December 17, 2013 The spacewalks are to repair a bad valve in a pump that has caused problems with the station's cooling system.
December 11, 2013 One of two systems used to dissipate heat from the station's onboard system is acting up, but the space agency says it's not a dangerous situation for the moment.
December 3, 2013 The space agency has announced plans to grow turnips, basil and cress on the moon by 2015. The experiment could be good news for astronauts sick of their freeze-dried fare. But researchers say the real goal is to see if humans could one day live — and farm — on the moon.
November 25, 2013 Once again, there's talk about a possible "comet of the century." Will ISON be a thriller or a dud? It's due to whiz by the sun on Thanksgiving Day. If it holds itself together after that, the comet could put on a stellar show in December.
November 22, 2013 A gamma-ray burst observed by orbiting telescopes this year was "a once-in-a-century cosmic event," says a NASA astrophysicist. Now the space agency has produced an animated video to show what it looked like.
November 20, 2013 The first satellite ever developed by high school students to make it to space is believed to be orbiting Earth after getting a ride aboard a U.S. military rocket Tuesday night from Wallops Island, Va. Fittingly, perhaps, you can send it a text message.
November 18, 2013 The robot orbiter will take 10 months to reach the red planet, where scientists hope it will solve an enduring mystery about radical climate change in Mars' distant past.
November 5, 2013 India launched its first-ever probe to the red planet on Tuesday at a cost of one-tenth what NASA is expected to pay for its latest Mars mission.
October 21, 2013 The blastoff of the Minotaur I, operated by Orbital Sciences Corp., has been pushed back after preparations were put on hold during the government hiatus. When it does blast off, it will launch 29 satellites into low Earth orbit, a new record for the most payloads ever deployed from a single rocket.
October 14, 2013 The budget negotiations in Washington are not front-page news on Mars. There, NASA's rovers continue to operate, taking photographs and collecting data as they prepare for the coming Martian winter.
October 9, 2013 NASA's Juno space probe has traveled about 1 billion miles on its course to reach Jupiter in 2016. Yet it's nearly back where it started — Juno will be 347 miles away from Earth on Wednesday afternoon.
October 3, 2013 With the space agency largely grounded, employees Karen Nyberg and Mike Hopkins continue to orbit 250 miles above Earth aboard the International Space Station. While it's not clear they have all that much to do, their Twitter feeds show they may be getting creative — and perhaps a bit bored.
October 1, 2013 The National Zoo's Panda Cam and the Bureau of Land Management's wild horse and burro adoption program are also among the federal government services that have been affected by the shutdown.
