Mar 29, 2024 · Billions of years ago, Mars was much wetter and probably warmer than it is today. Curiosity is getting a new look into that more Earth-like past as it drives along and eventually crosses the Gediz Vallis channel, a winding, snake-like feature that – from space, at least – appears to have been carved by an ancient river.
Mar 19, 2021 · But most of the water, a new study concludes, went down, sucked into the red planet’s rocks. And there it remains, trapped within minerals and salts. Indeed, as much as 99 percent of the water ...

Jezero is a shallow impact crater about 45 kilometers in diameter just north of the planet’s equator. The crater formed sometime between 3.7 billion and 4.1 billion years ago, in the solar system’s first billion years. It sits in an older and much larger impact basin known as Isidis. At Jezero’s western curve, an etched ancient riverbed gives way ...
Deltas mark standing, lasting bodies of water — stable locales that could support life. Plus, as a delta grows over time, it traps and preserves organic matter. Sand and silt deposited where a river hits a lake get layered into sedimentary material, building up a fan-shaped delta. “If you have any biological material that is trapped between that se...
As of early February, Perseverance has collected 18 samples, including bits of Mars debris and cores from rocks, and stored them on board in sealed capsules for eventual return to Earth. The samples come from the crater floor, delta front rocks and even the thin Martian atmosphere. In the final weeks of 2022 and the first weeks of 2023, the rover d...
Oct 18, 2016 · The young planet Mars would have had enough water to cover its entire surface in a liquid layer about 140-meters deep. But it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 kilometres. ESO/M. Kornmesser.
It is still trapped there. March 16 2021, by Robert Perkins. While it was previously suspected that most of Mars's water was lost to space, a significant portion—between 30 and 90 percent—has ...
Mar 16, 2021 · Billions of years ago, according to geological evidence, abundant water flowed across Mars and collected into pools, lakes, and deep oceans. New NASA-funded research shows a substantial quantity of its water – between 30 and 99% – is trapped within minerals in the planet’s crust, challenging the current theory that due to the Red Planet’s low gravity, its water escaped into space.

Aug 25, 2022 · August 25, 2022. In its first year exploring Jezero Crater on Mars, the Perseverance rover collected rock samples that scientists anticipate will provide a long-awaited timeline for the planet’s geologic and water history. They’ll just have to wait a decade to find out the answer, until the samples can be scooped up from the surface and ...
