A 2.5-second rocket flight that heralded decades of discovery in space! Today marks 100 years since the first successful test of a liquid-fueled rocket. Robert H. Goddard's achievement would have appeared unimpressive by most measures: His rocket flew just 41 feet in the air, landing in a nearby cabbage patch. Liquid-propelled rocketry has been the backbone of spaceflight ever since. 📷 by Esther Goddard on March 16, 1926 (Clark University Archive)

We’ve opened a new 20,000 sq. ft. manufacturing facility outside Boulder, Colorado. The site expands Guidance, Navigation, and Control (GNC) development for Mira and Helios. And, it adds multi-axis CNC and precision mill-turn machining for propulsion hardware, including valves used during orbital burns. And we’re growing our team in the region.

@lrocket @SpaceAbhi Gwynne and I didn’t tell the company, as it would have been demoralizing


SpaceX is one of the most dominant companies on the planet and their performance gap just keeps getting bigger. In 2025, SpaceX launched more mass to orbit than every other provider on Earth combined. MUCH MORE: every payload from China, Russia, Europe, and all American launchers wasn’t even a fifth of what SpaceX put into orbit. They’re the only company producing rockets at an industrial scale. The practices that made SpaceX dominant aren’t unique to rockets. They’re a blueprint for building anything hard. This episode — and the essay it is based on — explores How SpaceX Works:

President Trump gave the world the Artemis Program, and NASA and our partners have the plan to deliver. We will standardize architecture where possible, add missions and accelerate flight rate, execute in an evolutionary way, and safely return American astronauts to the Moon, this time to stay. This is the NASA that once changed the world. This is the NASA that will do it again.


Today we announced our $150M Series B led by @IndexVentures with major participation from @Redpoint and returning investors including @ThriveCapital, @Felicis, and @AbstractVC. Across aerospace, energy, and manufacturing, engineering teams are pushing what’s possible. The software behind many of these systems hasn’t kept up. Revel gives engineering teams the infrastructure to test and control complex hardware systems with speed and confidence. In just over a year, we’ve built a world-class team, converted every pilot into a customer, and are now expanding the platform across new industries. If you believe great hardware deserves great software, we’re hiring across the board.






After overnight data showed an interruption in helium flow in the SLS interim cryogenic propulsion stage, teams are troubleshooting and preparing for a likely rollback of Artemis II to the VAB at @NASAKennedy. This will almost assuredly impact the March launch window. @NASA will continue to provide updates as they become available.


Haven Demo has successfully completed its initial perigee-lowering maneuver to demonstrate the spacecraft's ability to perform a controlled deorbit. The spacecraft engaged its orbit-maneuvering thrusters for approximately 14 minutes, lowering perigee by ~170km.
