• • Jovian Infrared Auroral Mapper (JIRAM)

    The Jovian Infrared Auroral Mapper (JIRAM) will study Jupiter’s atmosphere in and around the auroras, learning more about the interactions of the auroras, the magnetic field, and the magnetosphere. JIRAM will be able to probe the atmosphere down to 50 to 70 kilometers (30 to 45 miles) below the cloud tops, where the pressure is five to seven times greater than at Earth’s sea level.
