Good point. I guess what I was trying to express that just floating in LEO is fairly boring.  My example of a moon base would be much more thrilling, especially if it could serve as a dark-side radio telescope or even as a space-port for deep launches.<p>A lot of little experiments an LEO ferrying back and forth is something we&#x27;ve been able to do since at least the 60&#x27;s. I would love to see some next-gen stuff and with the SLS I will.  I think NASA is very committed to a manned asteroid mission and a return to the moon.
