Relativity Space and TriSept Sign Launch Services Agreement (LSA) for a Dedicated Rideshare Manifest Focused on Providing Access to Space for Large and Small Satellite Payload Missions

LOS ANGELES & CHANTILLY, Va. ()–Supporting a rideshare manifest with a mix of small and large satellites, TriSept Corporation has selected Relativity Space for a full mission aboard Relativity’s Terran 1, the world’s first entirely 3D printed rocket.

Under the signed agreement, TriSept has secured a full mission on Terran 1 as early as 2022. The launch will take place from one of Relativity’s launch sites at Cape Canaveral or Vandenberg Air Force Base.

TriSept, a leading provider of launch integration and program management services, primarily serves best-in-class commercial and U.S. government customers including the Department of Defense (DoD), NASA, the NRO, and classified payload missions supporting national security and innovation.

Relativity Space, the first company to 3D print an entire rocket and build the largest metal 3D printers in the world, is disrupting aerospace with the first and only aerospace factory to integrate 3D printing, artificial intelligence, and autonomous robotics, allowing rockets to be built in less than 60 days, with 100x fewer parts and a radically simplified supply chain.

Relativity will demonstrate its industry-defining advantage to offer both government and commercial customers affordable access to space, in Low Earth Orbit (LEO) and beyond. TriSept is a long-time go-to launch integration provider in the US and UK space markets, enabling the launch of more than 200 satellites, including a broad range of small rideshare spacecraft into LEO, MEO and GEO orbits.

“We are excited to partner with TriSept, a seasoned leader in providing innovative solutions for its customers in mission management, rideshare brokerage, and launch integration,” said Tim Ellis, Co-Founder and CEO of Relativity Space. “At Relativity, we are revolutionizing access to space through our disruptive approach to manufacturing and are fortunate to work with companies like TriSept that reflect our forward-thinking mission and relentless pursuit to build humanity’s multi-planetary future.”

As a well-trusted, veteran launch integration provider in the US and UK space market, TriSept is already in discussions with several large and small satellite developers with missions to launch within the timeframe covered under the launch services agreement with Relativity.

“Relativity is building something our team is very excited about and their Terran 1 rocket architecture is designed to accommodate the evolving needs of our government and commercial customers,” said Rob Spicer, TriSept CEO. “Because Terran 1 is a larger launch vehicle with more performance to LEO, it offers our prime and rideshare customers with bigger satellites a low-cost alternative for launch.”

Relativity has recently achieved significant technical, commercial, infrastructure, and team momentum. This agreement with TriSept is the seventh publicly announced launch customer for Relativity, following partnership announcements with both commercial and government industry leaders such as Lockheed Martin, Iridium, and NASA, to name a few.

About Relativity Space

Relativity is building humanity’s multiplanetary future. We invented a new approach to design, build, and fly our own rockets, starting with Terran 1 – the world’s first entirely 3D printed rocket.

As a vertically integrated technology platform, Relativity is at the forefront of an inevitable shift toward software-defined manufacturing. By fusing 3D printing, artificial intelligence, and autonomous robotics, we are pioneering the factory of the future. Disrupting 60 years of aerospace, Relativity offers a radically simplified supply chain, building a rocket with 100x fewer parts in less than 60 days.

We believe in a future where interplanetary life fundamentally expands the possibilities for human experience. Our long-term vision is to upgrade humanity’s industrial base on Earth and on Mars.
