The massive subsurface has a deposit of a dense material which is assumed to be a metal. Aitken is on Lunar Astronautical Chart 86 and surrounding charts, but the site is down, so no links. lunar cataclysm (inner solar system cataclysm) hypothesis. The 21-km-diameter Shackleton Crater is comparable in size to a city, shown here in comparison to the city of Houston, home … The Moon's Farside Von Kármán Crater The intense interest surrounding the sampling of ancient materials from the lower crust or upper mantle of the Moon has a focus on the old, deep, South Pole-Aitken (SPA) basin on the farside – a rallying point because the oldest, deepest basin should have excavated the oldest, deepest rocks. So I would have to say that scientists have known at least as long as these craters … A close-up view of Aitken from the northeast. The point opposite Aitken on the circumference is the Moon's South Pole. The Moon's Farside Von Kármán Crater The intense interest surrounding the sampling of ancient materials from the lower crust or upper mantle of the Moon has a focus on the old, deep, South Pole-Aitken (SPA) basin on the farside – a rallying point because the oldest, deepest basin should have excavated the oldest, deepest rocks. T. Takata, Geological Inst., U. Tokyo (Hongo, 7-3-1, Bunkyo, Tokyo 113 JAPAN, t firstname.lastname@example.org). (a) Radar images from the Apollo 17 Lunar Sounder Experiment (ALSE). It makes up nearly a quarter of its entire surface area.
These samples will also provide a measure of the impact flux (and its variations) throughout lunar history. It is notable in that its floor is filled by a mare deposit, and that it, along with the Moon’s South Pole, is the namesake for the biggest and most ancient lunar basin, South Pole-Aitken Basin ().Within its flooded floor are many scientifically interesting features, one of which are wrinkle ridges. The latest study , which is quite recent in 2019, has suggested that the SPA basin may contain a massive chunk of metal that is estimated to be larger Hawaii’s Big Island. The crater Aitken (16.8ºS, 173.4ºE) is imaged at right in all four panels. Far Side Moon: Aitken Crater - posted in Lunar Observing: 130km Aitken crater, on the far side of the Moon, on the northern edge of 173km Vertregt crater. The largest crater of the moon is the South Pole-Aitken (or SPA) basin, which is 1,600 miles or 2,500 kilometers in diameter and with 8.1 miles (13 kilometers) in depth. SPECTRAL ANALYSIS OF VOLCANIC FEATURES IN AITKEN CRATER ON LUNAR FARSIDE. Aitken Basin is the largest preserved impact crater of the solar system. Data from NASA’s lunar spacecraft point to … One of the largest craters in the Solar System is on our Moon. Access to the crater floor will be difficult from an outpost on the crater rim. Also, traverses to other locations within the South Pole-Aitken Basin will often need to circumnavigate the crater.
