The first person to pay for visiting outer space is Dennis Tito. His one week trip to the International Space Station cost 20 million dollars, and was courtesy of the Russians. NASA wasn't thrilled.
The first man in space boarded the Russian spacecraft Vostok 1 in April 12, 1961 with a 50-50 chance of survival. The spacecraft orbited the earth for one hour and 48 minutes and returned successfully.
The American space shuttle is the most complex machine ever built. It is made up of 2.5 million parts and it's engines produced 44 million horsepower on takeoff. The space shuttle program closed on July 21, 2011, after having brought 3 millions pounds of cargo into space.
The International Space Station travels 253 miles (408km) above the earth at 17,100 (27,519km/h) miles per hour and completes a full circle of the earth every 90 minutes. Astronauts on board get to see a sunrise and sunset 16 times each day.
93 percent of all water on board the International Space Station is recycled. NASA has even installed a high tech water filter that turns urine into water. The US astronauts drink it, but the Russian astronauts refuse, although they don't mind handing over their urine to the Americans.
