One of the Google’s co-founder, Sergey Brin, has allegedly booked a flight to the International Space Station. Brin will buy one of the two available seats on Space Adventures’ 2011 flight.

According to The New York Times, which broke the news in advance, Sergey Brin will make an official announcement on Wednesday.

The tourist space flights are operated by the Russian space agency together with US-based company Space Adventures and a price of a flight to the International Space Station aboard a Soyuz spacecraft is now somewhere around $30 million. Sergey Brin already made an investment of $5million into the company that will serve as a deposit on his future flight.

Until now there have been only five space tourists. The last space tourist was Charles Simonyi, 58, a Hungarian-American billionaire who flew to the ISS earlier this year. His predecessors are Denis Tito (2001) and Gregory Olsen (2005), both of the United States; Mark Shuttleworth of South Africa (2002) and the world's first female space tourist Anousheh Ansari, a U.S. citizen of Iranian origin, who flew to the ISS in 2006.

Space Adventures offers a variety of programs such as the availability for spaceflight missions to the International Space Station and around the moon, Zero-Gravity flights, cosmonaut training, spaceflight qualification programs and reservations on future suborbital spacecrafts.
The company's advisory board includes Apollo 11 moonwalker Buzz Aldrin, Shuttle astronauts Sam Durrance, Tom Jones, Byron Lichtenberg, Norm Thagard, Kathy Thornton, Pierre Thuot, Charles Walker, Skylab/Shuttle astronaut Owen Garriott and Russian cosmonaut Yuri Usachev.

This year it seems like Vladimir Gruzdev, a Russian politician and businessman, will made his trip to the ISS. Gruzdev is well-known for his appetite for extreme adventures and he took part in the Russian expedition Arktika 2007.
