PACE postponed: NASA, SpaceX stand down launch attempt because of high booster-landing winds

Update 10:14 p.m. Tuesday: SpaceX announced crews will now target 1:33 a.m. EST Wednesday for launch of NASA's PACE spacecraft, citing expected high winds at the first-stage booster landing zone.

Original story: NASA’s first Earth-science launch of 2024 is scheduled to launch overnight — but poor weather may very well postpone the mission, the Space Force's 45th Weather Squadron warns.

SpaceX and NASA are targeting 1:33 a.m. EST Tuesday to launch the PACE spacecraft aboard a Falcon 9 rocket from Launch Complex 40 at Cape Canaveral Space Force Station.

If the Falcon 9 lifts off, SpaceX reported the first-stage booster will target landing 7 minutes, 32 seconds later back at the Space Force base — triggering late-night sonic booms across the vicinity.

However, an early 45th Weather Squadron forecast only projected 40% odds of "go for launch" conditions at the Cape, citing cumulous clouds, liftoff winds and thick cloud layers.
