Failed · Failure
Ranger 5 was a Block II Ranger similar to Rangers 3 and 4, intended to photograph the Moon during descent and deliver a seismometer capsule to the surface. An unknown malfunction after injection left the spacecraft without power, its batteries ran down after 8 hours and 44 minutes, and it missed the Moon by 725 km.

Chronology
Mission timeline
Milestone
Ground stations sent midcourse maneuver commands
JPL records SC-1, SC-2 and SC-3 command sequences beginning at 23:50 GMT on October 18 and repeated at 01:03–01:07 GMT on October 19. The command record documents an attempted sequence, not a completed spacecraft velocity change; JPL reports battery exhaustion before the maneuver was complete.
EarthMilestone
Battery power was reported exhausted at approximately 01:45 GMT; intermittent solar-powered transponder tracking continued as the spacecraft tumbled

Time-dependent navigation trajectory
Source states place the model at the selected time. Reconstructed flight, estimates, predictions and historical mission plans are identified by interval; gaps remain visible.
Source records and sampling assumptions are retained with the repository data. Model attitude and surface appearance are illustrative.
