Two N1 Moon rockets appear on the pads at Tyura-Tam in early July 1969. The N1 was designed for the Soviet space program human lunar missions. In the foreground is booster number 5L with a functional payload for a lunar-orbiting mission. In the background is the IMI ground test mock-up of the N1 for rehearsing parallel launch operations. After take-off the rocket collapsed back onto the pad, destroying the entire pad area in a massive explosion.
