 Beskrivning :  The launch attempt on 22 March was aborted automatically at T-3 seconds when computers detected an incomplete ignition of the number three Space Shuttle Main Engine. The problem was traced to a leak in the liquid oxygen preburner check valve. All three SSMEs were replaced as a precaution.
 Another launch attempt on 24 April was scrubbed due to a possible faulty reading with one of the inertial measurement units.
 
 The final launch attempt was successful with liftoff at 10:50 am EDT on 26 April 1993.
