"The commercial space industry moves at a rapid pace, and NASA Stennis has cultivated a forward-leaning culture built on providing solutions to match that pace," said NASA Stennis Director Christine Powell. "We welcome Cowboy Space to NASA Stennis and look forward to supporting their propulsion testing needs."

Later this year, we're heading to NASA Stennis Space Center to conduct propulsion testing at America's largest rocket propulsion test site.

We will be conducting a comprehensive propulsion test campaign to gather critical flight data.

This testing will directly inform our integrated launch system, the vehicle that will eventually place solar-powered AI data centers in low Earth orbit.

More to come soon.

Great missions start with great people.

NASA Force is bringing together exceptional engineers to solve some of the toughest technical challenges in exploration. If you want your work to help return Americans to the Moon, build the @NASAMoonBase, and prepare for Mars, this is your opportunity.

Ray Williams’ progression at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, has uniquely prepared him for his new role.

As part of NASA’s plan to restore core competencies by converting contractors to civil service, the New Orleans native and Grambling State University graduate now works as a supervisor for test operations support at the agency’s E-Complex.

@NASA and @BlueOrigin announced Friday they recently agreed to conduct second stage hot fire testing for the company’s New Glenn rocket on the B-2 test stand at the agency’s Stennis Space Center near Bay St. Louis, Mississippi.

The annex to a reimbursable Space Act Agreement signed earlier this month highlights NASA’s commitment to working alongside commercial partners toward @NASAArtemis missions in 2027 and beyond.

@SenHydeSmith Thank you for your support 🇺🇸

[NASA Artemis @NASAArtemis]

Roadtrip complete ✅

After departing @NASAStennis, the fourth and final RS-25 engine for @NASA's SLS rocket has arrived in Florida.

Now reunited with the other Artemis III engines, the powerful quartet is almost ready for installation at @NASAKennedy.

[NASA Moon Base @NASAMoonBase]

Moon Joy(rides), anyone?

NASA has selected @Astrolab_Space and @LunarOutpostInc to provide the first fleet of lunar terrain vehicles that will help @NASAArtemis astronauts explore the Moon.

Built for the rugged terrain of the lunar South Pole, these next-generation rovers will help crews travel farther, explore longer, and help lay the groundwork for humanity's first Moon Base.

[NASA Artemis @NASAArtemis]

Before Artemis astronauts land on the Moon, NASA is conducting the Artemis III demonstration mission in low Earth orbit to practice operations between commercial human landing system test articles and Orion.

NASA Stennis is proud to have tested the RS-25 engines that will power the Artemis III mission! 🚀

It is great to see the third engine safely arrive at @NASAKennedy for integration.

[NASA Artemis @NASAArtemis]

Just a regular ol' rocket engine!

The third of four RS-25 rocket engines have arrived to @NASAKennedy to be integrated into the Artemis III rocket. Space Launch System uses four RS-25 engines to propel the Orion spacecraft, providing over two million pounds of thrust at liftoff.

[NASA Artemis @NASAArtemis]

The pieces for Artemis III are coming together at @NASAKennedy.

The twin solid rocket boosters? They’re getting stacked.

The launch team? They’re simulating the countdown.

The heat shield? It’s now attached to the Orion spacecraft.

Full steam ahead for Artemis III.

[NASA Administrator Jared Isaacman @NASAAdmin]

Happy 250th birthday America! As a nation, we have so much history to celebrate, and at @NASA, we are just getting started. God bless the USA 🇺🇸

[Bethany Stevens @NASASpox]

On America’s 250th birthday, @NASA is helping write the next chapter of exploration 🇺🇸

🌕 New Moon Base missions announced
🤝 Growing America's space industry & NASA’s workforce

Welcome to NASA!

To start this week, 120 new civil servants were sworn in at NASA’s Stennis Space Center as part of the @NASAAdmin's initiative to strengthen our core competencies and enhance mission agility.

Strengthening our core competencies ensures we responsibly steward taxpayer resources, align our investments with agency priorities, and deliver on our mission in support of the National Space Policy.

These talented professionals will help drive mission success and advance America’s leadership in space.

HAPPENING TODAY: Meet the Artemis III astronauts 🚀

[NASA @NASA]

UPDATE: The Artemis III event will start at 11:30am ET (1530 UTC) on Tuesday, June 9!

[NASA @NASA]

Tomorrow, we're announcing the astronauts flying aboard Artemis III, the mission that will test rendezvous and docking capabilities with commercial lunar landers in low Earth orbit.

If you could ask the Artemis III astronauts any question, what would you ask them?
