Spot 2

 1990-005A


The second SPOT used the SPOT Mk 1 bus, and was launched on 1990 Jan 22 on an Ariane into an 800 km orbit. The orbit was raised to 825 km by Jan 30 and the satellite was declared operational and turned over to the Spot Image operating team on Mar 23. In addition to the CCD imagers, SPOT 2 carried the DORIS experiment to allow accurate orbit determination.

In Jul 1997 a collision avoidance burn was made to avoid a 400m flyby of object 5061, increasing orbital height by 400m for a day.

AMC-10

 2004-003A


SES Americom satellite using A2100 bus for digital cable delivery. Launch mass 2315 kg, 907 kg dry.

The satellite would replace Satcom C-4 at 135W. AMC-7 at 137W served as an in-orbit backup.

The launch used a new profile, in which the second Centaur burn, carried out at the equator, lowered inclination to only 12 degrees, decreasing the amount of fuel needed for the satellite's apogee burn.

STS-92 (Discovery)

 2000-062A


Discovery remained in the VAB until Atlantis launched because of concerns about having two stacks on the pads during hurricane season.

Launch mass was 115125 kg. Landing mass was 92739 kg (press kit values). Mass at docking is 111023 kg. At Oct 16, docked mass is 171784 kg. ISS mass is 69445 kg? STS mass is 102339 kg? At Oct 21 mass is 97911 kg.

Cargo transfer of 9978 kg including 8324 kg Z1 and 1156 kg PMA-3, 498 kg other. That 498 kg includes internal cargo transfer; it may also include the ETSDs (188 kg?) and the DDCUs (116 kg), or these may be included in the Z1 mass. For the time being I will assume it is internal cargo. SODB says deployed is 9978, retrieved 133. Non-deployed bay cargo of 2122 kg includes the 300? kg ICBC, the 1400 kg pallet, about 160 kg of DDCU carriers, and 262 kg remaining - which may be extra pallet-attached hardware.

The SGANT deployed is 374 kg per a prelaunch (DAC9) analysis. I have 88 kg for antenna, 34 kg for SGTRC, leaving 252 kg for the boom and attach hardware. The total of Z1 ORUs is then 2267 kg; if Z1 is 8324 kg total, then it is 6057 bare. Another source gave 8765 kg for Z1 mass which would require the other figures to be adjusted accordingly.

On Oct 5, a concern about the ET explosive bolts caused a scrub. Weather forbade on Oct 9 attempt. On Oct 10 a small loose pin lying on the ET noticed by the ice team caused a scrub.

The Ku-band system failed, taking out live TV and requiring the crew to use the TCS laser rangefinders and optical star trackers for navigation during rendezvous.

On Oct 14, a power spike took out the keel camera and the SVS during RMS uncradle, but backup systems restored the SVS.

In the first EVA, the Z1-to-Unity umbilicals are connected. The SASA (S-band) is moved from the DDCU install location to a deployed location. The SGANT (Ku-band) is moved to a new location on Z1 and deployed.

On EVA-4, Wisoff and Lopez-Alegria finished up the work. They cycled the Z1/P6 latch, deploy an ammonia coolant attachment panel, and move the Z1 keel pin to a storage location. They then tested the SAFER backpacks, making semi-free flights with a slack tether.

After two waveoffs, landing was at RW22 EAFB for the first Edwards landing in 4 years.

GOES 5

 1981-049A


Geostationary Operational Environmental Satellite 05 (GOES E) was launched by Delta 3914 from Cape Canaveral LC17A at 2229 on 1981 May 22. At 2252 the Star 37E third stage left GOES 5 in a 192 x 49768 km x 26.6 deg transfer orbit. The next day the TE-M-616 apogee motor circularized the orbit to 33840 x 49667 km x 0 deg. GOES 5 reached geostationary orbit at 85 deg W on Jun 5 for checkout, and was then moved to the GOES E position, replacing SMS 2 on Aug 5. The VAS failed on 1984 Jul 29 but GOES 5 was kept at the GOES E position for data relay work with the DCS.

TD-1A

  1972-014A


The TD-1A satellite was ESRO's first astronomy satellite, the TD standing for Thor Delta (the launch vehicle). It was built by Matra and controlled from the ESOC facility, TD-1A made the first ultraviolet stellar sky survey. The early loss of the satellite’s tape recorders meant that extra tracking stations were pressed into service.

TDRS-3

 1988-091B


The TDRS C payload was named TDRS 3 on reaching orbit. TDRS 3 was carried into space on the first `return to flight' mission, STS-26R. Discovery was launched on 1988 Sep 29 and the TDRS/IUS was deployed at The first IUS burn, at 2250 on Sep 29, left TDRS in a 632.98 min, 287 x 35797 km x 26.71 deg orbit. The second burn, at 0406 on Sep 30, put it in a 1433.48 min, 35673 x 35798 km x 2.3 deg circular orbit. By Oct 5 it had reached the TDRS WEST position at 171 W. In around 1992 it was moved to 62W as TDRS SPARE, but in 1994 it was reassigned to move back to the TDRS WEST position.
