how many miles up is space
The AP reports that organizers claimed the ship crossed the official 62-mile-high border of space. Why does space officially begin 62 miles above the Earth? Because 62 miles is about 100 kilometers, and 100 is a nice round number. The creators of the prize settled on 100 kilometers because it's the figure used by the World Air Sports Federation (FAI), the organization that maintains the aeronautical record book and keeps track of achievements in flying.
