An American billionaire who paid $25 million for a 13-day trip to outer space returned to Earth on Saturday in a space capsule that also carried a cosmonaut and an American astronaut, making a soft landing on the Kazakh steppe.

The capsule carrying Charles Simonyi, a Hungarian-born software engineer who helped develop Microsoft Word and Excel, arrived after a more than three-hour return trip from the orbital station, a spokesman said at Mission Control outside Moscow, describing the touchdown as a "soft landing."
