Kosmos 215

 1968-033A


DS-U1-A No. 1 (Kosmos-215) was launched in Apr 1968. It was the first Soviet orbiting astronomical observatory, and carried ultraviolet and X-ray telescopes. It might have preceded the Uhuru satellite in making the first X-ray sky survey, but there was a problem with the aspect information needed to reconstruct the direction the spacecraft was pointing, making it difficult to analyze the data. The satellite also carried photometers for Earth atmospheric profiles, and ocean surface brightness measurements.

Kosmos 1174

 1980-030A


According to Sven Grahn, Kosmos-1174 made three attempts to intercept Kosmos-1171 and was then detonated. Nick Johnson's analysis puts the explosion after the first attempt, implying the second two close passes were coincidental.

Eutelsat 203

 1991-083A


Eutelsat II F-3 provided TV broadcasting services like those of F-2. F-3 was the first Eutelsat satellite to use a US launch vehicle, an Atlas II Centaur. The Centaur delivered it to a mildly supersynchronous orbit.

Voskhod 2 (Diamond)

1965-022A


Spaceship 3KD No. 4 followed the 3KD No. 1 test and just preceded the first US Gemini flight. Crew of 3KD No. 4, named Voskhod-2 after launch, were Pavel Belyaev and Aleksey Leonov, both Air Force cosmonauts. Belyaev was designated Komandir (commander) and Leonov was Vtoroy Pilot (Second Pilot).

On rev 17 the spacecraft failed to orient for retrofire. On Rev 18 they manually oriented the spacecraft but ignited the engine 46 seconds late causing a 2000 km overshoot. They landed in the Siberian forest, and spent a night fending off wolves before the rescue party reached them.
