Description:
LANDSAT-4 (formerly LANDSAT-D) was launched successfully at 1:59 p.m. EDT on July 16, 1982, from Vandenberg Air Force Base. The Delta 3920 launch vehicle performed flawlessly and placed the satellite into the planned three sigma low orbit of 694 km. The lower orbit was selected to eliminate a retrograde maneuver for the orbit adjust burns necessary to place the satellite into its planned operational 16-day repeat track at 705 km. Spacecraft separation and the initiation of solar array depolyment occurred, over the Indian Ocean tracking station. Spacecraft attitude rates at separation were low, allowing the Earth sensor to immediately acquire the Earth with the momentum wheels and without use of the propulsion system. All systems activated as of noon on July 18, 1982, are performing well with no significant discrepancies reported.
