Preserving Voyager's Legacy: Image Calibration and Geometry Reconstruction

Grant #: NNX10AP34G
Senior Scientist: Mark Showalter

 

The Voyager flybys remain our best source of data for the Uranus and Neptune systems, and provide key reference points for continuing studies of Jupiter and Saturn. However, because the Voyager mission pre-dates NASA's focus on archiving, the data sets remain difficult to use. We propose to modernize the Voyager data sets by (a) producing calibrated and geometrically corrected versions of all the images; (b) generating accurate, continuous "C kernels" describing the pointing of the instruments during each Voyager flyby; and (c) using this information to generate detailed geometric indices describing the contents of the Voyager images and spectra. The resulting volumes of derived products will be delivered to the Planetary Data System. This work will ensure that the Voyager data sets remain easily usable by the scientific community for many decades to come.
