"Dennis Anthony Tito" is an United States/American engineer and multimillionaire, most widely known as the first space tourism/space tourist to fund his own trip into space. In mid-2001, he spent nearly eight days in orbit as a crew member of ISS EP-1, a visiting mission to the International Space Station. This mission was launched by the spacecraft Soyuz TM-32, and was landed by Soyuz TM-31.

Before I flew to space, I had no idea how comfortable it would be. I think if a lot of people know what I know now there would be a huge demand.

I've been shelling out food and doing rather menial tasks to assist the crew and give them more time for their other work.
