Russian astronomer Vladimir Surdin named deep ravines on Mars as promising locations for future human landings. According to him, some areas of the Martian crust are up to 10 km deep and could provide additional protection from radiation. In addition, water in a frozen state might have been preserved there.
On Mars, there is a ravine in the Martian crust with a depth of up to 10 kilometers. Our Everest would be hidden in it. It could be a very promising place for a landing. The landing itself on Mars is not a very simple matter; the atmosphere there is rarefied, and parachutes work poorly. But the deeper you go, the denser the atmosphere, and when you land with a parachute in a ravine, it is denser there, and the landing is softer.
A senior researcher at the P. K. Sternberg State Astronomical Institute previously reported that an astronaut could receive a radiation dose of 80 rem during a flight to Mars. This is 16 times the permissible annual dose for an atomic power plant employee.
The astronomer noted that in the past, Mars was rich in liquid water, as evidenced by the preserved traces of riverbeds. Currently, water on the planet is either in the form of ice in the polar regions or beneath the surface as permafrost. Water preserved in Martian ravines, after necessary purification, could potentially be used for domestic needs.
