OK, I admit, I'm linking to this because I love the idea of a virtual spacewalk and I want to try it as soon as I can! That said, reading through the article naturally brings to mind additional thoughts. Like: what if I want to move? How would they handle that? In space, you could move in a full 360x360 degree sphere of directions, presumable with some simple jet-pack controls (one of the reasons I like No Man's Sky so much is that it really allows you to move freely and fluidly through the environment). But capturing the video for this kind of movement would create a crazy amount of data! I imagine we would scale up to is, and full-motion VR would be quantified by some sort of 3d movement resolution scale. The lowest would be '2', which is what we get in Google Street View - forward and backward, or maybe '4', which is what we get at an intersection. Maybe '6' would also allow you to move up and down. And so on.
