Conspiracy theorists got something new to talk about Thursday when YouTube user Streetcap1 posted a video analyzing a photograph from NASA’s 1972 Apollo 17 mission, the last crewed mission to the moon. Streetcap1 claims in text that precedes the video that a figure seen in a reflection in the photograph is of a “stagehand” and not of another astronaut.

This is the photograph — taken from the official NASA archives — that Streetcap1 is talking about in his video, which he has titled “Reflection in a Visor.”

Apollo 17 Conspiracy Theory

Zooming in on the visor the astronaut is wearing clearly shows another human figure reflected in it. And it is Streetcap1’s contention this second figure is not another astronaut, but someone on a fake moon landing set. And he reaches this conclusion because, insofar as he can see, the figure in the reflection is not wearing a spacesuit or a helmet.

In his analysis of the zoomed-in photograph, which makes the reflected figure quite blurry, Streetcap1 says the figure “looks like a man… back in the early 70’s, long hair, you know, wearing some sort of a, I don’t know, waistcoat-type thing.”

Streetcap1 also says in the video he actually believed the moon landings happened, till as recently as a few days before he posted the video. But this photograph has now made him doubt if the landings did, in fact, take place.

The video has been viewed over half a million times already, and a number of comments below it lauded Streetcap1 for finding this “proof” of the lunar landings being a conspiracy. But there were also a large number of responses that explained how the reflection was of another astronaut on the moon’s surface. There was, for instance, a video titled “Streecap1 is wrong, RE: Reflection in a Visor” uploaded Sunday by a user called Incredibly British.

This is, of course, not the first time that conspiracy theories about the moon landings have surfaced. Right from the first Apollo mission to have landed on the moon — Apollo 11, carrying Neil Armstrong, Buzz Aldrin and Michael Collins to the surface on July 20, 1969 — there have been suggestions that the whole thing was a set-up. The “flag in the breeze” conspiracy theory has been addressed and explained by NASA as the consequence of a problem with the flag’s deployment mechanism.

Apollo 17 was the sixth and the last mission — by NASA or any space agency — that carried humans to the moon’s surface. The crew was made up of Eugene A. Cernan, Ronald E. Evans and Harrison H. Schmitt. The spacecraft landed on the lunar surface Dec. 10, 1972, and left four days later.
