Juno is going to scan the surface of and the regions beneath it, while orbiting the planet as shown in my animation: Juno is going to be in polar orbits; since the planet revolves around its own axis with a day, lasting a bit more than 9 earth-hours, Juno can scan a significant area of the giant planet, which is almost 10 times bigger than the Earth; during this time, Juno is also turning around while directing its instruments through many different angles in supporting the laborious and risky process.
Alaska - not industry-guru Florida - is particularly prime to provide polar launch service, as launches into low polar orbit are more efficient at high latitudes.
The facility, located on Kodiak Island's Narrow Cape, 40 miles southeast of Kodiak City, will launch small- to medium-sized rockets carrying satellite payloads of up to 8,000 pounds into polar orbit.
