US shuttle plan changed after tools float off

NASA controllers are revamping plans for the remaining spacewalks set to take place during space shuttle Endeavour’s visit to the international space station, after a crucial tool bag floated out to space during a repair trip.

The briefcase-sized tool bag drifted away from astronaut Heidemarie Stefanyshyn-Piper yesterday as she cleaned and lubed a gummed-up joint on a wing of solar panels on the space station.
