NASA: Despite run of tough luck, shuttle lands safely

Computerworld - After a grueling and technically intensive 16-day mission in space, the seven-person crew of the space shuttle Endeavour safely touched down at Kennedy Space Center in Florida this morning.

The shuttle landed as scheduled at 10:48 a.m. ET. It was a picture-perfect landing for a shuttle that had a tough time getting off the ground due to a gaseous hydrogen leak that scuttled two scheduled launches and bad weather that derailed three other attempts.

The shuttle finally blasted off on July 15 - its sixth launch attempt.

Yesterday, mission control specialists found that one of Endeavour's forward thrusters, which control altitude and speed upon re-entry, failed during a test of control systems. As shown today, NASA had reported that the shuttle could land safely without the thruster.

Returning from orbit, the shuttle and its crew left behind a new porch for the Japanese laboratory on the International Space Station, new batteries installed to store power collected from the station's solar arrays and several replacement parts to keep on hand. This morning, the shuttle also released what NASA described as two pairs of small research satellites.

The satellites, which had been stored in canisters in the shuttle's payload bay, were both designed and built by students at the University of Texas, Austin, and Texas A&M University. One pair is designed to use GPS data to monitor the rendezvous of orbiting spacecraft. The other pair is designed to measure the density and composition of the rarified atmosphere 200 miles above the Earth's surface, according to NASA.

This was the 127th shuttle mission for NASA and the 23rd for Endeavour, NASA reported today. It also was the 29th shuttle mission to the space station.

The next shuttle mission is scheduled to launch on Aug. 18, when the Discovery is expected to deliver 33,000 pounds of supplies and equipment to the space station.

The world is coming to an end. In, like, 4 billion or 5 billion years. The sun will get old and cranky and eventually immolate the entire planet. The world, however, is not coming to an end on Dec. 21, 2012, contrary to the viral Internet rumor propounded by pseudo-scientists, hoaxers and Hollywood movie promoters. The notion that 2012 heralds the End of Time has something to do with a mysterious Planet X that will supposedly hurtle into, or perhaps merely perturb, Earth. Also, there might be geomagnetic storms, a Pole Reversal and a newfound unsteadiness in the planet's crustal plates. All of that, or variations thereof, can be studied in depth in scores of books now jostling for eschatological primacy with such titles as "Apocalypse 2012," "The World Cataclysm in 2012" and "How to Survive 2012." This is no joke to David Morrison, senior scientist for NASA's Astrobiology Institute. He's counted 200 different books for sale about 2012. As the a

Payette Returns from Space

Astronaut Julie Payette insists Canada's role in the latest shuttle mission is hard to ignore. Payette and the crew of Endeavour returned to Earth Friday morning after a 16-day mission to the International Space Station. Payette calls the mission extraordinary, adding Canada figured significantly on the mission. She noted two Canadian astronauts were involved in the mission and crucial Canadian robotics were part of the work. Payette operated all three robotic arms during the mission: The station's Canadarm2, the Shuttle's Canadarm and the Japanese arm. It was Payette's second mission to the International Space Station. She says it has changed immensely since 1999, adding "my first mission 10 years ago was to a very small space station that only had two modules, nobody on board and yet a lot of work to be done on it."

NASA steps closer to nuclear power for moon base

NASA has made a series of critical strides in developing new nuclear reactors the size of a trash can that could power a human outpost on the moon or Mars. Three recent tests at different NASA centers and a national lab have successfully demonstrated key technologies required for compact fission-based nuclear power plants for human settlements on other worlds. “This recent string of technology development successes confirms that the fission surface power project is on the right path,” said Don Palac, NASA's fission surface power project manager at the Glenn Research Center in Cleveland, Ohio, in a statement. NASA's current plan for human space exploration is to return astronauts to the moon by 2020 on sortie missions that could lead to a permanent outpost for exploring the lunar surface and testing technologies that could aid a manned mission to Mars. The space agency has been studying the feasibility of using nuclear fission power plants to support future moon bases. Engineers
