1973-086A
NOAA 3 (ITOS F) was launched at 1702 on 1973 Nov 6 by Delta from Vandenberg. The Delta stage ignited at 1706 and cutoff at 1711 to place itself in elliptical transfer orbit. At 1759 it reignited to circularize the orbit, and separated at 1806, leaving NOAA 3 in a 116.1 min, 1500 x 1509 km x 102.1 deg orbit. Delta test burns at 1818 and 1838 left the Delta in a 1503 x 1512 km orbit. NOAA 3 deployed its solar panels on the 6th orbit and began its NASA checkout phase. It was delivered to NOAA later in the month. On 1976 Aug 31 NOAA 3 was decommissioned and replaced by NOAA 5.
