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.
