Juno successfully entered Jupiter's orbit!
Unfortunately you can't track Juno with DESA Satellite Tracker - DESA only tracks satellites orbiting earth. You can however download a great app from NASA (also free) that allows you to track Juno in real time.
NASA's Eyes can be downloaded from: https://eyes.nasa.gov/
This great app from NASA also allows you to do much more like look at EXOPLANETS and track the ISS in real time (like DESA Satellite Tracker - but it also allows you to view the ISS close up in 3D).
