Even in space, duct tape may work wonders.
Astronaut Piers Sellers has suggested using some duct tape to fix a safety-jet backpack, after it nearly came loose from him in the middle of his spacewalk yesterday. Sellers' spacewalking partner, Mike Fossum, had to tether the backpack to Sellers to keep it from flying away.
NASA officials say Sellers was never in danger of losing the backpack, which allows astronauts to propel themselves to safety in
an emergency. Discovery pilot Mark Kelly has told ground controllers he thinks he knows how the pack's latches came loose -- from bumping around inside the shuttle's crowded payload bay.
Sellers and Fossum are to make a third spacewalk tomorrow.
