Soyuz 33

 1979-029A


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.

Zond 7A

  1969-F05


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.

One debris object was cataloged at the end of the 180-day mission, with epoch 2137 UTC Feb 2. I model a possible deorbit over the Pacific with a 120 m/s burn at 0830 to impact around 0900.
