Zond L1S-1 was a Zond capsule to be placed into orbit around the Moon by the first launch of the N1, a Soviet-made super heavy-lift launch vehicle designed to land crewed Soviet spacecraft on the Moon.
[1][2] The Zond capsule was equipped with a dummy lander and cameras to photograph the lunar surface for possible sites of a crewed landing.
But at 25 seconds after lift off, the control system throttled back the working engines, as there was too much vibration.
At an altitude of about 30 km, just 66 seconds after liftoff, the engines again were set to full power.
[4][5][6][7][8][9] NASA used the Saturn V rocket for lunar missions, a super heavy-lift launch vehicle like the N-1.
