So scientists on Earth, detect chemical compounds found on Earth, in rocks found on Earth.
Does that pretty much sum it up?
Moon meteorites found on Earth contain trace gasses that lend further support to the widely held belief that our largest natural satellite formed from chunks of our planet that were ejected in a massive impact. Patrizia Will, a doctoral research student at ETH Zurich, studied six separate Moon rocks picked up by NASA in …
I was trying to breed tens of thousands of cockroaches to invade and destroy Britain's nuclear armed subs. Nobody approved of this but I needed to know how.
My niece had a zoology degree, probably still has, so I asked her how to breed tens of thousands of cockroaches. "Well, you take a little boy cockroach and you take a little girl cockroach, and..."
Helium and neon are not found only on Earth. Saying that the Moon gases are of Earth origin because they're present is not science, it barely qualifies as a guess. They'll need more than saying they're present to prove it.
That, of course, will be difficult to prove, but I guess talk is cheaper. But for all we know, the Moon was supposed to be the 10th planet (or 11th, what with the asteroid belt) but was caught up by a faster growing Earth's gravitational pull and lost the race.
What I'd like to see in my lifetime is a mission to the asteroid belt to bring back some samples, and have them compared to Moon regolith. It would be interesting to see if the Moon actually came from there.
Yes, but no. The asteroid belt is between Mars and Jupiter while Bennu is between Earth and Mars. Neat looking mission though, and will be looking forward to the results of that one as well.
For the rest of you, no idea why so many downvotes. All collected data is valuable, and hard data is better than theories. I just don't think the presence of helium and neon is evidence of origin. Unless it was the implication that Pluto is a planet, which as far as I'm concerned it is. If it was big enough to be found back when the Model T was considered advanced technology, it qualifies to be grandfathered in as a planet.
