...ROBINSON IN ANY DANGER DURING HIS SPACEWALK? No spacewalk is remotely risk-free. Space suits could be damaged by tools; equipment could malfunction; there?s even the risk of being struck by mictometeors or bits of space debris. But NASA astronauts have been venturing outside of their ships for more than four decades and all of them have come safely back inside...
...pair of pivoting arms by the Canadian group that developed the shuttles' manipulator arm. The most personable is NASA's Robonaut, which has a torso, arms and a head that are adult size and a leg that plugs in for stability and power. The Robonaut was built as a spacewalk assistant to hand astronauts tools and perform the butler-like task of brushing contaminants off their space suits. But with five-fingered hands and cameras for eyes, it may be perfect for the repair job on Hubble. If NASA okays the mission, the agency has until...
...world remembers Mir for its hair-raising string of crises in the late 1990s--culminating in a collision with an unmanned cargo ship in 1997--but there were other, less publicized near misses. Cosmonaut Alexander Serebrov almost became a satellite himself when his safety tether came loose during a spacewalk. Luckily, he managed to grab hold of the station. In 1994, Mir lost its orientation, causing most of its onboard systems to sputter out, including the fans that keep oxygen circulating. To stay alive, the cosmonauts had to wave their hands in front of their faces to gather in breathable...
...International fowl diplomacy aside, scientists continue to debate whether to have the astronauts re-release the orbital satellite they rescued in Monday's spacewalk. While the shuttle may have more than enough turkey, it may be short on fuel to support...
...NASA, this is exactly the image men in space should have: Ordinary guys strapping on the tool belts, doing repair work in orbit. A seven-and-a-half-hour spacewalk ended with astronauts Winston Scott and Takao Doi manually recovering a $10 million satellite that had gone spinning out of control. With the Spartan solar observer now safely in the shuttle cargo bay, astronauts are running tests to see whether the reusable satellite can go out for another 6 to 20 hours of observation before crew members retrieve it and return to Earth.
