Pioneer 10 Trapped Radiation Detector 30-Minute Count Rate Summary

21 pulse-counting channels and averaged currents from a Cerenkov counter, electron scatter detector, and minimizing ionizing particle counter on the Pioneer 10 spacecraft. The ASCII data set contains 30-minute count rates and currents, spacecraft position and attitude data, and statistical and housekeeping data for mission cruise phases. This data was produced by the National Aeronautics and Space Administration and was last updated on the platform in March 2026.

Use Cases

• Modeling interplanetary radiation fluxes based on 30-minute count rates for multiple particle energy thresholds.
• Analyzing spacecraft exposure to energetic particles during cruise phases based on Cerenkov counter and electron scatter detector data.
• Correlating particle detection events with spacecraft position and attitude data mentioned in the description.

Strengths

• Data includes measurements from 21 distinct pulse-counting channels for different particle types and energy levels.
• Contains integrated spacecraft position and attitude data alongside the particle measurements.
• Produced by the authoritative source National Aeronautics and Space Administration.

Limitations

• The description notes that electrometer-based currents data are not reliable.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
