Metcalf-Lindenburger is secured with her feet locked into a Portable Foot Restraint carried by a mini Sub that's role-playing a Space Exploration Vehicle.
Aquanaut Steve Squyres from Cornell University has been
blogging about his adventure beneath the surface. "Just like any other field scientists, we started with reconnaissance, flying above the surface with jet packs and reporting back to Mission Control what we discovered. On the spot, they came up with a science plan for us, just as would happen with a crew at an asteroid. And then it was up to us to use all the tools we had at our disposal, in whatever way we thought best, to carry out that science plan."
