NASA has released photographs that show how the space shuttle
Atlantis
suffered damage from hot gases back in May 2000 when it returned through the atmosphere on a mission. The damage wasn't permanent and repaired in time for its next mission four months later. NASA blamed the damage on improper installation of a seal between protective panels on the shuttle's left wing.
Atlantis
is expected to be the first shuttle to return to space when NASA begins launches again in early 2004.
