The most prolific space tourist is the Hungarian-born US-software billionaire Charles Simonyi (USA). Simonyi paid $25m (then £12.5 million) for his first trip on a Russian Soyuz rocket on 7 April 2007, the first stage of a 12-day visit to the International Space Station (ISS). Two years later, at the age of 60, Simonyi paid $35m (£24m) for a second voyage, also to the ISS, departing on 26 March 2009, returning to Earth 9 April 2009.
