The “C” rock

A rock with a letter on it, like a prop.

The strongest version of this theory

Film crews label their props.

A clear, symmetrical letter on a rock looks like a set-dresser’s label. Prop rocks are numbered or lettered in film studios. If the letter is on a NASA photo, it suggests the rock was placed. [1]

What the film shows

Check the original, not a copy of a copy.

The Apollo Lunar Surface Journal lists the frame as AS16-107-17446, with a neighbor, 17445, taken moments before. The high-resolution scans of the original show no letter. [1]

The “C” appears in some later prints and scans, at slightly different shapes. The planetary scientist Stuart Robbins compared versions and concluded it was most likely a hair or fiber on the print or scanner. [2]

What we can’t tell you. We did not inspect the original transparency; we rely on NASA’s scans and Robbins’s comparison.
