Happy Fourth of July. 🇺🇸 As we celebrate the 250th anniversary of our nation's founding, Vast is dedicated to building the next space station for America and the world.

.@vast is on a mission to replace the International Space Station, and we went to Long Beach, Calif. to check out its operations. The company is racing to get to space in 2027 with Haven-1, which will have room for four people. We saw its manufacturing operations, food labs, the whole Haven-1 design. It was an awesome trip! Full episode in the replies and on the Core Memory channel.

Vast welcomes Steve Isakowitz, former president and CEO of The Aerospace Corporation and NASA executive, to our team of advisors. vastspace.com/updates/former…

Vast's 10 kW Hall thruster firing in a vacuum chamber. Designed for Vast satellites and future space stations, our in-house electric propulsion system builds on @NASAJPL's H10 heritage and has demonstrated >3,000 s specific impulse and 1–10 kW operation. vastspace.com/satellites

Excited to announce we flew our second mission, MicroBrew-2, on @SpaceX's Starfall Demo mission yesterday! This launch carried a payload called the Brewery Archive Space Exposure Demonstrator which held dozens of different strains of brewing yeasts, distiller’s yeasts, and wine yeasts from around the world. (Hint: we miiiight be announcing some insanely cool new products soon...👀) We also included seeds from a bunch of native Texas plants, including Bluebonnets! Next we'll analyze the yeast strains and seeds to see how they adapted to the spaceflight environment. This was the successor to our MicroBrew-1 and OASIS missions that were performed on the International Space Station last year. In MicroBrew-1, an astronaut combined wort and yeast (the same two ingredients using in brewing beer) so we could study alcohol fermentation in microgravity. The OASIS experiment successfully grew the first-ever crops in soil in space. Humanity is still in the early days of orbital manufacturing but we aim to stay at the forefront of it! Huge shoutout to the SpaceX team for the incredible opportunity to fly on a new vehicle. And we have some more exciting announcements coming up related to this mission so stay tuned!

Thank you to @CAgovernor for awarding us a $32.75M California Competes Tax Credit through @CAGoBiz. We’re proud to be headquartered in Long Beach, Calif., and committed to creating hundreds of new jobs locally as we build the future of commercial space systems. gov.ca.gov/2026/06/22/govern…

I bought Shift4 stock, the company I started 27 years ago, that serves predominantly hotels, restaurants, and stadiums, because it was trading at a multi-year low and permissible under my ethics agreement. I sold all SpaceX stock, any indirect equity exposure to it, and any other aerospace-related companies 18 months ago when I was first nominated for the job. A billion-dollar sacrifice I was happy to make to serve my country. I suspect I will be worth much less coming out of public service than going into it-- and that is completely fine!

ESA will implement an astronaut mission to the International Space Station for the Czech Republic with @vast 🇨🇿👨‍🚀 Member of @esa's astronaut reserve @astro_ales is planned to serve as the mission’s pilot and would become the first Czech astronaut to visit the International @Space_Station, alongside ESA astronaut @Thom_astro as commander. The mission is planned for no earlier than 2027. More details: esa.int/Newsroom/Press_Relea… @mpo_tweetuje
