TARGETS
Jupiter, Io, Europa
Juno is a orbiter mission by NASA / JPL targeting Jupiter. Launched August 5, 2011. Currently 5.2722 AU from the Sun.
ABOUT JUNO
Juno is a NASA spacecraft orbiting Jupiter in a highly elliptical polar orbit. It studies Jupiter’s composition, gravity field, magnetic field, and polar magnetosphere. Juno is the farthest solar-powered spacecraft from the Sun. Its extended mission includes close flybys of Jupiter’s moons Io, Europa, and Ganymede.
KEY DISCOVERIES
- Jupiters core is diffuse, not solid
- Complex cyclone patterns at Jupiters poles
- Jupiters magnetic field is 10x stronger than expected in places
- Extensive volcanic activity on Io from close flybys
TECHNOLOGY & FIRSTS
- Farthest solar-powered spacecraft (5.2 AU)
- First spacecraft in polar orbit around Jupiter
- Uses 3 large solar arrays totaling 60 mu00b2
