    3 days ago · 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.

    Jan 26, 2022 · But two scientists studying data that MRO has accumulated at Mars over the last 15 years have found evidence that reduces that timeline significantly: Their research reveals signs of liquid water on the Red Planet as recently as 2 billion to 2.5 billion years ago, meaning water flowed there about a billion years longer than previous estimates.

    Oct 16, 2006 · During the evaporation they made sulphates, the second mineral that OMEGA detected. When even this stopped and the remaining water on Mars became permanently frozen, then the atmosphere gradually turned the soil red by creating the third mineral OMEGA detected, ferric oxide. Mars has been like this for thousands of millions of years.

    Mar 16, 2021 · The research challenges the current theory that the Red Planet's water escaped into space. The Caltech/JPL team found that around four billion years ago, Mars was home to enough water to have covered the whole planet in an ocean about 100 to 1,500 meters deep; a volume roughly equivalent to half of Earth's Atlantic Ocean.
