Jupiter: Into the Unknown
(NASA Juno Mission Trailer)

Secrets lie deep within Jupiter, shrouded in the solar system's strongest magnetic field and most lethal radiation belts. On July 4, 2016, NASA's Juno spacecraft will plunge into uncharted territory, entering orbit around the gas giant and passing closer than any spacecraft before. Juno will see Jupiter for what it really is, but first it must pass the trial of orbit insertion. For more information: http://www.nasa.gov/juno and http://missionjuno.swri.edu

1. Jupiter orbital insertion!

You could have defined the abbreviation in your post, or just used the definition as the title. It took me a few seconds to figure it out. It was only that I was up on the Juno mission that I was able to do that. I suspect that many won't know what your thread is about.

Nothing left there but dark matter around a black hole........

In all seriousness, it was the Galileo probe.
