Thats because the missions destination is a so-called polar orbit - a path that passes through the earths poles mainly from north to south. In fact, it will be the first time since 1969 that a rocket will take off from Florida and fly south.
So far, most of the U.S. polar launches have taken place off the southern coast of California. As a result, the rocket went south over open oceans, not over densely populated land.
SpaceXs Falcon 9 rocket blasted off from SpaceXs launch site at Cape Canaveral Air Force Base at 7:18 p.m. Eastern time. The rocket then flew south, skimming the southeast coast of Florida near Miami, and then over Cuba.
The main satellite for the launch is saocom1b, and there are two small satellites to take a ride. Saocom1b is the second of two identical Earth Observation Satellites signed by SpaceX for the Argentine space agency. Together, the two satellites will use radar to observe the earth to hunt for disasters that may damage agriculture, mining, fishing and other industries. The satellite will enter a polar orbit called the sun synchronous orbit. This path allows satellites to pass through the same area of the earth at the same time every day, which is very good for earth observation satellites that want to track the position of the earth over time.
