Space travel may accelerate aging at the cellular level

A new study suggests that long-term human spaceflight triggers inflammaging — a process where the body's immune system becomes chronically inflamed, mirroring accelerated aging. The finding could reshape how space agencies design missions and raises questions about the long-term health costs of commercial space tourism and deep-space exploration programs.
