Story summary

Space travel negatively affects human stem cells, accelerating aging and impairing function.
Studies monitored bone marrow stem cells during SpaceX missions to the International Space Station, lasting 30 to 45 days.
Stem cells in space exhibited reduced cell formation and increased DNA damage due to microgravity and radiation.
Genetic resilience may influence individual responses to stem cell dysfunction.
Prolonged exposure risks include DNA damage, cancer, and immune system problems, highlighting the need for protective measures.
