Discovery Astronauts Set For SpacewalkRepair

 

3 August 2005; 4:17 a.m. EDT

 

HOUSTON - Two astronautsare preparing to step outside the space shuttle Discovery to perform an on-orbitrepair to the orbiter's heat shield.

 

 

STS-114spacewalkers Soichi Noguchi and Stephen Robinson arein the shuttle's airlock, clad in U.S.-built spacesuits, and set to make theirthird and final extravehicular activity (EVA) of Discovery's flight.

 

 

Aboutthree hours and 20 minutes into today's spacewalk, Robinson will stand atop therobotic arm aboard the International Space Station (ISS), where Discovery iscurrently docked, and be maneuvered underneath the shuttle to pluck two fillerstrips jutting out form the spacecraft's tile-covered heat shield. Noguchi willobserve the repair from a vantage point aboard the ISS.

 

 

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.
