Relativity aims to build a rocket that is 95 percent 3D-printed.
Terran 1 is propelled by engines using liquid oxygen and liquid natural gas—the “propellant of the future,” capable of eventually fueling travel to Mars, says Relativity.
SpaceX’s Starship and Vulcan rockets being developed by United Launch Alliance use the same fuel.
Relativity is also building a larger rocket, the Terran R, capable of putting a payload of 44,000 pounds (20,000 kg) into low Earth orbit.
The first launch of the Terran R, which is designed to be fully reusable, is scheduled for next year.
