NASA has planned to build a Starshade to look for Alien Planets. Starshade exoplanet-hunting missions may be technologically daunting.
Scientists did not expect to find much water ice on Mars which is likely the third largest water reservoir on Mars.
“We didn’t expect to find this much water ice on Mars,” lead author Stefano Nerozzi, a doctoral student in geology at the University of Texas Institute for Geophysics, said in a statement released by the American Geophysical Union, which published the new research. “That likely makes it the third largest water reservoir on Mars after the polar ice caps.”
According space.com “That is a lot of water. And the sheer amount of water ice in the area is backed up by a second study done by an overlapping team of scientists. That research used gravitational data about Mars collated by NASA from several of its missions to the Red Planet. But by this technique, too, the region comes up chock-full of water ice — enough that if you melted it down and spread it evenly around the planet, it would flood Mars by about 5 feet (1.5 meters)”.
“Understanding how much water was available globally versus what’s trapped in the poles is important if you’re going to have liquid water on Mars,” Nerozzi said. “You can have all the right conditions for life, but if most of the water is locked up at the poles, then it becomes difficult to have sufficient amounts of liquid water near the equator.”
The research was published on May 22 in the journal Geophysical Research Letters.
