Kosmos 1807

 1986-099A

---

Kosmos-1807 was the last Kobal't launch of the year and had an unusually short lifetime. This seems to have been due to it being a test mission.

TRW's Lightsat facility at Chantilly, Virginia built STEP Mission 4 (P95-A). for the STP Office at the USAF Space and Missile Systems Center. Launch is mid 1997  by Pegasus XL into a 400 km orbit, with onboard propulsion raising the orbit to 600 km. The mission carries STP experiments for studying the atmosphere and ionosphere.

After a perfect launch by the Pegasus the satellite failed to deploy its solar panels or communicate with the ground. The satellite transmitted for a week before falling silent.

Size is 1.52m x 0.91m. Mass is 403 kg.

Soyuz spacecraft 7K-T No. 49 was launched on 1979 Apr 10 and named Soyuz-33. Crew were civilian Energiya astronaut Nikolai Rukavishnikov and Bulgarian astronaut Maj. Georgiy Kakalov (although he was called Georgiy Ivanov in Russian sources.) On final approach to DOS 5 (Salyut-6), at a range of 3 km, an engine burn was aborted due to a malfunction. The rendezvous was abandoned and the crew prepared to return to Earth firing the backup engine. After the planned 3 min 8 sec burn, the engine failed to shut down on schedule, and had to be shut off manually 25s later. The result was a high-g ballistic reentry. The astronauts landed safely 320 km SE of Dzezhkazgan.

The 11F92 7K-L1A (or L1S) No. 3 simplified L1-S spaceship was used as the test payload for the first launch of the mighty N-1 rocket. Planned orbit was 287 x 304 km x 50.6 deg. A fire in one first stage engine led to shutdown of all the engines at an altitude of 14 km. The escape rocket fired and safely returned the L-1S cabin to the ground. The plan was for Blok-G to fire for TLI, Blok-D to perform LOI and TEI, with a two day lunar orbital photography mission.

STS-6 (Challenger)

 1983-026A

---

Challenger was prepared for its first mission for the remainder of the year, and was rolled out to the launch pad at the end of November. The first 20 second flight readiness firing was carried out in Dec 1982. During this firing, a hydrogen leak was detected in the aft compartment. A second firing in January, with extra instrumentation, led to the discovery of cracks in main engine fuel lines. The engines were changed out, and the go-ahead was given for a full-fledged launch attempt.

Challenger took off on its first flight on 1983 Apr 4. The external tank impacted at 28.2S, 80.34E. The TDRS-1 satellite was deployed early on Apr 5. On Apr 6 Challenger made an RCS burn in a rendezvous rehearsal. On Apr 7, the first Shuttle spacewalk took place. At 1740, the astronauts entered the airlock to begin a test of the spacesuits and inspect the payload bay. The airlock was depressurized at around 2105; Musgrave exited at 2121 and Peterson egressed at 2126. The astronauts returned to the airlock at 0053 and the airlock was repressurized after 4 h 17 min.
