Turksat 1C

 1996-040B


Turksat 1C was lauched by Ariane for Aerospatiale, which delivered it on orbit to Turk Telecom. Launch mass was 1743 kg, BOL mass 1078 kg and dry mass 789 kg. The satellite is 1.64 x 1.46 m x 2.20 m with a 22.20 m span. It was built by Aerospatiale-Cannes. The satellite was launched in the lower Ariane position, underneath the SMS (Stretched Mini Spelda) structure. It provides services to Turkey. Initial test position is 31.3E, then service position is 42E.

ST-5

 2006-008A


Each Nanosat Constellation Trailblazer is 25 kg, 0.52m dia 0.48 high oct prism with an extendable boom for 1.0m? span. Three satellites on a single launch to 300 x 4500 km x 97 deg on Pegasus XL from Vandenberg. Built by GSFC. Will study magnetosphere; spacecraft highly magnetically clean to allow short mag booms.

Skynet 4D

 1998-002A


Skynet 4D is the first of three replacement Skynet 4 Stage 2 satellites. It will be launched 1998 by Delta. It is built by Matra Marconi Space/Stevenage. It still uses the old ECS bus, but has a steerable high power SHF spot beam and widebeam antennae.

During launch, the Delta second stage suffered two jolts, one during the second burn and one 15 s into the depletion burn, which caused the nearly empty stage to tumble.

The Skynet 4D was transferred from MMS to MoD on 1998 May 20.

In early 2003 4D was moved from the Atlantic position to support troops in the Middle East.

UARS

 1991-063B


The Upper Atmosphere Research Satellite, built by General Electric, used the Fairchild MMS bus (like Landsat D). It had a total mass of 6526 kg at deployment per the SODB; 6540 kg per the press kit. The satellite was launched on STS-48. The RMS grappled the satellite at 2300 on Sep 14, and it was finally deployed at 0423:02 on Sep 15 into a 563 x 574 km x 57.0 deg orbit. Orbit raising burns were made at 1035 on Sep 17 and 1036 on Sep 18.
