Magsat
1979-094A
Applications Explorer Mission C was the Global Magnetic Survey Mission, or Magsat. The main spacecraft was a cylinder with four solar arrays; a special optical system was used at the end of the magnetometer boom to correlate magnetometer position with the star tracker on the main bus. Magsat was launched on 1979 Oct 30 at 1416 by Scout G-1 from Vandenberg. At 1426 it was inserted into a 93.8 min, 355 x 562 km x 96.8 deg orbit. Magsat transmitted until it reentered on 1980 Jun 11 at 1930 over the Norwegian Sea.
