Astronauts Prepare for Spacewalk to Remove Gap Filler - Universe Today
Astronauts Steve Robinson and Soichi Noguchi made their preparations to head outside the space shuttle Discovery today. This spacewalk had been planned for the mission, but shuttle managers gave the two men the additional task of fixing two protruding gap fillers in between the heat tiles on the underside of the shuttle. Robinson will attempt to pull the excess material out by hand, or use a hacksaw if that doesn't work.
