Explorer 32, also known as Atmospheric Explorer-B or AE-B, was a NASA direct-measurement upper-atmosphere satellite launched on May 25, 1966. Its neutral and ion mass spectrometers, electrostatic probes, and density gauges measured ion and neutral composition, electron concentration and temperature, and thermospheric structure across altitude, latitude, local time, and solar activity during its roughly ten-month science mission.
