The United States and China are considering launching manned missions to Mars -- in 25 years. But Netherlands-based Mars One has a bold plan to land humans on Mars in 2027. Is the mission fueled by wishful thinking and unproven science -- or will private exploration get us there?
When Mars One invited citizens to journey to Mars, 200,000 people applied. The final 100 include a military jet pilot, an ER doctor, and an IT consultant -- all willing to leave their loved ones forever. They share a common dream -- and a willingness to endure almost unimaginable isolation.
The trek from earth to Mars is fraught with difficulties, from surviving radiation en route to landing in a space craft not yet designed. Mars One founder Bas Lansdorp attends the Mars Society Convention in Washington, DC, to debate the risks and rewards with scientists from around the world.
From a greenhouse in Holland to a desert landscape in Iceland, scientists are using the earth to tests ways to keep a Mars settlement alive and well. It's the ultimate survival challenge, requiring major innovations to find water, grow food and clean the air.
Mars One plans one-way missions to Mars; the goal is not simply to explore, but to colonize the red planet. A one-way trip saves billions and eliminates the risk of a return voyage. But can the crew survive in such utter isolation? Some candidates for the mission reflect on this challenge.
