Duct Tape Suggested for Spacewalk Repair
CAPE CANAVERAL, Fla. (AP) -- Even in space, a little duct tape may work wonders. Astronaut Piers Sellers suggested using some of the multipurpose sticky material to fix a safety-jet backpack used during spacewalks after it almost came loose from him while he repaired the international space station.
''Right now, is there some kind of tape fix that you guys could think about that would be helpful?'' Sellers asked Mission Control Tuesday morning, a day after the propulsive backpack started to come loose during his spacewalk with astronaut Mike Fossum.
Fossum had to tether the device to Sellers to keep it from flying away.
The jet backpack, nicknamed SAFER, is worn by every astronaut during a spacewalk. It allows an astronaut to propel himself or herself to safety in an emergency, for instance if a tether or foot restraint holding the astronaut in place breaks.
The two connecting devices of Sellers' backpack attachment, designed to be used if an astronaut floats free, loosened at different times, but he was never in danger of losing it, NASA officials said...
...For Wednesday's spacewalk, the astronauts planned to test whether a sealant can be used to repair damaged pieces of the space shuttle's thermal protection system. The technique was developed to make sure there's never a repeat of the Columbia accident that killed seven astronauts in 2003.
The six astronauts of Discovery, along with the three space station crew members, planned to spend most of Tuesday packing up science experiments, trash and unneeded equipment to take back to Earth...
