In a new book called "Rocket Men: The Epic Story of the First Men on the Moon," author Craig Nelson ends with a summons that insists it all still matters, that the urgency is still there and should be harnessed as it once was.

"Shouldn't a nation as rich, as energetic, as brilliant and as ingenious as the United States 鈥?a nation founded by explorers 鈥?always be ready for new frontiers?" he asks.

Sure, we can embed our space nightmares in the latest episode of "Battlestar Galactica" and our dormant space dreams in the continually reimagined landscape of Disney's Tomorrowland. But the fact remains that Americans went into space, landed on the moon and returned safely to Earth. And with that stick-to-itiveness, why not Mars? Why not beyond? Why not anything?

That's the whole point of space travel, after all, when you get right down to it.

Science benefits, defense benefits, even theology benefits. But what it's really all about 鈥?for average, non-spacefaring Americans, at least 鈥?is what it always comes back to: that immigrant drive to push outward to a place where the bonds of custom are broken, unrestraint is triumphant and many things are possible. The notion of the Next Big Thing, magnified a million times beyond any scale that even the biggest thinkers of the American story ever dreamed.

And there to contemplate the infinite, as David Bowman the astronaut did when he uttered his awestruck words in "2001: A Space Odyssey."

"My God," he said. "It's full of stars." It still is, and it waits for us. No matter how long it takes.

Space station toilet down, residents line up for relief

BEIJING, July 20 (Xinhuanet) -- One of two commodes aboard the international space station broke down Sunday, forcing a record 13 astronauts currently on board to share a single Russian toilet and one aboard the shuttle Endeavour, according to media reports Monday.

Mission Control advised the crew to hang an "out of service" sign on the toilet until the toilet can be fixed. The six space station residents had to get in line to use a back-up toilet in the Russian part of the station, and Endeavour's seven astronauts were confined to the shuttle bathroom.

Belgian Frank De Winne and American Michael Barratt were assigned to repair the toilet and they had to wear goggles, gloves and masks. They ripped apart the compartment, working well into the evening. Mission Control finally asked them to stop and resume the effort Monday morning.

Flight director Brian Smith declined to speculate whether overuse caused the toilet trouble.

"We don't yet know the extent of the problem," Smith told reporters. "It may turn out to be of no consequence at all. It could turn out to be significant. It's too early to tell right now."

If repairs fails, Apollo-era urine collection bags are on hand, NASA said.

Future lunar mission: Don't be over the moon

WASHINGTON: The United States will today mark the 40th anniversary of its conquest of the moon, a triumph of scientific endeavour now remembered at a time when US dominance in space is increasingly uncertain.

President Barack Obama kicks off a week of events today when he meets at the White House with the crew of the Apollo 11 mission, who became the first to accomplish the dream of ages and walk on the surface of the moon.

"That's one small step for man, one giant leap for mankind," said astronaut Neil Armstrong as he stepped down from the lunar lander on July 20, 1969, as an estimated 500 million people on Earth crowded around televisions and radios.

Four decades ago, at the height of the Cold War, the US achievement was a huge morale booster to a country mired in the bloody Vietnam war, ushering in a new sense of confidence and challenging concepts of science and religion.

But dreams that one day we might all be able to travel to the stars have been rudely brought down to earth.

Only 12 men, all Americans, have ever walked on the moon, and the last to set foot there were in 1972, at the end of the Apollo missions.

Now ambitious plans to put US astronauts back on the moon by 2020 to establish manned lunar bases for further space exploration to Mars under the Constellation project are increasingly in doubt.

And other nations such as Russia, China and even India and Japan are increasingly honing and expanding their own space programs.

"I think we are at an extremely critical juncture as we celebrate this anniversary because, we at least in the US are in the process of deciding ... what is the future of humans in space," said John Logsdon, an expert in aerospace history at the National Air and Space Museum in Washington.

"And without government funding nothing happens," he said.

The cost of the Constellation project is put at about $150 billion, but estimates for the Ares I launcher to put the project into orbit have skyrocketed from $26 billion in 2006 to $44 billion last year.

The mounting costs prompted Obama, soon after he took office, to order a close examination of the program. A blue-ribbon panel of experts headed by former Lockheed Martin CEO Norman Augustine is due to issue recommendations in late August.

"With a few exceptions, we have the technology or the knowledge that we could go to Mars if we wanted with humans," Augustine said recently. "We could put a telescope on the moon if we wanted," he said.

"The technology is by and large there. It boils down to what can we afford?" he asked.

Currently NASA's budget is too small to pay for Constellation's Orion capsule, a more advanced and spacious version of the Apollo lunar module, as well as the Ares I and Ares V launchers needed to put the craft in orbit.

With a space exploration budget of $6 billion in 2009, Senator Bill Nelson of Florida, a former astronaut, said: "NASA simply can't do the job it's been given."

Several events are planned around the country to mark today's historic anniversary. Celebrations will be held from the Kennedy Space Center at Cape Canaveral, Florida, where the Apollo 11 mission blasted off to mission control at the Johnson Space Center in Houston, Texas and at the Air and Space Museum in the US capital.

To recapture one of mankind's most dramatic moments, NASA last week unveiled restored video footage of key moments from the Apollo 11 mission found after a three-year search through some 45,000 video cassettes in its analog archives.

NASA has also upgraded its Internet website to mark the anniversary, which was largely ignored when the 30th anniversary rolled by in July 1999.

And the record of America's crowning achievement remains visible on the moon in the shape of astronauts' footprint.

"The first footprints on the moon will be there for a million years," reads a posting on a NASA website. "There is no wind to blow them away."

Russia still blue over moon landing 40 years later

When Neil Armstrong stepped onto the surface of the moon, it was a first for the Soviet Union 鈥?the first time the U.S. had beaten the U.S.S.R in the space race. Forty years later, the memory of that loss of primacy still seems to sting the Russian soul. When state TV channel Rossiya reported last week on the restoration of video footage of the Apollo 11 moon landing, the account gave a lot of attention to dubious conspiracy theories that the landing was faked.

"In the United States, more than anywhere else, they are sure of the believability of the steps on the moon," the report said, adding that Armstrong keeps a very low profile. "This also seems strange to many people."

For a dozen years before the July 20, 1969, moon landing, Moscow racked up an extraordinary array of superlatives. It was the first to send a craft into orbit, with the Sputnik satellite in 1957. The first human to go into outer space was Russian Yuri Gagarin in 1961. Moscow sent the woman into space, Valentina Tereshkova in 1963; and Alexei Leonov was the first person to venture outside a spacecraft into the endless cosmos, in 1965.

Russia even got to the moon first when the unmanned Luna 2 crashed in 1959. But the drama of the first human footprint on an extraterrestrial body eclipsed everything the Soviets had worked so hard to achieve.

"Beginning with the first flight with a primitive capsule, and then getting to the moon, it was a great achievement for humanity," Russian astronaut Sergei Krikalev said.

"Of course, we would have liked to see the first man on the moon be Soviet, Russian, but that's life ... Our own achievements were very many," he told Associated Press Television News.

In the 40 years since the Apollo 11 landing, the USSR and Russia, which inherited the Soviet legacy, shot ahead of the United States occasionally only to fall further behind.

The Soviet Union put the first space station into orbit with the Salyut 1 in 1971. However, the first crew couldn't get aboard because of docking problems. Another three-man crew later got aboard, but died when a valve failed on the capsule bringing them back to Earth.

Then there was the Mir -- the first space station fit for long-term habitation. It achieved early glory. But that quickly faded after 1991, when the Soviet collapse choked off funding for the space program and the Mir suffered a series of accidents, including a collision and fires that tuned it into a symbol of danger and decay.

Earthlings scanned the sky nervously on the day in 2001 when the 140-ton craft plunged to its fiery end. Luckily, it landed in the Pacific Ocean.

In recent years, Russia's space program has earned as a workhorse rather than a racehorse 鈥?reliable, cooperative, even stolid.

Its cramped Soyuz manned capsules and unmanned Progress cargo ships had already served as the lifeline to the International Space Station for more than two years when the United States grounded its space shuttles in 2003, after the Columbia disintegrated on re-entry. The Russian space program will once again be the gatekeepers to the orbiting laboratory in 2010, when the shuttle fleet is grounded for good.

That doesn't mean Russia has lost its ambitions for primacy in space.

The U.S. is busy planning to replace the shuttles. But last year, Russia awarded contracts for design of its own next-generation spaceship to replace the Soyuz. The competing efforts could trigger a new space race.

Russian space officials meanwhile still seem to be dreaming about winning the next stage of the space race.

They keep talk in tantalizing terms about mounting a manned mission to Mars, although they say that would take at least another 20 years to get off the ground.

"I think this is fine. It's like sports 鈥?at one stage one person wins, at another it's somebody else," said Krikalev.

Never-before seen photo shows Neil Armstrong's face as he first walks across the moon

BEIJING, July 20 -- An amazing new photograph showing Neil Armstrong's face through his space suit visor has come to light.

The image was shot by the movie camera mounted on the lunar lander famously called 'Eagle', but the frame lasts for only a fleeting moment.

It shows Armstrong's face in clear view as he walks across the lunar surface.

He was the first man to walk on the moon, taking that one giant leap for mankind - yet most of the famous shots are of his fellow astronaut Buzz Aldrin, as it was Armstrong who manned the stills camera.

As America marks the 40th anniversary of the first moon landing today, Armstrong, Aldrin and third Apollo 11 crewmate Michael Collins will meet with President Barack Obama at the White House to be honoured for their pioneering mission.

It is likely that it could be the last ever reunion of the ageing space heroes, who were all born in 1930 and last met up in 2004 for the 35th anniversary.

Should we deliberately move species?

On naked patches of land in western Canada and United States, scientists are planting trees that don't belong there. It's a bold experiment to move trees threatened by global warming into places where they may thrive amid a changing climate.

Take the Western larch with its thick grooved bark and green needles. It grows in the valleys and lower mountain slopes in British Columbia's southern interior. Canadian foresters are testing how its seeds will fare when planted farther north 鈥?just below the Arctic Circle.

Something similar will be tried in the Lower 48. Researchers will uproot moisture-loving Sitka spruce and Western redcedar that grace British Columbia's coastal rainforests and drop their seedlings in the dry ponderosa pine forests of Idaho.

All of this swapping begs the question: Should humans lend nature a helping hand?

With global warming threatening the livelihoods of certain plants and animals, this radical idea once dismissed in scientific circles has moved to the forefront of debate and triggered strong emotions among conservationists.

About 20 to 30 percent of species worldwide face a high risk of becoming extinct possibly by 2100 as global temperatures rise, estimated a 2007 report by the Nobel-winning international climate change panel. The group noted that current conservation practices are "generally poorly prepared to adapt to this level of change."

Deliberating moving a species has long been opposed by some, who believe we should not play God with nature and worry that introducing an exotic species 鈥?intentionally or not 鈥?could upset the natural balance and cause unforeseen ripple effects. It has happened before with dire results. Two decades ago, zebra mussels were accidentally introduced into the Great Lakes and millions are now spent every year removing the pest from water pipes.

Others counter that given the grim realities of a warming planet, it would be irresponsible not to intervene as a conservation strategy. Otherwise, trees may suffer from ravaging disease epidemics while critters unable to head north may find themselves trapped in a declining landscape.

"A tree that we plant today better damn well be adapted to the climate for 80 years, not just the climate today," said Greg O'Neill, a geneticist with the British Columbia Ministry of Forests and Range. "We really have to think long-term."

O'Neill is heading the government-funded experiment that will transform certain North American forests into climate change laboratories. The large-scale, first-of-its-kind test involves purposely planting seeds from more a dozen timber species outside their normal comfort zone to see how well they survive decades from now.

It's more than just a brainy exercise. The findings are expected to guide the British Columbia government on forest management policies. While the experiment deals with moving seeds long distances into unaccustomed climates, O'Neill said any real-life action will not be as drastic.

Outsiders are also keenly watching the experiment as a test case for what is professionally known as "assisted migration."

"We'd all prefer species to move naturally," said Duke conservation biologist Stuart Pimm. But "sometimes you just can't get there from here. Some species are going to be isolated and they're going to get stuck."

The notion of relocating species as a pre-emptive strike against climate change has been largely theoretical. In recent years, some groups have tried assisted migration on a limited basis, most notably the effort by volunteers who last year planted seedlings of the endangered Torreya tree found in Florida to the cooler southern Appalachians.

The Canadian experiment currently under way will cover a broad swath, with tree plantings dotting the Yukon near Alaska to southern Oregon.

Past warmings have forced species to migrate to survive without human help. While some have learned to adapt to new surroundings, other have gone extinct. Faced with the possibility of much more rapid climate change, scientists say, some species may not be able to move fast enough to their new destinations and may need a little power boost to preserve biodiversity.

In North America, some critters have already started their march north. The Edith's checkerspot butterfly, which vanished from its southern range, is now fluttering 75 miles higher in elevation. Red foxes have encroached farther into northern Canada and evicted the arctic foxes.

On the plant side, spruce forests are invading the Arctic tundra and impacting caribou and sheep that live there. In the past century, aspen trees in Colorado have moved into the cold-loving spruce fir forests.

How trees will fare in a warmer world is a concern because they tend to be less flighty than animals. Trees depend on wind and pollinators to spread their seeds. And once a tree is planted, it's harder to move it.

Last year, the British Columbia government took the first steps toward ensuring that trees in the province are adapted to future climates by relaxing its seed rules for timber companies when they replant on logged land. Seeds of most tree species can now be planted up to 1,600 feet higher than their current location.

The government's latest experiment will study how humans can help trees move to more northerly spots where they do not currently grow, but may find themselves existing there years from now. It will not deal with introducing foreign tree species, O'Neill said.

This spring, crews fanned across rugged mountains and began the first dozen plantings on cleared forest land in British Columbia's southern interior and on a private plot near Mount St. Helens in Washington state.

Each test site contains some 3,000 seedlings, on average a foot tall, planted side-by-side on five acres. Fluorescent pin-flags and aluminum stakes dot the corners so that scientists can come back every five years to document their health.

The project will eventually include 48 plots around British Columbia, Washington state, Oregon, Montana and Idaho. It will test the ability of 15 tree species to survive in environments colder and hotter than they're used to.

O'Neill knows that some trees will die and others will go through erratic growth cycles. In fact, he estimates about 50 percent of the plantings may die, but he needs to collect the data to get an idea of how much they can tolerate.

"It will take several extreme climatic events to find out the winners and losers," he said.

Endeavour crew to undertake second spacewalk

Astronauts from the US space shuttle Endeavour were to venture into open space Monday on the mission's second spacewalk aimed at helping complete the International Space Station.

Astronauts Dave Wolf and Tom Marshburn spent part of Sunday preparing special tools, reviewing procedures and beginning their campout in a special decompression chamber in preparation for the walk, which is set to start at 11:28 am (1528 GMT).

The bulk of the Sunday's schedule was taken up with moving equipment from the Endeavour onto the ISS and fixing a malfunctioning toilet system aboard the ISS.

The toilet was likely flooded earlier in the day when its dose pump failed after running for about 15 minutes, NASA officials said.

As a result, about six liters of pre-treated water may have flowed into the pump separator and other areas, flooding the separator.

On Saturday, Tim Kopra and Wolf carried out a five-hour and 32-minute spacewalk to complete construction of the Japanese Kibo laboratory.

"The third and final piece of Japan?s Kibo laboratory was assembled on orbit Saturday, a symphony of robotic and spacewalking performances by the 13-member orchestra aboard the International Space Station complex," NASA said in a statement.

The 1.9-tonne unit known as the Japanese Exposed Facility (JEF) will serve "as a type of porch for experiments that require direct exposure to space," NASA said.

Earlier, on their first full day in space, the Endeavour crew of six Americans and one Canadian tested rendezvous equipment, installed a camera for the orbiter docking system and extended the docking ring that sits on top of the system.

The Endeavour mission aims to help fulfill "Japan's hope for an out-of-this-world space laboratory," as the shuttle delivers state-of-the-art equipment to conduct experiments in the vacuum of space, according to NASA.

The shuttle successfully docked at the space station Friday amid questions about the integrity of the shuttle's heat shield tiles.

However, NASA on Saturday said that a close analysis of pictures of Endeavour's heat shield confirmed the absence of any damage.

During the delicate docking maneuver Friday the two space vehicles traveled at 28,000 kilometers (17,398 miles) per hour as they approached each other, giving Commander Mark Polansky a margin of error of 4.5 centimeters (1.8 inches) to complete the procedure, NASA said.

The entry of Endeavour's crew aboard the ISS brought the number of astronauts inside the orbiting space station to a record 13.

Endeavour crew member Kopra will be staying aboard the ISS, taking over from Japanese engineer Koichi Wakata, who has been in space for 124 days.

The ISS should be completed in 2010, also the target date for the retirement of the US fleet of three space shuttles.

Apollo 11 astronauts look beyond moon, toward Mars

The astronauts who first landed on the moon aren't dwelling on their small lunar steps. Instead, two of them on Sunday urged mankind to take a giant leap to Mars.

In one of their few joint public appearances, the crew of Apollo 11 spoke on the eve of the 40th anniversary of man's first landing on the moon, but didn't get soggy with nostalgia. They instead spoke about the future and the more distant past.

On Monday, the three astronauts will get another chance to make the pitch for a Mars trip, this time to someone with a little more sway: President Barack Obama.

Sunday night, a packed crowd at the Smithsonian Institution's National Air and Space Museum 鈥?7,000 people applied in a lottery for 485 seats 鈥?didn't get the intimate details of the Eagle's landing on the moon with little fuel left, or what the moon looked like, or what it felt like to be there.

They got second man on the moon Buzz Aldrin's pitch for Mars. He said the best way to honor the Apollo astronauts "is to follow in our footsteps; to boldly go again on a new mission of exploration."

First man on the moon Neil Armstrong only discussed Apollo 11 for about 11 seconds. He gave a professorial lecture titled "Goddard, governance and geophysics," looking at the inventions and discoveries that led to his historic "small step for a man" on July 20, 1969

Armstrong said the space race was "the ultimate peaceful competition: USA versus U.S.S.R. It did allow both sides to take the high road with the objectives of science and learning and exploration."

Apollo 11 command module pilot Michael Collins, who circled the moon alone while Armstrong and Aldrin walked on it, said the moon was not interesting, but Mars is.

"Sometimes I think I flew to the wrong place. Mars was always my favorite as a kid and it still is today," Collins said. "I'd like to see Mars become the focus, just as John F. Kennedy focused on the moon."

The man who founded and directed Mission Control Houston, Christopher Kraft Jr., also jumped on the go-somewhere-new, do-something-different bandwagon.

"What we need is new technology; we have not had that since Apollo," Kraft said as part of the lecture at the Smithsonian. "I say to Mr. Obama: Let's get on with it. Let's invest in the future."

As the men of NASA of the 1960s talked about new technology and new goals, the current NASA is still looking back at the moon.

NASA is still marching toward a goal of returning to the moon of Armstrong and Aldrin and this time putting a base there. The current plan is based on building new rockets that the former NASA administrator called "Apollo on steroids," with an alternative 鈥?a derivative of the space shuttle 鈥?floating through the space agency.

Although they didn't directly criticize NASA's current plans, Aldrin and Collins said the moon is old hat. Collins said he is afraid that NASA's exploration plans would be bogged down by a return visit to the moon.

Aldrin presented an elaborate slide detailing how to make a quick visit to the moon a stepping stone to visits to the Martian moon Phobos, Mars itself, and even some asteroids like Apophis that may someday hit Earth. Aldrin said he and Armstrong landed on the moon 66 years after the Wright brothers first flew an airplane. What he would like would be for humanity to land on Mars 66 years after his flight. That would be 2035.

And even though Armstrong didn't talk about the future in his 19-minute discourse, Aldrin dragged his commander onto the Mars bandwagon anyway. "It was a great personal honor to walk on the moon, but as Neil once observed, there are still places to go beyond belief," he said. "Isn't it time to continue our journey outward, past the moon?"

BEIJING, July 20 (Xinhua) -- As astronomy lovers around the world flood China for the July 22 solar eclipse, the country's National Meteorological Center Monday warned of rain and heavy cloud cover in the area where the total eclipse will be most visible.

Thundershowers or thick clouds may overcast many cities in the Yangtze River Valley, including Shanghai, Chongqing and Wuhan as well as the eight sites with the best views recommended by the National Astronomical Observatories, according to local weather stations.

Jiaxing City, eastern China's Zhejiang Province, is one of the places where the eclipse can best be observed. All its hotels and inns are fully booked by eclipse watchers, 6,000 of whom traveled from abroad, according to local tourism administration.

"We have never seen such a huge number of foreign tourists flocking in," said Zhou Hongxia, deputy director of the local tourism administration.

Enthusiastic eclipse observers should prepare themselves for possible bad weather, said Su Yi, head of Tianjin Astronomical Society.

"Of course, a sunny day will be optimal," he said, as observers can enjoy a panoramic view of the corona, Bailey's beads and the backdrop of a starry sky, he said.

Rain or shine, the observer will still experience darkness and may even see the eclipse vaguely through the clouds, said Su.

National Astronomical Observatories have placed a number of live studios within the totality path. In the worst case, people can watch the scene via live coverage on TV or on the Internet, as long as one studio can observe the scene.

ESA: Man will return to Moon by 2020 or 2025

PARIS, July 20 (Xinhua) -- Man will go back to the Moon by 2020or 2025, Director-general of the European Space Agency (ESA) Jean-Jacques Dordain said on Monday, adding that Europe will play a role in the international mission.

In his statement published on the website of the ESA, Dordain talked about the significance of the 40th anniversary of Apollo 11's landing on the Moon and of the continuing lunar exploration.

Dordain said the Moon could be seen as a part of the human environment, which would be used "to make scientific progress, to establish a warning system against asteroids or anything else threatening Earth, or to be a source of resources to take back to Earth."

"I am sure humans will return to the Moon, but they will go to the Moon together and not in the context of two competing countries," he reiterated.

"I think Europe will play a part in the international exploration of the Moon," Dordain said.

Dordain believed that the lunar exploration mainly depends on the current U.S. plan, which is expected to land a crew on the Moon by 2020.

"I am absolutely convinced that mankind will go back to the Moon in 10 years' time, or maybe 20 years, but that is not the most important point. We're not talking about a race. If it's not in 2020, it will be in 2025 -- it doesn't really matter," Dordain said.

NASA to help promote "green" project in Los Angeles

LOS ANGELES, July 20 (Xinhua) -- NASA's Jet Propulsion Laboratory (JPL) will help develop technology to reduce water usage and greenhouse gas emissions in Los Angeles, Mayor Antonio Villaraigosa announced on Monday.

"This partnership will harness Los Angeles' unparalleled creative capital and entrepreneurial spirit to develop clean and green technologies that will spur job growth across the board from research, development, construction and finance," Villaraigosa said after signing the memorandum of understanding to at JPL in Pasadena, Los Angeles.

JPL director Charles Elachi said: "We are proud that JPL technology and expertise will be part of this collaboration to help improve energy efficiency and protect our water supply 鈥?one of our most precious natural resources."

Under the terms of the three-year agreement, staff at JPL and its managing institution, California Institute of Technology (Caltech), will use their expertise in climate-change science, remote sensing and in other fields to help develop technologies to improve energy efficiency, increase the use of renewable energy sources, conserve water and reduce greenhouse gas emissions.

"We aim to develop real-world solutions based on unparalleled scientific expertise," said David Nahai, General Manager of Los Angeles Department of Water and Power (DWP) which will take part in the "green" project.

The plan will also require JPL and Caltech to work with local universities such as University of Southern California (USC) and University of California in Los Angeles (UCLA) to make technology assessments, develop models, and provide data on global change from Earth science satellites and ground-based instruments.

One project already being investigated could have immediate applications to Southern California's critical water shortage, DWP officials said.

Much of the DWP's water supply comes from the Owens Valley via the California Aqueduct. The department's vast land holdings include Owens Lake, an ancient dry lakebed whose blowing dust can impact air quality for Owens Valley residents.

To help reduce dust, the DWP and its team of contractors are installing a computer-controlled network of sprinklers currently covering more than 14 square miles of the lakebed. But the flooding system consumes significant amounts of water.

JPL and Caltech are working on developing a remote sensing instrument that would measure the lakebed's surface moisture in order to precisely ascertain when water needs to be applied. It would lead to more efficient use of the Owens Lake sprinkler system and conserve water resources.

JPL and Caltech are in the process of developing technology that would make more efficient use of that diminishing water supply.

Other projects aim to reduce agricultural energy and water consumption; predict the availability of solar, wind and wave energy resources; develop communications architectures for smart grid applications; and develop efficient technologies for pre-processing food waste used to produce biogases and renewable energy.

Solar eclipse view may be hurt by clouds, rain

SHANGHAI: Those who were looking forward to seeing the total solar eclipse on Wednesday may be disappointed because of rain and clouds.

Officials at China's National Meteorological Center predicted Monday that the cities that had been widely regarded as the ideal places to watch the rare astronomical event, including Shanghai, Hangzhou, Nanjing, Hefei and Wuhan, will probably experience rainfall or cloudy weather on Wednesday.

"This indeed will be a great pity if the rare event is ruined by rain or cloudy weather on Wednesday morning," an expert from Shanghai Astronomical Observatory said. "But cities will still be plunged into four to six minutes of darkness by the full eclipse."

An official from the Shanghai Tourist Transport Center said Monday people who bought a tour ticket to watch the eclipse could receive a refund if the rare event is rained out.

The center began selling eclipse tour packages last month with a price of 150 yuan ($22) per person. So far, more than 1,500 tickets have been sold for the eclipse viewing at Yangshan Deep Water Port, which is reported to be a prime viewing spot in the city.

The Shanghai Greenery and Public Sanitation Bureau has decided not to turn on landscape lighting during the total solar eclipse after people said the lights could affect eclipse viewing.

The National Astronomical Observatories have also placed a number of live studios within the path of the eclipse. In the worst case, people can watch the scene via live coverage on TV or on the Internet.

Most of central China will be covered by a shadow when the moon moves between the Earth and sun. The rest of the country will see a partial eclipse at that time, he added.

The eclipse will be the longest in China in centuries. A large part of China will be covered and areas along the Yangtze River - including Jiangsu, Zhejiang, Anhui, Hubei and Sichuan provinces, as well as Chongqing municipality - are among the best observing places.

People there can observe four to six minutes of total eclipse. It is the longest one in the past 2,143 years, according to Li Ding, a professor from Chinese Academy of Sciences.

Zhao Guang, deputy head of the National Astronomical Observatory said people can witness a total solar eclipse once every 300 years in the same spot and it usually lasts only about three minutes.

Heat waves

Shanghai Meteorological Bureau issued the highest heat alert Monday as the city's temperature rocketed to 40 C.

The red heat alert was the first issued this year. The city's weather bureau suggested people stop all outdoor activities and called for heatstroke prevention.

Heat alerts are issued in one of three levels: red, orange and yellow. The red alert is the highest and is issued only when the mercury rises above 40 degrees.

Monday was the eighth day in succession with the temperature higher than 35 degrees. The city upgraded the heat alert from yellow to orange on Sunday when the high temperature peaked at 37.7 degrees in downtown areas.

Bureau officials said the temperature would drop to 35 degrees on Tuesday. The rain on Tuesday night will bring the temperature down to about 30 degrees on Wednesday.

Monday in Beijing, residents also suffered from "sauna weather" - a mixture of heat and humidity - and such weather is expected today as well.

Although the highest temperature hit only 34 C Monday, people felt very uncomfortable because of the high humidity, an official at the local meteorological bureau said.

Residents should avoid outdoor activity during the noontime to prevent sunstroke, the meteorologist said.

Spanish experts to study solar eclipse in China

MADRID, July 20 (Xinhua) -- A group of more than 20 Spanish scientists are now in China to study this century's longest solar eclipse, official sources said Monday.

The Spanish experts are expected to observe and tape record the rare phenomenon that will occur Wednesday in China, said the sources with the regional government in Extremadura, west of Spain.

The group, led by astronomer Miquel Serra-Ricart, a member of the International Astronomical Union, is composed of experts on astronomy, communications and informatics.

Along with the experts, some young Spanish students also got the chance to visit China and its scientific facilities, the sources said.

Spacewalk No. 2 unfolds on 40th moon anniversary

The astronauts aboard the shuttle-station complex celebrated the 40th anniversary of man's first moon landing with their own spacewalk Monday, heading outside to stockpile some big spare parts.

In the second outing of their mission, David Wolf and Thomas Marshburn anchored a 6-foot dish antenna on the international space station for future use, then did the same with a hefty pump and an engine for a rail car.

The spacewalk unfolded 40 years to the day that two other astronauts 鈥?Neil Armstrong and Buzz Aldrin 鈥?strolled the moon's dusty surface. It was the 202nd spacewalk by Americans since the Apollo 11 lunar excursion.

Inside Mission Control, a clock counted down to 4:17 p.m. EDT, the moment the Eagle set down on the Sea of Tranquility on July 20, 1969. It wasn't until two hours later, as the spacewalk was ending, that the astronauts made note of this "special day."

Earlier in the day at a Washington news conference, some of the Apollo astronauts, including Aldrin, suggested the $100 billion poured into the space station had not yielded much and that the outpost would be better used as a testbed for human missions to Mars and even asteroids.

"We've spent a lot of money up there for almost nothing," said Apollo 13 commander Jim Lovell. "It's almost a white elephant and until we can really get a return on our investment of that particular project, then it was money wasted."

Meanwhile, the $15.6 million space station toilet that broke down Sunday was up and running again, after the crew added some new parts.

The commode 鈥?one of three on the linked station and shuttle Endeavour 鈥?was out of action for about 24 hours.

NASA wanted the station commode working again as soon as possible. With a record number of people on board 鈥?13 鈥?having three working toilets is crucial.

Complicating matters was the fact that Endeavour cannot eject any waste water while it's docked to the space station. The water would spray all over the porch attached two days ago to the Japanese lab, and possibly corrode it. With the toilet fixed, there was no longer any worry about coming close to filling Endeavour's waste water tank.

There were a few moments of concern midway through the seven-hour spacewalk, however, when Marshburn reported that one of the hooks on his safety tethers was not anchored to the station. The antenna work was held up while he reeled his 85-foot tether back out, trying not to drag the line against critical equipment. Despite everything, he remained connected to the station the entire time.

The antenna and other spare parts that were attached to the space station were hauled up by Endeavour. It was grueling work for the spacewalkers because of the tight clearances.

NASA wants to have as many extra pieces up there as possible so that when the shuttles stop flying next year, the station will be able to get along without their big deliveries. None of the other spacecraft that visits the outpost can hold nearly as much cargo as the shuttle.

Monday's spacewalk was much quieter than the one Saturday. Loud static filled the airwaves throughout the earlier excursion, the result of improperly positioned microphones in an astronaut's helmet. The cap with those microphones will not be used again.

Three more spacewalks are planned during Endeavour's station visit, which ends July 28.

Russia launches two satellites

MOSCOW, July 21 (Xinhua) -- Russian Space Forces launched two satellites on Tuesday from the Plesetsk space center in northern Russia, news agencies reported.

The Cosmos-3M rocket carrying a military satellite and a new civilian satellite named Sterkh blasted off at 07:57 a.m. Moscow time (0357 GMT), and is scheduled to put the satellites into orbit at 09:00 a.m. Moscow time (0500 GMT).

The Sterkh satellite is designed for the Russian part of the international space search and rescue system COSPAS-SARSAT, aide to the Space Forces commander Lt. Col. Alexei Zolotukhin told Interfax.

Russia has carried out 17 successful space launches since this year, said the RIA Novosti.

Australian scientists find tomato gene to feed millions

SYDNEY, July 21 (Xinhua) -- Australian scientists have found a way to boost crop yields that could help feed and clothe millions of people in a time of climate crisis, according to a report from Australian Associated Press on Tuesday.

Researchers at the University of Newcastle have found that by knocking out a gene from the genetic code of a tomato plant, it grows sweeter fruit and longer-lasting leaves.

Yong-Ling Ruan, from the University's School of Environmental and Life Sciences, said the same technique could be used in a range of plants to boost crop yield and shelf-life.

"With predictions the global population may double over the next 50 years, scientists are concerned about the pressure on the world's natural resources," Ruan said.

"Faced with the impact of climate change and population increases on food supply, our research is helping to meet the challenge of how to sustain and improve crop yield and quality."

Ruan said scientists would need at least another five years to take the technique from the lab to the paddock.

The research was conducted at the Australia-China Research Center for Crop Improvement - a joint initiative of the Universityof Newcastle and the Zhejiang Academy of Agricultural Sciences in Hangzhou, China.

Partial solar eclipse to be seen on July 22 in Pakistan

ISLAMABAD, July 21 (Xinhua) -- A partial solar eclipse can be observed almost from entire Pakistan on July 22, a research association said here on Tuesday.

The Pakistan Space and Upper Atmosphere Research Commission (SUPARCO) said that there will be a total solar eclipse on July 22 which will be visible from India, China, Bhutan, Bangladesh, Japanese Islands and South Pacific Ocean.

According to SUPARCO, this total eclipse will not be visible from Pakistan. However, the partial eclipse can be observed almostfrom entire Pakistan, it added.

The total eclipse will begin at 0051 GMT and continue till 0419GMT.

It has been warned not to look at the sun without wearing proper eye shielding material as solar filter otherwise it can damage the eyesight.

Asia will witness 21st century's longest eclipse

A swath starting in India and crossing Shanghai to southern Japan will be plunged into darkness for about five minutes Wednesday in the longest total solar eclipse that will happen this century.

Japan, which hasn't seen a total eclipse for 46 years, is celebrating with fireworks. An astrologer in Myanmar has warned the eclipse is a sign of impending chaos. In India, some pregnant women have been told to stay indoors to follow a centuries-old tradition of avoiding the sun's invisible rays.

The eclipse will appear first at dawn in India's Gulf of Khambhat just north of the metropolis of Mumbai.

It will move east across India, Nepal, Myanmar, Bangladesh, Bhutan and China before hitting the Pacific. The eclipse will cross some southern Japanese islands and be last visible from land at Nikumaroro Island in the South Pacific nation of Kiribati. Elsewhere, a partial eclipse will be visible in much of Asia.

For astronomers, it will be a chance for a prolonged view of the sun's corona, a white ring 600,000 miles (1 million kilometers) from the sun's surface. The previous total eclipse, in August 2008, was two minutes and 27 seconds. This one will last 6 minutes and 39 seconds at its maximum point.

Solar scientist Lucie Green is aboard an American cruise ship heading for that point near the Japanese island of Iwo Jima, where the axis of the moon's shadow will pass closest to earth.

Passengers paid $2,599 to $3,643 for the cruise run by Mayhugh Travel Inc., a California company that specializes in astronomy vacations, according to the company's Web site.

"The corona has a temperature of 2 million degrees but we don't know why it is so hot," said Green of University College London. "What we are going to look for are waves in the corona. ... The waves might be producing the energy that heats the corona. That would mean we understand another piece of the science of the sun."

Scientists are hoping data from the eclipse will help explain solar flares and other structures of the sun and why they erupt, said Alphonse C. Sterling, a NASA astrophysicist who will be following the eclipse in China.

Man has been recording solar eclipses for 4,000 years, and even today they inspire a combination of fear, fascination and wonder.

In India, hundreds of scientists have started arriving in the village of Taregna in Bihar state, where they hope to avoid the monsoon clouds hanging over much of the country.

Scientists plan to study atmospheric ionization, geomagnetism, asteroids, animal and avian behavior and the impact on microorganisms.

A team led by Dr R.K. Sinha of Patna University will study birds. "The researchers will observe whether they suddenly move back to their nests, sound differently and behave in an unusual manner due to sudden darkness," he said.

A travel agency in India is running a charter flight to watch the eclipse by air.

Some families have advised pregnant relatives to confine themselves to curtained rooms, following long-held fears that the invisible rays would harm the fetus and the baby born with disfigurations, birthmarks or a congenital defect.

"I've been told to lie straight on the bed with my eyes open and to chant prayers and verses from the Hindu holy texts during the eclipse," said Sonya Chadha, a New Delhi accountant who is seven months pregnant and plans to take the day off. "If even a tiny sliver of light falls on me, it could harm my child."

In Japan, where the last total eclipse happened in 1963, people are flocking to the small island of Yakushima, which is holding a a two-day festival with fireworks, dancing, grilled squid and cotton candy. The island's 180 hotels are fully booked. A partial eclipse will be visible in Tokyo.

What is solar eclipse

Illustration. [China Daily]

A solar eclipse can occur only when the New Moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic-hence the name.

The Moon's orbit around the Earth is inclined at an angle of just over 5 degrees to the plane of the Earth's orbit around the Sun (the ecliptic). Because of this, at the time of a New Moon, the Moon will usually pass above or below the Sun. A solar eclipse can occur only when the New Moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic-hence the name.

Motion of the Moon and Earth

The Moon's orbit is also elliptical, which means that the distance of the Moon from the Earth can vary by about 6% from its average value. This means that the apparent size of the Moon is sometimes larger or smaller than average, and it is this effect that leads to the difference between total and annular eclipses (the distance of the Earth from the Sun also varies during the year, but this is a smaller effect). On average, the Moon appears to be slightly smaller than the Sun, so the majority (about 60%) of central eclipses are annular. It is only when the Moon is closer to the Earth than average (near its perigee) that a total eclipse occurs.

The Moon orbits the Earth in approximately 27.3 days, relative to a fixed frame of reference. This is known as the sidereal month. However, during one sidereal month, the Earth has moved on in its orbit around the Sun. This means that the average time between one New Moon and the next is longer, and is approximately 29.6 days. This is known as the synodic month, and corresponds to what is commonly called the lunar month.

The Moon crosses from south to north of the ecliptic at its ascending node. However, the nodes of the Moon's orbit are gradually moving in a retrograde motion, due the the action of the Sun's gravity on the Moon's motion, and they make a complete circuit every 18.5 years. This means that the time between each passage of the Moon through the ascending node is slightly shorter than the sidereal month. This period is called the draconitic month.

Finally, the Moon's perigee is moving forwards in its orbit, and makes a complete circuit in about 9 years. The time between one perigee and the next is known as the anomalistic month.

Frequency of Solar Eclipses

The Moon's orbit intersects with the ecliptic at the two nodes that are 180 degrees apart. Therefore, the New Moon occurs close to the nodes at two periods of the year approximately six months apart, and there will always be at least one solar eclipse during these periods. Sometimes the New Moon occurs close enough to a node during two consecutive months. This means that in any given year, there will always be at least two solar eclipses, and there can be as many as five. However, some are visible only as partial eclipses, because the umbra passes either above or below the earth, and others are central only in remote regions of the arctic or antarctic.

Path of an Eclipse

During a central eclipse, the Moon's umbra (or antumbra, in the case of an annular eclipse) moves rapidly from west to east across the Earth. The Earth is also rotating from west to east, but the umbra always moves faster than any given point on the Earth's surface, so it almost always appears to move in a roughly west-east direction across a map of the Earth (there are some rare exceptions to this which can occur during an eclipse of the midnight sun in arctic or antarctic regions).

The width of the track of a central eclipse varies according to the relative apparent diameters of the Sun and Moon. In the most favourable circumstances, when a total eclipse occurs very close to perigee, the track can be over 250 km wide and the duration of totality may be over 7 minutes. Outside of the central track, a partial eclipse can usually be seen over a much larger area of the Earth.

How to observe

No matter whether you are an experienced astrophotographer, or a novice with a camera in hand, you can have beautiful photographic memories of a total solar eclipse.

Here are some pointers:

Both digital and film cameras can capture solar eclipses. It is better if you choose 35mm single lens reflex cameras with manual control over shutter speeds. The shutter speed range should be from 1 second to 1/1000 second. Lenses with a focal length of 400mm to 1000mm, f/5 to f/8, are best. However, point-and-shoot cameras with wide-angle lenses are also excellent for capturing the quickly changing light in the seconds before and during totality.

If you use a long lens to photograph the sun, be warned that any vibration of the camera will ruin the image. Stabilize your camera before the solar eclipse happens. Use the sturdiest tripod you can. Changes in shutter speed may cause vibrations.

Disable the camera's auto focus function before you begin your eclipse shots. Make sure the lens is focused on infinity when the eclipse is occurring. Auto focus will result in out of focus pictures, or no picture at all if the camera shutter does not release.

Flash lights up the immediate environment, but it will not work if your intent is to light up the dark side of the moon during totality. Flash bulbs and other flash attachments are not suggested during the solar eclipse.

Remove the solar filter in order to get something on film during the eclipse from the time you can first look at the eclipse (the second contact of the sun and the moon) until the final diamond ring (the third contact). But for the rest of the time, make sure the solar filter is attached. Do not panic when removing it.

Safety first. You need special solar filters to protect your eyes and camera. Do not gaze into the viewfinder before the eclipse begins, or you may blind yourself.

China Exclusive: China aims to record 40-minute image of solar eclipse corona

Graphics shows the solar eclipse lasting for over six minutes on July 22, according to the Chinese Academy of Sciences Purple Mountain Observatory.

NANJING, July 21(Xinhua)-- Chinese scientists are striving to capture a 40-minute sequence of images of the corona of a solar eclipse along its path across China on Wednesday in a bid to understand the sun's outer atmosphere.

"We have set up 17 observer stations along the central line of the solar eclipse in China to capture the corona images," said Ji Haisheng, an astronomer with the Chinese Academy of Sciences (CAS) Tuesday.

"If weather permits, we are very likely to get the first-hand materials for the solar corona research.

"The corona is the sun's outermost atmosphere, which is relatively dim, and can only be observed through a coronagraph on a normal day," said Ji, a research fellow with the CAS Purple Mountain Observatory based in Nanjing, eastern Jiangsu Province.

A coronograph is an instrument that is designed to block light from the main solar surface in order to observe the corona.

"However, it can be easily seen during a total solar eclipse, as the brighter parts of the solar atmosphere are shadowed."

The 17 stations were set up in the solar eclipse path from southwestern Yunnan Province to eastern coastal Zhejiang Province, which runs through 2,500 km across China, he said.

He said CAS scientists hoped the corona images could be captured by all 17 video monitors, so that they showed the full path of the solar corona.

"The corona could have a tremendous influence on the Earth, but it remains a puzzle. It has become an interesting research focus for astronomers around the world," Ji said.

Scientists have observed that when a solar wind erupts across the surface of the sun, a result of the coronal mass ejections (CMEs) or eruptions of material from the sun, communication signals on the Earth could be disturbed.

The total solar eclipse on Wednesday has been forecast by the CAS to be the longest observable in China between 1814 and 2309. Viewed from the best observation spots, the total eclipse can last more than six minutes.

"Astronomers from all over the world are heading to China to observe the corona. We will work closely and share each other's statistics and data on solar eclipse observations," said Gan Qunwei, deputy chief of the Purple Mountain Observatory.

Jagdev Singh, of the Bangalore-based Indian Institute of Astrophysics, said he would be studying the corona chromospheric lines and the corona polarization.

The corona is separated from the sun's photosphere by relatively shallow chromosphere. However, scientists have not found the exact mechanism by which the corona is heated. The studies on chrompheric lines and the polarized radiation have helped give clues to the magnetism of the solar atmosphere.

Singh is accompanied by 30 students from the institute, bringing two tons of observation instruments to the observatory in Jiangsu for the solar eclipse.

Bad weather may spoil eclipse viewing in India: official

VARANASI, India, July 21 (Xinhua) -- While India is waiting for the longest eclipse of the century to take place Wednesday morning in the country, weather may spoil the exciting natural event in several places including Uttar Pradesh and Madhya Pradesh, situated within the eclipse belt, with heavy clouds or rains, said Indian meteorological officials Tuesday.

The Uttar Pradesh Meteorological Department said cloudy skies and thundershowers in several places, including Varanasi, Lucknow and Allahabad, could hamper the viewing activities.

Low pressure area over northwest Bay of Bengal has concentrated into a depression and is expected to move towards the Uttar Pradesh bringing rains in some parts of the state, said the officials.

In Varanasi, a Hindu holy city, the maximum totality duration of the eclipse would be three minutes and 10 seconds from 5:28 a.m. Wednesday, while in the state capital Lucknow the eclipse begins at 5:31 a.m. and ends at 7:26 a.m.

The Indira Gandhi Planetarium and the Regional Science City in Lucknow will open at 5 a.m. Wednesday for visitors and show the fantastic view live from 5:31 a.m. on a large LCD screen.

By the 12th century sun worship was a major part of Hindu Rituals, said Willard Van de Bogart, an American astrologer.

"What makes this solar eclipse so unique is that it is occurring at the end of the great year which is known as the precession of the equinoxes, which means over a period of 26,000 years the sun will finally return to its starting point where it crosses once again the galactic equator," Van de Bogart told Xinhua.
