Mission Summary

The Pioneer 3 mission was one of the first attempts by the United States to send a spacecraft to the moon. Because of a malfunction with the spacecraft's booster rocket, it lacked the velocity to make it beyond Earth orbit and fell back to Earth, burning up over Africa.

Pioneer 3 was, however, equipped with a Geiger counter to study interplanetary radiation and managed to discover and map the outer Van Allen radiation belt around Earth before its demise.
