(ATO) after SSME No. 1 shut down early at T+ 5 minutes, 43.4 seconds due to faulty
sensor, OMS ignited for 106 seconds to lighten the vehicle to achieve orbit, SSME No. 2
and 3 also burned for an extra 1 minute, 26 seconds. First launch attempt scrubbed on
12 July when No. 2 engine cutoff at T-3 seconds at 4:30 pm EDT, due to faulty sensor.
