Failed · Failure

Ranger 3 was the first of the Block II Ranger designs, built to televise the lunar surface during descent and rough-land a seismometer capsule on the Moon. A series of malfunctions beginning with a booster guidance error left it on the wrong trajectory, and it missed the Moon by approximately 36,800 km and entered a heliocentric orbit.
