Update April 27, 10:48 a.m. EDT (1448 UTC): SpaceX scrubbed the mission due to poor weather.
SpaceX stood down from launching its first Falcon Heavy rocket in more than a year and a half due to poor weather on Monday, April 27.
A new launch date hasn't been announced yet, possibly as the Eastern Range is considering the timing of unloading the core stage of NASA's Space Launch System rocket from the agency's Pegasus barge.
