As we all know, space is very different from the world we live in. There oxygen, water, food It is very difficult to meet even basic needs such as…

But the most important is oxygen right?

First of all, the multi-layered lower and upper bodies of astronaut suits protect them from harmful cosmic radiation.

It also provides them with a pressurized atmosphere while helping to maintain their body temperature. In fact, in space, just like on Earth, there are three basic things: Food, water and oxygen are needed. However, these are limited there.

Astronauts make sure they eat and drink water before they take off. Because they definitely want to drink water in the coming hours, they fill the drinking bag in their clothing with water. This water bag can be adjusted to your own wishes It can be 0.6 l or 0.9 l.

Inside the helmet there is a tube with a valve that comes out of the drinks bag. It extends close to the mouth. This valve opens automatically when the astronaut draws in water. Astronauts also take fruit bars with them.

The fruit bar is wrapped in edible rice paper and placed in a sleeve near the neck. The upper end also extends close to the mouth.

The two oxygen tanks in the astronauts’ backpacks allow a total of 6.5 to 8 hours of extravehicular activity. In fact, this number varies depending on the person’s metabolism, due to the amount of oxygen consumed It differs for everyone.

In other words, the length of time astronauts can survive in their spacesuits depends on the amount of oxygen their suits contain. Only available clothing 6.5 to 8 hours makes space exploration possible.

If astronauts still wish to continue extravehicular activities after this period, they must return to the spacecraft and refill their oxygen tanks. The record for the longest spacewalk was achieved by performing maintenance work on the ISS. spent 8 hours and 56 minutes Owned by Susan Helms and Jim Voss.
