Four astronauts. One mission.
Hear from the crew of Artemis II, who are preparing for humanity's next lunar journey, in the newest episode of our "NASA's Curious Universe" podcast: bit.ly/498S0qf
LIVE: Tune in for a change of command ceremony aboard the @Space_Station. Cosmonaut Sergey Ryzhikov, who will return to Earth later this month, is handing over command of the station to NASA's @AstroIronMike.
We've got you loud and clear and standing by to say hi! 📞 Next year the crew aboard the station will have the opportunity to take part in a ship-to-ship call with the four humans inside the Orion spacecraft "named Integrity" as they travel to the Moon as part of @NASAArtemis II.
What secrets do lunar rocks hold? Artemis is ready to find out.
Meet AIRES, a spectrometer that measures infrared light to reveal what the Moon’s rocks and soils are made of.
This took a few takes to capture . . . Initially held onto the camera mounting bracket and pushed off (you can hear the bracket clinking). Then carefully let it go so the camera floats with you through space station. Flew from the aft end of the lab to the forward end of Node 2.
The Artemis II crew recently completed three days of testing and training inside the Orion spacecraft at @NASAKennedy. They performed suit fit and leak checks, communication checks, interfaced with equipment, and simulated launch and flight scenarios. go.nasa.gov/40SpXXI
ISS Expedition 73 in the house! Just got here yesterday, felt so very familiar, like I never left. Spending time getting reacquainted with my friends and the @Space_Station. Very glad to be here.
Just. Wow. As we went over Mexico and the U.S. this morning, I caught this sprite.
Sprites are TLEs or Transient Luminous Events, that happen above the clouds and are triggered by intense electrical activity in the thunderstorms below. We have a great view above the clouds, so scientists can use these types of pictures to better understand the formation, characteristics, and relationship of TLEs to thunderstorms.
Wow. What a day. Spacewalks are grueling and exhilarating all at the same time.
@AstroAnnimal, @astro_berrios, @JonnyKimUSA, @Astro_Onishi, and our flight control team on the ground absolutely set the standard for teamwork. We started the day off more ready than ever thanks to Tak and Jonny’s efforts suiting us up.
We had a dynamic day outside with lots of changes and challenges, but our team got through it all! This was probably the most challenging and rewarding day I’ve ever had.
We got out the door and got the tasks done that make the @Space_Station ready for the next cargo spacecraft, roll out solar arrays, and continued work on science through the next several years.
.@NASA_Astronauts Anne McClain and Nichole Ayers are getting ready for a spacewalk set to begin around 8:15am ET today to upgrade the station’s power generation capabilities live on @NASA+. nasa.gov/blogs/spacesta…
EXCITING! Two #Artemis II Astronauts visited #KSC Jeremy Hansen, Mission Specialist from Canadian Space Agency and Andre Douglas, back-up Mission Specialist gave word of thanks, encouragment and shook everyone's hand. So cool!! #NASA
If you have ever spent time in a school or office building, you have probably experienced a fire drill. Well, astronauts practice emergency drills, too!

It’s been just over a week since our launch. As I reflect, these are the core memories that will stay with me from that unforgettable day:
Watching the suit engineers meticulously check each connection and seal—something I deeply appreciated.
Seeing my friends and family during walkout. My children, smiling behind the glass, playing rock-paper-scissors with me as we waited for the pressure check. Waving our final goodbyes.
Walking up to our rocket and realizing—it’s a living, breathing giant. The gravity of the moment didn’t fully hit me until I saw frosty snowflakes drifting off the supercooled rocket and heard the groans of metal expanding and contracting.
Thinking of my family as I listened to our launch playlist while waiting on the launchpad. Then listening to the engines roar to life, feeling the G-forces slowly building in our chests, and being impressed by how familiar it all felt—the launch, ascent, and orbital insertion—like another sim or centrifuge run. A true testament to the depth and excellence of the training we received.
And then there it was, the International Space Station. A shining cathedral of metal, floating just beyond our window on final approach.
Reuniting with our friends from MS-26 and Crew-10 after hatch opening was a moment of pure joy.
Life aboard the ISS has been busy adjusting to the new environment and learning how to contribute to the mission. This national laboratory above our planet is alive with science, discovery, and purpose, and I’m excited to share it with you over the next eight months.
One spacewalk comin' right up. 🧑🚀
NASA is hosting a news conference from Johnson Space Center in Houston tomorrow, April 24, at 2 pm EDT to discuss @Astro_Ayers and @AstroAnnimal's upcoming spacewalk next week. Got questions? Use #AskNASA. Tune in: go.nasa.gov/3RqJ6ed
The Artemis II crew had a busy week as always – mission simulations, exciting Webby nominations, and the unveiling of the Artemis II mission patch that signifies we are all going together. Let’s go!
