NASA Official Mission Narrative
Mission Name: STS-6 (6)
  CHALLENGER (1)
  Pad 39-A (18)
  6th Shuttle mission
  1st Flight OV-099
  1st Shuttle from MLP-2
  1st Launch Light Weight External Tank  
Crew:
  Paul J. Weitz (2), Commander
  Karol J. Bobko (1), Pilot
  Donald H. Peterson (1), Mission Specialist
  F. Story Musgrave (1), Mission Specialist  
Milestones:
  OPF - July 6, 1982
  VAB - Nov. 23, 1982
  PAD - Nov. 30, 1982  
Payload:
  TDRS-A,CFES(2),MLR/NOSL(1),GAS(x3)  
Mission Objectives:  
Launch:
  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.  
Orbit:
  Altitude: 178nm
  Inclination: 28.5 degrees

  SSME-1: SN-2017
  SSME-2: SN-2015
  SSME-3: SN-2012  
Landing:
  April 9, 1983, 10:53:42 a.m. PST, Runway 22, Edwards Air Force Base, Calif.  Rollout distance 7,180 feet, Rollout time 49 sec. Orbiter returned to KSC April 16, 1983. Landing Weight: 190,330 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.
