Creating a database and GUI to identify Rosetta images of Comet 67P/Churyumov-Gerasimenko

The OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) instrument [1–2] onboard the European Space Agency’s Rosetta mission [3] comprise both a wide angle camera (WAC) and a narrow angle camera (NAC). These cameras have collected nearly 100,000 images of 67P/Churyumov-Gerasimenko over the ~2 year active mission. Owing to the complex requirements on the Rosetta mission to accommodate and collect data for nearly a dozen instruments, the imaging opportunities for OSIRIS varied throughout the mission. This, coupled with the irregular shape of the comet nucleus, has resulted in a dataset that can be difficult to navigate and creates challenges when attempting to identify images of given regions from this scientifically rich dataset.

To this end, we are developing a database of the OSIRIS images that will be accessed via a 3D graphical interface. The user will be able to select regions of interest (ROI) on the comet surface, and apply any of a range of filters, such as viewing and illumination geometries, range and date. The query will then return and display a list of images that overlap with the user’s ROI and meet the filtering criteria. Our prototype package includes OSIRIS NAC images, but will be expanded to include OSIRIS WAC images as well as data from other remote sensing instruments, such MIRO (Microwave Instrument for the Rosetta Orbiter) [4] and VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) [5].
