Juno Spacecraft at Planet Jupiter Notebook

The NASA Juno space probe was launched in 2011 on a mission to study the planet Jupiter. It entered a polar orbit of Jupiter in 2016 to measure gravity, magnetic fields and thermal radiation. Juno is powered by three large solar panels the provide electricity to the spacecraft. Its mission has been extended until July 30, 2021, at which time Juno will be deorbited into the atmosphere of Jupiter so that it doesn’t accidentally contaminate any of the Jovian moons. Juno is shown soaring over the south pole of Jupiter.
