Another 40 days or so and the sun would be between the earth and Jupiter, presumably stopping the communications for a while. How long is Juno supposed to stick around Jupiter, is it just going to be left there forever or will it go out further or come back to earth bringing samples or what?
Samples?
Drops of Jupiter?
Juno will be around Jupiter for 37 orbits or about 20 months. After that it will be deorbited and crash into the planet in February of 2018.
