- To determine the scattering properties of the lower planetary atmospheres.
- To determine the distribution of constituents with height.
- To determine the extent and distribution of hydrogen corona of the planets and satellites.
- To investigate night airglow and auroral activity.
- To determine the UV scattering properties and optical depths of planetary rings.
- To search for emissions from the rings and from any ring "atmosphere."
Instrument Characteristics
The Voyager 1 Ultraviolet Spectrometer (UVS) is a compact Wadsworth mounted objective grating spectrometer that covers the wavelength range of 0.0535 to 0.1702 micron for Voyager 1 and 0.0513 to 0.1680 micron for the Voyager 2. A mechanical 'collimator’ defines the main 'airglow' field-of-view (FOV) of 0.10 x 0.87 degrees full-width-half-maximum (FWHM). Light passing through the collimator strikes the concave diffraction grating at near normal incidence. The grating disperses and focuses light onto a 1-d array detector that records individual photoevents. An auxiliary field-of-view for solar occultation experiments is offset 20 degrees from the airglow field by a small mirror near the front of the collimator. Using this 'occultation port', UVS can view the Sun without pointing the main field, and those of other coaligned instruments, directly at the Sun. The occultation field is 0.25 x 0.87 degrees. A sunshade prevents illumination of the main entrance aperture by the sun during occultation observations.
