   2 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. NASA/GSFC. About one-fifth of Mars was once underwater, raising the prospects for life. Although the surface of Mars is presently cold and dry, plenty of evidence suggests ...

   Oct 25, 2022 · Just like Earth, Mars likely got its water from asteroids and comets that bombarded its surface. Conditions may have been right for the red planet to be habitable from 4.1 to 3 billion years ago. During that time, life could have taken hold in global oceans, rivers, and lakes. Liquid water may have flowed even longer, up until about 2 billion ...

   Why is water on Mars important?

   • Water on Mars also has important implications for research areas at beyond the work of the Astrobiology Program. Even if life no longer lives on Mars, or never existed in the first place, water could still prove vital to future life on Mars in the form of human colonies on the red planet.

   Why is Martian water important?

   • The locations of Martian water are good places to search for past or even present life. Additionally, since it takes supply ships several months to travel between Earth and Mars, it behooves Martian astronauts to know where to find water that can be converted to rocket fuel, air, and drinking water.

   Did liquid water last flow on Mars?

   • Furthermore, there is plenty of evidence that liquid water formed vast oceans on Mars in the distant past, carving valleys and other surface features. But no one knows when water last flowed on the Red Planet's surface, or whether it still does. Why do the scientists now think there could be liquid water on the surface of Mars?

   Why is Mars so arid?

   • Right now, the surface of Mars is now extremely arid because the air is too thin for liquid water to last for long. The red planet’s atmospheric pressure is just roughly 1/100th of Earth’s and in such thin air water easily boils. However, dark, narrow lines on martian slopes hint that water could run down these formations regularly.
