@NASAStennis helped power America to the Moon during Apollo, and it has an important role to play as we return to stay. We heard directly from the workforce and visited the historic B-Test Complex, where @blueorigin will test New Glenn’s upper stage through its agreement with NASA. Putting world-class American infrastructure to work with commercial partners is how we move faster, strengthen our industrial base, and stay ahead. We also met with @USSOCOM leadership and watched Naval Special Warfare’s Special Boat Team 22 conduct an impressive hot extraction demonstration. Incredible capability and professionalism on display. A great reminder of the extraordinary people and capabilities behind American leadership on Earth and beyond.

High school & early college students are invited to join experts from @NASAStennis for a live virtual session about hands-on technical careers that support the agency’s mission to the Moon & beyond! 🚀 📅 Registration closes Sept. 21. Sign up here:

Celebrating 65 Years: The 1980s On October 25, 2026, we hit a major milestone – 65 years since NASA announced it would build a rocket propulsion test site in Hancock County, Mississippi. History is still being written today as NASA progresses forward with the Artemis program to return American astronauts to the Moon and build a Moon Base to support an enduring human presence on the lunar surface. This look back at the 1980s features: ➡️ Naming the site to its current name ➡️ Test operations supporting Space Shuttle Program ➡️ Community outreach activities

The attacks of Sept. 11, 2001, were a national tragedy that resulted in a staggering loss of life and a significant change in American culture. Each year, we pause to remember.

NASA Stennis Director Christine Powell, right, participates in a panel discussion during the Mississippi Aerospace and Defense Symposium on Sept. 4. in Flowood, Mississippi. The conversation focused on collaboration between government entities such as the Department of War, and related federal partners, in operation at NASA Stennis. Pictured with Powell, left to right: Jace Ponder, director, Governor’s Office of Military Affairs, Mississippi Development Authority (moderator); Dr. William Burnett, Director, National Data Buoy Center; Dr. Joe Calantoni, Senior Executive Service Technical Director, U.S. Naval Meteorology and Oceanography Command. The annual symposium is co-hosted by Mississippi Enterprise for Technology and Defense Alliance of Mississippi. It brings together industry, government, academia, and defense leaders to talk about aerospace, defense, space technology, workforce, and economic development in Mississippi. NASA Stennis is America’s largest rocket propulsion test site and functions as a federal city with tenants supporting a wide range of missions, from propulsion testing to information technology and oceanography. The U.S. Navy has a significant presence here, and several aerospace and technology companies and agencies are also located at NASA Stennis.

Artemis II crew brings Moon Joy to NASA Stennis! 🚀 NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen visited us on Thursday, Sept. 3, to celebrate the historic @NASAArtemis II test flight around the Moon. As the first astronauts to fly aboard NASA’s Orion spacecraft, the crew traveled farther in space than humans have ever before. During their visit to Stennis, they stopped at the Fred Haise Test Stand, where rigorous RS-25 engine testing ensures our astronauts fly safely on NASA’s SLS rocket. The crew thanked everyone for tackling hard challenges and reminded us during an employee event: “You put humans in space.” Today provided a great reminder for all: Whether you work at America’s largest rocket propulsion test site or look up at the Moon from your backyard, you are a part of America’s return to the Moon. And the Artemis II mission is just the beginning! Next comes Artemis III with a mission intended to demonstrate integrated operations between the Orion spacecraft and test versions of commercial human landing systems before Artemis IV returns astronauts to the lunar surface.

This look back at the 1960s features: ➡️ President John F. Kennedy setting the national goal of sending humans to the Moon and returning them safely ➡️ Site construction to begin Mississippi’s largest construction project at the time ➡️ Saturn V rocket stage testing that carried humans to the Moon during Apollo

Ad astra ⭐ At 7:26am ET (1126 UTC) on Aug. 30, @NASARoman took to the skies en route to its new home 1 million miles away from Earth. It should reach its final destination in one month:

Getting our cameras ready for Artemis III🚀 A July test fire of a hydrogen burn-off ignitor at NASA Stennis is providing data for the agency to dial in the perfect camera settings for the @NASAArtemis III launch in 2027. Artemis III is intended to demonstrate integrated operations between the Orion spacecraft and test versions of commercial human landing systems before Artemis IV returns astronauts to the lunar surface. About 10 seconds before NASA’s SLS (Space Launch System) rocket lifts off from @NASAKennedy, hydrogen burn-off ignitors will safely burn off excess hydrogen gas. Here’s the challenge: This flare, which looks like a firework sparkler during launch, is incredibly bright. Just like you might squint if looking toward the Sun, our high-speed launch cameras, recording at 400 frames per second, can react to intense light by closing its aperture too much. Clear imagery is essential for post-launch analysis, real-time situational awareness during liftoff, and to verify hardware status in the event of a premature engine shutdown. This test provides data so that cameras capture every detail without being overwhelmed by the flare. Learn more about NASA’s Artemis program:

At 17, Jeret Howard raised his right hand to serve his country as a United States Army combat medic in Iraq. This past summer, he raised his right hand again at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Hired as a civil servant under the agency’s workforce directive to restore core competencies by converting contractors to civil service, Howard’s transition from long-time contractor to logistics management specialist represents a continuation of a life dedicated to national service. 🔗Full story:

Here is an update on Blue Origin’s progress at NASA Stennis, where teams are advancing toward second stage hot fire testing for the company's New Glenn rocket. This progress highlight NASA’s commitment to working alongside commercial partners as preparations continue for @NASAArtemis missions in 2027 and beyond.
