AB: JIRAM, the Jovian InfraRed Auroral Mapper, is part of the payload of the NASA New Frontiers mission Juno to Jupiter to be launched in August 2011. JIRAM scientific goals are: the exploration of the dynamics and the chemistry of Jovian auroral regions by high contrast imaging and spectroscopy, the study of the hot spots through the Jupiter troposphere in order to determine their vertical structure and hence test their formation mechanisms and, eventually, the sounding of the Jupiter atmosphere to map water moist convection and determine the water abundance and other constituents at depths corresponding to the water clouds. The JIRAM heritage comes from Italian Visual-InfraRed Imaging Spectrometers dedicated to planetary exploration like Cassini /VIMS-V, Rosetta and Venus Express /VIRTIS, and Dawn /VIR-MS. However, Juno presents more technological challenges due to the harsh radiative environment generated by the Jupiter powerful magnetic field, the spinning spacecraft, its speed in respect to the target to be observed ( which is more than 50 km/s at the Jupiter closest approach) and the shortness of the mission which impose a very tight observation schedule. JIRAM shares a single telescope, between an infrared camera and a spectrometer to allow a large observational flexibility in obtaining at the same time simultaneous images in a field of view of 5.9x1.7 deg and in the L ( 3.4 m) and M ( 5 m) bands. JIRAM will also perform measurements of spectral radiance over the central zone of the M image. It will also be able to compose spectral images of the planet between 1.85 and 5.2 m with a spectral resolution better than 10 nm.
