Abstract
  • The InfraRed Auroral Mapper (JIRAM) is simultaneously an imager and a spectrometer on board of the Juno mission. Jupiter's reflected and emitted light in the range 2-5 ?m can be sensed through its spectral channel and H3+ emissions analyzed to retrieve auroral parameters. JIRAM is also able to map the infrared Jupiter aurora in the 3.5 ?m and planet's thermal emissions in the 5 ?m wavelength ranges through its L-band and M-band imager filters . The main scientific goals are the study of auroras, hot spots and other Jupiter atmospheric structures detectable in its working spectral range. Concurrently with the Juno Earth fly-by, that will occur on October 9th of this current year, JIRAM will observe the Moon during its transit approaching the Earth. As the instrument's temperature cannot be actively controlled, operating with a passive cooling system, the Earth will not be observed during the closest approach. A dramatic temperature increase of the instrument, far above its performance limit, is expected in fact by the illumination of the instrument's cooling radiators due to our planet reflection of the solar illumination. The Moon will be the only chance for an extended target observation that JIRAM can experience before Jupiter. Consequently, this opportunity is of pivotal importance being the only chance for a real in-flight test to verify the instrument performances and the radiometric calibration in real observational set up. The instrument will be operated in the same functional configuration that it will use at Jupiter. So far, the only absolute radiometric calibration has been performed in lab during the on ground calibration and functional test sessions. The internal calibration unit is mainly devoted to the spectral calibration checking while the absolute radiometric calibration has to verified and confirmed in flight. Results of lunar observations will be presented. (literal)
