At closest approach, Juno flies within 2,600 miles of Jupiter's cloud tops, making it one of the fastest spacecraft ever built at speeds exceeding 130,000 miles per hour.
- 03
Juno's radiation vault, a 400-pound titanium chamber, protects sensitive electronics from Jupiter's intense radiation belts that produce doses equivalent to 100 million dental X-rays annually.
- 02
Juno's primary science mission lasted five years, with the spacecraft completing 37 orbits of Jupiter between 2016 and 2021 while studying the planet's magnetic field and atmosphere.
