Soyuz 27

Soyuz-27 (7K-T No. 44) was launched on 1978 Jan 10 and docked with the front port of Salyut-6 on Jan 11. Crew Vladimir Dzhanibekov and Oleg Makarov transferred to Soyuz-26, leaving the fresh craft for the EO-1 crew of Romanenko and Grechko.

Satcom 1R

 1983-030A


The RCA F payload, an Advanced Satcom bus built by RCA Astro Electronics, was launched in 1983 to replace Satcom 1 and was named Satcom 1R on reaching orbit. In 1988 the satellite became the property of GE Americom.

The post launch MOR records the apogee burn time as Apr 14 1430 EST (well, it says EDT but that is an obvious error). The final transfer orbit TLE from Apr 13 puts the spacecraft at 140W at that time at 7th apogee, while the first post-burn TLEs from Apr 15 put it at 90W. Perhaps a further burn occurred prior to the Apr 15 data - those TLEs put the vehicle at 103-107W on Apr 15-16. More likely, however is that the MOR document, despite its almost contemporary nature (dated 1984 Jul 26) and official provenance, is in error and the burn was delayed to 9th apogee on Apr 15 at 1700 UTC.

Macsat 1/2

 1990-043A


DARPA's MACSATs (Multiple Access Comsats) were followons to the GLOMR payloads and demonstrated tactical communications relays. The 70kg satellites, built by DSI, were launched together on a single Scout G-1 from Vandenberg in May 1990. They reached a 612 x 768 km orbit comparedwith the planned 740 km circular one. The MACSATs were 0.61m in diameter and 0.36m high, with a 6.1m gravity gradient boom.

The Master Control Station was in McLean, Virginia.

Macsat 2 was intended for experimental use but was pressed into service to support the US Marine Corps during the Persian Gulf conflict. The 68kg UHF communications store-forward satellite was built by DSI for DARPA.
