Plasma Probe (Ames Research Center) (failed)


Mission Name: Pioneer-E
Principal Investigator:Dr. John H. Wolfe


A truncated hemispherical analyzer is used to study the directional intensity of the electrons and positive ions in the solar wind. Positive ions are studied in 30 energy/charge windows from 150 to 15,000 v. Electrons are studied in 14 energy/charge windows from 12 to 1000 v. Incident particles are observed in 23 sectors of 2-13/16 deg each in the equatorial plane of the spacecraft. Seventeen of these sectors are contiguous and bracket the solar direction. The remainder are widely spaced. Particles incident above and/or below the spacecraft equatorial plane are observed in three sectors bracketing this plane. The rocket failed at launch, thus terminating the mission.
