In ancient Roman mythology, Juno was the chief goddess, sister, and wife to Jupiter, king of the gods. Despite her husband’s tumultuous personality, Juno was loyal, and persistent in keeping tabs on Jupiter’s secret affairs.
On August 5, 2011, Juno—the JUpiter Near-polar Orbital—launched from Cape Canaveral and began its long journey to rendezvous with Jupiter. In 2013, Juno briefly returned to Earth’s orbit to propel itself on course by performing a gravitational slingshot maneuver on trajectory toward the gas giant.
