Skylab 4

  1973-090A



    Skylab SL-3 Crew

  • Commander Gerald Carr, LtCol USMC

  • Science Pilot Edward Gibson, Ph.D., NASA

  • Pilot William Pogue, LtCol USAF

Apollo CSM 118 was stood down from its role as Skylab Rescue on 1973 Sep 9 (see SL-3). Launch as Skylab SL-4 was at 1401:23 on 1973 Nov 16. It reached a 154 x 224 km x 50.0 deg Earth orbit at 1411:10. The S-IVB stage separated at 1426:22.

The rendezvous burns began at 1624 with a 2-second SPS firing. By 1958 UT the ship was in a 412 x 421 km orbit, and rendezvous was complete by 2126. SL-4 docked at the axial port on the third attempt at 2202. The hatches were opened at 1430 on Nov 17. The CSM was powered down on Dec 4. Meanwhile, on 3 Dec the SA-209 rocket arrived at pad 39B with Apollo CSM 119 on top. CSM 119 would be Skylab Rescue with the Brand-Lind crew if a rescue were needed for this mission.

CSM 118 was powered up again on 1974 Feb 6. The crew had entered the spaceship by 0615 on Feb 8 and installed the docking probe at 0630. A test burn with the RCS thrusters was made at 0815. Undocking came at 1034 and was followed by a flyaround of Skylab. At 1100:07 an RCS sep burn changed the orbit from 433 x 456 km to 430 x 456 km. An SPS orbit shaping burn at 1132:54 lowered the orbit to 168 x 430 km. The SPS fired again at 1435:59 for the deorbit burn. The SM separated and the CM reentered, splashing down in the Pacific at 1516:55 on 1974 Feb 8. Landing was at 119 48 12W 31 18 12 N It was recovered by the USS New Orleans.
