If one is venturing to the final frontier, it would be nice to know where it actually begins. Space has a definition – it is that point where the earth’s atmosphere officially ends and the vacuum of space officially begins. In aerodynamic terms, it is that point where there is no longer any lift on aerodynamic structures – such as the wings of aircraft.
NASA has a true need to know where this is for the purposes of piloting the Space Shuttle – and their equations define the boundary layer at 62 miles and the shuttle’s performance is plenty good with this definition.
