Wow, that's beautiful.

In a recent thread that touched on this OneTrikPony posted some very promising studies being done in artificially boosting muscle mass and preventing bone loss in zero-g. It looks like we'll likely see major reductions in the physical tolls of space living in the next decade or so. There'll likely still be the issue though, no matter how successful we are at genetically modifying our meat and bones to resist deterioration, of preserving motor skills necessary to moving our bodies under load - and that's really a function of the brain moreso than the body. Putting even a perfectly-adapted space human who has spent years in micrograv into 1g conditions and asking them to bend down and pick a tennis ball up off the floor would be like you or I doing a standing backflip into a handstand. Most healthy young people will have more than enough strength in their muscles to do the gymnastic feat, but unless you've trained that specific skill from a young age the neurological connections needed to apply that strength and steer your bodyweight just won't be present. Having muscle mass doesn't necessarily mean the brain knows what to do with it - if that were the case physiotherapists would be replaced by steroids, and Ronnie Coleman would be the most healthy and athletic human in the world. So physical education in zero-g will always be imperative, unless the plan is to never go back into a gravity environment, at which point there's as much sense staying in this prehistoric monkey body as there would be to keep pedaling a bike when you're floating in the sea.

Such a configuration would certainly reduce the cost of entry for being fit and healthy. And might have far reaching consequences depending on how effective your muse might be at exercise. "I spent the last 6 years playing a virtual MMO, and now I'm an Olympic bodybuilder!"

has anyone seen an explanation of the blue/purple glow at the bottom of the frame? In other pictures it's in the middle of the frame clear across the sky. Doesn't look like lens flare. What causes it?

That makes sense, Thank you! That's been nagging at me. I didn't understand the distances involved and the shots from behind Saturn really makes it look like the flare of the E-ring is in a different plane.
