Rat study suggests Mars mission could scar astronauts' hearts
Original: Mars-bound astronauts could face years of heart scarring, rat study hints
A new study in rats suggests that prolonged exposure to deep-space radiation and microgravity could cause lasting scarring of heart tissue, with damage potentially persisting for years after a Mars mission ends. Researchers say the findings raise fresh concerns about the cardiovascular risks astronauts would face on long-duration spaceflight, and may inform protective measures for future crewed trips to the Red Planet.
Why now: New research highlights a previously underappreciated long-term health risk for astronauts planning multi-year Mars missions.
