What would happen if an astronaut took off his diving suit on Mars

Although there is still time for humans to set foot on the red planet, the truth is that we have more and more data on the great enigmas of Mars. On February 18, 2021, NASA’s Mars 2020 rover successfully landed in Jezero crater., with the aim of looking for signs of ancient microbial life to explore the past habitability of this planet.

However, we still need to see the astronauts dressed in their suits roaming the surface of this planet. But why do they need the diving suit? What would happen if it was taken away?

The suit protects from temperatures and solar radiation

The diving suit is the clothing used by astronauts for spacewalks, as it protects them from extreme temperatures or radiation and provides the oxygen necessary for them to breathe in space. Also, “the suit brings water to drink and prevents astronauts from being damaged by small pieces of space dust,” they explain at NASA. They even incorporate visors “to protect the astronauts’ eyes from intense sunlight.“.

In the case of Mars, the MEDA system (Mars Environmental Dynamics Analyzer) aboard the Perseverance rover has sent the first weather report from the Jezero crater. Thus, the data show that the temperature on the planet’s surface It was -20 ° C when the tool started measuring and dropped to -25.6 ° C in just 30 minutes. Furthermore, the thin atmosphere of Mars does not protect from solar radiation and lacks oxygen.

The human being “would evaporate instantly”

In such a way that if a human being took off his diving suit on the surface of the red planet “I would not die from radiation or cold, I would do it before because it would start to boil. Basically it would evaporate instantly “, the researcher at the astrobiology center and one of the participants of the Perseverance mission explained in statements collected by Telecinco Jorge Pla-Garcia.

This would happen because as there is no liquid water “the pressure is so low on Mars that any drop of water immediately sublimates and becomes a gaseous state without passing through liquid “. The researcher details that until relatively recently it was thought that the water from Mars “had been lost to space”, but “it has been discovered that a good part of it infiltrated 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 caps, but all of it is in the solid phase and a little in the gaseous phase.” Therefore, it is “impossible that there is liquid water”, concludes.
