Gemini 1

  1964-018A


Gemini spacecraft 1 was launched in Apr 1964 on a structural integrity test, carrying instrument pallets in the spacecraft crew couches. The mission was designated GT-1 (Gemini Titan 1). Once in orbit, it remained attached to the Titan second stage and reentered after a few days. It transmitted until 2050 UT on the day of launch.

STS-41-G (Challenger)

 1984-108A


After the 41-C mission, NASA started to prepare Challenger for mission 41-H, but that mission was cancelled shortly afterwards. OV-099's next assignment was 41-G. The STS 41-G mission was devoted to science and earth observation. It was launched on 1984 Oct 5, and its crew was the first to include two women, and a Canadian payload specialist.

ERBS deploy was originally scheduled for orbit 6, and was delayed to orbit 9 after thermal problems with its antenna. After ERBS deploy, the orbit was lowered with 4 burns. Operations with the OAST-3 and LFC payloads were carried out. The crew had problems stowing the SIR-B antenna for the OMS-3 burn, which was delayed until a nudge from the RMS fixed the problem.

The ORS carried 85 kg of hydrazine. The first of 6 ORS hydrazine transfers was carried out on Oct 6. An IMAX camera was also carried. The EVA began at 1542. Sullivan and Leestma entered the payload bay and carried out tests with the ORS refuelling experiment. A ball valve mod kit was installed on the ORS and after the EVA was confirmed to be working. The astronauts practiced stowing the Ku-band antenna manually.

Corona 74

 1963-048A


Mission 9061 (CORONA 74) was the second to last MURAL flight and the last CORONA mission to use the standard (no strapons) Thor Agena D launch vehicle. It was also the first CORONA launched from Point Arguello, as Operation DRY DUNE (Ops 2260). Mass was 1375 kg. Agena burn was 7 sec long to make up for low thrust.

After 5 days, on rev 83, SRV separation was commanded, but did not occur. The USGS Web page reports that the SRV separated from the satellite but remained in orbit; the CORONA program summary says the SRV `did not eject properly'. This curious phrasing suggested that it did eject, but possibly in the wrong direction: however, no separate object was tracked in the NORAD satellite catalog.
