There are probably a dozen small companies now, not just in the US, but one or two in Japan. The cost per kilogram of delivery to the Moon is going down rapidly. So it's a whole new goal game for doing things on the Moon. Would you go as a tourist to the Moon if you could afford it? Probably much younger, yes, I jump in the thought. Right now, I don't think my mobility would get me well,. Even though the gravity is lower, that would help a bit.
The Earth's atmosphere is good for some things, like providing something to breathe. But it does get in the way of astronomers, who have been successful at launching orbiting telescopes into space. But gravity and the ground are also useful for certain things, like walking around. The Moon, fortunately, provides gravity and a solid surface without any complications of a thick atmosphere -- perfect for astronomical instruments. Building telescopes and other kinds of scientific instruments on the Moon is an expensive and risky endeavor, but the time may have finally arrived. I talk with astrophysicist Joseph Silk about the case for doing astronomy from the Moon, and what special challenges and opportunities are involved.
