Detectors' characterization of MAJIS instrument onboard JUICE

The detectors of MAJIS were characterized at the B.RCLab in the BIRA-IASB facilities. This is now one of our important assets, available for external use too.

Expected performances of the MAJIS instrument onboard JUICE

Using ASIMUT-ALVL, we are able to simulate the expected measurements as performed by MAJIS. This is very useful in order to prepare for the JUICE mission. Our scientists are also in charge of preparing the planning of operations for the Jupiter atmospheric investigations under the responsibility of ESA and the Instrument Lead Scientist, F. Poulet (IAS, France).

Spectroscopic measurements

In the frame of various projects, among which RT-MOLEXO, we develop experimental set-ups or we collaborate to improve the spectroscopic databases in preparation for the JUICE mission.

MAJIS: on a quest to Jupiter and its icy moons

MAJIS is the visible and infrared imaging spectrometer which is on board the L1 ESA/JUICE mission towards Jupiter and its icy moons. It is a hyper-spectral imaging spectrometer for observing tropospheric cloud features and minor species on Jupiter and for the characterisation of ices and minerals on the surfaces of icy moons.
MAJIS will cover the visible and infrared wavelengths from 0.4 to 5.7 microns, with spectral resolution of 3-7 nm. The spatial resolution will be up to 25 m on Ganymede and about 100 km on Jupiter.
