A defining moment of American exploration. The @America250 emblem is displayed on the twin solid rocket boosters of the SLS (Space Launch System) rocket for the Artemis II mission around the Moon. Launch is scheduled for early next year.

We build the world’s largest single-cast solid rocket boosters ever flown. Four of our GEM 63XL #SRBs propelled @ULALaunch’s #VulcanRocket into orbit, delivering a @SpaceForceDoD payload!🚀 https://t.co/c5y1f6ST1H

On this day in 2011, Space Shuttle Atlantis landed at Kennedy Space Center, completing STS-135, the final mission of the Space Shuttle program.

The 135th and final space shuttle mission launched #OTD in 2011. Atlantis transported 11,600 pounds of supplies and equipment to the International @Space_Station. At mission's end, STS-135 Commander Chris Ferguson said, “We sure hope that everybody who has ever worked on, or

#OTD in 2011, Shuttle Atlantis launched STS-135, the final mission of NASA’s Space Shuttle Program. The crew delivered 8,000+ lbs of supplies to the ISS aboard the Raffaello module. Crew: Commander @Astro_Ferg Pilot @Astro_Doug Mission Specialists @Astro_Sandy & @Astro_Rex

Hello, hello. It's good to be back! 👋🎙️ Wishing the best of luck to @oasis as they return to the stage this evening! 🎸🩵

Happy Fourth of July from Kennedy Space Center! We’re throwing it back to July 21, 2011 – the final landing of Space Shuttle Atlantis. This mission, STS-135, delivered spare parts, equipment and supplies to @Space_Station and was the final flight of the Space Shuttle Program.

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.

@TurkeyBeaver @SpaceX One of my favorite days. Only topped by them coming home safely 🩷

Hard to believe it’s been five years since @SpaceX launched the Demo-2 mission. That day was special on so many fronts. It was the culmination of an eight year grind of designing, testing and qualifying Dragon 2. Then there was the intensity in the lead up to the mission while

Happy Demo-2 Day! Today marks the 5th anniversary of Falcon 9 returning human spaceflight capabilities to the United States

Technicians with @NASAGroundSys recently finished stacking the SLS solid rocket boosters for @NASAArtemis II. Watch as teams in the Vehicle Assembly Building at @NASAKennedy assemble the boosters, which will provide 75% of the thrust needed at liftoff. https://t.co/svaSvlTxEz

Boosters: complete ✅ With stacking of the right forward assembly, the @NASA_SLS solid rocket boosters for the @NASAArtemis II mission are complete. In total, teams with Exploration Ground Systems transported and stacked ten motor segments and two forward assemblies to fully

22 years ago, we tragically lost the Columbia STS-107 crew upon reentering the atmosphere. We will never forget the lives and legacy of Rick Husband, William McCool, Michael Anderson, David Brown, Kalpana Chawla, Laurel Clark, and Ilan Ramon. #NASARemembers

Remembering the crew of STS-107: David Brown, Rick Husband, Laurel Clark, Kalpana Chawla, Michael Anderson, William McCool, and Ilan Ramon On February 1, 2003, the seven-astronaut crew was lost when Space Shuttle Columbia broke apart during re-entry.

Today on our Day of Remembrance, we pay tribute to our fallen heroes—the crews of Apollo 1, Challenger (STS-51L), Columbia (STS-107), and others that have lost their lives while advancing NASA's mission. We work to never repeat the mistakes of the past. https://t.co/QQyDG0JGzK

Progress check ✅ Over the last month, @NASAGroundSys has made significant progress stacking the @NASA_SLS solid rocket boosters for the #Artemis II mission. Now, both boosters stand one aft assembly and one segment tall inside the Vehicle Assembly Building at @NASAKennedy.

The flight that changed it all. #OTD in 1903, the Wright Flyer became the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot.

Two years ago, Artemis I soared into the heavens—setting the stage for humanity's return to the surface of the Moon. This was just the beginning. And through #Artemis, we have leap after giant leap in store.
