[@andywomack3414]

Thanks for replying. I would rather have solar system research money use on machines like the moon and Martian rovers, space telescopes and other automated observatories instead of on humans in space. Advances in AI will make these machines even more adept than they are now. The more we learn about our solar system, the more prepared we will be should there be reasons for humans to accompany these machines on their journeys. A major emphasis should be the detection and tracking of near-earth asteroids and comets, not simply for protection, but as possible sources of metals. I doubt that science-fiction will become real any time soon, and I fear humans in space now is wasting time.

Turning this lava tube entrance into a habitat:: Create landing pad/runway outside, place solar arrays all around with cables running under the regolith and down the hole, place elevator and stairs down and then put a pressure dome over the entrance, barricade both ends of the lava tube internally, pressurize the space and fill it with a breathable atmosphere, drill into the wall and install a nuclear plant as a backup power source, construct habitat modules inside. The walls of course would have to be tested for stability and shored up as needed.

Good idea, however, soil and stone gas permeability would be the first thing to establish. This would give some protection from asteroids, which are a primary concern to moon structures.

Mercury would probably have gemstones way rarer than diamonds. Radiation sometimes changes the structure and/or composition of crystals and gives them unique properties.

“Significantly, these [reduction spheroids] are likely the only biosignatures for subsurface microbial life that you could see with your eye-or the cameras on our rover,” says David Flannery, an astrobiologist and member of the Perseverance science team at Australia’s Queensland University of Technology. But because these structures can also arise from purely abiotic processes, they can’t solely constitute iron-clad evidence for past life-especially when they’re being remotely studied by a robot on an alien world located millions upon millions of kilometers away. Even on Earth, Flannery says, “there is surprisingly little work on [reduction spheroids], in part because it’s so hard to understand these things.”
