Goals

Like Luna 3 and its unsuccessful follow-up mission, this Soviet spacecraft was designed to photograph the far side of the Moon and gather data on interplanetary space.

Accomplishments

None. The launch vehicle broke apart 10 seconds after launch, scattering debris around the launch site. Explosions shattered many nearby windows.

In Depth

This was the last of the "first-generation" Soviet probes to the Moon. Like its immediate predecessor, it was designed to photograph the far side of the Moon.

Unfortunately, the probe never left Earth's atmosphere. Instead, immediately after launch, at T+10 seconds, the launch vehicle began to fall apart. As each strap-on fell away, parts of the booster landed separately over a large area near the launch site. Thundering explosions broke windows in many nearby buildings.
