SpaceX launch recap: Starlink mission Saturday night from NASA's Kennedy Space Center
Launch recap: Scroll down to review live coverage of the Saturday, March 23, liftoff of a SpaceX Falcon 9 rocket from NASA's Kennedy Space Center.
It's launch day — following a Friday night scrub!
Welcome to FLORIDA TODAY's Space Team live coverage of tonight’s hours-delayed SpaceX Starlink mission from NASA's Kennedy Space Center.
SpaceX is now targeting 11:09 p.m. EDT — nearly four hours later than originally announced — for its second attempt at launching a Falcon 9 rocket from pad 39A.

This Starlink 6-42 launch attempt comes on the heels of Friday night's postponement, which was announced hours before liftoff amid a dreary weather forecast. The Falcon 9 will deploy a batch of Starlink internet satellites, which are packed inside the fairing atop the 230-foot rocket.
No local sonic booms are expected. After soaring skyward along a southeasterly trajectory, the rocket's first-stage booster will target landing aboard a drone ship out at sea 8? minutes after liftoff.

SpaceX Falcon 9 fueling has finally begun
Update 10:34 p.m.: Finally: Falcon 9 fueling procedures are underway at pad 39A, SpaceX just announced.
That means tonight’s Starlink mission is committed to lift off at 11:09 p.m. without any countdown delays, or else the launch must be postponed.
Are worst storms finally blowing offshore?
Update 10:15 p.m.: The National Weather Service's Melbourne station radar loop shows that the fierce red storms that passed near the Cape this evening have moved offshore.
SpaceX's much-delayed 11:09 p.m. liftoff target is less than an hour away. Will the rocket launch?

SpaceX booster slated to fly 19th mission
Update 9:29 p.m.: Tonight's mission would mark the 19th flight for this Falcon 9 first-stage booster, SpaceX reported.
The well-traveled booster previously launched GPS III-3, Turksat 5A, Transporter-2, Intelsat G-33/G-34, Transporter-6, Intuitive Machines IM-1 and a dozen Starlink missions, SpaceX reported.
Following stage separation, crews expect the booster to land on the drone ship Just Read the Instructions out on the Atlantic Ocean 8 minutes, 26 seconds after liftoff.
Storms still sweeping north of Cape
Update 8:30 p.m.: National Weather Service radar shows fierce storms continuing to pass north of the Cape — along with potentially poor booster-recovery conditions in the Bahamas.
SpaceX sets lengthy delay: 11:09 p.m.

Update 7:24 p.m.: For weather watchers, the National Weather Service has again extended that special marine warning just north of the Cape. The warning now elapses at 8:15 p.m. — and the impacts are now more severe than earlier.
Impacts may now include wind gusts topping 40 knots, large hail, possible waterspouts and steep waves.

Space Force: 75% 'go for launch'
Update 6:17 p.m.: The Space Force's 45th Weather Squadron pegged the odds of "go for launch" weather at 75%.
The squadron's forecast did note a low-to-moderate risk of upper-level wind shear, along with a moderate risk of unfavorable weather and sea conditions for the first-stage booster landing aboard a SpaceX drone ship out at sea.
"On Saturday, the low pressure will be tracking up the Eastern Seaboard, leaving the Spaceport with northwesterly winds and isolated, wrap-around showers. The primary launch weather concerns will be Liftoff Winds and the Cumulus Cloud Rule associated with the isolated showers," the forecast said.
