ORIGINAL STORY: SpaceX is scheduled to launch a Falcon 9 rocket from Vandenberg Space Force Base Tuesday at 8:15 a.m.
It's the fourth launch attempt for this mission, which was first set to liftoff Sunday morning, but was moved in order to complete pre-launch checkouts.
The rocket will deliver 49 Starlink satellites into low-Earth orbit, along with D-Orbit’s ION Satellite Carrier "SCV009 Eclectic Elena."
About eight minutes after liftoff, SpaceX will aim to land the rocket's first stage booster on the Of Course I Still Love You droneship stationed in the Pacific Ocean.
The booster being used in this mission has been used in six other missions.
A live webcast of the launch is scheduled to begin about five minutes before liftoff.
