Key Dates

In Depth

This spacecraft, a 7K-L1 type, was the first of a series of spacecraft that the Soviets tried to send on circumlunar missions as part of a larger project to send cosmonauts around the Moon.

The program, which was officially approved in October 1965, was set off by two technological flights in Earth orbit in March and April 1967. The 7K-L1 spacecraft was a stripped-down version of the larger 7K-OK Soyuz spacecraft intended for Earth-orbital operations.

During this launch, one of the six first-stage engines failed to fire because of blockage of a propellant line, and the launch vehicle was destroyed at T+97.4 seconds.
