It’s probably the most anticipated launches of the yr: the inaugural flight of a 3D-printed, methane-fueled rocket. We’ve acquired the dwell webcast for you proper right here, in an experimental house mission you gained’t wish to miss.
Replace: 12:22 p.m. ET: Relativity’s dwell webcast has begun, and with an up to date T-0 anticipated for 1:19 p.m. ET.
Replace: 12:09 p.m. ET: In a tweet revealed at 11:48 a.m. ET, Relativity House stated it’s “working by means of a brand new T-0 time and can share an replace on the beginning of our dwell webcast programming quickly.”
Unique article follows.
California-based Relativity House has named it the “Good Luck, Have Enjoyable” mission, which appears wholly applicable for this modern launch. Ought to the 110-foot-tall (33.5-meter) Terran 1 rocket attain orbit, it would set up two milestones: the primary 3D-printed rocket to achieve orbit and the primary methane-fueled rocket to achieve orbit.
The absolutely expendable two-stage rocket is slated to carry off from Launch Advanced 16 in Cape Canaveral, Florida, on Wednesday, March 8 at 1:00 p.m. ET, with the launch window closing three hours later. Relativity’s dwell broadcast, out there above, will start at 12:00 p.m. ET.

The “Good Luck, Have Enjoyable” mission marks Relativity’s first orbital try, and as an indication mission, Terran 1 gained’t be packing a buyer payload. “Onerous to consider the day is sort of right here to launch Terran 1, our first rocket,” Relativity House CEO Tim Ellis tweeted on Tuesday. “7 years in the past, I cofounded @relativityspace, which looks like a lifetime in the past, however is an extremely brief time-frame within the scheme of issues in aerospace.”
The startup, which secured a launch license from the Federal Aviation Administration on February 21, selected to not carry out a closing static fireplace take a look at on the pad, saying it needed to keep away from any pointless put on and tear on the rocket.
Terran 1 would be the “largest 3D printed object to try an orbital flight,” the corporate claims. The rocket is 85% 3D-printed by mass, which is undeniably spectacular, however Relativity is working towards the objective of constructing it 95% 3D printed. The absolutely assembled rocket, sans gas and payload, weighs roughly 9.3 metric tons, or 20,500 kilos, in accordance to the Relativity press package. To fabricate the rocket, the corporate makes use of a proprietary printing course of that leverages AI and autonomous robotics.
The rocket is supplied with 9 Aeon first stage engines and a single Aeon Vac second stage engine. It must be able to lifting 1.2 metric tons (2,756 kilos) to low Earth orbit, and the corporate says its methalox-propelled Aeon engines have undergone over 2,000 take a look at fires.
The rocket runs on a mix of liquid oxygen and liquid pure gasoline, “which aren’t solely one of the best for rocket propulsion, but additionally for reusability, and the simplest to finally transition to methane on Mars,” Relativity claims. Methane, the first element of pure gasoline, is taken into account the next-generation rocket gas. In December 2022, China’s Zhuque-2 rocket grew to become the primary methane-fueled rocket to try an orbital launch; the rocket took flight however failed to achieve orbit and ship its 14-satellite payload. So if Terran 1 succeeds at present and reaches orbit, it would change into the primary methane-fueled rocket to perform this feat.
That Terran 1 will survive the journey to house isn’t any assure. It’s an experimental rocket constructed from experimental additive manufacturing strategies. A key second of the launch can be Max-Q—the second when the rocket experiences probably the most intense aerodynamic stresses. Ought to the rocket fail and crumble to items, that would very nicely be the second it occurs (at T+ 1:20).
“Passing Max-Q can be a giant inflection level,” Relativity defined in a March 6 tweet, as “passing this level in flight proves our speculation: 3D printed rockets are structurally viable.” Wanting past Max-Q, the corporate stated one other “large accomplishment” can be for Terran 1 to realize first stage separation. The corporate’s language is definitely a bit refreshing, because it’s clearly setting affordable expectations for its first orbital launch try.
Certainly, Relativity House is boldly going the place nobody has gone earlier than. No matter what occurs at present, it’s a milestone launch second, as one more personal launch supplier tries to push the envelope.
