When scientists wish to study the atmosphere above us, many different means of transportation are used: Aircraft - Maximum altitude, regular aircraft: 10 km. High altitude aircraft: 25 km. Sounding rockets - From 2-3 km to 1000 km. 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 …

A copy of the probe was lifted by balloon to an altitude of 35 km and dropped, to see if the heat shields and the parachutes worked as planned.
