Explorer 22

Explorer 22 (known as S-66B pre-launch; also called BE-B or Beacon Explorer-B) was a small NASA ionospheric research satellite launched 9 October 1964, part of NASA's Explorers Program. It was instrumented with an electrostatic probe, four radio beacons for ionospheric research, a passive laser tracking reflector, and two radio beacons for Doppler navigation experiments. Its objective was to provide enhanced geodetic measurements of the Earth as well as data on the total electron content in the Earth's atmosphere and in the satellite's immediate vicinity.
