Chandrayaan-3 rover lands in oldest crater where ‘no other mission has gone’; S.Vijayan says “shows how the moon evolved”

Chandrayaan 3: India’s lunar mission landed in one of the oldest craters on the Moon, scientists said on Saturday. The crater where “no other mission” has reached is 3.85 billion years old, scientists say.

Scientists at the Indian Physical Research Laboratory and Indian Space Research Organization (ISRO) in Ahmedabad claimed that the crater was formed in the Nectaric period, 3.5 billion years ago.

‘No other missions have gone’

According to S Vijayan, associate professor at the Planetary Sciences Division of the Physical Research Laboratory, the mission’s Pragyan rover has gone to a place on the Moon that no other mission has visited.

“The Chandrayaan-3 landing site is a unique geological environment that has not been reached by other missions. Images of the mission. Pragian Rover They are the first in situ of the Moon at this latitude. They reveal how the Moon evolved,” Vijayan said, PTI reported.

Chandrayaan 3: How it landed in a crater

The researchers said a crater is created when an asteroid hits the surface of a larger body, displacing material known as ejecta.

The mission’s Pragyan rover images are the first images of the Moon at this latitude.

Images of the Moon have revealed that half of a crater is buried under ejecta from the South Pole’s Aitken Basin, the largest and most prominent impact basin on the planet. the moon.

An impact basin is defined as a large, complex crater with a diameter greater than 300 km, while a normal crater is less than 300 km in diameter. In this case, Chandrayaan-3 was found to have landed inside a crater approximately 160 km wide, appearing in the images as a nearly semi-circular structure.

“In addition, near the landing site, ejecta or material ‘thrown’ from another impact crater further away were observed; images captured by the Pragyan rover revealed that material of the same nature was present at the landing site,” Vijayan said. , mentioned a PTI report.

On August 23, 2023, Chandrayaan-3 made a soft landing at the south pole of the moon. The Government of India named the landing site as “Shiv Shakti Point”.
