The Juno mission launched August 5, 2011 and will orbit the planet for 20 months to collect data on the planetary core, map the magnetic field, and measure the amount of water and ammonia in the atmosphere.

Five years after its launch from Earth, Juno is scheduled to go into orbit around the gas giant on Monday, July 4, 2016.7 of 10Jim Green, director, Planetary Science Division, NASA, left, talks during a media briefing joined by Scott Bolton, Juno principal investigator, second from left, Rick Nybakken, Juno project manager, second from right, and Heidi Becker, Juno radiation monitoring investigation Lead, at Jet Propulsion Laboratory (JPL) in Pasadena, Calif., on Monday, July 4, 2016. The solar-powered spacecraft is spinning toward Jupiter for the closest encounter with the biggest planet in our solar system. NASA's Juno spacecraft will fire its main rocket engine late Monday to slow itself down from a speed of 150,000 mph (250,000 kph) and slip into orbit around Jupiter8 of 10Jim Green, left, celebrates with Scott Bolton in Mission Control at NASA's Jet Propulsion Laboratory as the solar-powered Juno spacecraft goes into orbit around Jupiter on Monday, July 4, 2016, in Pasadena, Calif.9 of 10Scott Bolton, left, and Rick Nybakken are seen in a post-orbit insertion briefing at NASA's Jet Propulsion Laboratory following the solar-powered Juno spacecraft entered orbit around Jupiter on Monday, July 4, 2016, in Pasadena, Calif10 of 10
