NASA Administrator Jared Isaacman

I love my job. Honored to serve 🇺🇸

One. More. Day. #UFCWhiteHouse #America250

AMERICA AF. 🦅🇺🇸

@WhiteHouse @Interior @Freedom250 The Capitol looks magnificent ahead of America’s 250th birthday 🇺🇸

Not just celebrating history, making it. 🇺🇸

I had the opportunity to visit @NASALangley today and spent time with the extraordinary workforce helping shape the future of American aerospace and space exploration. Their work helps support Artemis, future lunar operations, advanced flight system materials and hypersonics, and nuclear technologies in space. America's leadership in space depends on people willing to solve hard problems, and Langley is full of them.

@RapidResponse47 🇺🇸

While today's IPO is good for SpaceX (and deservedly so). It is broadening the aperture of opportunity for all US commercial space companies. That's good for the nation, and it's good for all of us who work to see America retain the leadership of space technology and innovation for generations to come. 🚀🇺🇸

@HouseGOP 🇺🇸🇺🇸

GOD BLESS THE USA! 🇺🇸

Blue Angels & Thunderbirds practice flight over the White House!

Great meeting with some of NOAA’s Hurricane Hunter pilots and learning firsthand about the demanding missions they fly in support of hurricane forecasting. Thanks to the entire Hurricane Hunter team for the work they do every hurricane season.

We are returning to the Moon, to build something extraordinary and continue mankinds greatest adventure to the stars. @NASAMoonBase will serve as an outpost for science, technology demonstrations, and the development of capabilities that will shape the future of exploration and prepare us for Mars.

We are sending the best NASA astronauts based on crew rotation, background, and expertise on Artemis III. The same way we sent our best on Artemis II. The same way we send our best astronauts to the International Space Station, where the recent Crew-10 through Crew-13 assignments ALL include female commanders and crews that are no less than 50% female. Not because it was a requirement, but because they are the best astronauts for the job. Celebrate the Artemis III crew the same way we will celebrate all crews who follow that will walk again on the Moon.

@NASAAdmin You still haven't answered the question about why there are no women on this upcoming mission

Ambitious is what we do at NASA. Artemis III will be unlike anything we’ve ever undertaken. A multi-launch campaign bringing together the most powerful rockets in the world to test rendezvous, docking, and interoperability across multiple systems close to Earth before we return astronauts to the lunar surface. This is how we get into the rhythm of the missions that follow. You give NASA and our industry partners a year, we’ll get the job done.

🇺🇸 America turns 250 and we're celebrating accordingly. 56 states and territories. 150+ exhibits. Daily programming. Military flyovers. Live performances. American innovation, industry, culture, and tradition on display in the heart of the nation's capital. June 25–July 10, 2026. The biggest birthday party in American history.

@SpaceflightNow Congrats to our JAXA partners on a nice-looking launch.

Liftoff of the debut flight for JAXA’s H3-30 rocket at 9:53:59 a.m. JST / 0053:59 UTC on June 12 (8:53:59 p.m. EDT on June 11) from the Tanegashima Space Center!

@dougdonnell @NASAArtemis We similarly warned Steve Buscemi during his planetary defense mission to space and this is what happened.

@NASAArtemis @NASAAdmin Fun-haters…

Big week for Artemis III 🚀 Just before NASA introduced the Artemis III crew, the SLS solid rocket booster segments arrived in Florida after a six-day rail journey from Utah. Later this year, teams will begin stacking the boosters that create 75% of the thrust needed at launch.

@RapidResponse47 Congrats on the nomination!

Apollo taught us what was possible. Artemis is showing us what comes next. We no longer have to put everything on a single rocket. Artemis III will bring together multiple launch providers and reusable systems so we can learn, improve, and build the capabilities needed for a sustained human presence beyond Earth. This time, we are building the capabilities to stay.

The future of exploration will be built through thriving spaceports, reusable rockets, orbital assembly, and technologies we once only imagined. Just as railroads and highways transformed our economy, tomorrow’s orbital and lunar economy will help power what comes next. Very exciting times ahead.
