A Falcon 9 rocket launch planned for this weekend at Vandenberg Space Force Base would mark the third of the month from the West Coast.
Following Oct. 9 and Oct. 21 blastoffs, another SpaceX rocket will lift off from Space Launch Complex-4 on South Base.
On Saturday, SpaceX said the team was targeting a 2 a.m. Sunday departure for the 22 satellites, with two other opportunities at 2:50 a.m. until 3:08 a.m.
If delayed longer, six backup opportunities are also currently available starting at 11:06 p.m. Sunday and ending at 2:45 a.m. Monday.
Notices issued ahead of the launch initially said the mission would occur between Friday night and Saturday morning but were revised.
Rocket launches can be delayed for a number of reason including technical troubles, unfavorable weather or the team falling behind in pre-liftoff chores.
While the rocket’s liftoff will make its typical rumble, residents won’t hear the sonic booms that accompany the Falcon’s first-stage booster since it won’t return to Vandenberg.
Instead, the first-stage booster will touch down on the Of Course I Still Love You droneship stationed in the Pacific Ocean.
SpaceX also plans to capture the two halves of the rocket’s nose cone for future reuse.
The West Coast liftoff is one of two planned within 24 hours, with the second taking place from Florida.
Both missions will carry Starlink satellites adding to thousands of others already in orbit in the effort to continue expanding a space-based constellation to provide internet services across the globe in areas where land-based access is not reliable or readily available
Live webcasts of each mission are scheduled to begin on the SpaceX account of the site formerly known as Twitter about five minutes before liftoff.
