NASA Launch Manager Dr. Denton Gibson has given NASA’s Nancy Grace Roman Space Telescope mission a “go” to proceed toward launch.

SpaceX confirms Falcon Heavy has begun engine chill, flowing a small amount of supercold propellant through its engines to condition them for ignition.

SpaceX confirms that liquid oxygen, or LOX, loading is now underway for Falcon Heavy’s second stage. All the major propulsion elements of the rocket carrying NASA’s Nancy Grace Roman Space Telescope spacecraft are now in propellant-loading operations at NASA’s Kennedy Space Center in Florida.

SpaceX has confirmed that second stage fueling is now underway for the Falcon Heavy rocket, carrying NASA’s Nancy Grace Roman Space Telescope spacecraft from NASA’s Kennedy Space Center in Florida.

After receiving a “go” from the NASA team, the SpaceX launch director verified Falcon Heavy is ready to begin propellant-loading operations at Launch Complex 39A at NASA's Kennedy Space Center in Florida.

NASA’s live broadcast begins for the launch of the agency’s Grace Roman Space Telescope. Liftoff aboard a SpaceX Falcon Heavy rocket is targeted for 7:26 a.m. EDT from Launch Complex 39A at NASA's Kennedy Space Center in Florida.

There are several key milestones during launch coverage of NASA’s Nancy Grace Roman Space Telescope.
