These were the 6 launches of my models of the @ESA launcher #Ariane6 (made by @ArianeGroup) & #Vega (by @Avio_Group), and the @ulalaunch #AtlasV - for the first educational #MoonDot mission of @JrAstronautin! #minilaunchers 🚀 #STEMed #STEAM Full HD: youtu.be/BhWW1n1kBSM

Start your week with some new photos from Artemis II! Though our journey around the Moon has ended, we're still retrieving plenty of new images. Keep an eye on our Artemis II multimedia gallery for image highlights from the mission: go.nasa.gov/4usiN8W

Artemis III hardware is taking over at @nasakennedy! The SLS core stage for the mission arrived via barge this week - but segments of the twin solid rocket boosters began making their arrival on April 13. Read about these recent arrivals: go.nasa.gov/3QJkUXi

(Re)Discover mission VA268's highlights! 🚀 On April 30, Ariane 6 successfully launched 32 Amazon Leo satellites in its Ariane 64 configuration, the most powerful version of the launcher, with Arianespace as launch operator. This mission once again demonstrates the performance and versatility of Ariane 6. 📸 Take a closer look at this exceptional launch through our selection of photographs. What was your favourite moment of mission VA268? @Arianespace @Amazonleo @esa @CNES @EuropeSpacePort #RocketMakers #Ariane6 #VA268

@Sardor99 @DLR_SpaceAgency @rprogge @derspiegel Ist schon richtig! Wer durch die Qualifikation "Bekannte eines Milliardärs" ins All kommt ist doch bestenfalls eine "Private Raumflugteilnehmerin", nichts weiter. Und wenn das DLR damit Werbung macht, dann ist das nur billig, um vom Versagen in den letzten 30 Jahren abzulenken.

@DLR_SpaceAgency @rprogge Für den Spiegel ist @rprogge ja keine richtige Astronautin! Nimm das @derspiegel !!🖕 spiegel.de/wissenschaft/r…

Die erste Deutsche Astronautin @rprogge hat uns heute in Bonn besucht. Danke für den inspirierenden Vortrag und die fantastischen Einblicke in deine #Fram2 -Mission! Und danke für das signieren deines Portraits für unsere Astronauten & Astronautinnen-Galerie!

A successful second launch for Amazon Leo with Ariane 6. 🚀 On April 30, 2026, Arianespace successfully launched and deployed 32 Amazon Leo satellites into low Earth orbit aboard Ariane 6 in its most powerful Ariane 64 configuration, from Europe’s Spaceport in French Guiana. The mission, designated VA268 and LE-02 by Amazon Leo, was completed successfully in 1 hour and 54 minutes, with all satellites accurately delivered to orbit. This second Ariane 6 launch for Amazon Leo marks another key milestone in the deployment of the constellation, within a series of 18 missions. With this success, Ariane 6 confirms its full operational capability and its ability to meet the demands of large-scale constellation deployments. A new step forward for Europe’s heavy-lift launcher. ✨ Discover more in our press release: press.ariane.group/arianespace-su… #RocketMakers #Ariane6 #VA268 @Amazonleo @Arianespace @esa @CNES @EuropeSpacePort

Busy day at Kennedy Space Center! 🚀 ☑️ Artemis III core stage moved into the Vehicle Assembly Building for integration ☑️ Solid rocket booster segments for Artemis III continue early processing and integration work ☑️ Artemis II Orion capsule is back at Kennedy to undergo post‑flight analysis Momentum is building, as we prepare for the next giant leap! go.nasa.gov/4vWJ2px

The core stage for the Artemis III rocket has arrived at @NASAKennedy. Watch teams offload this crucial piece of hardware for the mission that will test rendezvous and docking necessary for future crewed landings on the lunar surface: youtube.com/live/oWe8kvpxz…

The launcher is complete, all systems are ready and the countdown is on! ⚡️ Flight #VA268 will take 32 @Amazonleo satellites from @EuropeSpacePort in French Guiana to low Earth orbit. Liftoff is set for 30 April 2026 between 09:08-09:57 BST/10:08-10:57 CEST. @Arianespace is the launch service provider, @CNES maintains the Ariane 6 launch facilities at @EuropeSpacePort. 🎥 Video editing: @esa 🎞️ Video footage: @ESA @CNES @ArianeGroup @Arianespace

“Every single thing that we learned on ISS is up here." - @Astro_Christina For over 25 years, the station has provided a platform for sharpening the skills, tech, and knowledge needed to thrive on journeys to the Moon and beyond. More: go.nasa.gov/4q3X59Z

That feeling when your package finally shows up. 📦🚀 After a 900-mile trip from Michoud Assembly Facility in New Orleans, @NASA's Pegasus barge has arrived at Kennedy with the @NASAArtemis III SLS (Space Launch System) core stage aboard. Tomorrow, teams begin offloading and moving the 212-ft core stage into the Vehicle Assembly Building. go.nasa.gov/4mUbe8l

Update: RFA has submitted its application for the marine license for Test Flight 1 from @SaxaVord_Space. For the first time, the application also specifies a potential launch window, which will open NET (no earlier than) July 1, 2026. This is a legally required step for planning, and a good sign of how far we’ve come - but it’s not a launch date just yet. We applied for this window because we’re working hard to be ready - and we’re getting closer every day. So: the application means we’re entering a new phase of preparation. Still, as with any first-ever launch, there are uncertainties, and the schedule may evolve. Further specific details around launch timing will be released through the appropriate channels closer to the time. We’ll keep you posted! 🚀

ESA has confirmed corrosion issues with HALO and I-HAB but pushed back against claims that these were the primary cause of delays to the station's development europeanspaceflight.com/esa-sheds-ligh…

Artemis II represented a team of people across NASA’s centers and beyond who came together to support the four astronauts aboard and complete a successful mission. Tomorrow at 3:30pm ET (1930 UTC), our experts will be on @Reddit to take your questions: reddit.com/r/nasa/

Day 068, orbit 1054 — Opening the shutters in the morning: what a beautiful way to start the day! 🌍 🎥 NASA/ESA #εpsilon • @esa • @esaspaceflight • @Space_Station • @NASA • @NASA_Johnson •

@esa @NASAArtemis @AirbusSpace @csa_asc @esaspaceflight What a wonderful mission! We can't wait until an @esa will take part in an #Artemis mission! #Btw, are you looking for an #Artemis #SLS model for your desktop or to fly it, please have a look here: raketenmodellbau-klima.de/Neu.htm?a=cata… #ESA #ESM #NASA #ArtemisII #modelrockets #STEMEd

Artemis II just took humankind farther than ever before. 🚀 Our European Service Module sent Orion around the Moon and safely back home, providing power, propulsion and life support for the crew. Relive the mission with our highlights video.👇

Is this the #ArtemisII #Orion capsule? No. It's even better: this is the very 1st Orion capsule that was in #space in 2014 during the #EM1 mission! I visited @nasakennedy with my buddy @StuartMcclung 9 years ago. Thank you so much Stu! #STEMEd #Artemis #MoonDot 🌒 #ESA #NASA
