Golden Dome, mobile launch, and what's next for Rocket 4.0: https://t.co/c7t9BTRZS6 — @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 [email protected]. 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.

For the first time in over 50 years, humans are Moonbound.

At 6:35 p.m. EDT (2235 UTC) NASA’s Space Launch System rocket and the Orion spacecraft lifted off from the agency’s Kennedy Space Center in Florida, sending four astronauts on a planned test flight around the Moon and back. https://t.co/0Q9ZB4IWVI

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

[Astra @Astra]

@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.

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.

[John Kraus @johnkrausphotos]

I’m humbled and energized to bring my passion for photography and storytelling to NASA and work under @NASAAdmin Jared Isaacman as Special Communications Assistant to the Administrator.

With my focus now fully on working alongside the best and brightest at NASA, my independent media coverage and for-hire work comes to an end. Thank you all for following along over the years! Be sure to follow NASA’s channels to see great content from across the agency.

I have deep respect for NASA’s communicators and creatives, individuals whose work I’ve followed and admired for a long time. I’m profoundly grateful for the opportunity to work with them to help continue sharing NASA’s story with the widest audience possible and inspiring the next generation to look up to the stars. Under Administrator Isaacman’s leadership, we will do just that.

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.

[Chris Kemp @Kemp]

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

[Astra @Astra]

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

[Astra @Astra]

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