1967-114A
TOS D, the third operational APT satellite, was renamed ESSA VI after its successful launch on 1967 Nov 10 frm Vandenberg. The Delta E1 launch vehicle put ESSA VI in a 1410 x 1488 km x 102.1 deg orbit and it was declared operational on Nov 22. Two years later it was noted that the vidicon cameras had degraded and that the satellite had drifted out of sun-synchronous orbit. ESSA VI was decommissioned on 1969 Dec 12.
