If you want to test an aircraft, a race car, a motorcycle, or just about anything that’s going to be slicing its way through the fluid that is air, you put it through wind tunnel trials. But how do you test a spacecraft? If you’re the German Aerospace Center (which goes by its German acronym DLR), you build a “space tunnel”: an 8,344 cubic foot vacuum chamber capable of space-like temperatures hovering just above absolute zero.
Our favorite robot is learning to shop for, prepare and serve entire meals — from cookies to a round of beers and now, breakfast. In this latest robot-cook experiment, PR2 gets some help from a German ‘bot named Rosie, and the pair serves up a traditional Bavarian sausage breakfast.
The robotics engineers at DLR, the German Aerospace Center, have a history of violent behavior with their mechanical creations — earlier this year, we saw them smash a robot's hand with a hammer, and last year we watched brave engineers give a robot a knife and let themselves be stabbed.
After months of calibration and testing, NASA’s flying telescope made its first excursion this morning, and the space agency is looking forward to analyzing the results. But, um, isn’t this sort of blurry?
A Dnepr rocket lifting off from Kazakhstan has successfully launched the second half of the world's most precise 3-D mapping mission of the globe into orbit today, setting in motion a tandem effort that will see two orbiting spacecraft fly in tight formation that will bring them well within 700 feet of each other as they map the earth's topography over the next three years.
Perhaps it's time for Space Ghost to hand over his moniker to the International Space Station (ISS). The orbital outpost makes for an eerie blue shadow in this image taken by a German radar satellite, SPACE.com reports.
The snapshot was taken by Germany's TerraSAR-X satellite on March 13, 2008. But the German space agency only released the startling view of the then-incomplete space station this month.
Energy shields haven't arrived just yet, but this magnetic heat shield could do nicely in the meantime. European researchers have created a magnetic field technology that can protect spacecraft from fiery atmospheric temperatures during reentry, and perhaps cut back on the need for traditional heat shields.
Earthly organisms undergo tests in Mars-like conditions

In a Berlin basement sits a small torture chamber. The air inside the hermetically sealed steel chest consists of a choking 95 percent carbon dioxide, some nitrogen, and traces of oxygen and argon. The pressure within is 1/170 that on Earth, and the thermostat is set to –50˚F—in other words, a nice afternoon on Mars. Experiments at the facility regularly subject some of Earth’s hardiest creatures to this hell, and they do just fine.
