When astronauts return to Earth from space, they may experience a host of health and physical problems after landing as a result of living without gravity.
During flights of up to six months, astronauts may experience difficulties with balance, muscle weakness, and cardiovascular deconditioning. NASA. Although the Inspiration4 flight only lasted three days, all four returning astronauts will undergo health screenings.
It’s unclear what exactly this health screening might consist of. The health researchers working with Inspiration4 said they will conduct some experiments measuring astronauts’ sense of balance—standing without swaying and moving between sitting and standing positions.
They will also run a series of tests that measure their cognitive performance, which is the same as they do before takeoff and during orbit.
