I do not think. There will ever be, anything on the moon. No water you see. If you have to transport water. It would cost more than gold. At the moment.
Mars is another story. There is water there. It is the amount of time, it takes to get there. Which is the problem. I believe 6 months. So 6 months there and 6 months back. Plus time of stay. The problem at the moment. Is that the muscles will waste away. When they come over this problem. Then they might be trips to Mars.
If you get a chance. Read 'Red Mars;. by Kim Stanley. It is on this subject. Very Good.
