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
