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 11, 2013 The European Space Agency's probe has spent the last decade doing flybys of Earth and Mars to match comet 67P/Churyumov-Gerasimenko's speed.
December 9, 2013 "It's the kind of water where if you were really dying, you could drink it, but you probably wouldn't bottle it for resale," says the chief scientist of the Curiosity mission. Scientists say the lake could have sustained life billions of years ago.
December 8, 2013 California-based Moon Express just unveiled the design for a small robot spacecraft about the size of a coffee table that it says could move about the moon's surface powered only by solar panels and hydrogen peroxide.
December 3, 2013 The company's Falcon 9 booster lifted off from Cape Canaveral, Fla., carrying the satellite into a geostationary orbit.
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.
December 3, 2013 Imagine stepping into an elevator and bumping into your greatest hero. What would you say? Commentator Adam Frank had this happen with one of the 20th century's greatest astronomers, a seer of sorts.
December 2, 2013 The mission has become a reason for national pride in the country. If successful, China would join the U.S. and the former Soviet Union as the only countries to achieve a soft landing on the moon.
November 29, 2013 The Comet ISON appears to have survived after disappearing and being thought dead. New NASA photos show the comet emerging from behind the sun smaller and dimmer, but still throwing a big light trail.
November 28, 2013 Most of ISON, a huge comet formed at the birth of the solar system, apparently did not survive Thursday's encounter with the sun, NASA said. Scientists detected the comet last year and had hoped to continue studying it for information to be mined from its "primordial ices."
November 28, 2013 Space will serve up a banquet of activities on Thanksgiving, featuring a comet kissing the sun, a zero-gravity freeze-dried feast in orbit and a rocket launch attempt.
November 26, 2013 Astronomers will turn skyward to glimpse ISON, an unusual comet from the outermost edge of our solar system that is now plunging toward the sun. ISON could yield clues to the formation of the solar system, and may become visible to the naked eye in December — if it survives.
