To book a space trip, a deposit of $5 million is required. Sergey Brin, one of the founders of Google, will also become their customer.
Google co-founder Sergey Brin has invested $5 million with Space Adventures as a deposit to secure a seat on Russia's Soyuz spacecraft in the future, with the total amount for the actual spaceflight expected to be around $35 million.
