Russian cosmonauts and their NASA colleagues, as well as two space tourists, are taking an exam in Star City near Moscow on Tuesday. The results will decide whoâ€™ll make up the crew of the next mission to the ISS.
One of the space tourists, Charles Simonyi, is hoping to travel to the International Space Station for the second time and thus become the first one to do so twice. Simonyi went to the spacecraft in April 2007.
He is a member of the main crew, which also includes Russian cosmonaut Gennady Padalka and American astronaut Michael Barratt.
The back-up crew consists of Russian cosmonaut Maksim Surayev, American astronaut Jeffrey Williams and space tourist Esther Dyson. The 57-year-old journalist may become the second female tourist to travel to the ISS, after Anousheh Ansari in 2006.
