  1. Very nice overview! A new visit to the Moon is long overdue. We could do so much more than was possible in a few days 50 years ago. I find it sad that we have declined so much. The US can’t even put a man (woman) in space anymore, let alone land on the Moon. So much for progress.

    You may be interested in the gravity maps of the Moon, made 5 years ago by the Grail mission. See for instance
    https://www.theguardian.com/science/2012/dec/06/gravity-map-moon-formative-years

    I don’t buy the 1178 event attributed to the formation of a large lunar crater. Such impacts are very rare and the chance of catching on in recorded history is near zero. Neither does the description sound like an impact. Their description sounds much more like something in our atmosphere, for instance passing hot air from a distant fire.

  2. Thanks, Albert for your kind words. Best wishes for a very Merry Christmas to you and yours.

    The interesting part of this for me was as time went on and the supply of magma diminished, volcanic activity started looking more like what we are used to here on earth (and elsewhere).

    Saw the Grail maps. Still trying to figure out how they were used to identify lava tubes. Wouldn’t have thought there would have been much of a difference in local gravity, but what do I know?

    Have been interested in Archaeoastronomy (Paleoastronomy) for a long time as much as a mystery to be solved as anything else (how did this come to be and why?). Look at TLPs in that light, with the answer (as always) being we need more information / data. Have been doing the same thing for nearly a decade with the YD / Fred Hoyle / Mike Baillie / Napier / Clube giant fragmented comet discussion.

    I think we will be back on the moon much faster than anyone thinks today with perhaps the ChiComs, Bezos and Musk fighting it out for first one back. Even Bigelow is talking about orbiting one of his Transhab-based modules in the vicinity. Next ten years is going to be a lot of fun. Cheers –

  3. If there is as much water as recent informacion is saying on the Moon’s Inner layers,I do not see any reason way It should not be any primitive kind of live.we know that here on Earth buried on the depths of the deepest océans where there is no oxígen,there are primitive forms of live.

    • The water ice we’ve found on the moon via remote sensing (a possible problem as you never really know until you have a chunk of it in your hand) is thought to be delivered via impact events and is resident on surface craters. At this point, we can only guess how much there is in the mantle. If the 3-4 most likely theories of lunar formation are correct, that quantity sits somewhere between the highly technical terms “not much” and “doodly squat”, loosely translated as none (/sarc and entirely tongue in cheek).

      OTOH, Earth’s mantle seems to be quite wet, with water being wrung out of the subducting plates at the ringwoodite layer some 6 – 700 km deep. Problem is that is too deep for life as we know it, as we haven’t found anything nearly that deep and don’t know if what is coming up is contaminated as it passes through the shallower layer of known deep bacteria. It’s a great mystery / science problem and as usual, the more we think we know, the more we actually find out we don’t. Only solution? Keep looking and be amazed at what we find. Best to you and yours. Cheers –
