Not content with his first astronautic experience, Ex-Microsofter billionaire Charles Simonyi is now training for a second trip to the International Space Station in Spring 2009. Simonyi will be the first repeat Space Adventures customer since the company began sending private citizens into the final frontier in 2001.
The last time he went (in 2007), Simonyi paid roughly $20 million to participate in a lower back muscle study, map the station’s radiation environment and test HD camera components. This time around, he’ll have to pay $30 million thanks to inflation and increased costs. [MSNBC]
