Members of United Launch Alliance's VALOR room team are coming on duty at this hour in Denver, CO. This elite group of ULA specialists will serve as an ascent flight control team during launches of @BoeingSpace’s #Starliner spacecraft aboard #AtlasV rockets.

#AtlasV fun facts #Starliner // #CFT Height: 172-foot-tall (52 meters) Mass at liftoff: 979,000-pound (444,000-kg) Thrust: 1.6 million pounds (7.1 megaNewtons) Webcast: bit.ly/av_cft

#AtlasV fueling operations have been initiated. The first step in tanking procedures is loading 4,150 gallons of liquid oxygen into the Dual Engine Centaur upper stage for today's #CFT mission. Don't miss a thing by following along in our blog: bit.ly/av_cft

The countdown is proceeding and we are GO to fuel the #AtlasV rocket with 66,000 gallons of liquid oxygen and liquid hydrogen. ULA Launch Director Tom Heter III authorized cryogenic tanking operations as the countdown moves forward. Fueling updates: bit.ly/av_cft

Good day from #AtlasV launch control where our blog has started for tonight's historic Crew Flight Test launch of @BoeingSpace's #Starliner carrying two veteran astronauts. This is your official source for updates throughout the ULA countdown to launch. bit.ly/av_cft

In the first briefing of the countdown, the launch weather team tells mission managers that the forecast for launch of #AtlasV and #Starliner #CFT remains at a 95 percent chance of acceptable conditions for liftoff tonight at 10:34pmEDT (0234 UTC). bit.ly/av_cft

#ToryTalk // ULA President and CEO @ToryBruno explains how ULA's #AtlasV, one of the most reliable rockets in the world, carries an extra layer of safety for its solemn duty of launching astronauts on the #Starliner #CFT mission.

Our engineers at @NASAKennedy powered up and activated #Starliner. Meanwhile, @ulalaunch teams loaded the Atlas V first stage with 25,000 gallons of RP-1 fuel. Both vehicles are healthy for launch on May 6 at 10:34 p.m. ET. Learn more: starlinerupdates.com/starliner-powe…

🚨 An Atlas V 🚀 with The Boeing Starliner Capsule CST-100 carrying the NASA crewed Mission named "Crew Flight Test (CFT)", is fuelled and all ready for Monday's launch. #Space #NASA #Boeing #Starliner #AtlasV #SpaceX #RCBvGT #StarWars Liftoff of the Starliner aboard a…

The joint ULA, @BoeingSpace and @Commercial_Crew team completed all of today's planned activities for rollout day and powered down the #AtlasV rocket. The next event will be starting the countdown Monday morning. bit.ly/av_cft

#Starliner and #AtlasV have rolled to @ulalaunch's Space Launch Complex-41 launch pad. Teams moved the 172 ft (52 m) tall stack at ~1 mph (1.6 kph). Roll to pad is a major milestone ahead of the May 6 Crew Flight Test launch with @NASA_Astronauts Butch Wilmore and @Astro_Suni!

The Crew Access Arm has been extended to the #Starliner and #AtlasV stack at Space Launch Complex-41. Pad and operations teams will conduct final checks before launch on May 6 at 10:34 p.m. ET.

#AtlasV will launch #Starliner on its Crew Flight Test to rendezvous and dock with the @space_station, where astronauts Butch Wilmore and Suni Williams will live and work for about a week before returning to Earth to land at a site in the Western U.S. bit.ly/av_cft

This launch is bridging the distinguished history of Atlas rockets. The first orbital spaceflights of American astronauts in the 1960s were launched by Atlas, now #AtlasV will support @BoeingSpace in @NASA's @Commercial_Crew collaboration. bit.ly/av_cft

#MayThe4th be with #Starliner today as it rolls to the launch pad atop #AtlasV! Get yourself ready for the mission with this look back at Starliner's rollout from our factory to @ulalaunch's Space Launch Complex-41, which happened mid-April.

Three days and counting until the launch of #Starliner's Crew Flight Test! Stay tuned as Starliner and #AtlasV roll to the launch pad tomorrow, May 4. #NASASocial

Next up at the #NASASocial, ULA's Caleb Weiss, System Engineering and Test Leader joins a panel of experts to discuss Monday's #AtlasV #Starliner #CFT launch! @BoeingSpace

Welcome #NASASocial crew to the Advanced Spaceflight Operations Center (ASOC)! We are excited to show you the Launch Control Center (LCC) today ahead of the #AtlasV #Starliner #CFT launch! @NASASocial @BoeingSpace

The names of Wilmore and Williams will soon join Glenn, Carpenter, Schirra and Cooper as pioneering astronauts to launch atop Atlas rockets from Cape Canaveral. Meet the first #Starliner astronauts launching Monday atop #AtlasV: blog.ulalaunch.com/blog/cft-meet-…

Wondering when and where you may see the #AtlasV #Starliner #CFT launch? The visibility map shows your best chances to see the rocket along the eastern seaboard of the U.S.! Launch is scheduled for May 6, 2024 at 10:34 p.m. EDT from Cape Canaveral, FL. bit.ly/av_cft

Check out the mission profile video to learn how ULA’s #AtlasV rocket will launch @BoeingSpace's #Starliner #CFT mission for @NASA's @Commercial_Crew Program.

ULA uses a unique version of its #AtlasV countdown for human spaceflight missions, in the name of safety, to complete fueling operations and then place the rocket in a quiescent state before the astronauts board. Learn more about Monday's #CFT schedule: blog.ulalaunch.com/blog/cft-a-pre…

As we return human spaceflight to Atlas, our #ULARocketStars pass the torch of knowledge to future generations, building on all we have learned. Go Atlas! Go Centaur! Go Starliner! #AtlasV #Starliner #CFT

We are less than 1 week until launch! Have you downloaded the #AtlasV #Starliner paper model kit yet? Download at the link below! 🚀 bit.ly/44mOd4E

Earlier this week, our teams rolled #Starliner out of our factory at @NASAKennedy and over to @ulalaunch. There, Starliner was placed atop an #AtlasV rocket ahead of its May 6 launch. Learn more from the teammates who worked together to make it happen: onfirstup.com/boeing/BNN/art…

#Starliner then trekked by the Merritt Island National Wildlife beach and arrived at @ulalaunch’s Vertical Integration Facility. Here, teams integrated Starliner to the #AtlasV rocket that will launch the spacecraft and its first crew to orbit on their way to @Space_Station.

The @BoeingSpace #Starliner spacecraft is mounted atop its ride to space—ULA’s #AtlasV rocket—in preparation for launch of #CFT in collaboration with @NASA's @Commercial_Crew Program. Learn more in our blog: bit.ly/4awGT8O

We were thrilled to have @Commercial_Crew Astronauts @AstroIronMike, @Astro_Maker1, Butch Wilmore and @Astro_Suni at spacecraft integration this morning. ULA is proud to launch the #Starliner Crew Flight Test (#CFT) on #AtlasV for @NASA and @BoeingSpace.

#Starliner has been securely integrated with the #AtlasV rocket, which will fly @Astro_Suni and Butch Wilmore to @Space_Station on the Crew Flight Test. Thanks to @ulalaunch for helping to accomplish this important step toward launch. More: starlinerupdates.com/starliner-roll… 📸: ULA

#Starliner is ready to roll. Our teams have completed final checks, and Starliner will begin its 10-mile journey to the @ulalaunch Vertical Integration Facility momentarily. There, the spacecraft will be stacked atop #AtlasV ahead of its May 6 launch.

Today, teams will roll #Starliner out of our factory at @NASAKennedy to be stacked on a @ulalaunch #AtlasV rocket. This is a significant step toward the May 6 Crew Flight Test launch, when Starliner will carry Butch Wilmore and @Astro_Suni to the International Space Station.

#Starliner is now loaded onto the transporter that will roll it out of our factory tomorrow, April 16. It will head to @ulalaunch's Vertical Integration Facility to be integrated with the #AtlasV rocket for the Crew Flight Test launch on May 6. More: starlinerupdates.com/starliner-roll…
