The article doesn't seem to answer the question of why the heat plume distributed stuff on the nearside rather than evenly, or on the top side. If the south pole was hit, it seems like the heat should flow evenly on both sides, and if anything case the deposition to happen towards the north pole, rather than the near side.
- waynecochran 5y agoYes -- that is what I was wondering. The following statement is given with no explanation -- was Earth's gravity involved? As the heat plume spread beneath the Moon’s crust, that material was eventually delivered en masse to the nearside.
- andrewflnr 5y agoReading the linked paper and Wikipedia, it looks like the center of the KREEP concentration is roughly antipodal to the impact crater, which itself is not exactly on the south pole. So at least the symmetry side of things is in order. But yeah, this PR article is exceptionally bad at taking a long time to say almost nothing of interest.
