Shuttle Heat Shield Work This Weekend

Crews working on space shuttle Discovery at NASA’s Kennedy Space Center in Florida will complete testing on the spacecraft’s APU gearboxes Friday before getting into heat shield work during the weekend. The spacecraft is being prepped for the STS-133 mission targeted to launch Nov. 1.

At NASA’s Johnson Space Center, the astronauts will practice procedures in the Neutral Buoyancy Laboratory for the mission’s first spacewalk.
