Swiss scientists have developed a robotic arm that can catch items thrown at it with split-second accuracy. Researchers say the new invention, described in IEEE Transactions on Robotics, catches various sized objects within 5/100 of a second. The mechanized arm has three joints, a complex and sophisticated hand with four fingers, and measures about 1.5 […]
Speeding Space Junk Poses Risks for Spacecraft
Posted December 7th, 2012 at 6:11 pm (UTC-4)
The amount of space junk floating around the Earth grows every year, and increasingly can pose risks to spacecraft orbiting the planet. In the United States, NASA’s Orbital Debris Program (ODP) at the Johnson Space Center in Texas, keeps an eye on the ever-expanding junkyard of space. “We define orbital debris as any man-made object […]
