Our take

Relativity Space has set out to build humanity’s multiplanetary future with its innovative 3D printed rockets. The company is at the forefront of software-defined manufacturing, combining 3D printing, AI, and autonomous robotics to create the “factory of the future.” By utilising 3D printing, Relativity has simplified its supply chain, building rockets in less than 60 days that require 100x fewer parts.

The company completed its flagship Terran 1 rocket and initial round of test flights in 2023. While the first launches technically failed, as the rocket failed to reach orbit, the attempt is still classified as a resounding success, as the rocket managed the highest stress state - Max-Q. The company is currently building its follow-up Terran R rocket, which is set for a debut launch in late 2026. While the company faces competition from SpaceX, Relativity Space’s cheaper and accelerated building process is well set to be a fierce competitor.
