The Falcon 9 rocket at Vandenberg Space Force Base will wait until Tuesday morning before trying to get off the ground.
Liftoff will aim for 8:15 a.m. from Space Launch Complex-4 on South Base, according to a Space Exploration Technologies update.
On Monday, SpaceX said it would skip the morning liftoff attempt and try for an early afternoon departure.
A few hours later, SpaceX said the launch attempt would take place on Tuesday morning “to allow additional time for pre-launch checkouts.
“Weather is looking good for liftoff,” the SpaceX announcement said.
The firm first planned for a Sunday liftoff, but postponed the mission, also due to pre-launch chores.
The rocket will deliver some 49 Starlink satellites into orbit as SpaceX continues to expand its constellation of craft to provide internet access to remote areas of the world.
Also hitching a ride for this mission will be D-Orbit’s ION SCV009 Eclectic Elena carrying several other missions.
The first-stage booster will land on a droneship several hundred miles south of the Central Coast so sonic booms are not expected.
A live webcast of the countdown’s final minutes and liftoff will start five minutes before departure at the SpaceX website or YouTube channel.
