Relativity House’s Terran 1 rocket, the world’s first 3D-printed launcher, will fly for the primary time right this moment (March 8), and you may watch the motion reside.
The 110-foot-tall (33 meters) Terran 1 is scheduled to raise off from Cape Canaveral House Drive Station in Florida right this moment throughout a three-hour window that opens at 1 p.m. EST (1800 GMT).
You’ll be able to watch the orbital take a look at flight — referred to as “Good Luck, Have Enjoyable,” or GLHF for brief — right here at House.com, courtesy of Relativity House, or immediately through the corporate (opens in new tab).

GLHF is a landmark mission for Relativity House, and for spaceflight know-how on the whole: The 2-stage Terran 1 is the primary rocket ever constructed primarily through 3D printing. This primary Terran 1 is about 85% 3D-printed by mass, although the corporate goals to spice up that to 95% on future automobiles.
One key purpose of right this moment’s take a look at flight, subsequently, is to indicate that the automobile is powerful sufficient to deal with the trials of launch.
“As for flight success, safely clearing the pad, getting out over the ocean and passing Max-Q can be a giant inflection level for right this moment’s launch,” Relativity House representatives informed House.com through electronic mail. “Max-Q is the purpose the place the structural hundreds on the automobile are the very best, making it one of the crucial difficult phases of flight, so passing this milestone would successfully reveal that 3D-printed rockets are structurally viable, along with already efficiently finishing acceptance testing on the bottom at our manufacturing unit at these max stresses.”
Getting all the way in which to low Earth orbit (LEO), they added, “can be a complete residence run.”
The Terran 1 will not deploy something even when it does make it to LEO; the rocket is not carrying a viable payload, only a commemorative 3D-printed metallic ring that weighs about 3.3 kilos (1.5 kilograms), in response to EverydayAstronaut.com (opens in new tab).
California-based Relativity House was based in 2015 by Tim Ellis and Jordan Noone, each of whom had labored at Blue Origin. Noone was employed by SpaceX as properly.
The Terran 1 makes use of methane as a propellant and liquid oxygen as an oxidizer. Will probably be the primary U.S.-developed “methalox” rocket to aim an orbital launch, and it might be the primary such automobile worldwide to achieve orbit. (Beijing-based firm Landspace’s Zhuque-2, a methalox rocket, launched in December 2022 however failed to achieve orbit.)
The expendable Terran 1, which is powered by 9 of Relativity House’s Aeon engines in its first stage and one in its higher stage, can ship as much as 2,756 kilos (1,250 kg) to LEO, in response to Relativity House (opens in new tab). However the firm is growing one thing a lot bigger and extra highly effective.
Certainly, the Terran 1 is a developmental step towards the Terran R, a reusable rocket designed to hold as much as 44,100 lbs (20,000 kg) to LEO. The 216-foot-tall (66 m) Terran R may fly for the primary time as early as subsequent 12 months, firm representatives have mentioned.
“Terran 1 serves as a pathfinder and improvement platform on our path to Terran R manufacturing,” Relativity House representatives mentioned the e-mail to House.com. “Terran 1 has served us exceedingly properly on this capability main as much as our first launch, and we anticipate extra key studying will come from launch day as properly.”
