The following caught my eye today:
Not sure if they are fitted out for light-saber practise yet though.
I didn't know they'd had similar ones buzzing around inside the ISS since 2006, what an excellent idea. Couple that with Robonaut and the 3D printing experiments, plans for capturing small asteroids etc.
Makes for an interesting thought, send a robot and 3D printer to remote place in the solar system, then task it with building various robots to explore and perhaps even prepare the place. Keep collecting materials, and building more things. Sounds plausible that we could have general purpose robot-manned ships working in various places in space (although what advantage does a robot have over a typical purpose built probe). What useful things could be created in these locations, which can then be useful?
But how awesome (aside from our natural nature to go to places and mess it up with our stuff)!
A common issue which keeps cropping up is that we are very poorly designed for space, particularly long periods and specifically when it comes to accepting the large amounts of radiation out-there (at least from my low understanding). However, it is something we will have to overcome (one way or another) if we are going to go anywhere.
The fact that travel is likely to take a very long time IS an issue, but that probably isn't that huge (given enough money it is feasible to build a self-sufficient environment), keeping people alive that long sure is. I wonder if this is something which will come from advanced materials or medically we adapt our bodies to, or even...getting far fetched here and into moral muddy water...are specifically bred for genetically...
