NASA's Surveyor 2 was supposed to make a soft landing on the Moon, but a thruster failed to ignite, putting the spacecraft into a spin. The lander crashed on the Moon.
Sept. 20, 1966: Launch
Sept. 23, 1966: Lander crashed on the Moon
Surveyor 2, similar in design to its predecessor, was aimed for a lunar soft-landing in Sinus Medii. During the coast to the Moon, at 05:00 UT Sept. 21, 1966, one of three thrusters failed to ignite for a 9.8-second course correction, and as a result, put the spacecraft into an unwanted spin.
Despite as many as 39 repeated attempts to fire the recalcitrant thruster, the engine failed to ignite, and Surveyor 2 headed to the Moon without proper control.
Just 30 seconds after retro-fire ignition at 09:34 UT Sept. 22, 1966, communications ceased, and the spacecraft crashed on the surface of the Moon at 5 degrees 30 minutes north latitude and 12 degrees west longitude, just southeast of Copernicus crater.
