NASA Administrator Jared Isaacman

I love my job. Honored to serve 🇺🇸

LIVE: After Wednesday's launch attempt was postponed due to inclement weather, tune in for today's live coverage of our next cargo resupply mission to the @Space_Station. Liftoff is scheduled for 6:05pm ET (2205 UTC). twitter.com/i/broadcasts/1…

@RepAbeHamadeh 🇺🇸

WOW — this is huge. Congressman Hamadeh’s Maverick Act has skyrocketed to become the #2 most-viewed bill in America. The bill to save three legendary F-14 Tomcats, the same iconic jets from 𝘛𝘰𝘱 𝘎𝘶𝘯, is striking a major chord with the American people. Let’s get it through the House and to the President’s desk.

@TheSilverHorsey @NASAStennis I am a pro

@NASAAdmin @NASAStennis Fellow Jared, how did you manage to go to a crawfish boil and not get that white shirt dirty? Is that some sort of NASA-engineered shirt? It's astounding.

Joined the talented people of @NASAStennis for their annual crawfish boil. This tradition brings together the people, families, and partners behind some of the hardest engineering challenges in the world. Grateful to everyone helping make our return to the Moon, Mars, and beyond possible.

This week, we hosted @NASAAdmin Jared Isaacman at Skunk Works®, where decades of breakthrough innovation have taken shape and the X-59 was built. It was a privilege to showcase the talent, ingenuity and momentum driving the future.

From planetary science to space security, @Livermore_Lab has a long history of advancing space science and technology. Recently, LLNL was excited to welcome @NASAAdmin Jared Isaacman for a closer look at the research driving discovery, innovation and mission impact.

@Livermore_Lab Extremely impressive visit to @Livermore_Lab. Grateful to Administrator @NNSAWilliams. We are looking forward to the continued collaboration.

Did you think the Ignition event was a signal America was retreating? A more achievable path back to the Moon, building a Moon Base in parallel, eventually transitioning to multiple affordable commercial pathways to the lunar surface, investing in the next giant-leap capabilities and finally getting underway on nuclear power in space, stimulating an orbital economy, and launching more missions of science and discovery. The event was not just PowerPoint and words. We are rebuilding core competencies, bringing talent back into NASA, and regaining muscle memory. We intentionally incorporated numerous RFIs and made a commitment that NASA SME's will embed across the supply chain and actively drive the outcomes the world is waiting to see. And while stakeholders may not have been aligned in the past on the true needle-moving objectives, if people are paying close attention, it sure looks like we are aligned now.

FWIW @NASAAdmin Skylab was possible because we turned our back on the Moon after a few missions with rocket stuff leftover. America needs a space strategy that expands - not retreats - and continues across Administrations and Congresses.

America's first space station—and the last Saturn V—take flight! 🚀 Launched OTD in 1973, the main structure of Skylab—its Orbital Workshop—was built from a converted Saturn S-IVB rocket stage roughly 22.8 feet (6.7 m) in diameter.

Less than six months after Apollo 17 returned from the Moon, we launched the Skylab space station on a Saturn V. What a time. It may be half a century later, but we have accomplished grand, near-impossible goals before, and we will assuredly achieve them again. Root for the home team and start believing again 🇺🇸

@USAmbCanada Our pleasure Mr. Ambassador 🇺🇸

A special thanks to @NASAAdmin Jared Isaacman for his personal commitment to making this visit happen. The Artemis II crew is leading humanity’s return to the moon— American courage lighting the way forward.

@SenateCommerce @SenTedCruz @SenatorCantwell @NASAArtemis @NASA 🇺🇸

🚨ICYMI: This week the Committee, led by Chairman @SenTedCruz and Ranking Member @SenatorCantwell, hosted the @NASAArtemis II crew members to honor their historic mission into deep space. American space superiority is here to stay. 🚀🇺🇸 @NASA @NASAAdmin

From the Bilateral Meeting in Beijing: President Trump had a good meeting with President Xi of China.

I actually did post on X regarding the report a month or so ago. I really value the IG work at NASA. It is a sobering story, and as I wrote previously, it should serve as a cautionary tale about contracting methods, especially leaning into an 'as-a-service' model when NASA is the only customer and before a market has matured. The report was also largely written before the changes we implemented a few months ago, when I posted publicly about the NASA resources we are embedding across the supply chain to take an active role, clear blockers and drive outcomes. That statement applies to the entirety of Artemis acceleration initiative, the Moon Base buildout, and other key programs... We won't sit on our hands...and the suits will be tested in LEO in 2027.

@NASAAdmin @dpoddolphinpro @NASA Care to comment on the fact that an NASA IG report recently warned that the timeline for the AxEMU suit demonstration occuring during the 2027 Artemis III LEO flight rather than on the Moon is "ambitious given historical development averages"? Thanks.

.@NASA Confirms More Artemis III Plans - Spacer instead of upper stage (saves the ICPS for Artemis IV) - Low Earth Orbit officially confirmed - Artemis III will last longer than Artemis II to further evaluate Orion's life support systems - Test an upgraded heat shield Design and fabrication activities for the spacer are "progressing rapidly" at @NASA_Marshall. Material for the barrel section and the upper and lower rings is currently being machined. Expect more plans to be refined over the coming weeks.

Lori - always appreciate the interest and commentary! We never officially moved the timing of Artemis III to 'late' 2027. A reporter wrote that after misinterpreting my quick response to a question during a budget hearing. In the same hearing, I also said we were gaining increased confidence in interoperability tests with both landers in 2027. I am quite sure at least one will incorporate an ECLSS demonstration. As for 2028, we have always said we would protect for up to two landing attempts, if required. That story has not changed, and the South Pole was always the landing target. The only goalposts that have moved have been in the direction of achievability--standardizing the architecture, adding missions, focusing resources, and rebuilding in-house competencies. We have tried to communicate to the greatest extent possible in this regard, while respecting the proprietary information of our commercial partners. I will say, I am very proud of the NASA team and the new pace we are moving at. The public will learn in the weeks ahead which astronauts will undertake Artemis III, and I would not be surprised if you see some early wet dress testing at 39B before the end of this year. Now, if your point is that the schedule is ambitious, I agree. And NASA’s recent track record on schedule has not been great, but when it comes to landing astronauts on the Moon, historically, our batting average was pretty good. I suspect it will be again.

The goalposts are already shifting. Artemis III slips to late '27 (still unlikely) & landers may not have life-support. Artemis IV considering options to South Pole & talk of 2 landings in '28 has ended. Hot take - Summit proposes cooperation with China on lunar development!

The beginning of history. 🇺🇸🇨🇳 📸 President Trump arrives in Beijing, China to kick off a landmark state visit.

Planning is underway for our Artemis III mission, which will test the capabilities of NASA's Orion spacecraft and one or both commercial landers from @BlueOrigin and @SpaceX as they meet and dock in Earth's orbit. Details: go.nasa.gov/4nvfifB

A beacon of freedom, hope, & the American spirit. 🇺🇸
