Lanyard 3

 1963-032A


On the third and last LANYARD flight, mission 8003 (CORONA program flight 68), the only photos returned from the KH-6 were out of focus due to thermal design problems. This third flight came a few weeks after the test flight of the USAF's GAMBIT high resolution satellite, and the CIA program was cancelled in favour of the new Air Force system.

LANYARD/Agena orbital mass was 1604 kg. The Itek list records this flight as Mission 2006, but this is almost certainly an error. NORAD tracked a debris object, 1963-32B, in a 172 x 418 x 74.9 deg orbit (SATCAT); it reentered Aug 10. It may have been the camera door.

The index camera malfunctioned immediately and the main camera failed on orbit 23.

An NRO memo reports that the mission imaged an SR-71 Blackbird flying over Edwards.

Nimbus 6

  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.
