NASA has been able to shed some light on how the moon we see today evolved as it is. It was made possible by the Lunar Reconnaissance Orbiter (LRO). It is a NASA robotic spacecraft currently orbiting the Moon on a low 50 km polar mapping orbit. The LRO mission is a precursor to future manned missions to the Moon by NASA.
NASA has released two videos to celebrate the 1000th operational day of its Lunar Reconnaissance Orbiter. The first video named ‘Evolution of the Moon’, explains the likely origin of the Moon, starting around 4.5 billion years ago.
The Moon was formed as the result of a collision and later it slowly cooled. Meanwhile the cooling stage, it received a series of foreign object strikes of its own, including a massive impact on its south pole that formed the 2,500 km-wide South Pole-Aitken Basin.
This is currently known as one among the two largest proven impact basins in the solar system. Because the moon had not entirely cooled on the inside, magma began to seep through cracks caused by impacts.
Around one billion years ago, it’s thought that volcanic activity ended on the near side of the moon as the last of the large impacts made their mark on the surface. The moon continued to be battered by smaller impacts.
Scientists believe that the size of the rock ripped out of Earth by the impact was equivalent to Australasia. A region made up of Australia,New Zealand, New Guinea and neighboring islands.
As the solar system evolved through its orbit around the galactic core, there is invaluable information etched deep into the moon’s rock, not only providing information about the evolution of our own planet, but the evolution of our entire galaxy.
The information regarding every aspect of the moon is important as it may be the place where our future generations may reside due to the increased problems we are facing now such as population explosion and global warming.
Now here’s the video:
