"This is the first time that a rocket has taken off from one country, gone to space and landed in another country!" -- SpaceX founder and CEO Elon Musk.

SpaceX on Friday morning launched 23 Starlink satellites from Space Launch Complex at Cape Canaveral Space Force Station in Florida, the 450th flight involving a Falcon 9 rocket.

As of Thursday evening, SpaceX has confirmed the Starlink 12-8 launch is targeted for 1:14 a.m. Saturday from Cape Canaveral Launch Complex 40. While SpaceX usually targets the beginning of the allotted window, various factors, such as weather at the launch and booster landing sites, play a role in timing.
