"The Juno Project shall characterize the UV auroral emissions over all science orbits"
Characterization includes imaging and spectroscopy of the UV auroral emissions. Imaging the auroral morphology allows mapping of the emission distribution to Jovian coordinates and provides context for Juno's locally-measured particles and fields measurements in the larger polar magnetosphere. Spectroscopy allows determination of the mean energy of the precipitating electrons at the top of Jupiter's atmosphere. Magnetic field models provide the connection between Juno and its field line footprint in the Jovian aurora.
Besides characterizing the auroral emissions, our UVS goals are to:
- Map the precipitating electrons energies (using differential absorption by CH4)
- Observe the spacecraft footprint region to compare UVS data with particle and waves data
- Look for structure and variability in low-latitude airglow emissions
