This was the Soviet Union's third and final attempt in 1962 to send a spacecraft to Mars as an engineering testbed. Unlike the other two missions, this one was designed to crash into Mars.


None. A timer malfunction shut down the main engine too soon, leaving the spacecraft stranded in Earth orbit. It eventually burned up in Earth's atmosphere.

In Depth

This was the third and last of the Soviet second-generation Mars attempts in 1962 and also the only lander in the series.

During the trans-Mars injection firing of the Blok L stage, the main engine (the S1.5400A1) prematurely shut down after 33 seconds due to a malfunction in the programmed timer for the stage. The problem was later traced to excessive vibrations of the second stage during liftoff. These vibrations evidently also jarred loose a pyrotechnic igniter from its support, preventing the Blok L upper stage from firing.

The spacecraft remained stranded in orbit and re-entered Earth's atmosphere. The spacecraft had been intended to fly by Mars on June 21, 1963.
