The launch of a Falcon 9 rocket will wait until at least Sunday night after missing several planned attempts earlier in the day at Vandenberg Space Force Base.
The two-stage rocket built by SpaceX will target a 10:33 p.m. Sunday departure from Space Launch Complex-4 on South Base.
However, the team has additional opportunities until 2:33 a.m. Monday, if needed.
After trying for liftoff Saturday night and then delaying it several times into Sunday morning with attempts aiming for 12:51 a.m., 1:51 a.m. and 2:54 a.m., SpaceX crews cancelled the countdown.
The rocket remains ready to carry 22 Starlink satellites into orbit as the SpaceX-designed and -built constellation continues to expand the number of craft creating a system to provide internet access in remote and rural areas across the planet.
After finishing its part of the flight, the first-stage booster will return to touch down on the Of Course I Still Love You droneship in the Pacific Ocean.
The first-stage booster, one of the costliest components on a rocket, has already flown 14 other missions for an assortment of government and commercial customers.
Since the start, SpaceX has touted reuse of first-stage boosters as a way to cut costs and time between launches. The firm also captures the two halves of payload fairings, or nose cones, so they can be used again.
A live webcast of the Vandenberg mission will begin on the SpaceX account of the site formerly known as Twitter about five minutes before liftoff.
