While reading Red Mars by Kim Stanley Robinson in 1999 Shaun realized that people would go to Mars in his lifetime, and he decided he wanted to be part of that. Since then he has been an active member of a variety of space enthusiast groups, including the Mars Society and Mars Society Australia. Shaun is also the founder of the Mars Settlement Research Organization. His research has included how to make air and steel on Mars, Martian timekeeping systems, terraforming and more, and he has given numerous presentations at conferences in Australia and the United States. For the past 1.5 years he has been developing a robust and affordable humans-to-Mars mission architecture and a plan to establish an International Mars Research Station, which is now available as a book. Shaun has agreed to answer any questions you may have. As usual, ask as many as you'd like, but please, one per post.
