Microsoft developer Charles Simonyi, the world's fifth space tourist, returned to earth this weekend from a two-week junket to the International Space Station. 

Simonyi, who led the development of Microsoft's Word and Excel applications, paid $25-million for the trip.
The space tourist returned with a Russian-US crew, landing in Kazakhstan in the central Asian steppe.
The return flight from the International Space Station, 350km above the Earth, took just three hours.
