New Day for Longest-Working Mars Rover

NASA's Mars Exploration Rover Opportunity recorded the dawn of the rover's 4,999th Martian day, or sol, with its Panoramic Camera (Pancam) on Feb. 15, 2018, yielding this processed, approximately true-color scene.

NASA's Mars Exploration Rover Opportunity keeps providing surprises about the Red Planet, most recently with observations of possible "rock stripes."

New research published in Nature Astronomy seeks to understand how surface clay was formed on Mars despite its cold climate.

New Selfie From Curiosity Rover

A new self-portrait of NASA's Curiosity Mars rover shows the vehicle on Vera Rubin Ridge, which it has been investigating for the past several months.

A panoramic image that NASA's Curiosity Mars rover took from a mountainside ridge provides a sweeping vista of key sites visited since the rover's 2012 landing, and the towering surroundings.

Some Mars experts are eager and optimistic for a dust storm this year to grow so grand it darkens skies around the entire Red Planet.

Dark surface features previously considered evidence of subsurface water flow on Mars have now been interpreted as being the result of dry, granular flows, according to a Nature Geoscience paper.

Researchers using NASA's Mars Reconnaissance Orbiter (MRO) have found eight sites where thick deposits of ice beneath Mars' surface are exposed in faces of eroding slopes.

What Happened To Mars' Surface Water?

An international study co-led by SFU researcher Brendan Dyck has revealed that the sun may not have evaporated away all of Mars' surface water after all.

Despite the absence of a global Earth-like magnetic dipole, the Martian atmosphere is well protected from the effects of the solar wind on ion escape from the planet.

NASA's senior Mars rover, Opportunity, has just passed the shortest-daylight weeks of the long Martian year with its solar panels in encouragingly clean condition for entering a potential dust-storm season in 2018.

Dark features on Mars previously considered evidence for subsurface flowing of water are interpreted by new research as granular flows, where grains of sand and dust slip downhill to make dark streaks, rather than the ground being darkened by seeping water.

The sharp eye of the NASA/ESA Hubble Space Telescope captured the tiny moon Phobos during its orbital trek around Mars on 12 May 2016.

Color-discerning capabilities that NASA's Curiosity rover has been using on Mars since 2012 are proving particularly helpful on a mountainside ridge the rover is now climbing.

The Next Mars Rover Will Have 23 Eyes

When NASA's Mars Pathfinder touched down in 1997, it had five cameras: two on a mast that popped up from the lander, and three on NASA's first rover, Sojourner.

Curiosity Gets Ready To Drill Again

NASA's Mars rover Curiosity team is working to restore Curiosity's sample-drilling capability using new techniques. The latest development is a preparatory test on Mars.

Mars has an invisible magnetic "tail" that is twisted by interaction with the solar wind, according to new research using data from NASA's MAVEN spacecraft.

Layered Deposits in Uzboi Vallis on Mars

Layered deposits in Uzboi Vallis sometimes occur in alcoves along the valley and/or below where tributaries enter it.

A Closer Look at Holden Crater

Holden Crater in southern Margaritifer Terra displays a series of finely layered deposits on its floor (white and light purple in an enhanced color image).

Martian Prospecting From Orbit

The combination of morphological and topographic information from stereo images from NASA's Mars Reconnaissance Orbiter, as well as compositional data from near-infrared spectroscopy has been proven to be a powerful tool for understanding the geology of Mars.
