 * 1) This template is missing RADAR, a subsystem used by Cassini, several Venus missions and several other related missions. It would need to be added at the top for alphabetical reasons.
 * 2) Even though the mariner 4 and 5 used a helium magnetometer, it was a triaxial and not a helium vapor.
 * 3) Cassine-Huygins Magnetometer is both a triaxial (vector) and Helium (general field).
 * 4) IRIS (Infrared Interferometer Spectrometer and Radiometer) is both a radiometer and IR spectrometer.
 * 5) SPICAM, SPICAV and MASCS (MESSENGER Atmosphere and Spectometer Surface Composition) are both and Visible-IR and UV-visible spectometer. SPICAV has a special Infrared version of Radio Science (Radio Accultation) spectrometer that is designed to detect the interference of Venus's atmosphere as that satellite passes behind venus relative to the sun.
 * 6) ASPERA (Analyzer of Space Plasmas and Energetic Atoms) -3 and 4 are a Neutral Particle Imager (NPI), Neutral Particle Detector (NPD), Electron Spectrometer (ELS), Ion Mass Analyzer (IMA)
 * 7) SPS (Solar Plasma Spectrometer) is both a neutral particle and ion detector.
