Editing Pioneer P-3 (section)

== On-board equipment ==
The scientific instruments consisted of an [[ion chamber]] and [[Geiger-Müller tube]] to measure total radiation flux, a proportional radiation counter telescope to measure high energy radiation, a [[scintillation counter]] to monitor low-energy radiation, a VLF receiver for natural radio waves, a transponder to study electron density, and part of the television facsimile system and flux-gate and search coil magnetometers mounted on the instrument platform. The television camera pointed through a small hole in the sphere between two of the solar panel mounts. The micrometeorite detector was mounted on the sphere as well. The total mass of the science package including electronics and power supply was 55&nbsp;kg.<ref name="nssdc">{{cite web|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=PIONX |title=NSSDC Master Catalog: Spacecraft Pioneer P-3 |website=NASA |access-date=May 18, 2025}}</ref>
