On July 4th, in just a few days, the Juno spacecraft is schedule to make its insertion into a highly elliptical orbit around Jupiter. Juno has been on its way to Jupiter for 5 years. Though scientist will be watching it closely because of the time lag Juno will have to park itself in orbit on its own.
Juno missions differs from previous in that the elliptical orbit will bring it closer to Jupiter than any previous mission to make measurements. This is dangerous because Jupiter has a very high background radiation, powerful magnetic field and other dangers. If the mission is successful and I pray it will be, we will learn many new things about our gas giant neighbor.
