An American space tourist has landed back on Earth after a 10-day holiday at the International Space Station. Computer games millionaire Richard Garriott paid about £17 million to join astronauts on board the Russian Soyuz TMA-13 spacecraft. During his out-of-this-world adventure, he took photos of Earth to see how its surface has changed in the past 35 years, when his dad was last in space. Garriott was following in the spacesteps of his dad, Owen Garriott, who spent two months taking photos of Earth from the International Space Station back in 1973.
