Thetwo astronauts will also install the External Stowage Platform 2 (ESP-2)outside the station's Quest airlock to hold spare parts among their other tasksduring their 6.5-hour spacewalk today.

Discovery Spacewalker to Pluck Gap-Fillersfrom Shuttle's Heat Shield


1 August 2005; 8:17 p.m. EDT


HOUSTON - The crew of thespace shuttle Discovery will perform an unprecedented on-orbitrepair Wednesday, sending an astronaut under the orbiter's belly to removea pair of filler strips jutting out form the spacecraft's tile-covered heatshield, mission managers said Monday.


Thedecision caps three days of scrutiny by imaging specialists, shuttle tile engineers,aerodynamicists and spacewalk planners to determine exactly how to deal withtwo bits of stiff ceramic fiber cloth - known as gap-fillers- sticking from between heat-resistant tiles under the forward section of theDiscovery orbiter.


"Inthe end it came down to be a really simple decision," said Wayne Hale, NASA'sdeputy shuttle program manager, during a briefing here at NASA's Johnson SpaceCenter "We came to the conclusion that we don't know enough to really feel goodabout this, so therefore the remedy is easy and we ought to go exercise theremedy."


Thatremedy is an unprecedented spacewalk to send one astronaut, attached to arobotic arm, under the shuttle to pluck out the strips by hand, or cut them offif they prove too stubborn, spacewalk officials said earlier today.

Spacewalk Goal, Extra Tasks Achieved


1 August 2005; 10:57 a.m. EDT


HOUSTON - With their primaryobjective complete, spacewalking astronauts SoichiNoguchi and Stephen Robinson are retrieving tools they will use for get-aheadtasks.


Afterdisembarking the International Space Station's (ISS) robotic arm, Noguchipicked up a round scoop tool for later use retrieving a broken rotary motor toreturn back to Earth. Engineers want to study the motor before launch andinstalling two new ones at the station during the STS-115 shuttle flight andits 12-A ISS construction mission.


Theastronauts also gathered a set of tools that could be used to remove a pair of gap-fillersjutting out from Discovery's heat-resistant tile covered belly. Shuttleofficials are expected to decide whether that repair, an unprecedented fix, isnecessary, and a report is expected later today.


Noguchiand Robinson also relocated a foot restraint on the exterior of the ISS inpreparation for a spacewalk planned for NASA's STS-121mission aboard Atlantis, the next shuttle flight to follow Discovery's STS-114mission, NASA officials said.
