Relativity Space could change the economics of private space launches

NelsonG · January 23, 2020

The private launch market is an area of a lot of focus in the emerging space startup industry, not least because it unlocks the true potential of most of the rest of the market. But so far, we can count on one hand the number of new, private space launch companies that have actually transported payloads to orbit. Out of a number of firms racing to be the next to actually launch, LA-based Relativity Space is a prime contender, with a unique approach that could set it apart from the crowd.

I spoke to CEO Tim Ellis about what makes his company different and about what kind of capabilities it will bring to the launch market once it starts flying, something the company aims to do beginning next year. Fresh off a $140 million funding round in October 2019, Relativity’s model could provide another seismic shift in the economics of doing business in space, and has the potential to be as disruptive to the landscape — if not more so — as SpaceX.

“We built the largest metal 3D printers in the world, which we call a ‘Stargate,’ ” Ellis said. “It’s actually replacing a whole factory full of fixed tooling — and having all of our processes being 3D printing, we really view that as being the future because that lets us automate almost the entire rocket production, and then also reduce part count for much larger launch vehicles so our rocket can carry a 1,250-kg payload to orbit.” Because Relativity Space’s launch vehicle is nearly 10 times larger than those made by Rocket Lab or Orbex, “it’s a totally different payload class.”

That difference is crucial, and represents the paradigm shift that Relativity Space could engender once its products are introduced to the commercial market. The company knows first-hand how its approach fundamentally differs from existing launch providers like Blue Origin and SpaceX — Ellis previously worked as a propulsion engineer at Blue Origin, and co-founder and CTO Jordan Noone worked on SpaceX’s Dragon capsule program. Ellis said Relativity’s approach won’t just unlock cost savings due to automation, it will also provide clients with the ability to launch payloads that weren’t possible with previous launch vehicle design constraints.
