Photoshopped mate, you can see the tether in the reflection of the helmet, also thats a lot of open water and the clouds look real uniform.
though it is from a govt. site so what do I know.
the second one might be real though, they got the little jet pack thing so they should be fine.
* I take that back, after closer inspection it is indeed his\her arm not the tether, still the last picture is crazy though, must have been dare night on the ISS
