        "Description": "This data set contains Version 3.1 final archival set of hourly averaged solar wind data from the Plasma Analyzer of the Pioneer 10 mission. It includes plasma bulk parameters in ASCII format: bulk velocity, proton number density, proton temperature, and flow angles. This is the same data set as NSSDC ID SPHE-00066 or 72-012A-13L, which is in binary format.",
