Audi introduced its concept car Audi AI: Trail at the IAA 2019. The car is special because it combines futuristic design with autonomous driving, electric mobility.
We think each of us has thought about the question as what is the largest crater on Earth’s moon?
One of the largest craters in our Solar System is on the Moon and it is called the South Pole-Aitken (SPA) basin. It is 2,500 km (1,600 mi) in diameter and 13 km (8.1 mi) deep.
A new research says that the basin may contain an enormous chunk of metal that’s larger than Hawaii’s Big Island.
The largest crater is the largest, oldest, and deepest basin recognized on the Moon. It was named for two features on opposing sides: the crater Aitken on the northern end and the lunar south pole at the other end.
The outer rim of this basin can be seen from Earth as a huge chain of mountains located on the Moon’s southern limb, sometimes informally called “Leibnitz mountains”.
You know that on 3 January 2019, the Chang’e 4, a Chinese spacecraft, landed in the basin, specifically within a crater called Von Kármán. In May 2019, scientists declared that a large mass of material had been identified deep within the crater.
According to Wikipedia “Simulations of near vertical impacts show that the bolide ought to have excavated vast amounts of mantle materials from depths as great as 200 km below the surface. However, observations thus far do not favor a mantle composition for this basin and crustal thickness maps seem to indicate the presence of about 10 kilometers of crustal materials beneath this basin’s floor”.
“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,” said lead author Peter B. James.
