Pioneer P-3 Mission Failure
Pioneer P-3 (also known as Atlas-Able 4 or Pioneer X) was an American mission that was intended to be a lunar orbiter probe, but failed 70 seconds after launch. The objectives were to place a highly instrumented probe in lunar orbit, to investigate the environment between the Earth and Moon, and to develop technology for controlling and manoeuvring spacecraft from Earth.
