Detailed explanation-1: -Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity.
Detailed explanation-2: -Astronauts need to consume more food to offset the decrease in their energy intake due to microgravity, small spaces, insufficient exercise, and shortened circadian rhythm changes. However, the poor palatability of processed and packaged space food causes the astronauts to eat less.
Detailed explanation-3: -A microgravity environment leads to changes in fluid distribution, muscle loading, and altered signaling pathways. Some basic changes include alterations in blood pressure and the quantity of blood that is pumped by the heart with each beat.
Detailed explanation-4: -Radiation. The first hazard of a human mission to Mars is also the most difficult to visualize because, well, space radiation is invisible to the human eye. Isolation and confinement. Distance from Earth. Gravity (or lack thereof) Hostile/closed environments. 08-May-2019
