Although humans still have time to set foot on this red planet, the truth is that we have more and more data about the big mystery of Mars. On February 18, 2021, NASA’s “Mars 2020” Mars rover successfully landed in Jezero Crater., The purpose is to find signs of ancient microorganisms to explore the past habitability of the planet.
however, We still need to see astronauts in their suits The spacecraft traverses the surface of the planet. But why do they need diving suits? What happens if you take it away?
Diving suits are clothes used by astronauts Used in spacewalks, because it can protect them from extreme temperatures or radiation and provide them with the oxygen they need to breathe in space. In addition, “this suit can drink water and prevent astronauts from being destroyed by a small piece of space dust”, Explained in NASA. They are even equipped with sun visors, “to protect the eyes of astronauts from strong sunlight.“.
As far as Mars is concerned MEDA system (Mars Environmental Dynamics Analyzer) has been installed on the Hengxin rover The first weather report of Jezero crater.Therefore, the data shows the temperature of the planet’s surface The tool started measuring at -20°C and dropped to -25.6°C in just 30 minutes. In addition, the thin atmosphere of Mars cannot withstand solar radiation and lacks oxygen.
In this way, if one takes off the diving suit on the surface of the red planet “I will not die of radiation or cold, I will do it because it will start to boil. Basically it will evaporate immediately”, Explained in the statement collected by Telecinco A researcher from the Center for Astrobiology and one of the participants of the Perseverance Project, Jorge Pragarcia.
The reason for this is that because there is no liquid water, “the pressure on Mars is so low that Any drop of water will immediately sublimate and become a gas, instead of passing through the liquid.”. The researchers detailed that until recently, people thought that Martian water “has been lost to space,” but “a large part of it has been found to have penetrated and passed underground in the form of water ice.
In this sense, “There is a lot of water on Mars hidden under the CO2 ice of the polar cap, but all of it is in the solid phase and rarely in the gas phase.” and so, He concluded, “There can be no liquid water.”
