    FULL DURATION 20 second stage test complete! Reviewing data and if all looks good, on to full flight duration test before LAUNCH. We are the first company to ever do this on launch mount at Cape Canaveral, and on track to be the first oxygen/methane rocket launched to orbit 👾🇺🇸

    A ton of historic firsts last week. Our @relativityspace 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

    This may look like all our other engine tests but it’s not… first Aeon R full-scale hot fire test! 🔥 goal by the team, this was 35% power level of the 268,000 lb max thrust. These brand new 3D printed engines will power Terran R. Massive push to get this done so quickly 🤯🤯🤯

    7 years ago, I remember at @ycombinator our mentor @sama told us we were absolutely crazy for trying to simultaneously invent a brand new manufacturing technology and an orbital rocket, which is already super hard. Now we are on the launch pad almost ready to go with the world’s

    You’ve asked, “Wen Launch?” and to that, we say...👇 Catch us live at Launch Complex 16 in Cape Canaveral, FL on March 8, 2023 to watch the world’s first 3D printed rocket fly. 🚀 #GLHF bit.ly/3xIWv7C
