Researchers are struggling with our limitation in space flight our own bodies.


he human body has evolved to flourish on the surface of the Earth. What occurs whenever you take such an earthbound body and place it in the weightlessness of space? . Things get weird. Astronauts commonly report vision upon their return home, maybe since the eyeball changes form in space and cells enclosing the optic nerves become bloated. Without the constant tug of gravitation, bones become more fragile and muscle atrophy. Now there is impulse to send humans into space further and longer than we have ever been before, subjecting our bodies into even more of the strange environment.

The White House has tasked NASA with the mission of returning to the moon by the year 2024. The plan entails a lunar gateway, a space station that orbits the moon. These efforts can lay the groundwork for a possible crewed mission on Mars, which might put astronauts in space and on the red planet for ages. And there are much more far-fetched fantasies incubating. Tech titans Jeff Bezos and Elon Musk have stressed that humans ought to become interplanetary species. We’re going to construct a road to distance, Bezos said at a latest event unveiling a moon lander design for his rocket company.

And after that amazing things will happen. Each one of these grand ideas, possible assignments, and fantasies of a long term human presence in space rely on one thing: our feeble human bodies can manage it. However, the reality is, no one knows what happens to a body when it spends over a year in distance. What we do have is many quite significant, untested, and unresolved questions on what happens to the human body in space, and also how we may protect the brave individuals who venture out there. Listed below are 3 of the greatest unknowns and the largest risks.
