Artemis III is taking shape 🚀 From the Orion spacecraft coming together to key SLS (Space Launch System) hardware reaching important milestones, the past month has brought major progress across the board for the next Artemis mission. Read more: t.co/lMjxMzGImy 🔗 go.nasa.gov/4xqqaPJ

Engineers at @NASAAmes have been working with @SpaceX on a test series to better understand the extreme aerodynamic forces the Super Heavy Version 3 rocket booster can experience during re-entry as we prepare for Artemis III. Read more: t.co/uDSK6135xn 🔗 go.nasa.gov/4yUqjMR

Delivered! 📦 NASA delivered a mini navigation receiver to Intuitive Machines for integration onto their upcoming Altus-1 lunar relay. These relays will enable communication with missions exploring the lunar South Pole and far side of the Moon. Learn more: 🔗 go.nasa.gov/3TxlPvn

It’s National Intern Day — learn about one of our interns who is bringing our Artemis missions into sharper focus. As an intern at @NASAJohnson, Alex Gregor analyzes and calibrates cameras for the optical navigation system used on Orion and other spacecraft.

Tonight, take a moment to look up and enjoy one of nature's timeless sights: a full Moon. Beautiful, familiar, and endlessly inspiring, the Moon never loses its ability to fill us with wonder.

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.

🌕 Happy International Moon Day! On this day in 1969, Neil Armstrong took humanity's first steps on the Moon. Today, through the Artemis program, we're building on that legacy. Together, we're shaping the future of deep space exploration, one mission at a time.

Exploration Ground Systems teams in the Rotation, Processing, and Surge Facility at @NASAKennedy are preparing the SLS (Space Launch System) booster segments for stacking! The right center forward segment is one of 10 motor segments that will make up the 177-foot... 🔗 x.com/NASAArtemis/status/20...

Get ready for a front row seat to Artemis III. NASA has selected @SpaceX to provide laser communications capabilities from the Orion spacecraft for the mission. They will deliver high-def imagery as astronauts test rendezvous & docking operations between Orion and commerci... 🔗 go.nasa.gov/4pJGMzn

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. Learn more about these landers here >> t.co/j1WPaBQ70f 🔗 go.nasa.gov/4bG9yuz

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.

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.

🎮 Artemis III: Loading... From hardware deliveries to key milestones, progress toward our next mission is moving full speed ahead with SLS hardware arriving at @NASAKennedy. Stay in the game with recent updates as we prepare for Artemis III. t.co/aGAmweeaB2

Ready for even more Moon joy? Try International Observe the Moon Night 🌓 This Sept. 19, you’re invited to celebrate our nearest neighbor in space with lunar observers and curious people all over the world. Register: t.co/nyhsbPRlln 🔗 go.nasa.gov/ObserveTheMoon

Look up tonight! The Strawberry Moon reaches peak fullness at 7:56pm ET (2356 UTC). Despite its name, the Moon won't actually look pink or red! It's called the Strawberry Moon because many Native American tribes used this full moon to mark the strawberry harvest season.

Artemis III is coming together, piece by piece. The second of four RS-25 rocket engines was recently offloaded at @NASAKennedy. These rocket engines will power the Space Launch System rocket during the launch of Artemis III, propelling the Orion spacecraft into Earth orbit.

Memories inside Orion! The Artemis II mission ended over two months ago, but we’re still over the Moon. Please enjoy these previously unreleased images from the Artemis II mission.

Did you send your name with Artemis? Here's your chance to send your name a million miles away from Earth aboard the Roman Space Telescope, currently slated to launch on Aug. 30. 🔗 twitter.com/i/status/206763...

Can you work out like an Artemis astronaut? The Artemis II astronauts exercised for roughly 30 minutes per day during their mission with a device called the flywheel, which provides the crew with a range of workouts without requiring any electrical power from the spacecraft.

During their lunar flyby, the Artemis II crew enjoyed the rare opportunity to experience a solar eclipse from their Orion spacecraft. With the Sun hidden behind the Moon, the astronauts were able to analyze the Sun’s outermost atmosphere, also known as the solar corona.

Big week for Artemis III 🚀 Just before NASA introduced the Artemis III crew, the SLS solid rocket booster segments arrived in Florida after a six-day rail journey from Utah. Later this year, teams will begin stacking the boosters that create 75% of the thrust needed at launch.

Behold: new and previously unseen imagery from our Artemis II mission! These images were captured on April 6, 2026, when the four astronauts aboard the Orion spacecraft conducted the lunar flyby portion of their ten-day journey.

One week to go! 🚀 @NASA will announce the Artemis III crew on June 9 at 11am ET (1500 UTC). Get ready to meet the four astronauts who will help advance the technologies needed to return humans to the Moon. More: t.co/AbNqKsLcvh 🔗 go.nasa.gov/4wV6Muy

Want to fly a CubeSat aboard a future Artemis mission? The Space Launch System rocket provides an opportunity to deploy science and technology investigations into space. Interested organizations should respond to NASA's request for information by June 1: t.co/7w4daZQbAC 🔗 go.nasa.gov/4a27H2m

POV: You’re coming home after a journey around the Moon. 🌕 Before reentering Earth’s atmosphere at the end of Artemis II, the Orion spacecraft’s crew module — carrying the astronauts — separated from the service module that provided propulsion and power throughout the mission.

NASA is seeking industry collaboration for the Mars Telecommunications Network. Reliable, high-bandwidth connectivity will enable future Red Planet explorers to send science data, imagery, and critical mission information to Earth. Learn more: t.co/MM4CfV8a9Q 🔗 go.nasa.gov/3R17eXU

NASA is preparing to dock with commercial landers in Earth orbit with Artemis III in 2027 and send astronauts to the Moon with Artemis IV in 2028. Check out the full-scale prototype of @BlueOrigin’s Blue Moon Mark 2, now at @NASA_Johnson. t.co/zo3rsbewsJ 🔗 go.nasa.gov/4txPtN6

Life inside Orion! The Moon joy was (and continues to be!) contagious as the Artemis II mission flew around the Moon and broke the record for farthest distance traveled from Earth.

During the Artemis II mission, astronauts had a fun time playing around with water in the weightlessness of space. Artemis II was @CSA_ASC astronaut @Astro_Jeremy's first spaceflight — so his crewmates taught him a lot about the physics of water in space.
