4 days ago · Plate tectonics and other fundamental geological activity on Earth are linked with its oceans and on chemically-bound water in the mantle, and understanding the history of water on Mars could help reveal how it influenced the red planet’s geology.

Aug 12, 2024 · Scientists have discovered a reservoir of liquid water on Mars - deep in the rocky outer crust of the planet. The findings come from a new analysis of data from Nasa’s Mars Insight Lander, which...

Aug 18, 2018 · Liquid water appears to flow from some steep, relatively warm slopes on the Martian surface. Features known as recurring slope lineae (RSL) were first identified in 2011 in images taken by the...

Dec 14, 2023 · After 1,000 days on the Martian surface, the Perseverance rover has collected samples that reveal the history of water within Jezero Crater.

Feb 25, 2025 · The ochre color is characteristic of iron-rich ferrihydrite, a mineral that provides crucial insights into ancient water activity and environmental conditions on Mars. The fine-powder mixture consists of ferrihydrite and ground basalt with particles less than one micrometer in size (1/100th diameter of a human hair) (Sample scale: 1 inch across).

Jan 31, 2025 · The existence of water on Mars has long been a subject of curiosity and debate. A recently published study presents compelling evidence of ancient “wave ripples” in rocks that were shaped by Martian water and winds billions of years ago.

Oct 25, 2022 · Mars used to have oceans, lakes, and rivers. Where did the water go, how much is left, and how can we use it for science and exploration?

Mar 18, 2025 · Starting in the 1940s, astronomers were able to make measurements that began to tell us about the actual nature of the Mars environment. When the first spacecraft flew by Mars in 1965, we determined that the atmospheric pressure was only around half a dozen millibars, and the average temperature was 50 degrees Celsius below freezing. That demonstrated that liquid water could not be stable; if ...

Mar 29, 2024 · NASA’s Curiosity rover has begun exploring a new region of Mars, one that could reveal more about when liquid water disappeared once and for all from the Red Planet’s surface. Billions of years ago, Mars was much wetter and probably warmer than it is today.

Sep 9, 2024 · While planetary science researchers have theorized that water might exist in a variety of settings on Mars, and reported features indicating water once flowed across its surface, NASA’s InSight lander has provided new data that indicate large …
