This was another Soviet attempt to safely land a spacecraft on the Moon. The lander was equipped with cameras and a radiation detector.
None. A malfunction stranded the spacecraft in Earth orbit. It burned up in Earth's atmosphere five days after launch.
Yet another Soviet attempt to soft-land a Ye-6 probe on the lunar surface ended in failure when the Blok L upper stage failed to fire for the translunar injection burn. Instead, the spacecraft remained stranded in Earth orbit.
A later investigation indicated that there had been a short circuit in an inverter within the I-100 guidance system of the spacecraft (which also controlled the Blok L stage) preventing engine ignition. The spacecraft's orbit decayed five days later.
