Astra

Another hot fire as our test cadence ramps (sound on this time).

Rocket 4.0 flight feature complete engine, running a full characterization sweep across its operating range.

Transporter-17 just delivered more @Astra satellite engines to orbit. Grateful to support our customers and partners on this @SpaceX mission!

250 years ago, a bold idea took flight. Today, we carry it upward. @Astra is proud to build and provide American space products and services — responsive, sovereign, and made to serve the nation that made it possible, and its allies. Happy Fourth of July from Astra.

EXCLUSIVE INTERVIEW: @Astra has built a mobile launch system designed to send rockets into space within 48 hours, with the rocket and launch equipment transported in standard 40-foot shipping containers. @Kemp, CEO of Astra Space, sees sovereign access to space as critical to national security. With launch capacity constrained and traditional spaceports tied to fixed infrastructure, Astra wants to give the United States and its allies the ability to rapidly deploy launch capability around the world. The vision is a distributed network of mobile spaceports that strengthens resilience and deterrence and could be established almost anywhere, even in a Walmart parking lot.

Founder & CEO Chris @Kemp joined CNBC's @SquawkStreet this morning to talk about where space is going — driving the cost of launch down, the growing role of communications systems in space, and why sovereign launch capability matters more than ever: cnbc.com/video/2026/06/…

"It's always sunny in space," says Former NASA CTO & Astra CEO @Kemp as $SPCX's IPO puts space infrastructure & solar energy in focus: cnbc.com/video/2026/06/…

Nearly a decade ago, Adam and I started Astra with a simple idea: launch shouldn’t be limited to a handful of places on Earth. Today, our next-generation rocket is sitting in the English countryside after crossing the Atlantic in standard shipping containers. The future of launch is everywhere.

Astra’s next-generation rocket just crossed the Atlantic. Rocket 4.0 arrived in the UK the same way it’s designed to launch: in standard shipping containers. Mobile. Containerized. Orbital. The future of launch is everywhere.

Golden Dome, mobile launch, and what's next for Rocket 4.0: payloadspace.com/astra-targets-… — @jacqfeldscher @payloadspace

We're heading to @SpaceFoundation's 41st Space Symposium and we'd love to connect. If you're in Colorado Springs April 13th–16th and want to talk launch services, satellite engines, or what's next for Astra — reach out at hello@astra.com. See you there! #spacesymposium #spacetech

Congratulations to the Artemis II crew, and to all the teams at @NASA and beyond who made this possible. An inspiring moment for everyone who cares about space.

Want to build the future of space? From the factory floor to the launch pad to orbit — we're hiring. Come get your hands on hardware that matters: astra.com/careers #adastra

Close proximity testing with two xenon thrusters in one of our large chambers.

@RahulRaghav_10 The new combustion chamber is designed to increase both the thrust and Isp of the engine while allowing us to manufacture chambers more quickly and with a much lower scrap rate.

@Astra curious what's the goal for the new combustion chamber design

This week on the test stand: the Astra team continues pushing the run box limits of our Rocket 4.0 first stage engine combustion chamber.
