Launch
Clementine launched from Vandenberg Air Force Base
Milestone
Thruster malfunction ends the planned Geographos flyby
An attitude-control thruster fired for 11 minutes, exhausting fuel and ending the planned observations of asteroid 1620 Geographos.
1620 GeographosMission end
The mission ended when telemetry was no longer intelligible

Trajectory record
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.
