The decision to skip a final static fire suggests Relativity may have reached the F---it, Fly-it mode. Almost all rocket startups reach the point where they've worked so damn hard, and so damn long on the first rocket that they just want the damn thing to fly.
Terran 1 has been on a journey from Long Beach, CA to Stennis, MS to Cape Canaveral, FL. Journey with us. 👇
What is Relativity using for flight termination? Thrust termination? Command Destruct? AFSS? Have they said anything publicly? Just curious.I know their PUG from 20202 says AFSS, but thats not always the case for the first missions

Command-termination and AFTS are the initiation method, and explosive tank unzipping or thrust termination is the mechanism of action. For example, Rocketlab's Electron flight 1 was command-terminated using thrust-termination, Falcon 9 employs AFTS and explosive tank unzipping, Atlas V employs command-termination and explosive tank unzipping, and todays Electron uses AFTS and thrust-termination.

7 moonlit nights until Terran 1—the world’s first, entirely 3D-printed rocket—takes to the skies🌕🚀
Relativity is scheduled for its first launch of Terran 1, called "GLHF" (Good Luck, Have Fun), from Launch Complex 16 in Cape Canaveral, Florida. Our launch window opens at 1300ET on March 8, 2023. This launch of Terran 1 is the first orbital attempt by Relativity and will not include a customer payload. Standing 110 ft. tall and 7.5 ft. wide, Terran 1 is the largest 3D printed object to attempt orbital flight. As a two-stage, expendable rocket, Terran 1 has nine 3D printed Aeon engines on its first stage and one Aeon Vac on its second stage. Like its structure, all Relativity engines are entirely 3D printed, and use liquid oxygen (LOX) and liquid natural gas (LNG), which are not only the best for rocket propulsion, but also for reusability, and the easiest to eventually transition to methane on Mars. Follow along for updates on our lead up to launch: https://twitter.com/relativityspace #GLHF
What’s inside Terran 1’s nose cone? 👀 Check out one of our very first metal 3D prints, that’s catching a ride aboard Terran 1.🚀 Printed by the 1st gen of our Stargate metal 3D printers, this print pays homage to the journey behind Terran 1’s first launch.👇 #GLHF
This 6.5” diameter, 3.3lb aluminum alloy ring captures our humble beginnings on the road to launching the world’s first 3D printed rocket.
Relativity first started out as an idea on a Starbucks receipt, where our founders sketched a plan to eventually build humanity’s industrial base on Mars. Now, we’re on the eve of our first launch. 🚀

Passing Max-Q would be a big inflection point. Why? Because it's the phase of flight where the structural loads on the vehicle are the highest, passing this point in flight proves our hypothesis: 3D printed rockets are structurally viable!
If we make it even further in flight to stage separation, we’ll have achieved a full first stage flight. That's another big accomplishment for the team. From there, we will attempt to light the second stage and get Terran 1 to orbit. ✨
#GLHF is years of hard work come to fruition. We’re proud of our team's dedication and grateful to our customers, investors and partners for sharing our belief that just because it hasn’t been done this way before, doesn’t mean it can’t be! Time to write #newhistory 🚀 bit.ly/3xIWv7C
