Juno Mission


LPAP is actively involved in the NASA Juno mission

The Centre Spatial de Liege (CSL) contributed to the UVS spectrograph on board Juno

Prof Denis GRODENT is co-Investigator of the ultraviolet spectrograph UVS on board Juno. He is taking part to the analysis of the hyperspectral images of the auroral emissions of Jupiter. D. Grodent is also the Principal Investigator of the large size HST observation campaign in support to the Juno prime mission (HST GO-14634). The scientific description of this HST campaign may be found in this white paper.
Dr Bertrand BONFOND is a Juno science Team Member and assists the Principal Investigator in the detailed planning of the auroral observations. In addition, B. Bonfond is directly involved in the processing and interpretation of the data of the supporting HST campaign.
Prof Jean-Claude GERARD is co-Investigator of UVS and of the Juno InfraRed Auroral Mapper (JIRAM). In that regard, J.-C. Gérard leads the comparison of ultraviolet and infrared imaging and spectroscopy from the UVS and JIRAM instruments.


The slit of the UVS spectrograph is able to scan the auroral region by taking advantage of Jupiter's rotation, Juno's spin and orbital motion, as well as of the steerable pickup mirror of UVS, built and tested at CSL. This simulation (credit: B. Bonfond, ULg) shows how the field of view (green lines) is very rapidly changing with time. In this simulation, the northern aurora is continuously observed for almost three hours prior to perijove.
Reconstruction of an image of Jupiter's aurora obtained by scanning the UVS slit across the pole (credit: D. Grodent, ULg). This simulation uses a long sequence of HST images (movie) previously obtained with the STIS camera. The simulation is combining the data obtained from 5 consecutive rotations of Juno (5 times 30 sec).
