Water on Mars: The Story So Far | News | Astrobiology
4 天之前 · NASA scientists have determined that a primitive ocean on Mars held more water than Earth's Arctic Ocean and that the red planet has lost 87 percent of that water to space. Credit: NASA/GSFC. For decades, abundant research has suggested that rivers, lakes and seas once covered Mars billions of years ago.
Mars water: Liquid water reservoirs found under Martian crust - BBC
2024年8月12日 · 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...
Water on Mars - Wikipedia
Mars contains water, though mostly as permafrost. As top surface layer water appears readily visible at some places, such as the polar Korolev Crater. Almost all water on Mars today exists as polar permafrost ice, though it also exists in small quantities as vapor in the atmosphere. [1]
Scientists find oceans of water on Mars. It’s just too deep to tap.
2024年8月12日 · Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water — enough to fill oceans on the planet’s surface.

2024年8月12日 · Data from a retired NASA mission has revealed evidence of an underground reservoir of water deep beneath the surface of Mars, according to new research. A team of scientists estimates that...
NASA Confirms Evidence That Liquid Water Flows on Today’s Mars
2015年9月28日 · New findings from NASA’s Mars Reconnaissance Orbiter (MRO) provide the strongest evidence yet that liquid water flows intermittently on present-day Mars. Using an imaging spectrometer on MRO, researchers detected signatures of hydrated minerals on slopes where mysterious streaks are seen on the Red Planet.
A 4.45 billion-year-old crystal from Mars reveals the planet had water …
3 天之前 · If Mars was once habitable, some amount of water was required. We studied the mineral zircon in a meteorite from Mars and found evidence that water was present when the zircon crystal formed 4.45 ...
NASA’s Curiosity Searches for New Clues About Mars’ Ancient Water
2024年3月29日 · 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.
Perseverance rover reveals new clues about water on Mars | CNN
2023年12月14日 · After spending 1,000 days on the Martian surface, NASA’s Perseverance rover has uncovered new details about the history of an ancient lake and river delta on the red planet.
The Oldest Evidence For Water on Mars Reveals It Was Extremely …
3 天之前 · "The emerging picture is that early Mars and Earth had something in common – both were wet. It is known from analysis of the oldest zircons on Earth that liquid water existed by at least 4.3 billion years ago. We now have evidence for water on Mars that is even older," geologist Aaron Cavosie of Curtin University in Australia told ScienceAlert.
