Can the bodies of astronauts survive Mars missions?

Travelling into space changes the structure of kidneys, with galactic radiation causing damage that could potentially put human missions to Mars at risk, new research suggests.

Spaceflight is known to cause a number of changes in astronauts’ bodies, and as more people venture into space, understanding the health risks associated with space exploration is key for the preparation of long-duration, lunar, and potentially Martian missions, experts say.

Despite the findings in relation to kidneys, researchers suggest that short-duration space flights pose no significant health risks to private astronauts.
