This might seem trivial, but it isn't. A rapid succession of images quickly shows exactly how this massive structure can be moved without the slightest risk of sinking or breaking.

Big milestone. Structural qualification is one of those behind-the-scenes achievements that reduces risk long before the first flight. Looking forward to seeing the next round of integrated testing.

Solid milestone. But while private companies push forward, Europe's space sector drifts toward irrelevance without structural change.

Before Vikram-1 could leave for Sriharikota, every major system had to qualify on the ground. This episode goes inside that campaign — the Kalam-1200 static fire, stage separation, payload fairing jettison, full OAM qualification, and more. Test after test, Vikram-1 passed. #JourneyToOrbit #Vikram1

Hardware across the vehicle continues to advance through test. 📍 Long Beach, CA The first stage downcomer completed its full acceptance test campaign. This flight-critical component, which routes liquid oxygen from the tank to the engines, is now cleared for integration. 📍 NASA Stennis, MS Stage 2 is back in the hangar after completing cryoproof and COPV proof testing. Post-test inspections are underway ahead of Aeon V installation. A2 is being prepped for hot fire, with LOX farm flushes and heat exchanger activations. On the R stand, acceptance testing of flight 2 Aeon R engines is underway.

From factory floor to launch site, the Terran R program is gaining serious momentum. Here’s the latest from May across design, build, test, and launch: 🖌️ Design: 17+ component-level Critical Design Reviews completed—rapidly releasing simpler parts like trays and manifolds ahead of structural assembly. ⚒️ Build: The LOX dome was successfully loaded onto the CFSW for its second weld, and the stage 2 transfer tube is now being welded—key steps toward completing the second stage tank. 🔥 Test: Aeon R engine qualification officially kicked off Stennis Space Center with 11+ hot fires in the books in May. 🚀Launch: Cape Canaveral’s LC-16 saw construction milestones—like the completion of the east flume wall in the diverter pit. Plus, we welcomed Robin Petitprez as SVP of Manufacturing & Supply Chain, strengthening our ability to industrialize Terran R at scale.

New milestone achieved! The #Airbus U850 #SIRTAP has successfully completed its first taxi at the Ejército del Aire y del Espacio Getafe Air Base runway, right next to our facilities. During this taxi test, the aircraft is fully controlled from the ground control station. The test verifies the correct integration and performance of the braking system, steering function, navigation sensors, and commands from the control station itself. Why is this key? It confirms the seamless interaction between hardware, software, and vehicle dynamics. It also validates the aircraft's ability to maneuver safely on the ground before progressing to high-speed taxi trials and the subsequent flight test campaign. We are one step closer to the first flight! Stay tuned.

Literally shaking! Behind the scenes of a special test 🚀 Earlier this year, Redshift, our third stage, completed a full vibration test campaign in flight configuration! Unlike isolated component checks, this was the real deal: all systems integrated and tested under simulated launch conditions. Because launch is no gentle ride. Everything must endure intense vibrations and still perform flawlessly. The result? Electronic connections remained strong, the systems (including antennas, telemetry, flight computer, navigation systems) stayed up and running, and we obtained valuable data to further refine and improve. Enjoy this glimpse of Team Redshift and their work behind the scenes, turning challenges into progress, one test at a time!

"The logistical and storage facilities damaged during the attacks require restoration, including with the help of the state." Vladimir Putin spoke today at the Council for Strategic Development and National Projects. Here are the main points from the first half of the President's speech, as reported by RIA Novosti: ✔️ There are no critical consequences from the terrorist attacks on Russia's infrastructure, there have been none, and there cannot be any, but they do cause damage. ✔️ The logistical and storage facilities damaged during the attacks require restoration, including with the help of the state. ✔️ The economic dynamics in Russia are generally modest, but positive. ✔️ Each minister and vice-prime minister must cooperate with the regions, as some areas are lagging behind. ✔️ He asked the government to identify a list of regions whose financial situation needs to be balanced. ✔️ He demanded that the government ensure the balance and stability of the entire Russian budget system. ✔️ The deadline for repaying budget loans by the regions has been extended beyond 2030, which will save the regions approximately 100 billion rubles. ✔️ He urged government officials to actively participate in the "Personnel for the Economy of the Future" program: this is not a trivial matter, it has meaning. ✔️ He called on all regions to quickly launch the electronic assessment service for social institutions, so that people can do this from their mobile devices.

We are back at it with forward module testing, gearing up for New Glenn’s second flight. Part of this testing campaign is to activate the hydrogen peroxide system that fuels our Reaction Control System, or RCS. The GS1 RCS provides 20,000 lbf thrust in any direction, allowing the first stage to reorient itself in space before re-entry and to precisely target Jacklyn in high winds during landing. To give you an idea, a single F-18 Super Hornet F414 engine provides a similar amount of thrust at 22,000 lbf, so you can see how powerful this system is. The RCS performed nominally during our NG-1 flight and successfully reoriented GS1 to within 0.5 deg of our target attitude during exo-atmospheric flight.
