Screams Australian Newspaper, The Herald Sun.
Well, let's see, shall we?
First of all, what is space?
The Fédération Aéronautique Internationale has established the Kármán line at an altitude of 100 kilometres (62 mi) as a working definition for the boundary between aeronautics and astronautics.
The United States designates people who travel above an altitude of 50 miles (80 km) as astronauts.
NASA's mission control uses 76 miles (122 km) as their re-entry altitude, which roughly marks the boundary where atmospheric drag becomes noticeable, (depending on the ballistic coefficient of the vehicle), thus leading shuttles to switch from steering with thrusters to maneuvering with air surfaces.
