Relativity Space raised $500 million to help it build its 3D rocket ships in a round led by Tiger Global Management, CNBC reported on Tuesday.
The raise, one of the largest this year for a Los Angeles startup, would reportedly value the company at $3.2 billion and put the region at the center of a new wave of high-value space companies.
Earlier this year, Hawthorne-headquartered SpaceX raised $1.9 billion at a reported $46 billion valuation.
Neither Relativity nor Tiger Global could be reached for comment.
Relativity was created by two twenty-somethings and seeks to revolutionize spaceflight by building the world's first 3D-printed rocket with its first iteration called Terran 1. The process is cheaper than traditional manufacturing and CEO and co-founder Tim Ellis, an alum of the Jeff Bezos-led space company Blue Origin, aims to eventually automate rocket-making on Mars.
Relativity has picked up steam recently landing a contract with Lockheed Martin to build 3D projectiles for an experimental NASA mission to test cryogenic fluid management capabilities, key to establishing a sustainable presence on the moon and sending crewed missions to Mars. And in June it struck a deal with the U.S. Air Force's 30th Space Wing to develop rocket launch facilities at Vandenberg Air Force Base.
Last year the company closed a $140 million Series C round led by Bond and Tribe Capital in October. Relativity is also backed by investors Playground Global, Y Combinator, Social Capital, and Mark Cuban.
Those funds helped build a new headquarters in Long Beach where the company is likely to expand the development of the Terran 1. It comes months after co-founder Jordan Noone resigned as chief technology officer and became an executive advisor in what he said was preparation for starting another venture.

3D Printing Could be a Game-Changer For Space Exploration, so Why is NASA Reluctant to Use it?
Nov 18 2020
When Perseverance arrives on Mars early next year, it will be the first landfall for a rover carrying 3D-printed metal parts and a small victory for proponents of the technique in the high-cost, high-risk world of the U.S. aerospace program.
NASA's Jet Propulsion Laboratory, nestled in the foothills of La Cañada Flintridge, has seen a slow cultural shift over the last decade toward the adoption of 3D printing techniques, more formally known as "additive manufacturing," in spacecraft design. The technology uses lasers to melt metal powder that is layered to precise computer modeling, until that metal takes the shape of whatever engineers need.
For years, 3D printing has been relegated to the realm of nerdy hobbyists, but its adoption by startups and big business has helped push NASA leaders toward accepting more innovation despite the risks. These days, 3D printing has been used on airplane engines, houses, hearing aids, chocolates, Tesla car components and even a pair of Adidas shoes.
"I have seen a 3D printed burrito, and it didn't look as delicious as Chipotle," said Scott Roberts, a JPL materials technologist, with a laugh.
<p>The evolution has been decades-long, and partly propelled by the private sector push of aerospace companies like SpaceX, Relativity Space, Blue Origin, Maxar Technologies and Lockheed Martin.</p><p>While no panacea, some of the benefits of 3D printing come from its ability to save time in the otherwise time-consuming machining process and to engineer bespoke components that cut down on mass and simplify parts. All are crucial, as aerospace missions are often timed to planetary alignment and can cost millions more dollars per kilogram.</p><p>The goal is to use additive manufacturing to enhance performance, solve problems and make parts "you just can't make any other way," Roberts said. "If your schedule is slipping and all of a sudden you have to wait two years, the monetary cost is enormous."</p><p>JPL technologists are still working on understanding its uses and how to improve it. But there remains a culture and learning gap that's prevented its widespread adoption. The largest barrier, however, is the worry by old timers: Why risk screwing up a historic mission and ruining future opportunities by replacing tried-and-true manufacturing techniques?</p><p><br/></p><p class="shortcode-media shortcode-media-youtube">

</p><p><br/></p><p><strong>The Nuts And Bolts of Printing Rover Parts</strong></p><p>Amid planning for the Mars rover mission, Andrew Shapiro, who manages technology formulation at JPL, said he was interested in which parts made sense to manufacture additively and which didn't. </p><p>When Shapiro checked out work on <a href="https://mars.nasa.gov/mars2020/spacecraft/instruments/moxie/" rel="noopener noreferrer" target="_blank">MOXIE</a>, which is <a href="https://dot.la/moxie-mars-2020-rover-2645069343.html" target="_self">testing a technology to produce oxygen on the Red Planet</a> carried by the rover, engineers told him they had a problem sealing its crucial heat exchanger, a complex system with lots of very fine channels. </p><p>"It was very expensive to machine, they were going to blow their budgets and schedules, and it was going to take months," Shapiro said. "My office has advanced technology experiments, so I said, 'I'll fabricate one using additive for you, see if it works. If you like it, use it.'"</p><p>The part was far less expensive to print than it would have been to create through traditional manufacturing methods — and it solved the MOXIE engineers' problems.</p><p>The Perseverance rover, which lands on Mars on Feb. 18, 2021, carries 11 metal parts that were 3D printed. Five of those are on its <a href="https://mars.nasa.gov/news/8759/nasas-new-mars-rover-will-use-x-rays-to-hunt-fossils/" rel="noopener noreferrer" target="_blank">PIXL instrument</a>, which is about the size of a lunchbox and will be used to help the rover search for signs of fossilized microbial life by shooting out X-ray beams.</p><p>The instrument was designed with a two-piece titanium shell that has to be extremely thin, which made traditional machining methods very challenging, time consuming and therefore costly. Using metal 3D printing, JPL outsourced the work to Carpenter Additive, in Camarillo, Calif., which created components that were several times lighter than they would have otherwise been able to achieve.</p><p>The MOXIE heat exchanger, however, was 3D printed in-house at Caltech, which manages JPL. Rather than welding together two separate parts, JPL's engineers 3D printed it in one single piece.</p><p>Andre Pate, the group lead for additive manufacturing at JPL, called the use of 3D metal printing on the rover "a big win for us at JPL."</p><p>"We are trying to convince our own people here who are more conservative and less willing to take on risk -- rightfully so," Pate said. "We're trying to prove that, that there isn't as much risk or that there's ways to mitigate that risk."</p><p><br/></p><p class="shortcode-media shortcode-media-rebelmouse-image">

Its rocket resupply, which recently <a href="https://www.nasa.gov/press-release/spacex-dragon-heads-to-space-station-with-nasa-science-cargo-1" rel="noopener noreferrer" target="_blank">traveled to the International Space Station</a>, had 3D printed parts, Shapiro said.</p><p>Canoo, the electric vehicle company, is also hiring an additive manufacturing lead as it prepares for its first vehicle launch. And of course, Relativity Space is 3D printing rockets with the ultimate goal of doing so on Mars.</p><p>"JPL is very slow moving in this way," Shapiro said. "Places like SpaceX or Maxar, they 3D print dozens of parts. [These] other companies have been quicker to adopt the technology. Interestingly enough, I think we know more about the technology than they do because SpaceX isn't willing to pay a lot of universities to develop models and that kind of thing."</p><p>Plus, Shapiro added, "they all want to keep their stuff secret and don't want to share it with the rest of the world. But the rest of the world passes them by when they do that."</p><p>Regardless, as more of its subcontractors and other aerospace companies use 3D manufacturing techniques, JPL has been pushed to gain a better understanding, and it has shared that expertise with the companies even if lab leadership is less willing to incorporate it themselves, Shapiro said.</p><p>"JPL will actually adopt things more easily from the outside than the inside," Shapiro said. "So it's easier for me to go buy a part from a subcontractor using additive than it is for me to say 'we should design this using additive'."</p><p><br/></p><p class="shortcode-media shortcode-media-rebelmouse-image">

</p><p><br/></p><p>Part of the reason is that NASA management is still reluctant to adopt new untested technologies for building parts that have otherwise been effectively created using longstanding conventional manufacturing processes.</p><p>"So when someone says 'would you...risk a billion dollar mission on it'? You have to argue, it isn't really that risky," Roberts said.</p><p>Several years ago, JPL vendor Lockheed Martin built the spacecraft Juno to collect data and take photos of Jupiter. Lockheed slipped in a couple additive parts into that spacecraft, Shapiro said.</p><p>"They didn't tell us until after it had launched," Shapiro said, noting that "our vendors are willing to go a little further than we are."</p><p>It became the first planetary spacecraft to make use of 3D printed parts, <a href="https://www.engineering.com/3DPrinting/3DPrintingArticles/ArticleID/12572/Junos-3D-Printed-Parts-Survive-Trip-to-Jupiter.aspx" target="_blank">specifically titanium metal brackets</a>.</p><p><strong><span></span>A Slow Start</strong></p><p>The first time Andrew Shapiro — now a JPL thought leader in additive manufacturing — was approached by a colleague about using 3D printing for metal parts was around 11 years ago, when he was the chief technologist of the engineering enterprise division. Shapiro was aware of the tech, but it was not taken seriously for space flight.</p><p>"I told him to go away," Shapiro said. "I said, 'Naw, I don't think this will ever work.'"</p><p>Shapiro said he gave in to his colleague's persistence and traveled to a spin-off company of nearby Sandia Labs in Albuquerque, New Mexico to take a look. Soon, JPL was studying how to create a gradient of metal from, say, steel on one end of a part to titanium on the other, enabling the steel ends of two separate parts to be bolted together more effectively if need be. </p><p>"It turns out this is not easy to do. It took us about 10 years to figure it out," Shapiro said. "That's because that transition between the two metals can create brittle structures that break or fracture."</p><p>JPL ended up sponsoring a slew of studies at universities, with Shapiro urging professors to look into how additive manufacturing works. At the time, Shapiro said, JPL realized nobody understood the process. JPL worked with the universities to set standards so that results were comparable and compatible. Today, every major university with an engineering program in the country has a significant program modeling additive processes. </p><p>Adopting and proving out the technology also required computer power to improve to study variables like air vortices created by a laser hitting metal powder and massive temperature gradients that go from a couple thousand degrees to room temperature in a tiny area, Shapiro said. </p><p>"I don't think the culture is there yet," Shapiro said. "It's being selectively adopted still [but] we haven't turned our whole design force into using additive."</p><p>Roberts said that sometimes it's a matter of an engineer saying " 'Oh man, we need this part,' and to make it traditionally is going to take two years" and that's when additive manufacturing, which can instead make the part in six months, gets its chance.</p><p><strong>Known Unknowns</strong></p><p>Another problem is there aren't great classes out there for teaching 3D printing at JPL's level.</p><p> And, the reality is that some people are intuitively very good, while other engineers just don't think that way, Shapiro said. "Designing parts of a spacecraft really shouldn't be just left to intuition," he said.</p><p>Shapiro said he believes the future of 3D printing includes integrating functions — much like today's phone is a combination of telephone, calendar, calculator and notepads. One example of this might be printing the antenna on a spacecraft directly as part of its structure. But no one knows how to design for this yet, Shapiro said, there's no guidebook or design rules. That's why he is working with colleagues to put together a course and some guidelines.</p><p><br/></p><p class="shortcode-media shortcode-media-html5_video">

"We've just scratched the surface in terms of what the capabilities are."</p><p>For now, Shapiro believes JPL will continue to put more 3D-printed pieces into spacecraft, but doing larger prints like an entire space craft requires a major shift in culture and engineering understanding.</p><p>"It's difficult to answer when will people change their minds," Shapiro said.
