India’s Chandrayaan-3 mission continues to make groundbreaking discoveries after its successful mission ended on the Moon in 2023.
The data beamed back by the Pragyan rover from the Moon’s south polar region has now led to the discovery of an ancient crater.
The Pragyan rover has discovered an ancient, 160-kilometre-wide buried crater near its landing site. The findings have been published in the latest issue of Science Direct by scientists from the Physical Research Laboratory, Ahmedabad.
This significant find occurred as the Pragyan rover traversed the highland terrain at its landing site, approximately 350 kilometers from the South Pole-Aitken basin, the largest and oldest impact basin on the lunar surface.
The crater is believed to have formed before the creation of the South Pole-Aitken basin, making it one of the Moon’s oldest geological structures. Due to the crater’s age, it was mostly buried by debris from later impacts, particularly from the South Pole-Aitken event, and has been degraded over time.
Images taken by the Pragyan rover’s navigation and optical high-resolution cameras revealed the structure of this ancient crater, offering vital clues about the Moon’s geological history.
The crater’s discovery provides scientists with a rare opportunity to study deeply buried lunar material that dates back to some of the earliest impacts on the Moon.
