Astra

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.

Honored to be included again. Our focus stays the same: doing the work that gets us back to the pad. #adastra

Congrats, @johnkrausphotos! You've captured so many unforgettable Astra moments — we can't wait to watch where your lens goes next with @NASAAdmin.

Congratulations @rookisaacman on your NASA confirmation! An exciting moment for NASA and the future of space exploration.

Xenon thruster firing during pre-flight testing in our 3-chamber vacuum. (Sound on!) In recent weeks, more Astra spacecraft engines have been placed in orbit and are now supporting maneuverability for customer satellites around the globe.

This Veterans Day, we honor all who have served, including the veterans in our own community — family, friends, partners, and teammates.

ICBMs aren’t the only threat. Think millions of drones, forward-deployed in thousands of orbital rockets, launched from hundreds of mobile launchers deployed in dozens of countries. Golden Dome must be global, responsive, mass-produced, and unstoppable. @Astra is building the pipeline. 🚀 #EconSpace @alokjha

30+ second hotfire provides data in thermal steady state, allowing us to further optimize our new first stage engine combustion chamber.

Sound on! Here’s the recent hotfire of Astra’s most powerful Rocket 4 first stage engine.

Astra plans mid-2026 first launch of Rocket 4 spacenews.com/astra-plans-mi…

Heading to World Space Business Week in Paris next week? Drop us a note — we'd love to connect: hello@astra.com #WSBW2025

Hotfire at our test facility in preparation for testing the new combustion chamber for the next-generation Astra first stage engine that will power Rocket 4.

Chris Kemp (@Kemp) took @Astra public in 2021 with a bold vision: low-cost rockets launching daily, bringing sovereign space access to every country on Earth. At its peak, the company was worth over $2B. Within two years, that valuation collapsed by 99%. Valley of Depth EP 011 brings Chris back on the show to go inside one of the most dramatic flameouts and attempted comebacks in the commercial space era. We discuss: – Why Astra’s SPAC-era promises didn’t survive contact with reality – What really went wrong with Rocket 3 and how much of that falls on Kemp – The decision to take the company private and buy it back for pennies on the dollar – How Astra raised $80M, and its attempt to raise another $100M+ – The quiet traction of its satellite propulsion business – Rocket 4, and whether this time is actually different – How Astra is being repositioned as a mobile, defense-aligned launch platform Full episode in comments 👇
