Mission summary
Apollo 17 was the sixth and final crewed lunar landing, and the longest. Cernan and Schmitt landed in the Taurus-Littrow valley — chosen so a single landing site could yield both old highlands material and younger mare basalts — and conducted three EVAs totaling 22 hours, the longest cumulative surface time of any Apollo mission. Schmitt, the only professional geologist to walk on the Moon, discovered orange volcanic glass at Shorty Crater that revealed explosive volcanism in the Moon's distant past. Cernan's final step into Challenger before liftoff made him the last person to walk on the Moon to date. The May 2026 PURSUE disclosures surfaced an in-mission UAP-flash observation by the Apollo 17 crew over the Grimaldi crater on the western near-side limb.

Objectives
- Final J-mission — longest surface stay (~75 hours) and longest cumulative EVA time (~22 hours).
- First and only night launch of the Saturn V.
- First professional geologist on the Moon (Schmitt).
- Investigate the Taurus-Littrow valley, sampling both highlands material and mare basalts at one site.
- Deploy the fifth and final ALSEP.

First and only night launch of the Saturn V from LC-39A. Liftoff was delayed 2 hours 40 minutes by a launch-sequencer fault — the longest hold in the program.

| 1972-12-11 19:55 UTC | Cernan and Schmitt landed LM 'Challenger' in the Taurus-Littrow valley. |
| 1972-12-11 to 1972-12-14 | Three EVAs totaling 22 hours 4 minutes — longest cumulative EVA time of any mission. LRV traverses out to South Massif and the Sculptured Hills; cumulative LRV distance ~35.7 km. |
| 1972-12-12 | Schmitt discovered orange volcanic glass at Shorty Crater — evidence of explosive lunar volcanism roughly 3.5 billion years ago. |
| 1972-12-14 22:54 UTC | Cernan re-entered the LM after Schmitt — last person on the Moon. His parting words: 'we leave as we came and, God willing, as we shall return, with peace and hope for all mankind.' |
| 1972-12-17 | Evans conducted a 67-minute trans-Earth coast EVA to retrieve film cassettes from the SIM bay. |
| 1972-12-19 19:25 UTC | Splashed down in the Pacific; recovered by USS Ticonderoga. |
