NASA Artemis

Artemis II honors all.

Last week, the Artemis II crew spent time at @NASAKennedy with Exploration Ground Systems teams. Then, the crew went for a spin at @NASA_Johnson, practicing egress procedures in the event Orion is overturned at splashdown and cannot be uprighted.

Watch as teams at #NASAMichoud move a liquid oxygen tank for the @NASAArtemis III mission. 🏗️ The massive hardware will form part of the SLS rocket's core stage. Seen here from earlier this month, it was positioned into a production cell in preparation for the next phase of…

Virgil "Gus" Grissom flew the "Liberty Bell 7" into space during the second crewed Project Mercury mission #OnThisDay in 1961. He experienced 5 minutes of weightlessness during his 15-minute suborbital flight.

On July 20, 1969, Neil Armstrong and Buzz Aldrin stepped onto the Moon—and with them, the world took a giant leap. That moment sparked a legacy of exploration that continues today as @NASA and its partners advance toward Artemis II and prepare for the next great frontier: Mars.

Teams at NASA's Michoud Assembly Facility recently lifted the Artemis III liquid oxygen tank into a vertical position. Technicians will now be able to rappel inside and complete internal assembly. This tank is one of five pieces that make up the Space Launch System core stage.

Launch Window? Scrub? Nope, it’s not spring cleaning — it’s rocket science! 🚀 In this episode of “Nerdy Words,” it’s all about the timing. We’re breaking down the lingo behind the launch pad to learn how NASA’s SLS (Space Launch System) navigates the countdown clock. 🕰️

NASA has selected three science instruments to travel to the Moon. These instruments will inform us about lunar minerals and volatiles found on the surface of the Moon as well as potentially locate ice. go.nasa.gov/4nJTPix

The next full moon rises Thursday night—don’t forget to step outside and take a look. 🌕 July’s full moon is known as the Buck Moon. The Algonquin tribes of what is now the northeastern United States gave it that name to mark when male deer, or bucks, begin growing new antlers.

This summer is off to a splash 🌊 Preparations for @Axiom_Space’s future lunar spacesuit testing has kicked off under water at @NASA’s Neutral Buoyancy Laboratory where the spacesuit has been tested underwater in a simulated lunar surface gravity for the very first time.

"It was really cool to see, in that moment of adversity, how the team pulls together." Joe Pavicic, @NASAArtemis operations project engineer, talks about his time in the firing room during Artemis I launch attempts. How teams handled the NO GOs before a successful lift off…

From marine biology to the Artemis control room 🚀🌕 Aaisha Ali is the @NASAArtemis ground control flight lead ensuring systems, simulations, and ground procedures are ready for Artemis II. Read her story: go.nasa.gov/4lnYvJG

Virtual reality 🤝 astronaut training At NASA's Johnson Space Center in Houston, Texas, one lab uses the virtual reality environment to study how astronauts perform on spacewalks. Check out the full video: go.nasa.gov/4lA0Gt4

The Artemis II crew training continues. Last week, the astronauts focused on lunar geology and what sort of information they will be able to glean from looking at the Moon from the window of the Orion spacecraft.

From the Artemis team, happy Fourth of July to all who celebrate!

Happiest of birthdays to Apollo 17 moonwalker Harrison "Jack" Schmitt, who turns 90 today! 🥳 60 years ago, Schmitt was announced as one of NASA's fourth group of astronaut candidates: "The Scientists." Schmitt's geology expertise combined with the unique features of the…

Congratulations to #NASAMarshall's John Blevins, chief engineer for the SLS rocket, for being selected as a 2025 Service to America Medals honoree! 👏 Read more about Blevins and our other honoree from @NASAGoddard, Richard Burns >> go.nasa.gov/3GqCZoc

From coast to coast, thousands of suppliers across the United States are playing a vital role in the Artemis campaign. Learn more about how each of them is bringing us closer to returning humans to the Moon–and exploring beyond: nasa.gov/artemis-partne…
