The Juno mission's science objectives will be achieved with a payload of seven instruments onboard the spacecraft, designed to collect key new data. A camera for Education and Public Outreach called JunoCam will also provide a visual context for the Jupiter observations, especially of the North Polar region. The science investigations and supporting instruments are:

Juno Payload System
  1. Atmospheric Structure
  2. Magnetic Field Investigation
    • Flux Gate Magnetometer and Scalar Helium Magnetometer
    • Advanced Stellar Compass (ASC)
  3. Juno Spacecraft

  4. Polar Magnetosphere Suite
    • Jovian Auroral Distribution Experiment (JADE)
      and Energetic Particle Detector Instrument(JEDI)
    • Radio and Plasma Wave Sensor(WAVES)
    • Aurora from Ultraviolet Imaging Spectrograph (UVS)
    • Jovian Infrared Auroral Mapper (JIRAM)
  5. Interior Structure
    • Gravity Science Experiment
  6. Jupiter Polar Context Imaging and E/PO -- JunoCAM
