HEAVILY SOILED WITH LUNAR DUST.
Flown to the lunar surface on Apollo 17, LM Lunar Surface Checklist, pp 2-3 and 2-4. A single sheet printed recto and verso. NASA/MSC, September 12, 1972. 8 x 5½ inches.
EXTENSIVELY HANDLED JUST PRIOR TO AND AFTER EACH OF APOLLO 17'S THREE EVAS. The checklist gives the procedure for "transition to one-man EVA," in the case of something preventing both crew members from venturing onto the lunar surface. On the reverse are instructions for "LM repress failure procedure."
As Gene Cernan explains in the letter of certification that accompanies the checklist sheet, "This particular page ... had special meaning to Jack Schmitt and I while on the surface, as it would have been needed for reference had only one of us been able to go out for a moonwalk due to the failure of one of our PLSS backpacks. Thankfully these emergency procedures were not needed as both life-supporting backpacks worked exactly as designed. After our last moonwalk, while safely back inside the LM, Jack and I commented on the special significance of this very page from the Moon to Bob Parker (CAPCOM):
172:05:43 Cernan: Hey, Jack and I are going to frame this page 2-3, cut it down the middle and each take half.
172:05:58 Schmitt: I'm going to take the front half. Gene will take the back half.
When back on Earth, we never got around to cutting this page in half, and luckily we never had to make that tough decision as to which one of us would have gone out for that one-man moonwalk.
Due to the heavy use of this checklist, the clearly visible dark smudges on both sides of this page are, indeed, smudges of actual lunar dust from the Taurus-Littrow Valley!"
The sheet itself with hand-stamp reading "Landed on the Moon aboard the Apollo 17 LM 'Challenger'," and SIGNED by GENE CERNAN. Also included is a photograph of Cernan with this sheet, a one-page mission transcript detailing the above conversation of the last men on the Moon about this sheet, and a set of both iconic and lesser-known images from the Apollo 17 mission in digital format.
