According to his analyses of historical data, Virgin Galactic is right—space begins about 50 miles (80 kilometers) from the ground. Neither Blue Origin nor Virgin Galactic can put people into orbit around Earth, but the nature of orbits provides a useful way to understand this problem.

The U.S. military and NASA define space differently. According to them, space starts 12 miles below the Kármán Line, at 50 miles above Earth's surface. Pilots, mission specialists and civilians who cross this boundary are officially deemed astronauts.
