When astronauts return to Earth from space, they can experience a range of health and physical problems after landing – a result of life without gravity.
During flights that last up to six months, astronauts can experience difficulties with balance, muscle weakness, and cardiovascular deconditioning, according to NASA. Although the Inspiration4 flight only lasted three days, the four returning astronauts will also have a health check-up.
It is unclear what exactly these health tests might consist of. Health researchers who worked with Inspiration4 said the astronauts should do some experiments that measure their sense of balance – without swaying and moving between sitting and standing positions.
They will also take a series of tests that measure their cognitive performance – the same ones they took before take off and during each orbit.
An overview of NASA’s medical needs from the time astronauts flew on the space shuttles gives an idea of what doctors look for in astronauts returning from shorter flights in space.
For flights that are less than 30 days, doctors examine the astronauts’ vital signs and look for neurological problems, as well as chest and lung problems.
Headache, dizziness, dizziness, and weakness are some of the neurological symptoms that doctors check for in astronauts.
Returning astronauts will also check the function of their eyes and ask them to perform a series of tasks including: touching their nose with their finger, getting up from a chair, lifting one leg and hopping, walking in a straight line, and then turning and turning in Heel-toe walking.
If the doctors find enough problems, they can decide that an astronaut needs to do additional tests.
