Could the remains of astronauts who died in the universe and crashed into other planets be the origin of life?

The courage to explore the unknown, is engraved in the DNA of human excellence, and exploration must be accompanied by sacrifice, it can be said that all the results of human exploration, are interwoven with blood and tears of lament.

In earth to explore the unknown, and in space to explore the unknown is the same. Compared to the conditions suitable for human activities on Earth, the problems faced in space exploration will be more, and usually more difficult.

This leads to the question: If an astronaut dies in space exploration and it is difficult to recover his remains with current technology, will his remains become the origin of life on other planets?

What happens to the remains after death

On Earth, after death, if not any treatment, then decay is the only destination of all Earth creature's corpses, this is mainly due to the body losing the regulation of the immune system, the body of microorganisms will proliferate, and then the body will be broken down into small molecules, rejoining the series of cycles of nature.

In space, astronauts live in the astronauts and spacecraft, both places can ensure that the astronaut's oxygen and pressure needs, the body's immune system can function normally, and the body's microbes will be able to coexist in harmony to reach a balance.

If the astronaut dies, the original harmonious symbiosis of microorganisms will lose regulation, at first, there will be a period of surge in the human body to the body's remaining material as a source of energy, followed by the decomposition of the body. But this growth will not last long, as changes in the environment will again inhibit their proliferation.

The biggest difference between spacecraft and spacesuits compared to the space environment is the gas, temperature, and pressure. Space is a near-vacuum, and if the suit is connected to the outside world when the astronaut dies, the water in his body will be rapidly evaporated.

Because there is no heat-conducting medium in the vacuum, the heat in the body can only be slowly radiated by radiation, so the astronaut's body will not be cooled very quickly, at this time the microbes can still survive in the body.

And because there is no atmosphere in the universe, direct sunlight on the remains of the body will have a strong heating effect, but also able to kill many microorganisms.

In this double baptism of ice and fire, it is difficult for microorganisms in the body to survive, and without the decomposition of microorganisms, the remains of astronauts will not decay as on Earth.

Homing of the remains

Nowadays, because of the limitations of technological capabilities, astronauts perform almost all missions are near-Earth missions, which means that they are not far from Earth, still in the gravitational range of the Earth.

If the astronauts were to die within this distance, then the remains would orbit the Earth under its gravity, become a "satellite" of the Earth, and then be slowly pulled into the Earth's atmosphere, in the violent friction with the atmosphere to become a dazzling meteor, just like the fate suffered by the dog Lycra.

In the early development of human spaceflight, to ensure the safety of astronauts, before the astronauts really into the universe, scientists have done many animal experiments, and the first mammal into the universe is a 3-year-old mixed-breed female dog called "Lycra".

On November 3, 1957, after more than 20 days of training, "Lanka" flew out of the atmosphere with Sputnik 2 and entered the universe.

Because the spacecraft does not have a setup insulation system, the only means of cooling is a small fan, in the heat and fear of attack, into the universe after only 5 hours, Lycra will lose all the vital signs.

April 4, 1958, "Sputnik 2" in 2570 revolutions around the Earth after crashing into the atmosphere, in the violent friction together with Lycra became a member of the natural cycle of the Earth.

In addition to being burned up in the atmosphere, the remains of the astronauts were also likely to be "burned up" by the sun's rays. Under the action of the sun's rays, charged particles will continue to bombard biological tissue, so biological tissue under the impact of the slow decomposition, and finally converted into small molecules dissipated in the universe.

If an astronaut dies while on a mission in outer space and his suit or spacecraft is intact, his remains will float around the universe until they are recaptured by the gravitational pull of a planet, as Earth's gravity cannot affect him.

It should be noted that even if the suit and spacecraft are well preserved after the electrical and life support systems stop working, the astronaut's remains will still be in extreme cold and most of the microorganisms in the body will be dormant or dead as a result.

If the planet where the remains were captured has an atmosphere similar to Earth's, then the remains will end up in the same atmosphere as the Earth, due to the violent friction was completely burned up, while if the planet does not have an atmosphere or an extremely thin atmosphere, the remains will probably fall directly to the surface of the planet.

Will the remains become the seed of life on the planet?

The human body contains a large amount of organic matter, which contains one of the most important components of life - amino acids.

But the mere presence of amino acids does not necessarily mean that life will emerge, because if life is a building, amino acids are only the cornerstone bricks of this building, and the bricks will not build a complex building by themselves without the help of external forces. Therefore, even if the remains fall to the surface of a planet, they will not necessarily give birth to live.

If the remains, by chance, fall into the planet's ocean, and the ocean and the existence of submarine hot springs, then the probability of breeding life is very high because the environment around the hot springs can greatly promote the synthesis of other essential substances for life.

As Louisiana State University microbiologist Gary King said in an interview with Astronomy magazine if human bodies landed on a planet that already had some essential molecules, the odds of life would skyrocket.

And his view also brings a thoughtful question: the origin of life on Earth, could it be because the corpse of some alien creature fell into the Earth?
