SWAS
1998-071A
A NASA-GSFC SMEX mission, the Submillimeter Wave Astronomy Satellite was to be the first in that waveband. Originally scheduled for a 1995 launch, SWAS slipped to late 1998 because of Pegasus problems. Principal investigator was Gary Melnick of SAO, which operated the mission science center.
The 0.71m primary antenna was used to study molecular clouds.
600x600 km x 70 deg orbit. Launch by Pegasus XL from VAFB.
Spacecraft was a wasp-shaped double cone with two solar panels, plus the instrument module with the primary mirror, three radiator horns, and a magnetometer. Size 1.65 l 0.97 d, mass is 282 kg.
m1/m2 = 484/1254
The last science observations were taken on 2004 Jul 23; GSFC will use it as a software testbed until 2005 Sep.

Tance 1
2003-061A
\imps{2.5}{images/03061}
Launch of TC-1
\imps{2.5}{images/03061A}
The TC-1 satellite
Tan Ce (Explorer) 1, or Double Star DSP-E, Chinese/ESA magnetospheric satellites, to supplement the Cluster system and using backup European Cluster instruments. Equatorial DSP-E 550 x 66970 x 28.5 planned orbit. Launch Dec 2003 and Apr 2004 by CZ-2C/SM (or CTS). CTS top stage derived from SD. Places 1400 kg in SSO. Has FG-47 solid motor.
Spin-stabilized satellites, 350 kg built by CATC's Space Tech Inst. Spacecraft is a 2.1m dia 1.4m high spin stabilized (15 rpm) cylinder, with overall size 4.0m high 8.3m span. Used a direct ascent orbit with all three stages burning without coast phase, giving perigee around 23 deg N.
The PKM was described in a paper at IAC 2004. It is 1.4m dia. Mass is 2929 kg full, 2620 kg prop, 309 kg dry. Total impulse is 7477 kNs and Isp is 291.0s (Ve=2.854 km/s). For a TC-1 mass of 350 kg, the rocket equation gives a dV of 2.854 ln ( 3279 / 659 ) = 4.579 km/s.
Another source gives SM? 2.7m dia 1.5m long, 125 + 50 kg prop, 10.7 kN, Ve 2804 SMA: 2.7m dia 0.9m long, 21.7 kg propellant, 10.4 kN, Ve 2804 SM: 1.4m dia 2.3m long 2620 kg prop, 101 kN Ve 2863
Apogee was higher than planned.

Orion 1
1994-079A
Orion 1 was a Eurostar 2000 class satellite built for Orion Network Systems Inc, Rockville MD by British Aerospace Space Systems Ltd. It provided commercial transatlantic communication services.
This was the first comsat to use a very high apogee supersynchronous transfer. LEOP control was from MMS SCC,Stevenage. ORION had a ground station at Mt Jackson, Virginia. The satellite was reportedly registered with the UN by the UK (although the document does not appear to be in the public archive). It was also registered by the US in ST/SG/SER.E/288.
In Nov 1999 Loral Orion renamed the satellite Telstar 11. Loral Orion then became Loral Skynet.
