Corona 90

  1964-085A


KH-4A Mission 1015 was the 90th flight in the CORONA program. The satellite was launched from Vandenberg by a Thrust Augmented Thor as OPS 3358 and entered a 183 x 410 km x 75 deg orbit. Both SRVs were recovered. The satellite was deactivated from Dec 26 to Dec 28 in the third (and first successful) test of the `zombie' mode, used to protect against weather pattern changes. Imagery included 2 new missile complexes, 8 new launch sites, a new radar site, and coverage of Indonesia, Zaire and Cuba.
