The brief
NASA and ESA scientists are researching the biological mechanisms of hibernation to assist astronauts traveling to Mars. The research focuses on how black bears reduce their heart rate from approximately 55 beats per minute to as few as 8 during hibernation while avoiding the muscle and bone loss typically associated with inactivity.
Coverage from Space Daily and The Guardian highlights the potential for humans to hibernate their way to Mars, while The Times of India notes that scientists are working to make this concept safe for human application. However, reports from srilanka.factcrescendo.com state that NASA is not currently preparing to put astronauts into hibernation.
Future developments depend on whether researchers can translate these biological tricks into a safe state for human use during deep-space travel.
