Explorer 17 was a US satellite that was successfully launched on April 3, 1963 as part of the Explorer program . The satellite was also known as Atmosphere Explorer-A (AE-A).
begin
The 185 kg satellite was launched on April 3, 1963 at 1:55 a.m. UTC with a Delta B rocket from the LC-17 launch pad at Cape Canaveral Air Force Station .
mission
The aim of the mission was to explore the upper layers of the earth's atmosphere. The instruments were sealed so that external influences from the earth's atmosphere did not impair the research results.
Instruments
Four manometers for measuring the neutron density , two spectrometers for determining the particle concentration and two Langmuir probes for measuring the ion concentration and the electron temperature were carried along .
Due to the failure of the batteries on July 10, 1963, only three of the four manometers could be used. While both probes continued to work, one of the spectrometers failed, the other only worked intermittently.
Whereabouts of the satellite
After 1,325 days, the lowering of the orbit was initiated on November 24, 1966 so that the satellite could burn up in the earth's atmosphere.
