The America's space legacy is continuing...

[Blue Origin @blueorigin]

Across our facilities, the American flag is more than a symbol on the wall; it’s a reminder that what we’re building is part of America’s history and future. We're proud to support American leadership in space, honor 250 years of the American pioneering spirit, and be part of the legacy.

Endurance testing continues! We completed a shock test last week, introducing our MK1 lunar lander to the environment generated when it separates from New Glenn.

21 accelerometers were positioned around the vehicle to characterize the shock response. All components exceeded survivability requirements during the test.

Next up: Full vehicle separation testing.

美国人为什么不快乐？许多美国人都表示他们不再相信美国经济是为他们服务的。少数人正在积累令人叹为观止的巨额财富，与此同时，整整几代普通家庭却在担心自己永远买不起房、养不起孩子，也无法安享退休生活。https://t.co/3YXPnywUyM

Final exams for Soyuz training: passed. I used to dislike exams, but after a few decades I appreciate the useful stress they create. It sharpens focus, exposes gaps, and helps the crew get ready for the real day. It’s called eustress. Looking forward to July 14.

Best news I've heard over last 3 days!

[NASA Administrator Jared Isaacman @NASAAdmin]

I enjoyed being at the CNBC event, but I wanted to clarify. The question was about the timing of the Moon Base and recent lunar rover awards. I was pointing out that those missions are not until 2028, which should be well within what is possible for pad recovery.

Blue Origin leadership has responded incredibly quickly, and NASA will do all we can to help with root cause analysis and accelerate pad recovery timeframes while staying extremely focused on progressing the lander.

America is leading the AI race and our foreign adversaries know it.

The Trump Administration will not allow China to subvert American interests by stealing AI.

[Lunar Outpost @LunarOutpostInc]

Lunar Outpost is proud to support NASA’s Commercial Lunar Payload Services program by delivering mobility that enables exploration and science on the lunar surface.

In March 2025, the Lunar Voyage 1 MAPP rover reached the lunar South Pole as part of NASA’s CLPS‑3 mission, carrying instruments to prospect for and collect lunar resources at future Artemis landing sites.

In 2026, the Lunar Voyage 2 MAPP rover will explore Reiner Gamma on NASA’s CLPS CP‑11, carrying science instruments from @JHUAPL to investigate a lunar swirl and magnetic anomaly.

Slated to support global science and exploration at the lunar South Pole in 2030, the @AusSpaceAgency's Roo-ver rover is part of CLPS CT-4 and is being developed by the ELO₂ Consortium, co‑led by Lunar Outpost Oceania and @epequip.

Together, these missions build real spaceflight heritage, advance long-term surface operations, and inform the technologies and operations behind the Eagle Lunar Terrain Vehicle.

Stay Tuned for flight test 12! But they must complete the static fire of booster.

[Elon Musk @elonmusk]

Starship static fire successful!

[James Tsien @TsienJames]

@SpaceX How about Booster?

[Blue Origin @blueorigin]

Docking? ✅

Our Blue Docking System team successfully completed soft capture system testing at @NASA_Johnson's Six-Degree-Of-Freedom Dynamic Test facility. This test completes a key milestone on our Commercial LEO Destinations (CLD) contract.

The fully vertically integrated system will fly first on our Blue Moon MK2 Lunar Lander, then on Orbital Reef and future vehicles. This marks the first time we have confirmed the performance of our pressurized docking system in flight-like scenarios, meeting International Docking System Standard requirements.
