7K-L1S/3S Mission to Earth's Moon

Goals: This was the first Soviet attempt to send an orbiter to the Moon using a giant booster intended for the planned piloted mission.

Accomplishments: None. The booster crashed about 50 km from the launch site. The orbiter successfully parachuted to safety 32 to 35 km from the pad.

Key Dates
21 Feb 1969:  Launch
Status: Unsuccessful
Fast Facts
This was the first Soviet effort to test a huge rocket powerful enough to carry humans to the Moon.

Investigators believe a fuel pipe broke shortly after launch.

The fuel leak sparked a fire that ultimately destroyed the rocket and its payload.
