Live or travel Tuesday They will be a dream come true for researchers who will not give up until they reach it. However, they are not just focused on one construction task Space rocket There is ample facility to carry Astronauts, But everything that travels includes: where to sleep and take care of your health.
Being without is real Spacecraft You can not finish Mission to Mars Or any other target on the outside Earth, However, another basic area is that your crew is comfortable enough and with all the necessary equipment because, according to some estimates, the trip will last more than nine months.
In such a way, so the Astronaut Physical Health They should be kept as long as they are in space, they should have a place to sleep properly, i.e. that place should take care of their eyes.
Researchers have found that astronauts’ vision is significantly reduced after returning to Earth. This led to the discovery that zero gravity affects their vision.
As stated in it BBC, Discovered by NASA Lack of gravity Contributes to starting astronauts Vision problems, Because it does Body fluids crush the eyelids.
This evidence compares favorably with that of more than half of the astronauts who were at least six months old International Space Station (ISS). Some had difficulty reading or needed help completing tests.
It turns out Zero gravity Body fluids accumulate in the head, causing the eyelid to become under more pressure, leading to a condition Without Or also called Nerve-eye syndrome Associated with astronauts affecting the optic nerve and causing visual impairment.
One of these cases was recorded in 2005 by astronaut John Phillips, who arrived at the International Space Station with a 20/20 view (correct), but after a six-month journey he returned to Earth with a 20/100 view.
Thus, they are a concern Travel to Mars, Which can be considerably longer, can severely affect the eyes of your astronauts.
In this sense, astronauts have developed a space bed plan that helps maintain their visual health. Oddly enough, it was not intended for glasses, helmets or anything else, but a sleeping bag.
Although astronauts need to sleep comfortably, now it is important for them to maintain visual health, which is why they are trying to solve the problem in a bag that creates a pressure difference.
Its design is peculiar because it is tied at the waist and hides the astronaut’s legs to create different pressure than other parts of the body; That way, The fluid is drawn to the legs And not to the head.
This project is still in development because they want to polish it first, to give its best result to the astronauts trying to go into space. Although the current goal is to care for the eyes, they want it to help others Common diseases of astronauts Similar to atrial fibrillation.
