Data from a comet-bound NASA probe, a robotic mission to Saturn, and a U.S. instrument aboard an Indian spacecraft have provided clear evidence that at least trace amounts of water exist on the moon's surface, researchers said Thursday.

While scientists have long suspected that water ice from comet impacts is trapped in cold, permanently shadowed craters near the moon's poles, the new data indicates that water molecules form and dissipate across broader areas, even in lunar daylight.

While the data represent a major surprise and a "really profound discovery," one scientist said, researchers cautioned that … Read more

KENNEDY SPACE CENTER, Fla.--Chief astronaut Steven Lindsey, a veteran of four shuttle missions, will command an all-veteran six-member crew for the final planned space shuttle flight next year, NASA announced Friday. Peggy Whitson, an experienced space station commander, will take over as chief astronaut as the shuttle program winds down.

Lindsey will be joined by pilot Eric Boe and mission specialists Benjamin "Al" Drew, Michael Barratt, Nicole Stott, and Timothy Kopra, all space veterans. Barratt and Stott are currently in orbit aboard the International Space Station while Kopra just returned from a long-duration stay.

After two months of checkout and calibration, NASA's $504 million Lunar Reconnaissance Orbiter was maneuvered into a circular 31-mile-high mapping orbit Tuesday, and scientists said Thursday the spacecraft's instruments are delivering intriguing clues about the possible presence of water ice.

"The moon is starting to reveal her secrets, but some of those secrets are tantalizingly complex," said Michael Wargo, NASA's chief lunar scientist.

Scientists expected the spacecraft to find signs of hydrogen--an indicator of possible water ice deposits--in permanently shadowed craters near the moon's south pole. Ice could be expected from cometary impacts over … Read more

Japan's new HTV cargo ship, carrying more than 7,000 pounds of supplies and equipment, was plucked out of open space by the International Space Station's robot arm Thursday to complete a near-flawless automated rendezvous marking a major milestone for the station program.

Arm operator Nicole Stott, working inside the Destiny laboratory module, locked the station's space crane onto the HTV cargo ship at 3:47 p.m. EDT as the two spacecraft moved into orbital darkness 220 miles above Eastern Europe.

"It's a real example of international cooperation with a Japanese vehicle captured by … Read more

They pissed it. You may have missed it.

Recently, there was a fascinating glow in the sky that moved observers to ponder just what it might be.

I am assuming that Space.com is an authoritative source of information, for it informs me that the glow that was seen in the sky by so many last Wednesday was, indeed, astronauts' urine.

NASA spokeswoman Kylie Clem told a press conference that this aurora boreapiss was the result of the space shuttle Discovery releasing an unusual amount of water and urine into outer space.

I have never consciously weighed urine--not even my … Read more

NASA's embattled Constellation moon program, thought by many to be on life support in the face of ongoing budget cuts, is technically feasible, "soundly" managed, and capable of putting American astronauts back on the moon as planned in the 2020s, the chairman of a manned space review said Tuesday.

But if the Obama administration and Congress fail to restore some $3 billion in lost funding, he said, NASA will be unable to return to the moon or venture beyond the confines of low-Earth orbit.

Norman Augustine, former CEO of Lockheed Martin and chairman of Review of U.… Read more

Detoured by bad weather in Florida, the shuttle Discovery dropped out of orbit and swooped to a flawless California landing Friday to close out a successful space station resupply mission.

Shuttle commander Frederick "C.J." Sturckow and pilot Kevin Ford fired the shuttle's twin braking rockets at 4:47 p.m. PDT to drop the ship out of orbit for an hour-long descent to Edwards Air Force Base.

After a steep plunge across the Los Angeles basin, Sturckow took over manual control at an altitude of about 50,000 feet above the Mojave Desert landing site and … Read more

With the future of NASA's embattled moon program in doubt, Alliant Techsystems test-fired a huge five-segment solid-fuel booster in Utah Thursday, a ground-shaking demonstration designed to collect performance data for a new rocket intended to replace the space shuttle.

Generating 22 million horsepower, the lengthened 154-foot-long shuttle booster ignited with a torrent of flame at 3 p.m. EDT, sending a towering column of dirty brown exhaust into the Utah sky as hundreds of spectators looked on. Two minutes later, after consuming 1.4 million pounds of solid propellant, the rocket burned out.

"After witnessing what we just … Read more

The Japanese space agency launched a powerful new rocket Thursday carrying an unmanned space station cargo ship on a complex maiden voyage to deliver some 7,400 pounds of equipment and supplies to the orbital outpost.

With four strap-on boosters gushing white-hot exhaust and a pair of hydrogen-fueled main engines roaring at full throttle, the H-2B rocket thundered away from launch pad 2 at the Tanegashima Space Center in southern Japan at 1:01:46 p.m. EDT.

"The launch was beautiful," Stephen Clark, a U.S. journalist representing Spaceflight Now, said in an instant message from Tanegashima. &… Read more
