Due to a ground error in an antenna that transmitted guidance information to the launch vehicle, the Blok Ye upper stage of the launch vehicle fired longer than intended and the probe missed the planned Moon impact.

Thor performed as expected and Agena ignited to inject its payload into orbit. As the vehicle crossed the horizon and passed out of range of tracking, the mission was proceeding to plan, and the US Air Force announced the successful launch. Only when the spacecraft failed to check in did it become apparent that it had not reached orbit: something had gone wrong while the rocket was out of communications, although the cause of the failure was never established.

The first U.S. spacecraft to reach Earth escape velocity.

Stage 2 damaged at seperation.

No teleemtry after Agena ignition.

Inertial system failed at 153 seconds after launch. Vehicle destroyed by range safety.

Stage 2 propulsion malfunction.

Insufficient stage 2 velocity.

Control lost after 5.5 sec. Destroyed by range safety.

First stage shut down too early

The spacecraft successfully impacted the surface of the Moon.
