Galaxy 13

 2003-044A


Galaxy XIII/Horizons-1 will be launched by Zenit 3SL in 2003. At 127W, the BSS 601HP satellite will cover N and Central America. Its Ku-band Horizons-1 payload will be jointly owned by Panamsat and JSAT and will use a Hawaii relay station to deliver digital services between the USA and Asia. The C-band Galaxy XIII will replace Galaxy IX and support the US domestic cable distribution network.

Tempo 2

 1997-011A


The Tempo satellites were owned by TCI Satellite Entertainment Inc. (TSAT), a subsidiary of TCI (Telecommunications Inc) of Littleton, Colorado, and provided high power direct TV broadcasting for the United States. It uses the SS/Loral FS-1300 bus. 

The launch of TEMPO 1 was delayed; A last minute FCC ruling that it could not use a Canadian orbital slot and frequencies caused the payload to be reduced from 27 to 11 transponders. Once regulatory problems were resolved, the processing flow for TEMPO 2 was in better shape to allow launch and so it went first. TEMPO 2 launch mass was 3558 kg. It will use the 119W slot.

A month after launch, Tempo 2 suffered a power failure during a solar storm, leaving it operating at 85 percent power. Tempo 2 had the first GaAs arrays on a high power comsat. Loral reported later that solar arrays wired at more than 60V were prone to electrical discharges and short circuits during moderate solar activity.

Tempo 2 became the property of DirecTV/El Segundo in 1999. It was renamed DirecTV-6.

Unity

 1998-069F


Boeing/Huntsville makes Node 1, the first docking node for ISS. Later Nodes will be built by Alenia. Node 1 was named Unity in 1998. Unity is 5.2m long and 4.4m in diameter. The CBM is 2.1m in diameter.

Note 1 has four stowage bays.

Per the press kit, Unity/PMA1/2 launch mass was about 11600 kg. If each PMA is 1160 kg, then Unity is 9280 kg. Other data gives a mass of 9946 kg, which may represent data after outfitting. It is not clear which figures include the mass of equipment added during the STS-88 EVAs.

Per the STS data summaries, deployed mass for the mission was 12152 kg, with 152 kg for returned (presumably FGB) cargo. Accounting for 128 kg in the subsatellites, that leaves 12024 kg for the deployed mass of Unity/PMAs, or 9704 kg for Unity alone. I will adopt the latter. If this includes about 190 kg of EVA-added hardware then the mass drops to 9514 kg. We can add 234 kg of internally transferred cargo to make recover the 9280 kg estimate for Unity alone.
