Explorer 21
1964-060A
IMP B (Interplanetary Monitoring Platform B) was launched on 1964 Oct 4, 0345 by Delta C from Cape Kennedy. The Altair stage again did not burn fully and the satellite was left after orbit insertion at 0352 in a 190 x 95595 km x 33.5 deg orbit instead of the intended 200 x 200000 km, representing a 167.73 m/s underburn. Interplanetary Monitoring Platform 2, which was also given the Explorer designation Explorer 21), operated until 1965 Oct 13. Initially the orbit was toward the Sun along the Earth-Sun line (local noon) and migrated to later local times at 1 degree per day.

Kosmos 22
1963-045A
The first 11F69 satellite, Zenit-4 No. 1, was launched in Nov 1963 as Kosmos-22. It used the new 11A57 launch vehicle, later named Voskhod, which was the interplanetary 8K78 without the Blok-L fourth stage. The test flight lasted 6 days, in an orbit similar to that used by the Zenit-2 satellites. The Zenit-4 probably carried higher resolution cameras than the Zenit-2.

The second Leasat, Leasat 1 or Syncom IV F1, reached orbit on Shuttle mission 51-A. It was stationed over the eastern Atlantic.

STS-32 (Columbia)
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.
