The Aitken basin, on the south pole of the Moon, might hold a very dense object as revealed in new information coming out from NASA. It is believed the unusual sector might be the influence of a heavy metal asteroid impact that occurred millions of years ago.
NASA’s Gravity Recovery and Interior Laboratory (GRAIL) and Lunar Reconnaissance Orbiter endeavors have marked a miss match in topography and proceeded to investigate that Moon’s mass anomaly.
Peter B. James, a geoscientist at Baylor University in Texas and study lead author, had this to say: “Imagine taking a pile of metal five times larger than the Big Island of Hawaii and burying it underground. That’s roughly how much-unexpected mass we detected.”
The gravitational tug of the Moon was mapped on the NASA’s GRAIL mission, where two spaceships used one another to ping signals for more than a year.
Moon’s Mass Anomaly At Its South Pole Hints To An Ancient Metal Asteroid Impact
The dark side of the Moon, Aitken basin, the placeholder of the anomaly, features an enormous crater, measuring 2000 kilometers ( 1.240 miles ) across. Being the largest, in fact, believed to have been formed 4 million years ago.
“One of the explanations of this extra mass is that the metal from the asteroid that formed this crater is still embedded in the moon’s mantle,” Peter B. James adds.
Another theory that explains the existence of the Moon’s mass anomaly was posited by scientists. It states that due to the richness in oxides, the area was formed during the Moon’s tumultuous past when vast masses of magma flow cooled down and solidified.
The Moon’s mass anomaly concerning the satellite’s south pole, coming in at 300 km ( 186 miles ), is making scientists believe that the Moon’s interior needs to be solid as not to force the heavy mass into itself with gravitational forces.
