The Edge of Space
Posted: Sun Aug 05, 2018 11:11 pm
If astrophysicist Jonathan McDowell's calculations are correct, the
cosmic boundary where the laws of airspace suddenly give way to the
laws of orbital space might be a lot closer than we think — a full
12 miles closer than previous estimates suggest. "The argument about
where the atmosphere ends and space begins predates the launch of the
first Sputnik," McDowell, an astrophysicist at the Harvard-Smithsonian
Center for Astrophysics, wrotein his new paper, which will appear in
the October issue of the journal Acta Astronautica. "The most widely
accepted boundary is the so-called Karman Line, nowadays usually set
to be 100 km (62 miles) altitude."
