1975-052A
Nimbus 6 carried several important experiments, including the first Earth Radiation Budget experiment and a pioneering experiment in satellite data relay and tracking, using the ATS 6 satellite. This experiment was a precursor to the use of TDRS satellites in the 1990s to relay data to Earth from the Hubble Space Telescope and other spacecraft. Launch of Nimbus 6 was at 0812 on 1975 Jun 12 using a Delta model 2910 from Vandenberg. The Delta separated at 0918 leaving Nimbus in a 1092 x 1104 km x 100.0 deg orbit, and the satellite began regular operations on Jul 14. It was decommissioned on 1983 Sep 30.
