I and several others simultaneously figured it out on the basis not only of the patent absurdity of it but also from the uninflated condition of the actor's suit. We were naturally pleased when the studio who made it came clean about it. What impressed me most was how they managed to simulate the ghosting of a 1970s orthicon pickup tube -- they actually obtained and refurbished a vintage camera.
I put this together for one YouTuber who claims the two have
exactly the same setting:

Anyway, let's see if any astute hoax nuts can find any differences between the pictures. They are, after all, such assiduous photo-analysts!
I've also come across the "Mr. Gorsky" story, which is quite entertaining. And of course, it's a deliberate clue that the video is fake.
I noticed the limpness of the suit right away, too. I also noticed that the ladder in the hoax video was much lower to the ground than the one in the real clip.
I guess I was wrong about this being used in a commercial. The Snopes article said that the producer of the hoax video was a space exploration enthusiast who was mocking the hoaxers. Good that you were able to contact him. Is there a public link to his comments on this?
