Metals are full of microscopic structures that define properties like strength, but it's hard to figure out how those structures work on Earth, where gravity skews their effects. An experiment aboard the International Space Station may have solved that dilemma, however. By freezing alloys in the s...

It's no secret that scientists want the Curiosity rover to drill into Mars more often. However, it first has to learn how to drill properly -- until now, it was so aggressive that it sometimes broke the rocks it was trying to sample. Thankfully, NASA has a fix. It recently started testing a new dr...

Astronauts can't waste their jetpacks' fuel horsing around, lest they run into trouble, Gravity-style. Instead, they practice on board the ISS with a chunky laptop strapped to their head -- for real. That laptop runs a virtual reality simulator through a VR headset that's far more... substantial t...

We'll soon know if those wrenches the ISS astronauts 3D printed aboard the station are up to par. SpaceX's Dragon has brought the tools back to Earth, along with an assortment of experiment data and samples, on its way home from a resupply mission on February 10th. That means scientists will now b...

NASA's defunct space shuttles have found homes around the US and the 747s that brought them there have also been put to pasture. With no more shuttle carrier aircraft (SCAs), the agency has no more use for the Kennedy Space Center mate-demate facility used to pull the spacecraft off them. The 150-...

If you've been curious about what the other side of the moon looks like, but have been too lazy to look up NASA's findings on your own, this video has got you covered. Based on data from NASA's Lunar Reconnaissance Orbiter, it gives us a close look at the more crater-filled side of the moon (which...

Rovers have a tough time getting across Mars' vast, unforgiving landscape. They can't see very far ahead, and the crew back home can only offer so much help by looking at orbital imagery. NASA's Jet Propulsion Laboratory may have a clever solution to that problem, though: an aerial robot scout. It...

It's not quite a selfie in the traditional sense, but this composite image from 1974 was the first complete shot of the 48 states. It was stitched together from snaps taken by NASA's Earth Resources Technology Satellite, with each picture taken at the same altitude, 560 miles, using only the red p...
