TAMPA, Fla. (WFLA) — SpaceX launched its Falcon 9 rocket Thursday morning from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida.

The private space company sent an additional 54 Starlink satellites into low-Earth orbit.

An instantaneous launch window opened at 10:50 a.m. ET.

SpaceX said the Falcon 9’s first stage booster supporting Thursday’s mission was previously used to launch the GPS III Space Vehicle 04, GPS III Space Vehicle 05, Inspiration4, Ax-1, Nilesat 301, and four other Starlink missions.

After stage separation, the first stage returned to Earth and landed on the “A Shortfall of Gravitas” droneship, which was stationed in the Atlantic Ocean.
