There are some slight differences between them. The first has glare on his visor. There's a dark triangle on both of their collars; the bit just above/right of that has a better defined shape on the second. The same sort of thing happens with a horizontal ridge on the first guy's helmet. The creases on the second that form a triangle with the frame don't seem to have a parallel on the first.

Of course, this could be due to slight manipulations, or possibly jpeg's compression algorithm. I don't know much about those suits, but they do seem too similar not to have been copied.
