Space Shuttle Crew Completes Historic Spacewalk

STS-114’s third spacewalk is now in the history books. The excursion featured the first-ever on-orbit repair of a Space Shuttle’s heat shield and attachment of a stowage platform onto the Station.

The heat shield repair efforts occurred quickly and just as planned on Space Shuttle Discovery’s underbelly. STS-114 Mission Specialist Steve Robinson removed gap fillers that were protruding from two areas between heat-shielding tiles on Discovery. Robinson gently tugged the gap fillers until they came out.
