The YouTube video analyses alleged NASA original footage of the 1969 fourth Moon mission and concludes it shows an astronaut inside a space capsual orbitting the Moon with no signs of weightlessness, reports Dailystar.co.uk.

Apollo 10 did not include a lunar landing, but there was a succesful orbit of the Moon.

There is no gravity in space, meaning astronauts would be weightless inside the capsule as it orbited the Moon.

The videomaker suggests a reflection seen in the glass of the capsule in the footage is one of the astronauts… but he is moving as if he were on Earth rather than displaying any signs of weightlessness.

It is claimed the figure, who has the American flag badge still visible on the space suit, alternates between seating and an upright position.

The uploader wrote: “On the right side of the screen, you can see the astronaut’s reflection in the glass.

“His shoulder is still visible as he turns again, and shockingly he turns and walks away.

"He even seems to be striding away and we can see him adjusting his pants as he does.

“What’s shocking about it is that there is absolutely no weightlessness.
