Where DOES Space Begin?

Post by Wade Hampton III » Fri Feb 22, 2019 5:19 pm

There's just one little problem...many de-mark space at 62 miles (100 km). That
boundary, nicknamed the Karman line, is often treated as edict. A database of
90 million orbital paths collected from 60 years of spaceflight, searching for
the lowest approaches that were sustainable for multiple orbits. For circular
orbits, that line falls around 75 miles (120 km); satellites on elliptical
orbits can swing down to 50 miles (80 km). Those elliptical orbits make leaving
the entryway to space at 62 miles (100 km) clunky, to say the least.
