Welcome to FLORIDA TODAY's Space Team live coverage of the history-making post-midnight Vulcan rocket launch from Cape Canaveral Space Force Station.

United Launch Alliance will send its next-generation Vulcan rocket on its Cert-1 maiden flight at 2:18 a.m. EST.

"Fueling operations are proceeding as planned at Space Launch Complex-41 to prepare Vulcan for its trek into interplanetary space," ULA officials announced at 10:18 p.m.

The Space Force's 45th Weather Squadron forecasts 85% favorable conditions for the Vulcan launch.

Kicking off a back-to-back launch doubleheader, SpaceX sent a Falcon 9 rocket into low-Earth orbit at 5:35 p.m. Sunday from nearby Launch Complex 40. The Falcon 9 deployed another batch of 23 Starlink internet satellites, which were packed inside the fairing halves atop the 230-foot rocket. Scroll down for updates from that Starlink 6-35 mission.

Check back for Vulcan updates on this page throughout the evening, increasing in frequency about 90 minutes before launch.

Countdown Timer

Liftoff!

Update 2:18 a.m.: ULA has just launched its first Vulcan rocket from Launch Complex 41 at Cape Canaveral Space Force Station.

Final seven-minute countdown begins

Update 2:11 a.m.: The last seven minutes of tonight's Vulcan launch countdown have started, after a status-check poll of two dozen console operators and mission managers.

All good 14 minutes before Vulcan launch

Update 2:05 a.m.: The latest update from ULA:

"We are 14 minutes away from liftoff time of the Vulcan rocket.

"This is United Launch Alliance's 159th launch and the 21st in service to a commercial client. Today begins a new era for ULA as perform the inaugural flight of the versatile Vulcan," the update said.

Weather briefing: 'go for launch'

Update 1:54 a.m.: The Vulcan countdown's final planned briefing by weather officer Brian Belson has concluded with 'go for launch' conditions at Cape Canaveral.

"A series of weather balloons has been launched throughout the countdown from the Range weather station at the Cape to collect measurements of wind speeds and directions to determine if conditions aloft violate the controllability or structural loads on the rocket during ascent. The balloon data was transmitted to ULA engineers in Denver to select a steering profile that minimizes launch vehicle responses," according to a ULA launch update.

Closer view of the Vulcan

Update 1:41 a.m.: Here's a ULA graphic that depicts the various components of the Vulcan rocket.

Vulcan countdown enters hourlong hold

Update 1:27 a.m.: A ULA countdown update posted at 1:18 a.m.: "We are exactly one hour away from liftoff of the inaugural Vulcan rocket for the Certification-1 mission. All activities are on track for a liftoff at 2:18:38 a.m. EST (0718:38 UTC)."

Another update: "The countdown has entered the planned 60-minute built-in hold designed to give a bit of margin to ensure we are ready for Terminal Count and today's launch window. During this pause, the final readiness polls of the launch team and management members will be performed."

Just more than 1 hour till Vulcan launch

Update 1:11 a.m.: ULA officials have tweeted out a nighttime photo of the Vulcan at the launch pad during the fueling process.

Vulcan launching Iris rover to the moon

Update 12:50 a.m.: Pittsburgh-based Astrobotic's robotic lunar lander, Peregrine, will land on the moon Feb. 23 and deploy Iris, a shoebox-sized mini-rover built by Carnegie Mellon University students.

"Over the course of 20 to 60 hours, Carnegie Mellon students of all backgrounds will work together to make live mission-critical decisions. The 2-kilogram rover will execute a series of linear and point turn movements, record images and data, and collaborate with other payloads to understand mobility, navigation and geoscience on the moon," an Iris promotional video said.

Vulcan: 'Green and GO across the board'

Update 12:26 a.m.: In a ULA launch update posted a few minutes ago, "a check of the local weather conditions shows green and GO across the board."

Where can you see the Vulcan launch?

Update 12:00 a.m.: On Friday, ULA officials tweeted this map that shows where spectators in Florida, Georgia and The Bahamas should be able to spot the Vulcan as it ascends into orbit.

Cape Canaveral seeing fair skies, gentle breeze

Update 11:24 p.m.: The National Weather Service reported fair skies, a temperature of 53 and north breeze of 5 mph as of 10:55 p.m. at Cape Canaveral Space Force Station.

The Space Force's 45th Weather Squadron forecast, which called for 85% odds of favorable Vulcan launch weather, listed thick cloud layers as the Cert-1 mission's primary meteorological risk.

"By the primary launch window, high pressure should bring generally favorable weather conditions although there is a slight chance of a Thick Cloud Layers Rule violation from clouds associated with the subtropical jet," the forecast said.

Launch Complex 41 history

Update 10:50 p.m.: As rocket fueling continues, ULA officials shared a variety of historical facts a few minutes ago detailing Launch Complex 41 at Cape Canaveral Space Force Station. Vulcan will mark the 110th flight from the facility:

"The pad was constructed by the U.S. Air Force in the 1960s for the Titan rocket program. There were 27 launches of the Titan family between 1965 and 1999, including NASA's two Viking missions in 1975 that landed on Mars and both Voyager probes to the outer solar system in 1977.

"The site was rejuvenated in support of the Atlas V starting in 1999. It employs a 'clean pad' concept of operations to ready launch vehicles and payloads for ascent into space. Construction to support Vulcan has occurred to transfer the site into a dual-use pad capable of supporting both rocket manifests simultaneously.

"The rocket elements are assembled atop a Vulcan Launch Platform inside the Vertical Integration Facility located adjacent to the launch pad. The platform and fully stacked Vulcan then travels by rail approximately 1,800 feet northward from the VIF to the pad for the final countdown, fueling and liftoff."

Coast Guard supporting Vulcan launch

Update 10:15 p.m.: The Port Canaveral-based U.S. Coast Guard cutter Skipjack, a 110-foot vessel designed for law enforcement operations, is staging to secure the Vulcan's offshore navigational warning zones.

The Space Launch Delta 45 rocket launch advisory shows the Vulcan will track essentially due east from the Cape, in contrast to the southeasterly trajectory traveled by today's SpaceX Falcon 9 on the Starlink 6-35 mission.

ULA Vulcan: 'No significant issues' thus far

The first United Launch Alliance Vulcan rocket sits on the pad at sunset Friday at Launch Complex 41 at Cape Canaveral Space Force Station.

Update 9:43 p.m.: In a series of updates, ULA officials are describing the ongoing rocket-fueling process. The following post provides a synopsis:

"This is Vulcan Launch Control as we enter the final five hours until liftoff of the inaugural flight of United Launch Alliance's new rocket. We are loading liquid oxygen into the Centaur V upper stage and active with preps on the other three commodities for tanking the launch vehicle tonight," the post said.

"No significant issues are being addressed in the countdown and weather conditions remain in our favor for launch at 2:18 a.m. EST (0718 UTC) from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida."

Vulcan liquid-oxygen fueling begins

Update 9:13 p.m.: From ULA: "With the thermal conditioning, or chilldown, now complete, liquid oxygen has started to flow into the Centaur V upper stage for today's launch.

"For this 271st flight of Centaur, the upper stage will perform three burns during launch to achieve a parking orbit, a high-energy transfer orbit for Peregrine and an Earth-escape trajectory into deep space for the non-deployable Celestis memorial payload."

Tonight's launch countdown resumed on schedule about a half hour ago.

Update 8:28 p.m.: ULA officials just announced that the Vulcan countdown has entered the first of two planned holds.

As a reminder, here is what Gary Wentz, ULA vice president of government and commercial programs, said during a Friday pre-launch press conference:

"We'll complete some of the initial preparations and then clear the launch complex at L-minus-6 hours. At L-minus-5? hours, we will start the chill-down in preparation for cryogenic tanking. And that'll conclude with a complete tanking around L-minus-2 hours," Wentz said.

The first countdown hold "ensures all steps in the procedure prior to cryogenic propellant loading are complete and satisfactory before the start of tanking," a ULA blog post said.

ULA: 'Teams are working no issues'

Update 6:27 p.m.: New tweet from ULA: "The #VulcanRocket countdown is proceeding on pace. Final system preps and testing procedures are underway as we continue to target liftoff at 2:18amEST (0718 UTC) to put @Astrobotic's Peregrine lunar lander on its course to the Moon.
