Orbital View Of A Polar Avalanche On Mars

by Keith CowingOctober 20, 2024

This scarp at the edge of the North Polar layered deposits of Mars is the site of the most frequent frost avalanches seen by HiRISE.

This is an image of the rim that the Perseverance rover took on sol 383 (March 19th, 2022) when it was traversing the crater floor. Dox Castle is located at the top of the image in the far ground. NASA/JPL-Caltech/ASU

Mars Perseverance Astrobiology Rover Heads Toward Dox Castle

by Keith CowingSeptember 25, 2024September 25, 2024

The Perseverance rover is reaching new heights as it ascends the rim of Jezero crater (over 300 meters in elevation higher than the original landing site)! The rover is now […]

Astrobiology Droid Perseverance Is At The Base of Jezero Crater’s Rim

by Keith CowingSeptember 13, 2024September 13, 2024

The view looks northwest from the southern edge of the crater. A blue icon shows Perseverance’s general location as of Aug. 14, 2024, the 1,238th Martian day, or sol, of […]

NASA’s Perseverance rover puts its robotic arm to work around a rocky outcrop called “Skinner Ridge” in Mars’ Jezero Crater. Composed of multiple images, this mosaic shows layered sedimentary rocks in the face of a cliff in the delta, as well as one of the locations where the rover abraded a circular patch to analyze a rock’s composition.

Rocks from Mars’ Jezero Crater, Which Likely Predate Life On Earth, Contain Signs Of Water

by Keith CowingAugust 15, 2024August 15, 2024

In a new study appearing today in the journal AGU Advances, scientists at MIT and NASA report that seven rock samples collected along the “fan front” of Mars’ Jezero Crater […]

Multiple Overspill Flood Channels From Young Craters Require Surface Melting And Hundreds Of Meters Of Mid-latitude Ice Late In Mars History

by Keith CowingJuly 23, 2024July 22, 2024

Mars’ tadpole craters are small, young craters whose crater rims are incised by one or more exit breaches but lack visible inlets.

Characterization of Aqueous Alteration and Formation of Salty Exposures at Ius Chasma, Mars

by Keith CowingJuly 21, 2024July 7, 2024

Intriguing outcrops in Ius Chasma provide a window into past aqueous processes in Valles Marineris, Mars. Hydrous sulfate minerals are abundant throughout this region, but one area in Ius Chasma […]
