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

NASA/JPL-Caltech/Univ. of Arizona

NASA’s Mars Reconnaissance Orbiter (MRO) captures a detailed view of a relatively fresh crater in this image released on June 3, 2015. The crater has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. This crater is monitored for changes over time.

For 20 years, MRO has sought out the history of water on Mars with its science instruments.
