After an aborted launch try on Wednesday, Relativity House is now prepared for a do-over. The three-hour launch window for the 3D-printed Terran 1 rocket opened at 1:00 p.m. ET on Saturday, and you may catch the motion reside proper right here.
The 2-stage rocket is making an attempt to blast off from Launch Complicated 16 in Cape Canaveral, Florida, throughout a three-hour window that started March 11 at 1:00 p.m. ET and closes at 4:00 p.m. ET. The corporate’s reside broadcast of the launch is beneath.
Editor’s observe: At roughly 1:29 PM ET, or at T-20, the Terran 1 rocket went into a brief maintain because of upper-level wind violations. We’ll replace this story when the countdown resumes.
Relativity House has playfully dubbed this the “Good Luck, Have Enjoyable” mission, and for good motive. No non-public firm has ever launched its personal rocket to orbit on the primary try, not to mention a rocket that includes as many cutting-edge options as this one. The corporate received’t be together with a buyer payload given the dangers.
Terran 1, along with being 85% 3D-printed by mass, is fueled by methane. So far, no launch supplier, non-public or public, has managed to efficiently ship a methane-fueled rocket to orbit. The chances appear stacked in opposition to Relativity House to succeed on its first attempt, however we’re rooting for the California startup, based eight years in the past by Tim Ellis and Jordan Noone—two former engineers with Blue Origin.
Relativity House had hoped to launch the 9.3-metric-ton Terran 1 on Wednesday however was pressured to clean the launch try “because of exceeding launch commit standards limits for propellant thermal circumstances on stage 2,” as the corporate defined on Twitter. In different phrases, the scrub was known as as a result of floor groups couldn’t get the methane gasoline within the rocket’s higher stage to achieve the required temperature for launch.

9 3D-printed Aeon engines energy the rocket’s first stage, whereas a single 3D-printed Aeon Vac engine powers the second. Relativity leverages a proprietary additive manufacturing course of to construct the engines. Each varieties of Aeons use a mixture of liquid oxygen and liquid pure gasoline, “which aren’t solely the very best for rocket propulsion, but in addition for reusability, and the best to finally transition to methane on Mars,” in accordance to Relativity.
Methane, the first element of pure gasoline, has been deemed the rocket propellant of the long run. An orbital launch try was made by China’s Zhuque-2 in December 2022, however the methane-fueled rocket failed to achieve its vacation spot. SpaceX’s Starship higher stage rocket likewise runs on methane gasoline, however all assessments executed up to now have concerned suborbital flights. All eyes are actually on Relativity House to make historical past.
Reaching orbit can be an excellent end result, however merely having the rocket go away the launch pad can be a passable end result. One other key milestone for the GLHF mission can be for the rocket to outlive Max-Q—the second when rockets endure the best aerodynamic stress. For Terran 1, this second will arrive one minute and 20 seconds into the mission. Different key moments will embrace stage separation, ignition of the second stage engine, and orbital insertion.
We’re excited to see Terran 1 take flight, and to the group at Relativity House, we solely have this to say: Good luck, and have enjoyable.
