E-6 No. 12 (Luna-8) was another failure; this time the retro burn came too late, with the same result - a destructive impact on the lunar surface. The airbags did not inflate properly, tumbling the spacecraft.
The launch used a lower inclination 51.8 deg parking orbit, allowing a larger launch mass of 1552 kg. This may have been the first E-6 flight with the 11S59 core stage.
