From NASA’s Moon to Mars program to Elon Musk’s ambitious plan to send a million people to Mars by 2050, the race is on to get human feet on the red planet. With increasingly sophisticated rockets and robotics, the technological challenges standing in the way of this goal are fast being eroded.
But there might be a different issue which hampers plans to take people off-planet and send them out to explore the rest of the solar system. Strange things happen to the human body in space, and we’re going to need to find ways to address these medical issues if we want to be able to send astronauts on long-duration missions like the several years that a Mars mission might require.
Digital Trends spoke to University College London cardiologist Dr. Rohin Francis, who has performed studies into space medicine, about how human bodies respond to long-term habitation of the space environment and what that might mean for manned missions to Mars.
