Large flown double-sided 10.5 x 16 cue card used inside the Lunar Module during preparations for the second EVA of Apollo 15, consisting of two cards which were taped together at the center, with one side headed “EVA 2 PREP” and the other headed “POST EVA 2,” signed and certified in blue ink, “Flown to the lunar surface aboard the lunar module ‘Falcon’ during Apollo 15, July 26-Aug 7, 1971. Dave Scott, Apollo 15 CDR.” This cue card was attached to the internal Alignment Optical Telescope (AOT) support bracket of the spacecraft by the taped upper tab during the EVA preparations and post-EVA periods. In fine condition, with cue cards neatly detached. From the personal collection of Dave Scott.
Accompanied by a signed letter of provenance from Scott, in part: "I hereby certify that the large double-sided 'EVA 2 Prep' / 'Post EVA 2' Cue Card included with this letter was used on the lunar surface aboard the Falcon Lunar Module during Apollo 15...To facilitate use during the EVA preparations and post-EVA periods this cue card was attached to the internal AOT support bracket of the spacecraft by the tab taped to the top." Scott describes the activities covered by the cue card, including preparing equipment, donning and checking the Portable Life Support System (PLSS), systems preparation, and donning the helmet and gloves. The reverse continues the preparation sequence, including suit pressure checks, cabin depressurization, and preparation for egress. The letter continues, "Due to the complexity and number of activities required for both performance and safety, the cue card replaced a detailed written checklist, and was essential to minimize the time required for all of the EVA-2 PREP tasks, which, excluding the prior donning of the space suits, required approximately two hours."
Two of the most significant lunar exploration results in the entire Apollo lunar program were discovered during the second EVA of Apollo 15. CDR Scott and LMP Jim Irwin recovered huge amounts of soil samples at Station 6 (Apennine Front) and Station 7 (Spur Crater), the latter being the site of two utterly unique lunar finds: the ‘Genesis Rock,’ a large sample composed primarily of anorthite and formed in the early stages of the solar system, at least four billion years ago; and the 'green rock,' which, almost 40 years later, was discovered to contain water molecules, findings that pointed to the existence of water deep beneath the moon's surface. A fantastic flown cue card which was used inside the LM Falcon before and after this historic lunar excursion.
