Satellites - Lowest altitude possible (due to air density): about 200 km.
One of the most interesting areas of study in recent years has been the ozone layer, at an altitude of about 25 - 35 km. A problem with studies of the ozon layer is the fact that it cannot be reached by means of planes or satellites. Using sounding rockets will transport the experiment to…
