Did this astronaut cover up a UFO sighting?

It's a UFO, fans believe, and proof that NASA is in cahoots with aliens.

No chance!

See: Pic of South Africa is just incredible

I had a look at the video and I think it's a load of rubbish, but now I'm asking you to be the judge and let me know your thoughts.

An alien hunter claims that a video of an astronaut moving his hand ‘deliberately’ in front of a camera is proof something fishy is going on in space and he's trying to conceal the object.

Is this a UFO or is it just reflections and space junk?
