Juno is a NASA space probe orbiting the planet Jupiter. It was built by Lockheed Martin and is operated by NASA's Jet Propulsion Laboratory. The spacecraft was launched from Cape Canaveral Air Force Station as part of the New Frontiers program. Juno's mission is to measure Jupiter's composition, gravitational field, magnetic field, and polar magnetosphere.
Atlas V is an expendable launch system in the Atlas rocket family. It was formerly operated by Lockheed Martin and is now operated by United Launch Alliance (ULA), a joint venture with Boeing. Each Atlas V rocket uses a Russian-built RD-180 engine burning kerosene and liquid oxygen to power its first stage and an American-built RL10 engine burning liquid hydrogen and liquid oxygen to power its Centaur upper stage. The RD-180 engines are provided by RD Amross, while Aerojet Rocketdyne provides both the RL10 engines and the strap-on boosters used in some configurations. The standard payload fairing sizes are 4 or 5 meters in diameter and of various lengths. Fairings sizes as large as 7.2 m in diameter and up to 32.3 m in length have been considered. The rocket is assembled in Decatur, Alabama and Harlingen, Texas.
United Launch Alliance (ULA) is a joint venture of Lockheed Martin Space Systems and Boeing Defense, Space & Security. ULA was formed in December 2006 by combining the teams at these companies which provide spacecraft launch services to the government of the United States. ULA launches from both coasts of the US. They launch their Atlas V vehicle from LC-41 in Cape Canaveral and LC-3E at Vandeberg. Their Delta IV launches from LC-37 at Cape Canaveral and LC-6 at Vandenberg.

Using NASA’s Juno spacecraft, scientists have calculated the rate of oxygen production on Jupiter’s moon Europa — the first time any spacecraft had directly measured charged oxygen and hydrogen particles from the moon’s atmosphere. From th…
"The cumulative effect of all that radiation has begun to show."
Continuing to gather bonus science data in an extended mission around Jupiter, NASA’s Juno spacecraft recorded sharp views of the icy moon Europa Sept. 29 as the solar-powered probe raced by at a relative velocity of nearly 53,000 mph.
"We are screaming by pretty fast."
In a series of newly released papers from a science team on NASA’s Juno mission, new data is helping researchers discover how Jupiter’s atmosphere functions underneath the planet’s thick upper cloud layer.
