New research shows that dry ice blocks, not water or life, may be responsible for the mysterious gullies carved into Mars’ ...

The tests also revealed that the ditches only develop on dunes with very fine, evenly sized sand grains. Coarser or more jagged material prevents the burrowing motion, which could explain why the ...

Could ancient microbes still be hiding on Mars—preserved for millions of years in ice? A new NASA and Penn State study ...

Experiments show that biomolecules trapped in pure ice could withstand the harsh radiation of Mars for tens of millions of ...

"We have found a habitable environment," said John Grotzinger, project scientist for the Curiosity mission. "The water that was here was so benign and supportive of life that if a ...

Blocks of carbon dioxide ice appear to carve mysterious gullies on Mars as they melt down dune slopes and blast away sand.

CO₂ ice blocks on Mars may dig gullies as they slide and sublimate in the thin atmosphere. In lab experiments, scientists recreated these eerie, worm-like movements under Martian conditions. The ...

Frozen in time, ancient microbes or their remains could be found in Martian ice deposits during future missions to the red ...

SpaceX's upper-stage spacecraft made a soft, controlled landing on water at the end of its 11th test flight on Monday.

Analyses of its emissions using NASA’s Neil Gehrels Swift Observatory indicate that the interstellar comet probably has a ...

NASA's Curiosity rover has found evidence of water on ancient Mars with "rippled textures" and "landslide debris" in the ...

SpaceX launched its Starship megarocket on its fifth test of the year from Starbase, Texas, and 11th overall since 2023. Here's what happened.
