ESSA 3
1966-087A
ESSA III was the first of a new series of Tiros Operational Satellites, called TOS A before launch. It was the first Tiros satellite to be launched directly to polar orbit from Vandenberg Air Force Base in California. Launch by Delta E from Space Launch Complex 2-East was at 1039 on 1966 Oct 2, with orbit insertion at 1057 into a 1383 x 1493 km x 101.1 deg, 2:30pm sun-synchronous orbit. ESSA III replaced ESSA I as the prime global satellite until 1967 Jun 1 when it was placed on standby. ESSA III transmitted until 1968 Oct 9.

Surveyor 5
1967-084A
Surveyor 5 was the first of an enhanced Surveyor type, the A-21A. It used the SLV-3C launch vehicle with a longer Atlas tank and higher thrust engines. It was launched at 0757:01 on 1967 Sep 8 by Atlas Centaur from Kennedy and rolled to an azimuth of 79.52 deg. The Centaur completed its second burn at 0816:27. A course correction was made on Sep 9 as planned, but a helium pressure valve failed to close properly after the firing. As a result, three extra course corrections were made to try and reseat the valve. Two more burns readjusted the velocity and aim point. A new retro profile had to be used, with a low retro burnout altitude of 1.4 km instead of 11 km. The retro was fired at 45 km altitude instead of 83 km, 12 sec later than usual. Landing was at 0046:42 on Sep 11 at 1.41N 23.18E (TR-32-1246).
