Juno (spacecraft)
NASA spacecraft orbiting the planet Jupiter
Juno is an unmanned NASA New Frontiers spacecraft. It studies the planet Jupiter from orbit. It is the first mission to an outer planet to use solar panels for power instead of a radioisotope thermoelectric generator. The spacecraft was launched on August 5, 2011 from the Cape Canaveral Air Force Station and entered a polar orbit of Jupiter on July 5, 2016. Scott Bolton is leading the mission.[6]
