Failed · Failure
The fourth Surveyor soft-lander; after a flawless flight to the Moon its radio signals ceased during terminal descent, about 2.5 minutes before planned touchdown, and contact was never reestablished.

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.
