Detector, Plasma Wave, OGO-5

Summary
This is a flight spare for the sensor system carried on the Orbiting Geophysical Observatory V (OGO-V) satellite designed to measure the energy characteristics in the radiation belts surrounding the Earth. The long boom carries a set of special antennas which sent their signal to a small pre-amplifier attached to the base of the boom. From there the signal went into the main body amplifier (Catalogue #19860561000). This apparatus was manufactured by the Space and Technology Group of TRW; the firm donated it to the Museum in February 1985.
OGO-V was the fifth in a series of standardized spacecraft capable of performing many related geophysical experiments during the middle 1960s. The sensor formed part of an experiment that measured the electrostatic and electromagnetic plasma properties of the region of space from the upper ionosphere to the solar wind. The flight model of the plasma wave detector was placed in orbit from Cape Kennedy on March 4, 1968. Data from this instrument provided the first evidence for the shock wave observed in the solar wind as it encounters the Earth's magnetic field, the so-called bow shock.

Slender metal boom topped by two orthogonally connected ring antennas; two sets of perpendicular rod antennas ending in rings are attached at almost even intervals below; wiring harness comes out close to bottom.
Full view of a long brown stick with three interconnected circles at the top. Two sticks extend horizontally out of the main stick with golden rings at their ends. Silver machinery is at the bottom of the stick.
