SpaceX is set to launch two missions today, starting with a European TV satellite called Astra 1P from Florida's Cape Canaveral Space Force Station.
The launch window opens at 5:35 p.m. EDT (2135 GMT), followed by a second launch of 20 Starlink broadband satellites from California's Vandenberg Space Force Base at 11:00 p.m. EDT.
The Falcon 9 rocket's first stage will attempt a landing on the droneship 'Just Read the Instructions' in the Atlantic Ocean after launching Astra 1P.
Astra 1P, once in orbit, will provide TV broadcasting service to customers across Europe.
