The crew of the “Union” held on the ISS for 6 days, during which the astronauts conducted scientific experiments, and tourist Tito was engaged in Photo and video shooting, kept a diary and picked up groceries for Breakfast, lunch and dinner for everybody on the ISS. On may 6 Russian cosmonauts Dennis returned to Earth.
Immediately after landing, the first space tourist said he was in heaven, and that is going to publish a book about his time in space. For flight in earth, orbiculate paid the Federal space Agency of Russia of 20 million US dollars. Continue reading
