The cuff checklist worn on the moon by Apollo 17 astronaut Gene Cernan could sell for more than $800,000 during a sale at RR Auction this month.

Cernan
wore the EVA-3 checklist for more than seven hours during his
exploration of the lunar surface, and the pages are smudged grey with
lunar dust.

The
checklist includes instructions for mankind’s last moonwalk and
Cernan’s handwritten notes on his speech, which became the final
words ever spoken on the moon.

According to the auction house, the cuff checklists worn by Cernan during his first two moonwalks of the Apollo 17 mission (EVA-1 and EVA-2) were sold privately, making this example the only one to be offered at public auction.

It
will now cross the block as part of RR Auction’s Space and Aviation
Auction, which runs online from October 8 until October 15.

During
the last Apollo Moon mission on December 14, 1972, Cernan gave his
moving speech as he stood next to the American flag.

“I
think probably one of the most significant things we can think about
when we think about Apollo is that it has opened for us—’for us’
being the world—a challenge of the future. The door is now cracked,
but the promise of the future lies in the young people, not just in
America, but the young people all over the world learning to live and
learning to work together.”

Cernan can be seen wearing the checklist in several photographs taken during his final moonwalk, and film footage of the event shows him flipping through the pages.

The
cuff map included routes, geological landmarks and his list of tasks
for each location during EVA-3.

During
his exploration, Cernan even spoke of the checklist he was wearing,
saying: “Man, I tell you, this little navigation map I’ve got on my
cuff checklist is unquestionably the greatest thing that I’ve ever
done.”

He
later spoke of its usefulness in the Apollo Lunar Surface Journal:

“It’s
like a watch. Where’s the most convenient place to put a watch? On a
wrist. Not in a pocket. Pocket watches are nice, but the most
convenient place to put it is where you can glance at it easily.
That’s why the cuff checklist, itself, was a great idea; and putting
the maps in made it even better…By the time of Apollo 17, the cuff
checklist wasn’t just a checklist of the things you wanted to do, it
was a geologic flight plan.”

The
historic cuff checklist remained in Cernan’s personal collection for
45 years until his passing in 2017, and will now be offered at
auction for the first time by his estate.
