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.”

Tesla is sending its humanoid Optimus robot to the Boston Marathon
Tesla’s Optimus robot is heading to the Boston Marathon finish line
Tesla’s Optimus humanoid robot will be stationed at the Tesla showroom at 888 Boylston Street in Boston, right along the final stretch of the Boston Marathon today, ready to cheer on runners and pose for photos with spectators.
According to a Tesla email shared by content creator Sawyer Merritt on X, Optimus will be at the Boston Boylston Street showroom on April 20, coinciding with Marathon Monday weekend. The Boston Marathon finishes on Boylston Street, and the surrounding area draws hundreds of thousands of spectators along with international broadcast coverage. Placing Optimus there puts it in front of a massive public audience at zero advertising cost.
Just got this email. @Tesla’s Optimus robot is coming to Boston.

The Tesla showroom is at 888 Boylston Street, between Gloucester Street and Fairfield Street. The final mile of the marathon runs directly along Boylston Street, with runners passing the big stores before reaching the finish line at Copley Square.
Optimus was first announced at Tesla’s AI Day event on August 19, 2021, when Elon Musk presented a vision for a general-purpose robot designed to take on dangerous, repetitive, and unwanted tasks. In March 2026, Optimus appeared at the Appliance and Electronics World Expo in Shanghai, where on-site staff stated that mass production of the robot could begin by the end of 2026. Before that, it showed up at the Tesla Hollywood Diner opening in July 2025 and at a Miami showroom event in December 2025.
Tesla’s well-calculated display of Optimus gives the public a low-pressure first encounter with a robot that Tesla is preparing to soon deploy at scale. The company has previously indicated plans to manufacture Optimus robots at its Fremont facility at up to 1 million units annually, with an Optimus production line at Gigafactory Texas targeting 10 million units per year.

Musk has said that Optimus “has the potential to be more significant than the vehicle business over time,” and separately that roughly 80 percent of Tesla’s future value will come from the robot program. Whether that holds depends on production execution. For now, Boston gets a preview of what that future looks like, standing at the finish line on Boylston Street while 32,000 runners pass by.

Tesla expands Unsupervised Robotaxi service to two new cities
This expansion builds directly on Tesla’s existing operations. Robotaxi has been ramping unsupervised rides in Austin for months and maintains activity in the San Francisco Bay Area.
Tesla has taken a major step forward in its autonomous ride-hailing ambitions.
On April 18, the company’s official Robotaxi account announced that Robotaxi service is now rolling out in Dallas and Houston, Texas. The update signals the rapid scaling of unsupervised autonomous operations in the Lone Star State.
The announcement includes a compelling 14-second video captured from inside a Model Y. Shot from the passenger perspective, the footage shows the vehicle navigating suburban roads in both cities with zero driver intervention, with no Safety Monitor to be seen.

This expansion builds directly on Tesla’s existing operations. Robotaxi has been ramping unsupervised rides in Austin for months and maintains activity in the San Francisco Bay Area.
With Dallas and Houston now live, Texas hosts three active hubs—an impressive concentration that triples the company’s Lone Star footprint in just weeks. The move aligns with Tesla’s Q4 2025 earnings guidance, which outlined a broader H1 2026 rollout across seven U.S. cities, including Phoenix, Miami, Orlando, Tampa, and Las Vegas.
Texas offers favorable regulations, high ride-share demand, and relatively straightforward suburban-to-urban driving patterns ideal for early autonomous scaling. While initial geofences appear modest—roughly 25 square miles per city—Tesla has historically expanded these zones quickly as it gathers real-world data.
Tesla confirms Robotaxi expansion plans with new cities and aggressive timeline
Unsupervised operation marks a critical milestone: passengers can summon, ride, and exit without safety drivers, a leap beyond many competitors still requiring human oversight.
For Tesla, the implications are significant. Successful scaling in major metros could accelerate the transition to a fully driverless fleet, unlocking new revenue streams and validating years of Full Self-Driving investment.
Riders gain convenient, potentially lower-cost mobility, while the company edges closer to Elon Musk’s vision of Robotaxis transforming urban transport.
As Tesla pushes into more cities this year, today’s launch in Dallas and Houston underscores its momentum. Hopefully, Tesla will be able to expand unsupervised rides to another U.S. state soon, which will mark yet another chapter in this short-but-encouraging Robotaxi story.

Tesla is pushing Robotaxi features to owner cars with Spring Update
Tesla has quietly begun rolling out one of its most forward-looking Robotaxi-inspired features to existing customer vehicles.
Tesla is starting to push Robotaxi features to owner cars, and the first instances are coming as the Spring 2026 Update starts to roll out.
Tesla has quietly begun rolling out one of its most forward-looking Robotaxi-inspired features to existing customer vehicles.
With the 2026 Spring Update (version 2026.14+), the rear passenger display now features a fully interactive navigation map that works while the car is driving — a capability previously reserved for Tesla Robotaxi.
First look at Tesla’s v2026.14.1 Spring Update.
🧭Rear screen interactive map #teslaupdate #tesla #teslasrpingupdate pic.twitter.com/yH3T4U8qHp— Sergiu Mogan (@sergiumogan) April 17, 2026
Until now, Tesla’s rear displays have been largely limited to media controls, climate settings, and static route overviews. The new interactive map transforms the backseat into an active navigation hub, exactly the kind of passenger-first interface Tesla has been prototyping for its driverless fleet.
In a Robotaxi, where no one sits behind the wheel, every rider will need intuitive, real-time map access. By shipping this UI into thousands of owner cars months ahead of the Cybercab’s planned unveiling, Tesla is stress-testing the software in real-world conditions and giving loyal customers an early taste of the autonomous future.
The rollout is still in its early wave. Only a small number of vehicles have received 2026.14.1 so far, but the feature is expected to expand rapidly in the coming weeks. Owners of Model S, Model X, Model 3, Model Y, and Cybertruck are all eligible.
For buyers of the new Signature Edition Model S and X Plaid vehicles — whose deliveries begin in May — the update will likely arrive shortly after they take delivery, meaning the final chapter of Tesla’s flagship lineup will ship with cutting-edge Robotaxi preview tech baked in.
Elon Musk has long emphasized that Tesla ships supporting infrastructure well before new products launch. This rear-map rollout is a textbook example of that philosophy — quietly preparing both the software and the customer base for a world of fully driverless rides.
While the interactive map may seem like a modest convenience upgrade on the surface, its deeper purpose is unmistakable. Tesla is using its massive installed base of vehicles as a proving ground for the exact passenger experience that will define the Robotaxi era.
For current owners, it’s a free preview of tomorrow’s mobility; for the company, it’s invaluable data and real-world validation before the Cybercab hits the streets.
