Why can not you take off your spacesuit on Mars?

If you ever find yourself among the brave astronauts who set out to colonize the Red Planet, you should know a simple survival rule on Mars: do not undress your spacesuit! Even if you really want it! Due to the fact that the conditions on Mars are fundamentally different from those on Earth, the possible consequences can become irreversible and even lead to your death.

The extremely diluted Martian atmosphere contains virtually no mixture of oxygen and nitrogen, which is crucial for us. After several attempts to take at least one breath, there is a risk that you die of suffocation. In addition, under severe Martian conditions, there is an extremely unpleasant human phenomenon: all of the water entering Mars begins to boil at 0.5 degrees Celsius. In other words, without a space suit on Mars you risk not only losing oxygen, but also simply "cooking".

First, such a destructive process affects the soft tissues of your body, which can multiply because of the lack of atmospheric pressure. As a result, such a high expansion can lead to extensive rupture of blood vessels and capillaries.

Atmosphere on Mars

Despite the unpleasant Martian property, which manifests itself in the form of boiling water at low pressure, the planet is almost always very cold weather. The average daytime temperature on Mars is -50 degrees, but on long Martian nights, the temperature often drops to -120 degrees.

Despite the cold, your body can maintain a more or less pleasant temperature for some time, because the heat due to the lack of atmosphere leaves the body only slowly. In other words, for some time you can at least reassure yourself that you will not have time to freeze on Mars right away. Well, you will have other problems. Massive.

Problems with the atmosphere and especially with the ozone layer threaten the daredevil, who nevertheless dares to take off his space suit, with the strongest radiation exposure. I think many have heard of the possible consequences of such an event, and unfortunately it does not do any good.

In any case, you have about one and a half minutes to get into the oxygen atmosphere. In this positive scenario, you can get rid of minor injuries (eg, temporary hypoxia blindness). If this does not work, the pressure in the circuit can drop so much after 90 seconds that a revival simply is no longer possible.

And how long would you survive without a spacesuit on Mars? Let's discuss this in telegram chat.
