When might we expect a static fire of the first stage?

Very exciting!

the way they stack interstage barrels like lego rings for something this tall is oddly satisfying

A strong integration milestone. The next proof is whether production cadence and test results keep pace with the hardware stack.

Terran R build is continuing to ramp up this fall. From avionic builds to expanding of our machine shop capabilities and more. 🔥In prop, teams completed assembly of the second Aeon R engine for first flight and reduced average cycle times across key engine components by 50%. 💻The avionics team is building the flight hub box, which will serve as Terran R’s central node for routing data and distributing power to critical systems. 🚀Welding of the first stage tank is progressing with 3 circumferential friction stir welds now complete.

Early flight suits were both bazaar and badass. In 1938, Canadian inventor Carl Rich created a stratosphere flight suit for piloting up to 30k ft, with oxygen tank & radio "telephone" on leg. Tested to 38k ft (-80°F). Built two; one for testing, one to wear around the house.👀

A ton of historic firsts last week. Our Relativity Space team proved more in this first launch than most companies (and even countries) ever have in their maiden attempt: ✅ first methane fueled rocket in the West to reach space, well over the 100km Karman Line (only other is China) ✅ first nearly entirely 3D printed rocket to fly and prove 3D printing is viable by passing Max-Q, the max stress on the rocket ✅ first methane orbital-class rocket to successfully complete stage 1 flight, main engine cutoff, and second stage separation in the West (only other is China) ✅ first-ever second stage ignition attempt during the vacuum of flight for a methane fueled orbital rocket in the West, collected first-ever flight data ✅ continuing data reviews, and will bring learnings to our future rocket including Terran R ✅ one really ecstatic launch viewing experience - here, as close as one can get to the launch pad. INTENSE 12 of 10, the reaction makes perfect sense when being there, surreal 🤯
