Juno is a NASA space probe orbiting the planet Jupiter. Built by Lockheed Martin and operated by NASA's Jet Propulsion Laboratory, the spacecraft was launched from Cape Canaveral Air Force Station on August 5, 2011, 16:25:00 UTC, as part of the New Frontiers program. Juno entered a polar orbit of Jupiter on July 5, 2016, 03:53:00 UTC, to begin a scientific investigation of the planet. After completing its mission, Juno was originally planned to be intentionally deorbited into Jupiter's atmosphere, but has since been approved to continue orbiting until contact is lost with the spacecraft. It will continue to explore Jupiter to study Jovian rings and the inner moons area, which is not well explored; this phase will also include close flybys of the moons Thebe, Amalthea, Adrastea, and Metis.
