Cernan

Apollo 17's Eugene Cernan warned the dust would be "one of the most aggravating, restricting facets of lunar surface exploration."

American astronauts Gene Cernan and Harrison Schmitt — on Dec. 14, 1972 via Apollo 17 — were the last humans to set foot on the moon, concluding the Apollo moon mission.

Stafford’s next flight in 1966 was with Cernan on Gemini 9.

Cernan’s spacewalk, connected to a jet-pack like device, didn’t go well.

Cernan complained that the sun and machine made him extra hot and hurt his back.
