There was a malfunctioning light on the craft's service propulsion system (SPS); after considerable troubleshooting, the astronauts did a test burn of the system that also served as a midcourse correction.

The "Intrepid" lunar module descent stage, experiment package (ALSEP), "Surveyor 3" spacecraft, and astronaut footpaths are all visible. In 2011, the LRO returned to the landing site at a lower
