Sentient Marmite: The Truth may make you fret.
As I write, the orbital insertion is 7 days off
Countdown to Jupiter: Juno just seven days from orbit
I look forward to hear more about this mission over the next 7 months approx.

Much of its roughly 3,640 kg (8,000 pound) weight is shielding to protect the probe from the radiation of the planet's much-more-intense version of Earth's Van Allen belts.
total original weight was 3625kg, that includes the craft, fuel and oxidizer. The craft itself is 1593kg, so the electronics vault shielding, which is 200kg comes in at 12.5% of the crafts weight. This excludes the shielding for cabling and instruments outside the vault.
