When South African computer specialist sold his company to Google, he had more than enough money to pay for his trip to the ISS, courtesy of Space Adventures.

Paying a whopping $20 million for his ride in 2002, Shuttleworth performed intricate experiments during his 10-day stay on the ISS- one of which was the first of its kind, and which involved investigating the effect of zero-gravity on the development of embryos and stem-cells.

One other important experiment involved investigating the possibility of crystallizing HIV proteins in conditions of weightlessness, hoping that when the proteins are subjected to X-rays, the image will reveal the exact nature of the HIV virus. Currently, these ongoing experiments are being managed by world-leading South Africa scientists in collaboration with Russian specialists in various space-related sciences.
