The Instruments
Cameras
In terms of the cameras, the Europa Imaging System(EIS) will produce high-resolution and stereoscopic images of Europa, while also studying geologic activity. The Europa Thermal Emission Imaging System(E-THEMIS) will use infrared light to distinguish warmer regions of Europa where liquid water may be present.
Spectrometry
The Europa Ultraviolet Spectrograph(Europa-UVS) wil help determine the composition of Europa’s surface materials and atmospheric gas. The Mapping Imaging Spectrometer for Europa(MISE) will create maps detailing the distribution of salts, ices, and warmest hotspots on Europa which will aid scientists in understanding the geologic history of Europa.
Plasma and Magnetic Field
The Europa Clipper Magnetometer(ECM) will determine if Europa’s ocean exists and if it does it will measure the salinity and depth of it. The Plasma Instrument for Magnetic Sounding(PIMS) will distinguish distortions in the magnetic field of Europa which will reveal key information about Europa’s ocean.
Radar and Gravity
The Radar for Europa Assessment and Sounding: Ocean to Near-surface(REASON) will have an ice-penetrating radar probe for the suspected ocean on Europa and study the structure and thickness of the ice on Europa’s crust. Also, it will study the roughness, composition, and surface elevations.
Chemical Analysis
The Mass Spectrometer for Planetary Exploration/Europa(MASPEX) will analyze gasses in the atmosphere of Europa, how the ocean and surface exchange material, and how radiation affects compounds on the surface of Europa. The Surface Dust Analyzer(SUDA) will identify the area of origin and chemistry of the pieces of Europa’s surface that have been ejected into space by small meteorites. This will help scientists determine the salinity of Europa’s ocean.
