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."

Moon colonization – many lava tube caves, water and high amounts of titanium:
"The moon has many hundreds of large lava tube caves. The Lunar Reconnaissance Orbiter has now imaged over 200 pits that show the signature of being skylights into subsurface voids or caverns, ranging in diameter from about 16 feet (5 meters) to more than 2,950 feet (900 meters), although some of these are likely to be post-flow features rather than volcanic skylights."

A rover could go in, take a look around and come back to tell us what it saw. And how do you navigate? 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.

And send a human with it? Communication lag between your volcano robot and the operator is? A few seconds. No big deal like the 8 hrs to Pluto. The robot could use automonous driving like rovers do. Simple way is to take a look, go a bit, take another look. Quick reactions aren't required of a plodder. |
