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.


Dust Storms Linked to Gas Escape from Mars Atmosphere

Dust Storms Linked to Gas Escape from Mars Atmosphere

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.


Flowing Sand, Not Water, Source of Some Recurring Dark Martian Surface Streaks

Flowing Sand, Not Water, Source of Some Recurring Dark Martian Surface Streaks

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.


Steep Slopes on Mars Reveal Structure of Buried Ice

Steep Slopes on Mars Reveal Structure of Buried Ice

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?

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.


Mars' Atmosphere Protected From The Solar Wind

Mars' Atmosphere Protected From The Solar Wind

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.

Recurring Martian Streaks: Flowing Sand, Not Water?

Recurring Martian Streaks: Flowing Sand, Not Water?

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.
