When I was looking into Forward Error Correction a while back all of the impressive stuff was for downlinks from remote space probes. I don't know any specifics around the Juno probe however most of the techniques usually sent 2-3x the amount of data actually downloaded because a missed frame was 1.5hrs(43mins @ Speed of light from Earth->Jupiter). Being able to reconstruct a frame with redundant data was critical. Combined with a low power transmitter 6mb is pretty reasonable.
