The next SpaceX Falcon 9 rocket will launch a Starlink batch from pad 39A on November 30 at 3:11-7:11 p.m. EST.

It's also on the FAA advisory now.

SpaceX’s Falcon 9 is targeting the launch of 29 Starlink satellites to low-Earth orbit from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center in Florida.

A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the X TV app.

This will be the fourth flight for the first stage booster supporting this mission, which previously launched three Starlink missions. Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.
