Sergey Brin, Google’s co-founder, plans to enjoy himself in the year 2011 by taking a trip to the International Space Station. The millionaire already deposited $5 million in order to make sure that his seat will not be given away.

The full story behind the news involves a Virginia-based company, Space Adventures which facilitates space rides to the International Space Station for wealthy customers on Russian Soyuz rockets. The company plans on buying a Soyuz flight in 2011, with the possibility of buying more, and Brin’s deposit could also be considered an investment in the company’s future plans and development.

The plan involves a trip with a Soyuz rocket which will visit the International Space Station and offer a brand new experience for its passengers.

Brin said in a statement presented by the New York Times that he is a big believer in the exploration development and commercial potential of the space frontier and that he is very excited about the possibility of going into space.

 Space Adventures is responsible so far for five such vacations and not everyone is thrilled about the prospects of this activity. Vitaly Lopota, the president of Energia, the Russian spacecraft company, recently expressed his thoughts about the space tourism business, saying that the I.S.S. was built for serving the need of the people on Earth and not for serving the need of amusement.

So far, even though the exact numbers haven’t been disclosed, the space trips’ costs add up to over $20 million.
