Indeed, if this were to happen to you in reality, your body would swell up to double its usual volume, something that happens because the water in the tissues vaporizes due to the lack of pressure. However, you would not explode: the skin is very strong and does not tear just like that.

What if you don’t have a suit on the Moon?
It will swell up quite a bit, maybe even to twice its normal size, but it won’t burst as its skin is very elastic. Your blood will not boil. You will, of course, be in an immense amount of pain and your blood circulation will be hampered. Don’t worry too much, this will be for a very short time.
What consequences would it have to go out on the lunar surface without a space suit?
If someone gets out of a spacecraft (such as the International Space Station) or walks in a place with little or no atmosphere (such as the Moon or Mars) without wearing a space suit, the following would happen: The person would lose consciousness in about 15 seconds, due to lack of oxygen.
What happens if you go to space without a suit?
Any exposed liquid in our body will begin to vaporize. Then the surfaces of the tongue and eyes will boil. Without air in the lungs, the blood will stop sending oxygen to the brain. It will be about 15 seconds or so before we pass out.
How long does a person last in space without a suit?
Due to the absence of breathable air, an unsuited person in space would lose consciousness in about 15 seconds. But he would still be alive, at least a few more minutes, before he suffocated to death.

How long can you survive in space?
The duration varies, but it has rarely lasted more than 72 hours, after which the body adjusts to the new environment. On Earth, our bodies automatically react to gravity, maintaining stable posture and locomotion.
What happens if a person takes off his helmet in space?
In less than 15 seconds, the astronaut loses consciousness due to the lack of oxygen in the blood that circulates through the brain and his body is swollen, ‘boiling’, with bubbles in the blood, gas like body fluids and his heart still beating while floats in the inclement space.
What happens to a man in space?
What would happen to the human body after dying in space
First of all, the gravity could be different or even practically non-existent, so the stage of livor mortis would not occur. On the other hand, the muscles themselves would harden due to the cessation of bodily functions.
Why do astronauts wear special suits?
Why is it necessary for the astronaut to wear a space suit? The suit protects the astronaut from extreme temperatures. They contain oxygen so that the astronaut can breathe in the vacuum of space. It also contains water to drink during spacewalks.
What happens to dead bodies in space?
A different decomposition process
The lack of gravity when floating in space would prevent blood from pooling. Inside a space suit, rigor mortis would still occur, since it is the end of bodily functions.
Why does a spacesuit have to be inflated?
A spacesuit must perform several functions in order for its occupant to remain comfortable and safe. It must provide: A stable internal pressure. This can be less than the atmospheric pressure of the earth, and therefore it is not normally necessary to carry nitrogen in the suit.
What clothes do astronauts wear in space?
The official name of the spacesuits used during spacewalks is Extravehicular Mobility Unit (EMU), referring to the fact that these are not just a simple suit, but a whole set of systems that allow mobility. of the person in places outside the…
What are astronauts’ space suits like?
The lower part covers the astronaut’s legs and feet. It should be noted that the flexible parts of the suit are made of several layers of material that perform different functions, from keeping oxygen inside the suit to protecting it from the impact of space dust.
What items do astronauts use in space?
A fan ensures that the oxygen circulates, and there is a tank that contains the refrigerated water that circulates through the suit that the astronauts wear close to the body, and that maintains the body temperature in the cold environment of space.
How many men have died in space?
From its inception to 2003, there were 22 cosmonaut and astronaut casualties in the Soviet (now Russian) and American space programs. The following list shows the names of those explorers who lost their lives, the year and the missions in which they participated.
How cold is it in space?
However, the further you go into interstellar space, the colder it becomes, hovering around 2.7 kelvins, close to absolute zero, which is -273.15 degrees Celsius. The temperature in space is really cold.
How long does it take for an astronaut to return to Earth?
But if the idea is to make a round trip, according to NASA you will need to spend three to four months on the red planet before flying back to Earth for another nine months, so the total journey would take not less than 21 months.
What happens if an astronaut takes off his helmet on the Moon?
Then the astronaut would be left floating in space, swollen and with the blood boiling, but with the heart still beating.
What is there instead of air in space?
This is so because there is no air in space: it is a vacuum. Sound waves cannot travel through a vacuum. ‘Outer space’ begins 100 km away from Earth, where the shell of air that envelops our planet disappears.
What do astronauts do with their clothes?
In general, they wear the clothes for three to four days and then throw them away with other waste: this waste does not end up in space but is evacuated from the ISS to Earth with each rotation of astronauts. They then disintegrate when they enter the atmosphere, according to NASA.
How long does oxygen last in a spacesuit?
Finally, each astronaut carried a life support system that provided cooling water, power, a communication system, and the oxygen needed to spend four hours outside the lunar module without refueling.
How might the change in pressure affect astronauts when they travel to space if they were not wearing space suits?
If an astronaut were to take off his suit, his body would be subjected to a fairly sudden change in pressure. What’s more, there is no oxygen in space, so they couldn’t breathe without their helmet.
What temperature can a spacesuit withstand?
Without the presence of Earth’s atmosphere to filter sunlight, the side of the spacesuit facing the sun can reach temperatures of up to 121°C, the other side, exposed to darkness, can reach -157°C.
How does the body decompose in space?
Can a body decompose on the Moon? Not completely. If an astronaut were to die on the Moon with his sealed suit on, the bacteria in his gut would begin to multiply out of control and cause the body to swell from gas, mostly carbon dioxide, methane, and hydrogen sulfide.
How does a dead person decompose?
Decomposition begins at the moment of death, caused by two factors: autolysis, the breakdown of tissues by the body’s own enzymes and chemicals, and putrefaction, the breakdown of tissues by bacteria.
