After moving the ARCHIVED: NASA_SLS core stage north in the Vehicle Assembly Building transfer aisle, teams began lifting it with two of the facility’s overhead cranes, reorienting it into a vertical position. This is called a “breakover.”

United Launch Alliance is readying the formidable #AtlasV 551 rocket to deliver the first production satellites into space for #Amazon's #ProjectKuiper. Learn more about #Kuiper1 preparations in our preview blog: blog.ulalaunch.com/blog/kuiper-1-…

We’re going! 🌖🚀 Meet the astronauts who’ll be the first to fly under NASA’s #Artemis mission! They’ve just unveiled their official mission patch. Check it out and learn more about their historic journey: go.nasa.gov/4cn6hzN

Artemis II honors all.

NEW LAUNCH TIME. ULA Launch Director Eric Richards has instructed the team to coordinate a new target launch time of 7:40 p.m. EDT (2340 UTC) in hopes weather will improve. bit.ly/av_kuiper1

Employees at NASA Marshall got a sneak peek of the Orion stage adapter for Artemis II and III. The adapter is the final piece of SLS hardware that will soon make its way to NASA's Kennedy Space Center, marking continued progress towards the stacking of the rocket. 🔗 go.nasa.gov/3Rh6gUd

Recently, mobile launcher 2 reached new heights with the installation of tower module 6. This towering structure is a key piece of future Artemis missions, built to support the powerful SLS rocket in its Block 1B configuration starting with Artemis IV. 🔗go.nasa.gov/3Y8fAxD

Vandenberg Guardians and Airmen supported an operational test launch of an unarmed Minuteman III ICBM on May 21 at 12:01 a.m. PT. This test validates the safety and readiness of the weapon system. #MinutemanIII #GT253

The results are in! 🏆 The 2024 NASA Pictures of the Year have been announced. Congratulations to all the winners, and to Artemis — which was represented heavily in the images!

🔌Powered up!⚡ Last week, Exploration Ground Systems teams powered up the NASA Artemis II NASA_SLS core stage and solid rocket boosters for the first time. Teams in NASA's Kennedy Space Center’s Launch Control Center verified the systems and interfaces function between the flight hardware

We’ve built 1.3M+ solid rocket motors and we’re just getting started. 🚀 From space launches to missile defense, propulsion drives it all and we’re scaling fast to meet mission needs. See how we’re propelling the future at ms.spr.ly/6014SmDxi

On June 26 at 1pm ET, we are static test firing the Booster Obsolescence and Life Extension solid rocket motor – the largest segmented solid rocket booster ever built.

#GEM63 solid rocket booster burnout and jettison is confirmed for the #AtlasV 551, having consumed a half-million pounds (227,000 kg) of propellant to augment the initial liftoff thrust. The launch vehicle continues towards orbit on the power of its main engine and will more than

Congrats ULA ! 🚀🚀🚀

We’ve tested the world’s largest and most powerful solid rocket motor ever built for human spaceflight. Known as Booster Obsolescence and Life Extension (BOLE), the 156-foot-long motor produced upwards of 4 million pounds of thrust. news.northropgrumman.com/launch/Northro…

One of the most inspiring moments in human history NASA astronaut Neil Armstrong’s words echoed across the world #OTD in 1969 as he became the first person to set foot on the surface of the Moon. The culmination of years of united effort, the Apollo 11 Moon landing remains a

Liquid hydrogen propellant is now flowing into the Centaur V upper stage for launch. This is the final tank to be loaded during today's #VulcanRocket #USSF106 countdown. We have a green board with no issues being addressed by the ULA launch team. bit.ly/vulcan_ussf106

The versatile Vulcan rocket combines the best of legacy Atlas V and Delta IV Heavy into a single-core rocket to support U.S. national security, commercial and civil launch needs. Today we are flying the VC4S variant that stands 202 ft. tall and generates three million lbs. of

Going farther, without forgetting how far we’ve come.
