NASA\u2019s Perseverance Rover Finds Buried Ancient River Delta on Mars
\n——————————-
\nNASA\u2019s Perseverance rover has discovered a buried ancient river delta beneath the surface of Mars, giving some of the oldest evidence yet that water once flowed on the Red Planet.<\/p>\n
Using its ground\u2011penetrating radar instrument, scientists mapped layered sediments and geological structures deep under the surface of Jezero Crater\u2014a site believed to have hosted a lake billions of years ago. The radar data show delta\u2011like formations dating back about 3.7 to 4.2 billion years, indicating long\u2011lasting water flow into the crater.<\/p>\n
Researchers say the find strengthens evidence that Mars once had a warmer, wetter climate capable of supporting environments that could preserve clues about past life. The results are based on data collected by Perseverance\u2019s RIMFAX radar between September 2023 and February 2024.<\/p>\n
Since landing in 2021, Perseverance has been exploring Jezero Crater, where scientists believe ancient river channels fed into a lake. Earlier research by the mission also identified rock samples that may contain potential biosignatures, though some minerals could form through non-biological processes.<\/p>\n","protected":false},"excerpt":{"rendered":"
