Relativity Space “closer and closer” to first launch of a fully 3D-printed rocket
Relativity Space, a Long Beach, California-based aerospace startup, aims to alter the manufacturing process of rockets forever by 3D-printing almost every piece of their orbital-class Terran rockets.
The company was co-founded in 2015 by CEO Tim Ellis (departing Blue Origin) and Jordan Noone (departing SpaceX), with both engineers leaving their positions at these industry giants with one goal in mind: build and launch the world’s first 3D-printed orbital rocket.
In the last two and a half years, the startup has managed to raise nearly $1.3 billion through private investors including Baillie Gifford, Blackrock, BOND, Fidelity, General Catalyst, and Mark Cuban. That amount of investment makes Relativity one of the most valuable and best-funded private aerospace companies in recent history – second only to Elon Musk’s SpaceX, which has raised more than $7.7 billion in about a decade.
Relativity’s rocket manufacturing facility, “The Factory of the Future,” is located in Long Beach, California, and is home to Stargate – the world’s largest 3D printer. According to Ellis, Stargate is capable of printing virtually all of the parts required for the world’s first 3D-printed rocket, Terran 1, and the first fully reusable 3D-printed rocket, Terran R, from raw material to flight in just 60 days. To accomplish that unprecedented feat and create the largest metallic 3D-printed structures ever attempted, Relativity has developed multiple proprietary alloys.
Beyond its extremely exotic manufacturing approach, Terran 1 is a fairly standard two-stage rocket primarily designed to launch small satellites to low Earth orbit (LEO). The first stage is powered by nine Aeon 1 engines, each producing around 23,000 pounds of force (100 kN) at launch and 25,400 lbf (113 kN) in the vacuum of space. The engine is powered by liquid methane (LCH4) and liquid oxygen (LOx) and is made out of several proprietary 3D-printed alloys. The second stage is powered by one Aeon 1 Vacuum engine capable of producing up to 28,300 lbf (126 kN) of thrust in a vacuum thanks to a much larger nozzle. Terran 1 is designed to carry up to 1,250 kilograms to a very low Earth orbit (LEO).
Relativity is growing quickly and has expanded to nearly 600 employees in just a few years. Aside from their headquarters and manufacturing facility in Long Beach, CA, Relativity has planted their flag at Cape Canaveral Space Force Station (CCSFS), where it’s developing Launch Complex 16 (LC-16) for Terran 1 and Terran R. There, a team of infrastructure engineers and technicians are currently building the launch facilities that will support Terran 1’s launch debut. A separate team at Mississippi’s NASA Stennis Space Center is continually testing the startup’s engines and rocket stages.
In a recent tweet, CEO Tim Ellis revealed that the company had completed a record nine successful Aeon engine tests in a single day. The CEO also stated that stage integration for Terran 1’s launch debut was making “amazing progress.”
Relativity had previously planned for Terran 1’s first launch to take place by the end of 2021. That debut has since slipped to “early 2022”, while the company hopes its far larger reusable Terran R rocket will debut in 2024.
Relativity was recently selected by NASA to be one of 12 companies to provide launch services for the agency’s Venture-Class Acquisition of Dedicated and Rideshare (VADR) missions, providing new opportunities for more risk-tolerant science and technology payloads and fostering a growing U.S. commercial launch market. “The VADR contract will provide a broad range of Federal Aviation Administration-licensed commercial launch services capable of delivering payloads ranging from CubeSats to Class D missions to a variety of orbits. These small satellites and Class D payloads tolerate relatively high risk and serve as an ideal platform for technical and architecture innovation, contributing to NASA’s science research and technology development.”
SpaceX is preparing for the 13th integrated flight test of its Starship system, with a targeted launch as early as Thursday, July 16. The 90-minute launch window opens at 5:45 p.m. CT from Starbase in South Texas.
This comes roughly seven weeks after Flight 12 on May 22, underscoring the company’s accelerating pace in its rapid development campaign. The mission will use the latest Starship and Super Heavy V3 vehicles equipped with Raptor 3 engines. Booster 20 will attempt a controlled boostback burn, followed by a splashdown in the Gulf of Mexico, while Ship 40 will follow a suborbital trajectory.

Key objectives for Flight 13 will include demonstrating reliable stage separation, engine performance under various conditions, and controlled reentry.
A major milestone for Flight 13 is the first deployment of 20 next-generation Starlink V3 satellites. These satellites feature advanced laser links for inter-satellite communication, deployable solar arrays, and onboard cameras, six of which will capture imagery of Starship’s heat shield during flight.
Several heat shield tiles on Ship 40 will be painted white to serve as imaging targets, while additional experiments test upgraded tiles on aft flaps, modified attachments on the aft skirt, and load-sensing tiles to measure stresses. The upper stage will also attempt a single Raptor engine relight in space before a targeted splashdown in the Indian Ocean.
These tests build directly on lessons from Flight 12, which introduced the V3 configuration but encountered issues including a booster flip anomaly during boostback and an engine-out event on the ship. Hardware and software modifications on Booster 20 and Ship 40 aim to improve engine relight reliability, startup sequencing, and overall robustness.

The short interval between Flights 12 and 13 highlights SpaceX’s iterative approach. Elon Musk has repeatedly emphasized that Starship launches will become “incredibly common” in the coming years.
The company envisions scaling to rates as high as one launch per hour within 4-5 years, potentially enabling thousands of flights annually. Such cadence is essential for Starship’s goals: establishing orbital refueling for lunar and Mars missions, deploying massive satellite constellations, and making life multiplanetary.
With each flight, Starship edges closer to full reusability and operational maturity. Success on July 16 would mark another step toward routine access to space and the ambitious vision of humanity becoming a spacefaring civilization.
Tesla shared a striking video showcasing the decommissioning of the original Model S and Model X assembly line at its Fremont Factory in Northern California. Completed in just 46 days, the teardown involved heavy machinery dismantling concrete pits, removing robotic arms and conveyors, and clearing the space for new production.
The post, captioned “End of an era,” captured both the end of a historic chapter and Tesla’s aggressive pivot toward its next major initiative, Optimus.

The decision to retire the Model S and Model X originated during Tesla’s Q4 2025 Earnings Call in late January 2026. CEO Elon Musk announced that production of the company’s flagship sedan and SUV would wind down by the end of Q2 2026, describing it as bringing the programs to an “honorable discharge.”
Custom orders ceased around early April 2026, with the final vehicles rolling off the line in early May. A special signature delivery ceremony on May 20 marked the emotional close for these vehicles, which had defined Tesla’s early success and luxury EV segment since the Model S launch in 2012.
The primary reason for tearing down the lines was to repurpose the valuable factory floor space for high-volume production of Tesla’s Optimus humanoid robot. Musk had indicated on Earnings Calls that the Fremont S/X line would be replaced by a dedicated Optimus manufacturing line targeting a capacity of one million units per year.
This move aligns with Tesla’s broader strategic shift from traditional vehicle manufacturing toward robotics and artificial intelligence, leveraging the company’s expertise in autonomy, AI training, and high-volume production.
Optimus, Tesla’s general-purpose humanoid robot, is designed to perform repetitive or dangerous tasks in factories, warehouses, and eventually homes. Powered by Tesla’s AI and Neural Networks, it aims to be a versatile, affordable platform. Production of Optimus Gen 3 is already underway in limited form at Fremont, with full-scale output on the converted line expected to begin in late July or August.
Tesla is targeting rapid scaling, with internal ambitions pointing toward tens or even hundreds of thousands of units annually by the end of 2026.
Longer-term, Tesla is constructing a much larger second-generation Optimus facility at Giga Texas, with potential capacity reaching millions of units per year. The company views Optimus as a transformative product that could eventually surpass its automotive business in scale and value, enabling widespread deployment of useful robots across industries. CEO Elon Musk has even predicted it would be the most popular product of all-time.
As one era closes at Fremont, another is rapidly taking shape.
Elon Musk posted a candid admission on his social media platform X on June 9, declaring that he had been “clearly wrong” about Anthropic. The statement marked a notable reversal from his earlier skepticism toward the AI company.
In September, Musk had written, “Winning was never in the set of possible outcomes for Anthropic,” reflecting his view at the time that the startup had lacked the foundation or even the trajectory to succeed in what is an incredibly intense race for advanced artificial intelligence.
Musk’s latest post came amid discussion of Anthropic’s reliance on external compute resources. He praised the company’s progress, stating that Anthropic is “obviously currently the leader in AI” and that “no company has released a model as good as Mythos/Fable,” with expectations of a strong follow-up in Mythos 2.
The tone shifted dramatically from dismissal to acknowledgement of superior performance.
I was clearly wrong about Anthropic. They are obviously currently the leader in AI. No company has released a model as good as Mythos/Fable and they will undoubtedly have Mythos 2 ready soon.
And I would never cut them off in a way that hurt them badly, even as a competitor.…

The context of Musk’s comments added significance. Anthropic has been operating under a recent compute deal with SpaceXAI, Musk’s AI infrastructure-focused venture. The pair entered a short-term GPU lease agreement initiated in May, providing Anthropic access to critical computing power for training and deploying its frontier models.

Some observers had speculated that Musk could leverage this dependency to disadvantage a rival. Musk directly addressed the possibility, writing, “I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style.”
To support his commitment to ethical competition, Musk referenced concrete examples from his other companies. Tesla famously open-sourced its entire portfolio of electric vehicle patents in 2014. The move was designed to accelerate the global adoption of sustainable transportation technology rather than protect proprietary advantages.
Tesla also made its Supercharger network available to competing electric vehicle manufacturers, transforming what could have remained an exclusive charging ecosystem into a shared infrastructure that benefits the broader industry and reduces barriers for EV adoption.
Musk further pointed to SpaceX’s practices, noting that the company launches satellites for competing commercial systems “with no increase in price or use of unfair terms.” He extended the principle to his social platform, observing that “even my worst enemies attack me on this platform,” underscoring preference for open discourse over retaliation.
These examples have illustrated Musk’s long-standing philosophy that long-term technological progress is best served by open competition and infrastructure sharing rather than leveraging market power to stifle rivals. In the fast-evolving AI sector, where compute resources and model capabilities determine leadership, Musk’s stance suggests a willingness to compete on innovation and performance alone.
Musk’s admission arrives as SpaceXAI itself advances its own frontier models while maintaining business relationships across the ecosystem. By publicly correcting his earlier assessment and reaffirming principles of fair play, Musk highlights a model of competition that prioritizes advancement of the field over short-term tactical advantages.
