This morning, SpaceX will launch a pair of WorldView Legion imaging satellites for Maxar, a space technology company, and give the Space Coast the thrill of a booster landing with accompanying sonic boom.
According to SpaceX, the launch window runs from 9 a.m. until 10 a.m. EDT. The satellites will launch atop a Falcon 9 rocket from Space Launch Complex – 40, which is located just south of Kennedy Space Center. The launch will travel in a northeast trajectory.
The Space Force 45th Weather Squadron predicts a 80% chance of favorable weather during the launch window.

Eight and a half minutes after lift off, the Falcon 9 first stage will land back at Cape Canaveral on Landing Zone 1, causing a sonic boom. The sound is generated when the Falcon 9 falls faster than the speed of sound.
Not to worry, as the landing burn and grid fins slow the booster down and direct it before landing.
This is where it gets interesting −spectators will see the Falcon 9 come down before the sonic boom is heard. This is simply due to physics, as light travels faster than sound.
These will be the third and fourth satellites in the Maxar series, which is set to consist of six satellites in total.
