Solar Instruments
The Plasma and Suprathermal Ion Composition (PLASTIC) portion of STEREO is a time-of-flight mass spectrometer that samples the in situ solar wind and suprathermal ions (including interstellar pickup ions), providing measurements of kinetic properties and composition. There are identical PLASTIC instruments on each STEREO spacecraft (STEREO A and STEREO B).
