An American space tourist, astronaut and cosmonaut returned to Earth from the International Space Station (ISS) Wednesday aboard a Russian Soyuz spacecraft.

The Soyuz capsule landed at 11:16 a.m. Moscow time in Kazakhstan's steppe, a source in the Russian Federation's Mission Control Center told Itar-Tass. Aboard were Russian cosmonaut Yuri Lonchakov, astronaut Michael Fincke of the U.S. space agency NASA, and software billionaire Charles Simonyi.

Lonchakov and Fincke had spent 178 days in the ISS. They were replaced by cosmonaut Gennady Padalka and astronaut Michael Barratt, who along with Simonyi, traveled to the ISS on March 26 aboard the same spacecraft.

Simonyi spent 11 days in orbit paying $35 million for the space adventure.
