NOAA B

 1980-043A


NOAA B was launched at 1053 on 1980 May 29 by an Atlas F from SLC3W at Vandenberg. The Atlas booster engine thrust was too low, and the Atlas main engine sustainer burned for an extra 54s in an attempt to compensate. However at 1100 the Atlas separated prematurely from the NOAA satellite - but since it was still thrusting the NOAA remained attached! At 1103 the Star 37S motor fired but attitude control propellant was almost depleted and the orbit acheived was 102.1 min, 264 x 1445 x 92.2 deg, far from the desired circular sun-synchronous orbit. On May 30 NOAA B was powered down and decommissioned; it reentered on 1981 May 3.

Gambit-3 29

 1970-090A


KH-8 29 (GAMBIT 4329) was launched on 1970 Oct 23 by Titan IIIB Agena D from Vandenberg on a 19 day flight. Its mission probably included imaging of missile silos for the R-36 (SS-9) missile. Major orbit raising burns were carried out on Oct 24 and around Nov 5.

Explorer 39

 1968-066A


The AD-C (Air Density Explorer C, Explorer XXXIX) satellite was launched from Vandenberg on 1968 Aug 8. The Scout delivered it into a 670 x 2538 km x 80.7 deg orbit, together with Explorer XL. Explorer XXXIX's beacon transmitted until 1971 Jun; it was reactivated on 1976 Feb 20. The satellite reentered on 1981 Jun 22.

The Injun satellite had a mass of 63 kg not counting the ADE. The ADE hardware had a total mass of 16 kg, 9.4 kg of which was the 3.66-m dia balloon satellite, made of Al foil and polyethylene-terephthalate plastic film. Attached to the balloon surface was a battery unit, a solar cell package, and a transmitter. The Al foil sphere had a small 0.01m equatorial gap turning the Al into an antenna.

The AD deployer consists of a container, a spearation mechanism, ejection bellows and an inflation bottle, for a total mass of 7 kg; this remained with the Injun satellite, giving it an orbital mass of 70 kg.

The AD/Injun pair was launched near solar max, to complement the earlier IQSY mission.

The Scout E-section payload adapter had a mass of 4.5 kg.

Debris detected in orbit had a slower decay rate than the balloon, and may be associated with Injun. Debris cataloged starting in 1994 was at an altitude consistent with some of the rest of the debris, suggesting that it separated from Injun in the 1960s or 1970s.
