SpaceX plans to launch 10 Iridium communications satellites on a used Falcon 9 rocket from Vandenberg Air Force Base in California on Friday.
Liftoff is set for 10:13 a.m. EDT, just after sunrise on the West Coast.
Live coverage will begin 15 minutes before liftoff.
The mission will be the 5th of 8 SpaceX flights for Iridium Communications. They're planning on sending a total of 75 satellites into space by mid-2018.
