Summary

Zond 4 launched on a Soviet Space Program Proton / UR-500 K/D from 81/23 (81L), Baikonur Cosmodrome, Republic of Kazakhstan on March 2, 1968. It was Soviet Space Program's 296th launch, 7th this year and humanity's 802nd orbital launch attempt. It was the 5th Proton / UR-500 K/D flight and the 1st this year. The payload was bound for High Earth Orbit (HEO). Zond-4, one of 4 catalogued objects, reached a 199 × 283 km orbit inclined 51.6°. The spacecraft was Soyuz 7K-L1 No.6 (Soyuz 7K-L1 #6). 4 objects from this launch are catalogued, one of them a payload.

Spacecraft

Soyuz 7K-L1 No.6 (Soyuz 7K-L1 #6)

The Soyuz 7K-L1 "Zond" spacecraft was designed to launch men from the Earth to circle the Moon without going into lunar orbit in the context of the Soviet crewed Moon-flyby program in the Moon race. It was based on the Soyuz 7K-OK.

  • Destination: Low Earth Orbit
  • Mission length: 4 days 5 hours

The Soyuz 7K-L1 spacecraft was intentionally blown up when a failure of the re-entry guidance system prevented it from generatic lift and bouncing off the atmosphere, initiating a ballistic re-entry outside Soviet soil.

About this launch

Zond 4 was the first Soyuz 7K-L1 to reach a deep-space trajectory, sent to an apogee of about 400,000 km in the direction opposite the Moon to test the capsule and its Argon 11 computer. A guidance failure prevented the planned skip reentry and the capsule was blown up by its destruct system over the Gulf of Guinea.
