SpaceX is pushing back its second Falcon 9 launch this week to 11:43 p.m. The new launch window opens at 11:39 p.m. on Friday, lasting 17 minutes. The liftoff will take place from Space Launch Complex 4E. A sonic boom can be expected when the first stage lands in Landing Zone 4.
A live stream of the launch is scheduled to start about 15 minutes prior to liftoff. This marks SpaceX’s eighth launch at Vandenberg Space Force base this year. Firefly Aerospace had planned to launch its Message in a Booster mission on Saturday, but that has now been delayed.
