Otta's take

Theo Margolius headshot

Theo Margolius

COO of Otta

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 utilizing 3D printing, Relativity has simplified its supply chain, building rockets in less than 60 days that require 100x fewer parts.

The company has completed its flagship Terran 1 rocket and has begun its initial round of test flights. 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 inflicted on the rocket, Max-Q. The company is set to test the Terran 1 rocket again, before moving on to its Terran R rocket. While the company faces competition against SpaceX, Relativity Space’s cheaper and accelerated building process is well set to be a fierce competitor.
