A Homesick Astronaut on Mars
Posted on 08/07/2013
Dr David Green, Lecturer in Human & Aerospace Physiology at King’s College London, was quoted in a Scientific American blog by Kelly Oakes about the problems that astronauts face when they can no longer see Earth.
Dr Green says: ‘The crewmembers who’ve been to the moon, they all say how disconcerting it was as they got further and further away from Earth. These guys knew that they were going to an object that wasn’t that far away. If you’re going to Mars, at some point the Earth is going to go to the size of a pin, and then you’ll lose sight. What that will do to somebody, who knows?’
Oakes’ blog asks questions about the ‘technological and physiological hurdles’ that need to be overcome before spaceflights to Mars become a reality.
