Recently, Relativity Space announced the details of Terran R, a new type of two-stage rocket that is the key to this Southern California startup’s bold extraterrestrial goals, including helping humans gain a foothold on Mars. If everything goes according to plan, a fully reusable 3D printed rocket will launch the satellite into orbit in three years.

“Terran R is at the forefront of rocket innovation and design,” Relativity Space senior vice president of engineering and manufacturing Zach Dunn said in a statement. “Fully reusable and fully 3D printed, Terran R will be ideally suited to meet the changing needs of customers in the large satellite constellation industry, and also represents a major leap forward in our mission to build a human industrial base outside the earth.”
Terran R will be a big improvement in the power and performance of the two-level Terran 1. Terran 1 is a consumable rocket. Relativity Space is expected to start flying later this year. Company representatives said that nine different customers have signed contracts to place payloads on Terran 1.

Terran 1 is 115 feet (35 meters) high, 7.5 feet (2.3 m) wide, and has a maximum load capacity of 2,756 pounds. (1,250 kg) to Low Earth Orbit (LEO), according to its specification page. The first stage of the vehicle is powered by nine Relativity Space Aeon 1 engines, while the upper stage is equipped with a vacuum-optimized Aeon.
The engine that burns liquid oxygen and methane is 3D printed, just like the rest of the rocket. Company representatives stated that this manufacturing strategy allows Relativity Space to manufacture rockets with 100 times fewer parts than competitors and produce a complete vehicle in less than 60 days.
Terran R is expected to be launched for the first time in 2024. Like Terran 1, it will set off from a launch pad at the Cape Canaveral Space Force Station on the Atlantic coast of Florida.
