Challenges with interstellar travel – Radiation, gravity and temperature. Discussion on the challenges of interstellar travel specifically as it relates to radiation, low gravity, and temperature. Radiation is a major problem to any space crew. Exposure to ionizing radiation can cause diseases and cancer. Low gravity can cause muscle and bone density loss over time. And the extreme low temperature of space requires massive energy and protection. These are challenges, some daunting, others not so much, that stand between us and the stars.
