Kosmos 1510
1983-115A
Kosmos-1510 went to a new inclination of 73.6 deg. The launch profile for the 73 deg orbit used lower altitudes for second stage separation and gave final orbit insertion some 8 minutes later.

Venera 4
1967-058A
The first in the new series was V-67 No. 310. It was launched on 1967 Jun 12 and named Venera-4. A course correction on Jul 27 corrected the initial miss distance of 160000 km. The main bus separated from the Spuskaemiy Apparat (SA) prior to entry. At an altitude of 55 km the parachutes were deployed and the instruments were turned on. The Venera-4 SA was apparently destroyed at an altitude of 27 km and impacted near latitude +19, longitude 38. The extrapolated surface conditions were temperature 500C, pressure 75 bar.

GOES-G
1986-F04
GOES G was launched at 2218 on 1986 May 3 by a Delta 3914 from Launch Complex 17A at Cape Canaveral. Only a minute into the flight, a short circuit from a chafing wire caused a premature main engine cutoff on the ELT Thor stage. The nose fairing broke up due to aerodynamic pressure, and the range safety officer destroyed the rocket at T+90 sec.

Explorer 6
1959-004
The S-002 satellite (Explorer 6) carried a number of experiments to study the magnetosphere. It was the STL Able-3 probe, left over from the pre-NASA program as a testbed for the Able-4 Venus probe (later Pioneer 5). Able-3 was launched by a Thor Able III rocket from Cape Canaveral at 1423 on 1959 Aug 7 at an azimuth of 48 deg. Thor 134 used AJ10-101A serial P SA-3-1 stage 2 and X248-A4 serial 52 for stage 3. The S-2 payload was S/N 003 and was a 0.74m sphere with four paddles and a mass of 40 kg. Stage 3 was 25 kg empty with 210 kg prop.
One of the satellite’s solar paddles did not lock open. A two-part separation band was jettisoned to separate the Altair stage; the band parts were not cataloged. S-2 transmitted until Oct 6, and reentered sometime around 1961 Jul. The last available orbital data are on 1959 Sep 29. It was the first satellite to be significantly affected by lunisolar perturbations, and its flight caused renewed theoretical interest in these effects.
Explorer VI carried a 22N thrust solid ARC 1KS420 kick motor, S/N S6, to trim the orbit if needed, but the Thor Able performed well and the motor was not fired.
Some sources call the payload 1959 Delta 2 and the rocket Delta 1, but the current choice seems to be the other way round.
The Able-3 test vehicle was also used to test out systems planned for Able-4, including the third stage and the tracking systems.
