PAET, an entry probe experiment in the earth's atmosphere.

Description of the instrumentation of a probe designed for atmospheric studies on other planets and designated PAET. The probe was launched on June 20, 1971, near Bermuda in a trial experiment for measurements of the structure and composition of the terrestrial atmosphere. The instrumentation included accelerometers, pressure and temperature sensors, a mass spectrometer, and a radiometer. The measurements, carried out during the descent of the probe from an altitude of 90 km into the sea, were a success.
