Before they're strapped onto rockets for a mission to Mars, ion engines, like NASA's VASIMR project need to be tested—here at the STG-ET chamber at the German Aerospace Agency (DLR), one of the most advanced vacuum chambers on the planet.
This one is straight out of the annals of Star Trek -- NASA wants to make tractor beams a reality using lasers. They want to trap and pull in small samples remotely, and its not quite as farfetched as it sounds.
The universe is full of incredibly beautiful sights, but they're all designated with dull official codes like NGC 281. Thankfully some stargazers have a little imagination, and have nicknamed the nebula above after the original dot-chomper, Pac-Man. Can you see it?
Our Sun's energy is the source of all life on the planet, sure. But what if it was also the source of the first organic compounds that gave rise to life itself? A team of Hong Kong researchers believe they've proved just that.
Today NASA launched its first weather and climate-forecasting satellite. It's designed to collect environmental data, monitor weather patterns, natural disasters and surface temperatures -- all in the aid of better weather and climate prediction.
A group of amateurs who humbly describe themselves as a "volunteer-based DIY space program" have set a new record for the highest flight of a powered airship, sending one up 18 miles and well on the way to... space.
There's something pretty magical about watching the big blue ball that we call Earth spinning in space. Sit back and watch a stunning compilation of recent orbital fly-bys by the ISS, as it hurtles around our spinning globe. [Space.com]
Otherworldly, out-of-body experiences and alien abductions -- they've been the stuff of legend for decades. Turns out, they're probably just figments of our imaginations and scientists are trying to prove it.
Good news! The ROSAT satellite didn't destroy all humans. Most of it just burned up in the atmosphere, as expected — but not all of it! Nearly two tons of German space junk hit the ocean—and almost China.
ROSAT, the latest man-made object to fall from the heavens and threaten humanity's safety, has apparently burned up in Earth's atmosphere. The 1 in 2,000 chance of death from above we had all feared never materialised.
Launching satellites is a risky proposition — costing as much as £14,000 per kilogram to make orbit with little recourse if it malfunctions. So, DARPA has devised a system to recycle the £190 billion worth of orbiting dead satellites into a zombie antenna array.
