FALCON HEAVY — DOUBLE SONIC BOOM EXPECTED
Sunday, Aug. 30 | Window: 7:10–7:30 AM EDT | Scheduled liftoff 7:26 AM
Backup: Monday, Aug. 31, 7:22 AM EDT
Falcon Heavy's two side boosters fly back and land about 9 miles south of the pad at Cape Canaveral Space Force Station. Because they touch down within seconds of each other.
The payload: NASA's Nancy Grace Roman Space Telescope, headed to an orbit near the Sun-Earth L2 point, about 930,000 miles out. Roman studies dark energy, dark matter, and exoplanets with a field of view far wider than Hubble's, per NASA.
Weather officers put the odds at 60% favorable as of Friday's readiness review — timing could still shift. (Source: NASA)
