Curious Mars

Recently in the Mars Category

Mars was characterized by cataclysmic groundwater-sourced surface flooding that formed large outflow channels and that may have altered the climate for extensive periods during the Hesperian era. In particular, it has been speculated that such events could have induced significant rainfall and caused the formation of late-stage valley networks.

The presence of water on ancient Mars is a paradox. There's plenty of geographical evidence that rivers periodically flowed across the planet's surface.

Recent findings suggest Mars may have been a clement environment for the emergence of life, and may even have compared favorably to Earth in this regard.

NASA's Curiosity rover is climbing a layered Martian mountain and finding evidence of how ancient lakes and wet underground environments changed, billions of years ago, creating more diverse chemical environments that affected their favorability for microbial life.

Two geo-scientists at Arizona State University have made a discovery among hot springs in Chile that may spur scientists to revisit a location on Mars explored several years ago by NASA's Spirit rover.

A strangely shaped depression on Mars could be a new place to look for signs of life on the Red Planet, according to a University of Texas at Austin-led study.

Build-up of relatively young (<∼3.6 Ga) deltas and alluvial fans on Mars required lakes to persist for >3 Kyr (assuming dilute flow), but the watersheds' little-weathered soils indicate a climate history that was >99% dry.

The evidence for abundant liquid water on early Mars despite the faint young Sun is a long-standing problem in planetary research.

Small-crater counts on Mars light-toned sedimentary rock are often inconsistent with any isochron; these data are usually plotted then ignored.

A PhD student from the University of Leicester is helping to shed light on life on Mars by exploring similar environments on Earth -- including an underground salt mine in North Yorkshire.
