On the evening of July 4, 2016, NASA’s New Frontiers spacecraft Juno will ignite its main engine to enter an unprecedented cloud-skimming orbit around Jupiter, our solar system’s largest planet. Jupiter is the archetype giant planet, now known to be a very common type of substellar object in our Galaxy. Juno will make a series of close-range passes to look at Jupiter’s atmosphere and interior and obtain benchmark data about the class of planet that best preserves the first million years of planetary system origins.
