spacecraft

NASA astronauts Edward Lu and Stanley Love first proposed using a robotic spacecraft to nudge space rocks away from Earth using the gentle force of gravity a few years ago. Now a European aerospace giant has begun seriously investigating the concept.

NASA Gets Green: Smart systems and a central computer will keep track of even individual energy efficiency in NASA's Sustainability Base. Don't anger the computer.  NASA

Get ready for the greenest federal building ever built, and maybe also the smartest. NASA plans to channel decades of space exploration technology into its upcoming Sustainability Base in California.

The Japan Space Agency's Kaguya lunar explorer, after a mission that included new geological surveys and lots of gloriously detailed HD footage of the moon's surface, crash landed into a large crater on the moon's near side this week. And JAXA today released its final images, depicting the final moments of its descent. Updated with video.

Japan's Kaguya lunar surveyor craft has sent back fresh HD clips as its orbit slowly degrades, bringing it closer than ever to the surface. In two days it will crash-land, bringing its mission to an end, but until then, it's keeping the ultra-crisp, almost surreal lunar footage coming.

Setting a spacecraft down on Mars isn't exactly easy—just ask Beagle 2. NASA's Phoenix Mars Lander, en route and due for a May 25 rendezvous with the surface, recently received a course adjustment from mission planners as they try to ensure that the craft doesn't drop down in a danger zone.

Japan's space agency gave it the OK. A famous astronaut says he'd get involved. They even tested a prototype in a wind tunnel. Still, it does sound nearly too off-the-wall to be true: Japanese scientists have teamed up with origami experts to design a paper airplane that could withstand re-entry and make its way from space back to Earth.

It's a name only a government agency could love: the Future, Fast, Flexible, Fractionated, Free-Flying Spacecraft United by Information eXchange. Could DARPA possibly come up with a more tortured title for System F6?

The penetrometer was the first thing to hit. The stick-like probe on the bottom of the Huygens lander punched aside a hard pebble made of water ice on the surface of Saturn’s largest moon, Titan, and sliced down through five inches of soft, muddy material. Scientists watching from Earth were ecstatic—the probe was not expected to survive the landing—but at the same time puzzled: If Titan really was, as they suspected, much like a young Earth, where were the liquid oceans predicted to cover the surface?
