This was the second Soviet attempt to accomplish a soft-landing on the Moon.

This time, the spacecraft failed to reach Earth orbit. Following separation of the second stage, the booster lost attitude control and deposited its third and fourth stages in the Pacific Ocean near Midway Island.

Later investigation indicated that the I-100 guidance system provided incorrect information to the booster's trajectory control system.
