Discovery of 50km cave raises hopes for human colonisation of moon
"Using a radar sounder system that can examine underground structures, the orbiter
initially found an opening 50 metres wide and 50 metres deep, prompting speculation that there could be a larger hollow. This week scientists at the Japan Aerospace Exploration Agency (Jaxa) confirmed the presence of a cave after examining the hole using radio waves. The chasm, 50km (31 miles) long and 100 metres wide, appears to be structurally sound and its rocks may contain ice or water deposits that could be turned into fuel, according to data sent back by the orbiter, nicknamed Kaguya after the moon princess in a Japanese fairytale."

Radio isn't going to work well, and while an autonomous rover sounds like a good idea, they work best when we already know the terrain. In theory a lava tube should be relatively smooth on the inside except for chunks that have fallen from the ceiling, there's no guarantee what we know about lava tubes here on Earth cleanly translates to how they'd form on the Moon, or how this particular one would form. So, you really want to have someone on site. And once you do, you might as well just use them to explore the tube. And trust me, there's no shortage of cavers here on Earth that would be willing to check out a lunar lava tube. I'm probably a bit too old to go, but you know, I've got some time to spare if NASA is willing to provide transportation. -- Greg D.

Radio isn't going to work well, and while an autonomous rover sounds like a good idea, they work best when we already know the terrain. Place a transmission station at the entrance. That'll do until there's a bend. So bring along a relay for each bend. Otherwise, a cable connection would have to be laid as the rover roves. Let's ask Comcast. :-) In theory a lava tube should be relatively smooth on the inside except for chunks that have fallen from the ceiling, there's no guarantee what we know about lava tubes here on Earth cleanly translates to how they'd form on the Moon, or how this particular one would form.
