Are bodies floating in space eternal or decaying?

Corruption requires several conditions. Anaerobic bacteria and aerobic bacteria must develop into colonies at a certain temperature, and then corruption creates conditions. What else is the refrigerator for? Of course, space is not a refrigerator, but there are worse conditions than a refrigerator. So let's see how the body will return to his home in space.

You should be able to see that the one in the above picture must be played by a living person, and it was taken in a studio on the ground. After all, the posture is unnatural and still moving, so it must be alive ... but even if it is really a corpse, it will still move in the way it left the mother ship, because there is no air resistance in space, and only a little movement posture will last until a certain constraint condition appears!

The background of the dead astronaut is Mars, which is a scene in the mission to mars. If a corpse floats in the orbit of Mars, it will basically meet the following conditions: floating, slightly swollen, and the surface seems to have a slight burning sensation ... Let's see why this happens and the future development trend!

First, floating is certain, and this need not be explained too much!

Second, after slight swelling and pressure loss, gas can't be discharged through circulation during the internal and external pressure balance process, so there will be swelling on the skin, which should not rupture except the wound, or slightly rupture! Because the human body itself is a relatively high-intensity individual, and there will be atmospheric pressure difference after pressure loss, there will be no scenes of pressure loss and explosion in many less rigorous science fiction films!

Third, the slight burning marks on the surface are due to the strong direct sunlight near the earth's orbit. For example, there must be sun protection measures in the equatorial region, and there is no atmospheric barrier in space. Sunlight is not affected, which directly burns the skin. It is certain that it will burn or turn slightly black after exposure!

Is that all? How will the future develop?

First, the early stage of anaerobic bacteria corruption in the body will continue, because there is still a lot of pressure inside the body, but with the balance between others and the outside world through various channels, this corruption will gradually stop!

Second, if it is not exposed to the sun or the heat does not reach the area, it will gradually freeze. Space is two extreme worlds. Because there is no atmospheric temperature balance, the direct sunlight temperature is as high as 100 degrees (or refer to the highest temperature on the moon), and the coldest temperature can reach-0/00 degrees, which makes the body freeze with the decrease of the temperature in the shadow area!

Third, continue to develop. The body will sublimate in the sun and the epidermis will dehydrate. After dehydration, the skin will gradually become particles, which will spread or float around with the movement. This is another form of "corruption", a physical process. The organic matter in sunlight gradually disappears, and finally only dry matter remains. .....

So will the body go on like this forever? Probably not, depending on his orbit, such as near-earth orbit, then with the resistance of the thin atmosphere, the orbit will gradually decrease and eventually re-enter the atmosphere. According to the structural strength and size of his body, he should not reach the ground!

If it is in orbit around the sun, then maybe it will remain forever until it captures the influence of a planet or an asteroid impacts and changes its orbit, and may fall into a planet or even the sun eventually!
