STS-4 (Columbia)

 1982-065A

---

STS-4 was the fourth and last Orbital Test Flight mission. Launch of STS-4 was at 1500:00 on 1982 Jun 27. After four OMS burns, Columbia entered a 295 x 303 km x 28.5 deg orbit. The crew ran into a major payload problem when the aperture door on the CIRRIS telescope failed to deploy. On Jun 29, it was time for more tests of the RMS. The RMS grappled the Induced Environment Contamination Monitor and moved it around the bay to make contamination measurements. The next two days saw more tests of the payload bay doors and of the RCS and OMS engines. At 1100 on Jul 2, Mattingly tested out the new EVA spacesuit. Later that day, more RCS burns were used to test the dynamics of the RMS arm. Columbia landed at Edwards AFB on Jul 4.
