The European Space Agency (ESA) has launched a surprising new picture of an icy crater on Mars, taken by the Trace Gas Orbiter. The Trace Gas Orbiter, a collaboration between ESA and Russian area company Roscosmos, primarily examines the gases in the martian atmosphere but in addition takes photos of the floor and acts as a communication hyperlink between landers and rovers on the floor and Earth.
This placing picture reveals a crater 2.5 miles huge close to Mars’s northern pole, within the Vastitas Borealis area:

The colour variations present the purple Martian soil contrasted with water ice contained in the crater.
“The crater is partially filled with water ice, which is also particularly predominant on its north-facing slopes that receive fewer hours of sunlight on average throughout the year,” ESA writes. “The darkish materials clearly seen on the crater rim – giving it a considerably scorched look – doubtless consists of volcanic supplies reminiscent of basalt.
“Most of the surrounding terrain is ice free, but has been shaped by ongoing aeolian processes. The streaks at the bottom right of the image are formed by winds that have removed the brighter iron oxide dust from the surface, exposing a slightly darker underlying substrate.”
Finding water on Mars is a giant problem for potential crewed missions there, as water is just too heavy to hold all the best way to Mars on a rocket. One possibility for future explorers is to seek out craters on the planet that include water ice, like this one or the well-known Korolev crater, which might be melted down and used for ingesting and for gas. However, most locations the place there may be ice on the floor of Mars are across the poles, and most missions need to go to the equatorial areas.
Another possibility is to look beneath the floor for ice, which is the plan of upcoming missions just like the Mars Ice Mapper. A last possibility could be to take hydrated minerals from the soil and bake them to launch the water they include.
