The region of Earth's atmosphere that lies between 65,000 and
325,000-350,000 feet (20 to 100km) above sea level, above where a
commercial airliner flies but below the realm of an orbiting
satellite. The area is of interest for military surveillance
purposes, as well as to commercial interests for communications.
Currently, craft that fly in near space are generally high altitude
balloons, blimps (non-rigid airships) and sounding rockets. It is
also the realm of an activity known as Amateur Radio High Altitude
(ARHAB) Ballooning. JP Aerospace are interested in this region for
their Airship to Orbit program.
