Cracks Found in Shuttle's Tank Foam
NASA officials still puzzling over what caused a section of foam
insulation to break away from the space shuttle Discovery's external
fuel tank during its launch in July, have found nine new unexplained
cracks in the foam of another tank at the Louisiana plant where
the foam is applied.

Delays Next Shuttle Launch to Address Falling Foam
In light of what they learned from the space shuttle's return
to flight and the reoccurring problem of foam breaking off the
external fuel tank during takeoff, NASA officials said they will
hold off launching the next shuttle until the spring of 2006.

Discuss Discovery Mission, NASA's Next Steps
Despite unexpected repair missions and two days of foul weather
that delayed its return, the shuttle Discovery and its crew of
seven astronauts safely landed at Edwards Air Force Base Tuesday
morning. Two experts discuss the shuttle's return and what comes
next in NASA's space program.

Discovery Crew Makes In-flight Repairs
Astronaut Stephen Robinson gently plucked two protruding and potentially
dangerous fiber strips from the space shuttle Discovery's underbelly
Wednesday in an unprecedented emergency repair. Kathryn Sullivan,
the first American woman to conduct a spacewalk in 1984, discusses
the intricacies of the repair mission.

Considers In-space Shuttle Repair
NASA scientists are considering whether or not Discovery's astronauts
should be the first to try a spacewalk to fix the outside of the
shuttle while it is in orbit. The goal: to remove filler material
between the shuttle's protective thermal tiles. The gap filler
could disrupt air flow during re-entry and lead to dangerous overheating.
Keith Cowing, editor of NASA Watch, discusses whether a spacewalk
is needed to repair damage to the shuttle’s underside.

to Ground Shuttles over Foam Debris
NASA said Wednesday it would ground future shuttle flights because
the problem of foam peeling off the fuel tank and possibly damaging
the shuttle had not been eliminated. During Discovery's launch
Tuesday, a large piece of the insulating foam broke off the tank
but did not put the shuttle in danger as it did during the January
2003 liftoff of the shuttle Columbia.
