Long Beach: The New Site for Relativity Space’s 3D Printed Rockets

Commercial space companies are looking to get their technology to orbit. This decade could mark a big shift in the race for space domination, with a few big names taking over Low Earth Orbit (LEO) and beyond. Moreover, as NASA begins to transition the domain of LEO to the commercial space industry, these enterprises are preparing to make up the backbone of their engines, rockets, and space crew vehicles to travel beyond Earth. On that path, is Relativity Space, a Los Angeles based startup that is quickly expanding its commercial orbital launch services. Just today, CEO and co-founder, Tim Ellis, announced that it has secured new headquarters in Long Beach, California.

The 120,000 square feet site will house both the company’s business operations and an unprecedented manufacturing facility, as they will be producing the their 3D printed rocket, the Terran 1, a launch vehicle that the company plans to build in only 60 days from raw materials and by 3D printing the structure as well as the engine. The company is already printing large-scale, flight-ready parts of their Terran 1 rocket and this move to the new headquarters will give them five times the space to add more Stargate 2.0 3D printers, print higher structures and parts, even assemble and load rocket sections onto trucks to ship to Cape Canaveral for launch.
“Relativity is disrupting nearly sixty years of prior aerospace technology by building a new manufacturing platform using robotics, 3D printing, and Artificial Inteligence (AI). With no fixed tooling, Relativity has enabled a massive part count and risk reduction, increased iteration speed and created an entirely new value chain,” said Ellis. “I’m confident our autonomous factory will become the future technology stack for the entire aerospace industry.”

Relativity Space integrates machine learning, software, robotics with metal additive manufacturing technology to try to build an almost entirely 3D printed rocket. It claims that it is the first company to utilize additive manufacturing and robotics to build an entire launch vehicle. Relativity’s platform vertically integrates intelligent robotics and 3D autonomous manufacturing technology to build Terran 1, which has 100 times lower part count than traditional rockets and a radically much simpler supply chain. The aerospace startup hopes to launch the world’s first entirely 3D printed rocket into orbit and enter commercial service in 2021.

The autonomous factory will have high ceilings, at 36 feet, that will enable the company to print taller structures, and the 120,000 sq. ft. space will have a 300 person capacity, that’s a pretty big move, considering they currently employ 150 people across their Los Angeles office space and production facilities, their factory building at the NASA Stennis Space Center in Mississipi, and at the Launch Complex 16 in Cape Canaveral, Florida.

The new headquarters facility will not only provide a new blank slate to support innovation and creation, but it is also located in the heart of Southern California’s next-generation aerospace community. With more than 35 aerospace companies in the area, the place is keeping up with a long-standing tradition as an aerospace hub, with space launch-service providers, satellite makers, and even drone developers coexisting.

“Long Beach has an extensive history as a leader in aerospace and aviation, and now we are at the forefront of the space economy,” indicated California Senator Lena Gonzalez. “We are excited to welcome Relativity to our ever-growing community of innovative tech companies.”

While 70th District Assemblymember Patrick O’Donnell said: “I am proud to welcome Relativity Space to our community and wish them success as they go higher, further and faster to the stars. The aerospace industry is undergoing an economic resurgence in Long Beach, providing the prospects of good-paying jobs and further opening up the bounds of space for research.”

Relativity has already begun migrating staff to its new headquarters and is transitioning its patented additive manufacturing infrastructure as it builds out the first-ever mostly autonomous rocket factory. The factory will house all of the production for Terran 1, including the Aeon engine assembly, as well as integrated software, avionics, and materials development labs. The new facility enables the production of almost the entire Terran 1 rocket, including an enlarged fairing, now accommodating double the payload volume. The company claims that the combination of agile manufacturing and payload capacity makes Relativity the most competitive launch provider in its class, meeting the growing demands of an expanding satellite market.

The first stage of Terran 1 is powered by nine Aeon-1 engines, fueled by liquid oxygen (LOX) and methane; while the second stage is powered by a single restartable Aeon-1 Vacuum engine. Terran 1 will be able to carry a payload of 1250 kg to LEO, and 900 kg to a 500 km sun-synchronous orbit. The first test launch is planned for late 2020 at the Launch Complex 16 at Cape Canaveral.

The new headquarters and factory mark another milestone in Relativity’s steady execution towards its first launch. Relativity recently closed a $140 million funding round led by Bond and Tribe Capital and has already secured a launch site Right of Entry at Cape Canaveral Launch Complex 16, an exclusive-use Commercial Space Launch Act (CSLA) agreement for several NASA test sites, including the E4 Test Facility at the NASA Stennis Space Center, and a 20-year exclusive use lease for a 220,000 square feet factory also at the NASA Stennis Space Center.

This type of initiative broadens the range of opportunities and continues to build the fundamental basis of the future of aerospace exploration. Rockets, like Terran 1, could move forth more science, better technology, and advance research significantly. In 2019, we saw many payloads delivered to the International Space Station (ISS), all of them filled with scientific experiments, medical research and much more, and all of them aimed at improving human life on Earth and in space. With more payload, launch, and delivery options satellites, exploration and space stations could become much less expensive. Cost reduction through competition could make space a much more accessible place. Relativity Space is breaking ground with the technology, allowing its engineers to create what they can imagine, and with this new rocket facility, the startup could become a leading force in the industry.

Relativity Space 3D Prints 11-Foot-Tall Fuel Tank with Stargate 3D Printer

Relativity Space is not alone in wanting to 3D print rockets – there are plenty of companies with the goal of doing just that. What makes Relativity stand out, however, is that it has the means to 3D print entire rockets with almost no intervention from humans. The company’s massive Stargate 3D printer utilizes 18-foot-tall robotic arms equipped with lasers that can melt metal wire. Those robotic arms have the ability to stream about eight inches’ worth of metal onto a large turntable in just a second’s time. Directed by custom software, the robotic arms are capable of producing the entire body of the rocket in one piece.

Using a giant 3D printer allows Relativity Space to reduce the part count of a typical rocket from 100,000 to 1,000. This, needless to say, greatly saves on time, labor and money, which in turn saves customers millions of dollars per launch. Relativity intends for its rockets to carry large payloads, too, up to the size of a small car, which is six times the capability of its competitors, according to the company.

Relativity is a young company, founded in 2015, and just this year completed its Series B funding. It has already accomplished a great deal with the Stargate 3D printer, however, and its latest milestone was the 3D printing of an 11-foot-tall aluminum fuel tank. The 3D printer worked for three weeks to complete the tank, which will next be taken to NASA’s Stennis Space Center in Mississippi. Relativity Space signed an agreement with NASA for exclusive use of Stennis Space Center’s 25-acre E4 Test Complex. The facility also includes four large test cells rated for entire vehicles and engines and 15,000 square feet of specialized infrastructure. Relativity is investing its own capital to build upon the existing site, and is creating a permanent team to lead testing operations.

The agreement between Relativity and Stennis Space Center is Stennis’ first ever and will be in place for 20 years. Relativity Space will use the site to carry out complete development, qualification and acceptance testing of the Terran 1 rocket, a launch vehicle designed from scratch for constellation deployment and resupply. According to Relativity, the rocket will be one of the most cost-effective launch vehicles in the world.

Over the next year or two, Relativity Space plans to spend its time working on the development of the Terran 1’s first stage. The company is aiming for late 2020 or early 2021 for its first commercial launch. Long-term goals are a bit more out there – Relativity wants to build the first rocket on Mars. But with all the serious talk of going to Mars lately and the continued development of plans for building settlements on the Red Planet, Relativity’s goals may not be so far-out after all.
