The crew of Apollo 17 addresses a joint session of Congress after the completion of the final Apollo Moon landing mission.

Apollo 17 was the eleventh and final mission of NASA's Apollo program, the sixth and most recent time humans have set foot on the Moon. Commander Gene Cernan and Lunar Module Pilot Harrison Schmitt walked on the Moon, while Command Module Pilot Ronald Evans orbited above. Schmitt was the only professional geologist to land on the Moon; he was selected in place of Joe Engle, as NASA had been under pressure to send a scientist to the Moon. The mission's heavy emphasis on science meant the inclusion of a number of new experiments, including a biological experiment containing five mice that was carried in the command module.

A joint session of the United States Congress is a gathering of members of the two chambers of the bicameral legislature of the federal government of the United States: the Senate and the House of Representatives. Joint sessions can be held on any special occasion, but are required to be held when the president delivers a State of the Union address, when they gather to count and certify the votes of the Electoral College as the presidential election, or when they convene on the occasion of a presidential inauguration. A joint meeting is usually a ceremonial or formal occasion and does not perform any legislative function, and no resolution is proposed nor vote taken.
