Its targets embody Callisto, Europa and Ganymede, the most important moon within the photo voltaic system.
The house company mentioned all the pieces else goes properly with the spacecraft, in regards to the measurement of a small bus. A radio antenna, photo voltaic panels and a 35-foot (10.6-meter) growth for measuring Jupiter’s magnetic discipline have all been efficiently deployed.
