April 4, 1983, 1:30:00 p.m. EST. Launch set for Jan. 20 postponed due to hydrogen leak into number one main engine aft compartment discovered during 20 second Flight Readiness Firing (FRF) Dec. 18, 1982. Cracks in number one main engine confirmed to be cause of leak during second FRF performed Jan. 25, 1983. All three main engines removed while Shuttle was on the pad and fuel line cracks repaired. Main engines two and three reinstalled following extensive failure analysis and testing. Number one main engine replaced. Additional delay caused by contamination to Tracking and Data Relay Satellite-1 (TDRS-1) during a severe storm. Launch on April 4 proceeded as scheduled. Launch Weight: 256,744 lbs.

Mission Highlights:

Primary payload was first Tracking and Data Relay Satellite-1
(TDRS-1). Malfunction of Inertial Upper Stage booster resulted in
placement of spacecraft into improper but stable orbit. Additional
propellant aboard satellite used over next several months gradually
place TDRS-1 into properly circularized orbit. First space walk
of Shuttle program performed by Peterson and Musgrave, lasting
about four hours, 17 minutes. Other payloads: Continuous Flow
Electrophoresis System (CFES), Monodisperse Latex Reactor (MLR)
(MLR), Radiation Monitoring Experiment (RME). Night/Day Optical
Survey of Lightning (NOSL), and three Get Away Special canisters.
Mission used first lightweight external tank and lightweight
rocket booster casings.
