Welcome to Florida Today's Space Team live coverage of tonight's SpaceX Falcon Heavy rocket launch — followed less than three hours later by SpaceX Falcon 9.
SpaceX is targeting a 8:07 pm EST launch of a Falcon Heavy rocket from Pad 39A at Kennedy Space Center on the USSF-52 national security mission, lifting the Space Force's X-37B robotic space plane into orbit for its seventh secret mission.
Falcon Heavy's twin-sided boosters will generate sonic booms aimed at landing at SpaceX's Landing Zones 1 and 2 at the Cape Canaveral Space Force Station.
Then at 11:01 p.m., SpaceX will launch a Falcon 9 rocket carrying 23 Starlink Internet satellites into low Earth orbit. That second launch will take place from Launch Complex 40 at the Cape Canaveral Space Force Station.
No local noise boom was expected during that mission. Instead, the Falcon 9's first-stage booster will aim to land on a drone ship at sea.
When SpaceX's live webcast hosted on X (formerly Twitter) becomes available 15 minutes before Falcon Heavy launch, it will be posted at the top of this page.
Falcon Heavy refueling is currently underway
Updated 7:28 pm: The SpaceX crew is now fueling the Falcon Heavy first stage with rocket-grade kerosene and liquid oxygen in Pad 39A, visual notes indicate.
SpaceX: 'All systems are good'
Updated 7:13 pm: SpaceX just announced: “All systems are good and weather is 90% favorable for Falcon Heavy USSF-52 launch tonight.”
That represents an improvement over the 80% “go to launch” odds cited in the Space Force's 45th Weather Force forecast released Wednesday.

Tickets to see the Falcon Heavy Launch are sold out
UPDATE 6:16 PM: All viewing tickets for the upcoming Falcon Heavy launch at the Kennedy Space Center Visitor Complex sold out earlier today, spokeswoman Rebecca Burkman said.
Viewing tickets for seats in the campus' Apollo/Saturn V Center, accessible by bus and located about 3 miles from Pad 39B, sold out this morning. Online ticket sales for viewing at the main visitor complex ended this afternoon.
“We always expect more traffic this holiday week. Of course, having a release adds to that interest from a consumer standpoint,” Burkman said.
“There's definitely a lot of interest in seeing a launch. It's kind of a bucket-list experience for a lot of people who were going to Orlando or other parts of Central Florida,” he said.
“We've seen people who have driven two hours – two to three hours. We're here to see it. So, we'll have a lovely lunch tonight and entertain everyone,” he said.
