The human body, adapted for Earth ’s gravity, begins to deteriorate rapidly in space.

Microgravity, radiation, and psychological isolation can lead to severe physical and mental deterioration.

To extend human survival in space, researchers are exploring various technologies to counteract the challenges of microgravity and radiation.

Axpe notes that challenges like bone loss, radiation exposure, and cognitive decline will need to be addressed before longer missions can be attempted. With current capabilities, humanity’s longest continuous stay in space—437 days aboard the Mir space station, achieved by Russian cosmonaut Valeri Polyakov —stands as a testament to human resilience. However, as Axpe cautions, “Missions longer than this would push the limits of human endurance.”.
