The Real Problem With Space Travel

Space is a hostile environment for humans. While we are able to survive in microgravity for extended periods, the longer we stay in space, the higher the likelihood of causing irreparable damage to the human body. Humans in space suffer exposure to cosmic radiation, muscle and bone loss, and even things like their eyeballs changing shape! Psychological stress is also likely to be a major concern. For stays of about 6 months on the ISS, there appears to be no long-term issues with proper rehabilitation, once back on earth. However, with trips to Mars looking to take about 3 years, we need some serious scientific development before humans are able to travel there safely. In the first part of this 2-part video, we speak to NASA scientist, Dr Dorit Donoviel PhD and Astronaut Physician, Dr Mike Barratt , about the impact space has on a human body, to understand what we need to overcome before we can get to Mars.
