STS-6 

The mission of the STS-6

This was the first Challenger mission, and was the first time a new lightweight external tank and lightweight SRB[?] casings. Launch was delayed several times due to a hydrogen leak in Engine 1, along with fuel line cracks in the other two engines. Engine 1 was replaced, and the other two were fixed.

STS-6 launched the first Tracking and Data Relay Satellite[?] (TDRS). Launch was not without its problems; The TDRS's two-stage booster rocket called the Interim Upper Stage (IUS), shut down early, which placed the satellite into a low elliptical orbit. Fortunately, the satellite contained extra propellant beyond what was needed, and over the next several months the thrusters were used to bring it into a geosynchronous orbit.

STS-6 also marked the first space walk for the shuttle program. The new space suits were designed for the shuttle. The EVA was preformed by the two mission specialists on April 7 and its objective was to perform various tests in the payload bay[?]. Their space walk lasted for 4 hours, 17 minutes.

Other STS-6 cargo included three GAS[?] canisters and continuation of the Monodisperse Latex Reactor and the Continuous Flow Electrophoresis experiments.

McGinnis. . . . Yes, he is here. Yes. . . . rather peremptory. . . . All right, sir, I shall tell.
