1990-002A
The STS-32R mission was launched on 1990 Jan 9. The Syncom IV-5 satellite was deployed on Jan 10. From Jan 9 to Jan 12 the slow rendezvous with LDEF was carried out, with the TI (Terminal phase Initiation) burn at 1216 on Jan 12. Radar issues during the approach led to an NCC burn 1m/s too high and the TI burn point was off by 9 km, leading to final approach at a higher relative velocity than expected. Nevertheless, the crew were able to brake Columbia to a stop on the -R-bar above LDEF at the targeted time.
Dunbar grappled LDEF with the RMS arm at 1516. LDEF was kept on the arm while a photo survey of the satellite was made. At 1910 the survey was complete and LDEF was moved down into the payload bay. It was finally berthed at 2040. On Jan 13 Marsha Ivins carried out tests on the RMS arm. DTO 636 involved testing the `direct drive' mode. The RMS was also used to inspect a tile on one of the elevons. The next day David Low used the arm to survey the port wing, and on Jan 15 Dunbar completed the tests with a survey of the OMS pod and tail.
The landing was scheduled for Jan 19, but was postponed due to fog at Edwards. The OMS engines ignited at 0830 on Jan 20 for their longest burn ever, a 149 m/s deorbit burn with an out-of-plane component of 51 degrees. Columbia touched down at Edwards on concrete runway 22 at 0935.
