Subsequent to NASA's Galileo mission (1995), Juno is only the second to have accomplished this feat. While in orbit, the Juno mission aims to better understand the gas giant in the following 20 months of its science phase. Juno also happens to be the fastest ever craft built by humans, travelling at speeds of over 260,000 kilometers per hour (74 km/s). To arrive at Jupiter, Juno took an elliptical heliocentric orbit through the Solar System involving an Earth fly-by two years after launch. This fly-by provided Juno with a further boost of around 3.9 km/s, enabling Juno to reach Jupiter in just under 5 years. "Juno, welcome to Jupiter" were the words heard throu...
