Celebrating NASA’s Mars Reconnaissance Orbiter’s 20th Anniversary: Crater Near Sirenum Fossae

NASA’s Mars Reconnaissance Orbiter captured a detailed 2015 image of a relatively fresh crater near Sirenum Fossae, featuring a sharp rim, well‑preserved ejecta, steep gullied slopes, and possible recurring slope lineae. The crater is monitored for changes, and MRO’s 20‑year mission has gathered water‑history data to aid future astronauts.
