Data presented in the new paper, co-authored by Caltech graduate student Eva Scheller, suggests anywhere from 30% to 99% of the original water on Mars has been retained. At the same time, the authors say the prevailing theory about Martian water leaking ou

These results were presented on March 15 at the 52nd Lunar and Planetary Science Conference. We know the Red Planet was once covered in flowing water, as evidenced by the remnants of deep ocean basins, lakes, rushing rivers, and even stupendously huge tsunamis. The total volume of water that used to exist on the ancient Martian surface is estimated at half the total volume of the Atlantic Ocean, which is hardly a trivial amount. Such was the case billions of years ago, but most of this water appears to be gone, and the small amount thats left has retreated to the polar ice caps and possibly the odd subterranean reservoir. But as Scheller explained in a NASA statement, the atmospheric escape of Martian water doesnt fully explain the data that we have for how much water actually once existed on Mars.

Mars has two small, oddly shaped moons. Phobos is the larger one at 17 miles 27 km across, while Deimos is just 9 miles 14.5 km in diameter. Using its Mastcam, Curiosity recently captured the moons passing in front of the Sun. The NASA rover has done this before, but these new eclipse images, released by NASA yesterday, are among the best weve seen to date. Deimos passing in front of the Sun.

The Deimos eclipse happened on March 17, 2019. Technically speaking, its not an eclipse owing to the small size of the moon and how little of the Sun is actually being covered. This is more of a transit, similar to how distant exoplanets move across their host star, and are subsequently spotted from our vantage point on Earth. The shadow of Phobos dark
