I've spent more than a decade of my life working to today. It was worth it. The next ten years is about scaling up so the rest of us can benefit from supersonic travel.

Congrats to Boom Supersonic and Blake Scholl 🛫 going sonic today! Inspiring!!!

That feeling you get when you look out the window and realize you’re almost home! T-4 days until we land in the Moon. Blue Ghost will reach her final destination no earlier than 2:34 am CST on March 2. We’ll start the joint livestream with NASA at 1:20 am CST, approximately 75

Incredible view of the moon, well done Firefly Aerospace

General Matter is enriching uranium for the US. We will revive nuclear fuel production in America. We chose to do this not because it’s easy, and not because it’s hard, but because it needs doing. Nothing gets made if fuel isn’t made. America’s ambitions, from manufacturing to

Excited for the Airship team - airship-industries.com - to be recognized as one of the most exciting hard tech startups by the Black Flag 100 - blackflag.vc/100 Check out some of the incredible projects on the list!

Beautiful animated breeder reactor film here from the late 1970s, with a to-the-point description of breeders and then a detailed depiction of the major systems in Superphénix, the largest sodium-cooled reactor ever built. This is also from the Ron Knief collection. Thanks to

I'm so obsessed with planes launching from and recovering to airships I had to re-edit some of this footage and convert to HD. The folks we inherited this great nation from were flat out nuts. Thank God. 🤘😎

Today's legalization was enabled by the 2018 Lee-Gardener amendment... paving the way for development and testing that led to XB-1 and boomless cruise. It takes vision and leadership to make fast things. And it started with yours Mike Lee and Cory Gardner! Grateful!

Does it take more capital to build a deep tech startup? No, not necessarily. If you add median cash raised for Seed through Series C based on data from H1 2025, you get: Software: $75.3 million raised Deep tech: $81.9 million raised Time to build in atoms?

Organizational design is core to hardtech product design.

Now we have video showing what two metric tons of West Virginia graphite looks like as it's extruded by our friends at Amsted Graphite Materials. This is the first reactor order of American-made, nuclear-grade graphite in over a decade, and it's coming to Radiant!

Big, big news from California VCs.

Incredible size comparison between a C-17 Globemaster III and a C-5 Galaxy.
