Nice pics ! A bit blurry though.
I don't suppose they have HD cameras out there yet. Obviously, the problem is not buying the kit, but making sure new kit would work flawlessly with the rest.
Oh, and there's the cost of getting it up there and putting it in place as well. And the fact that a spacewalk is a potentially dangerous thing, so keep 'em to what is needed.
Okay, so no HD. But what's with all the numbers ? Do they really need all that data all the time ? (independantly from the fact that it's NASA, so if they have it, they most certainly need it).
