The powerful rocket will carry an assortment of cargo to orbit, including a solar sail, an atomic clock and the ashes of 152 people.
The world’s most powerful operating rocket will take flight
again on Tuesday morning.
SpaceX’s Falcon Heavy rocket is set to blast off from Kennedy Space Center in Florida. This will be the third trip for the Falcon Heavy. Its 2018 test launch lofted founder Elon Musk’s Tesla roadster into the solar system, and a second mission in Aprilcarried a Saudi communications satellite to orbit.
This time it’s carrying 24 satellites for the Defense Department and other customers, and Mr. Musk called it SpaceX’s “most difficult launch ever.” A successful mission could lead to additional business from the United States government for Falcon Heavy.
