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 on 21 September, one of three thrusters failed to ignite for a 9.8-second midcourse correction and thus 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 on 22 September, communications fell out, and the lander crashed onto the surface of the Moon at 5°30' north latitude and 12° west longitude, just southeast of Copernicus crater.
