NASA is aiming to launch a rocket to an asteroid in five years and grab a boulder off of it — a stepping stone for an eventual trip sending humans to Mars.

NASA is blaming Congress for the need to pay $424 million more to Russia to get U.S. astronauts into space.

Virgin Galactic is one flight closer to becoming a commercial "spaceline." The company's passenger spacecraft, SpaceShipTwo, completed its first rocket-powered flight Monday morning above the Mojave Desert in California.

A Dutch company is now accepting applications for brave men and women who would like to go to Mars.

Europe's Herschel space telescope has imaged one of the most popular subjects in the sky - the Horsehead Nebula - and its environs. The distinctively shaped molecular gas cloud is sited some 1,300 light-years from Earth in the Constellation Orion.

A British astrobiology conference has revived a years-old debate over the best place to look for life elsewhere in the solar system: Mars, or the moons of Jupiter and Saturn? "For reasons I don't really understand, the wider solar system and the potential for life there has not been high priority," The Telegraph quoted Robert Pappalardo, a senior research scientist at NASA's Jet Propulsion Laboratory, as saying on BBC Radio 4.

NASA's Curiosity rover results confirm that Mars has lost most of its atmosphere, on its way to becoming a cold, dry planet. In experimental results reported Monday at a European geoscience meeting in Vienna, Austria, a look at the Martian air by the $2.5 billion rover finds evidence that as much as 90% of the original atmosphere there has dissipated into space over the planet's lifetime. "It was still red, but it means that Mars once was a warmer, wetter world," says rover team scientist Sushil Atreya of the University of Michigan. "It was also a more habitable world, essentially four billion years ago."

NASA is planning for a robotic spaceship to lasso a small asteroid and park it near the moon for astronauts to explore, a top senator revealed Friday.

New results from a look into the split second after the Big Bang indicate the universe is a bit older than previously thought but the core concepts of the cosmos - how it began, what it's made of and where it's going - seem to be on the right track....

More than 35 years after it launched on a mission to explore the cosmos, NASA's unmanned Voyager spacecraft appears to have left the solar system and is in a "new region" of space, said a study Wednesday.
