Falcon Heavy Launch Delayed Due to Engine Swap and Weather Conditions.

SpaceX's Falcon Heavy rocket was rolled back to its launch pad in Florida for a scheduled launch with ViaSat 3 Americas, a Boeing-built internet satellite, and two small rideshare payloads. The rocket was delayed for eight days for an engine swap after a test-firing of its 27 main engines on April 13. The mission will be the sixth launch of a SpaceX Falcon Heavy rocket since 2018, and the second of as many as five Falcon Heavy flights the company plans this year.
