Members of the news media begin setting up at the NASA News Center to await liftoff of the SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy Space Center in Florida. The iconic Vehicle Assembly Building and Launch Control Center are visible in the background. The Falcon Heavy demonstration flight will be a significant milestone for the world's premier multi-user spaceport. In 2014, NASA signed a property agreement with SpaceX for the use and operation of the center's pad 39A, where the company has launched Falcon 9 rockets and is preparing for the first Falcon Heavy. NASA also has Space Act Agreements in place with partners, such as SpaceX, to provide services needed to process and launch rockets and spacecraft.
