Oct 9, 2025 by News Staff

Roughly 4.3 billion years ago, when our Solar System was still in its infancy, a giant asteroid slammed into the far side of the Moon, blasting an enormous crater referred to as the South Pole-Aitken basin. This impact feature is the largest crater on the Moon, spanning more than 1,200 miles north to south, and 1,000 miles east to west. The oblong shape of the basin is the result of a glancing blow rather than a head-on impact. Upending conventional...

This image from NASA’s Mars Reconnaissance Orbiter shows Jezero Crater on Mars, the landing site for NASA’s Mars 2020 mission. On ancient Mars, water carved channels and transported sediments to form fans and deltas within lake basins. Examination of spectral data acquired from orbit show that some of these sediments have minerals that indicate chemical alteration by water. Here in Jezero Crater delta, sediments contain clays and carbonates. Image credit: NASA / JPL-Caltech / MSSS / JHU-APL.
