STS-112 Mission Specialist Sandra Magnus is happy to return to KSC to prepare for launch. She will be making her first Shuttle flight. STS-112, aboard Space Shuttle Atlantis, is the 15th assembly mission to the International Space Station. Atlantis will be carrying the S1 Integrated Truss Structure, the first starboard truss segment, to be attached to the central truss segment, S0, and the Crew and Equipment Translation Aid (CETA) Cart A. The CETA is the first of two human-powered carts that will ride along the ISS railway, providing mobile work platforms for future spacewalking astronauts. The 11-day mission includes three spacewalks. Launch is scheduled for Oct. 2 between 2 and 6 p.m.
