Live coverage: SpaceX to launch a Falcon 9 booster into retirement on Intelsat mission

SpaceX will launch one of its reusable Falcon 9 rocket boosters for the last time Saturday on a rare expendable mission for Intelsat, devoting all of the launcher’s propellant toward placing a pair of television broadcasting satellites into orbit. Intelsat says it paid SpaceX an additional fee for the expendable mission. The two-hour launch window opens at 11:06 a.m. EST (1606 GMT).
