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 Semi’s official battery capacity leaked by California regulators
A California regulatory filing just confirmed the exact battery size inside each Tesla Semi variant.
A regulatory filing published by the California Air Resources Board in April 2026 has put official numbers on what Tesla Semi owners and fleet buyers have long wanted confirmed: the exact battery capacities of both the Long Range and Standard Range Semi truck variants. CARB is California’s independent air quality regulator, and it certifies zero-emission powertrains before they can be sold or operated in the state. When a manufacturer submits a vehicle for certification, the resulting executive order becomes a public document, making it one of the most reliable sources for confirmed production specs on any EV.
The document lists two certified powertrain configurations. The Long Range Semi carries a usable battery capacity of 822 kWh, while the Standard Range version comes in at 548 kWh. Both use lithium-ion NCMA chemistry and share the same peak and steady-state motor output ratings of 800 kW and 525 kW respectively. Cross-referencing Tesla’s published efficiency figure of approximately 1.7 kWh per mile under full load, the 822 kWh pack supports roughly 480 miles of real-world range, which aligns closely with Tesla’s advertised 500-mile figure for the Long Range trim. The 548 kWh Standard Range pack works out to approximately 320 miles, again consistent with Tesla’s stated 325-mile target.
Here is a direct comparison of the two versions based on the CARB filing and published specs:
| Tesla Semi Spec | Long Range | Standard Range |
| Battery Capacity | 822 kWh | 548 kWh |
| Battery Chemistry | NCMA Li-Ion | NCMA Li-Ion |
| Peak Motor Power | 800 kW | 525 kW |
| Estimated Range | ~500 miles | ~325 miles |
| Efficiency | ~1.7 kWh/mile | ~1.7 kWh/mile |
| Est. Price | ~$290,000 | ~$260,000 |
| GVW Rating | 82,000 lbs | 82,000 lbs |
The timing of this certification is not incidental. On April 29, 2026, Semi Programme Director Dan Priestley confirmed on X that high-volume production is now ramping at Tesla’s dedicated 1.7-million-square-foot facility in Sparks, Nevada. A key advantage of the Nevada location is vertical integration: the 4680 battery cells powering the Semi are manufactured in the same complex, eliminating the supply chain bottleneck that had delayed the program for years.
Tesla’s long-term goal is to reach a production capacity of 50,000 trucks annually at the Nevada factory, which would represent roughly 20 percent of the entire North American Class 8 market. With CARB certification now in hand and the production line running, the regulatory and manufacturing groundwork for that target is in place.
Tesla became the first company to pass the United States government’s new Advanced Driver Assistance Systems (ADAS) testing with the Model Y, completing each of the new tests with a passing performance.
In a landmark announcement on May 7, the National Highway Traffic Safety Administration (NHTSA) declared the 2026 Tesla Model Y the first vehicle to pass its newly ADAS benchmark under the New Car Assessment Program (NCAP).
Model Y vehicles manufactured on or after November 12, 2025, met rigorous pass/fail criteria for four newly added tests—pedestrian automatic emergency braking, lane keeping assistance, blind spot warning, and blind spot intervention—while also satisfying the program’s original four ADAS requirements: forward collision warning, crash imminent braking, dynamic brake support, and lane departure warning.
The NHTSA has just officially announced that the 2026 @Tesla Model Y is the first vehicle model to pass the agency’s new advanced driver assistance system tests.

NHTSA administration Jonathan Morrison hailed the achievement as a milestone:
“Today’s announcement marks a significant step forward in our efforts to provide consumers with the most comprehensive safety ratings ever. By successfully passing these new tests, the 2026 Tesla Model Y demonstrates the lifesaving potential of driver assistance technologies and sets a high bar for the industry. We hope to see many more manufacturers develop vehicles that can meet these requirements.”
The updates to NCAP, finalized in late 2024 and effective for 2026 models, reflect growing recognition that ADAS features are no longer optional luxuries but essential tools for preventing crashes.
Pedestrian automatic emergency braking, for instance, targets one of the fastest-rising causes of roadway fatalities, while blind spot intervention and lane keeping assistance address common sources of side-swipes and run-off-road incidents. By incorporating objective, performance-based evaluations rather than mere presence of the technology, NHTSA aims to give buyers clearer data on real-world effectiveness.
This milestone arrives at a pivotal moment when vehicle autonomy is transitioning from science fiction to everyday reality.
Tesla’s Full Self-Driving (FSD) software and the impending rollout of robotaxis underscore a broader industry shift toward higher levels of automation. Yet regulators and consumers remain cautious: safety data must keep pace with technological ambition.
The Model Y’s perfect score on these ADAS benchmarks validates that current driver-assist systems—when engineered rigorously—can dramatically reduce human error, which still accounts for the vast majority of crashes.
For Tesla, the result reinforces its long-standing claim of building the safest vehicles on the road. More importantly, it signals to the entire auto sector that meeting elevated federal standards is achievable and expected.
As autonomy edges closer to Level 3 and beyond, where drivers may disengage more fully, such independent verification becomes critical. It builds public trust, informs purchasing decisions, and accelerates the development of systems that could one day eliminate tens of thousands of annual traffic deaths.
In an era when software-defined vehicles promise transformative mobility, the 2026 Model Y’s NHTSA triumph is more than a manufacturer accolade—it is a regulatory green light that autonomy’s future must be built on proven, testable safety foundations. The bar has been raised. The industry, and the roads we share, will be safer for it.
Tesla is going to fix the nearly 219,000 vehicles that it recalled due to an issue with the rearview camera with a simple software update, giving owners no need to travel to a service center to resolve the problem.
Tesla is formally recalling 218,868 U.S. vehicles after regulators discovered a software glitch that can delay the rearview camera image by up to 11 seconds when drivers shift into reverse.
The affected models include certain 2024-2025 Model 3 and Model Y, as well as 2023-2025 Model S and Model X vehicles running software version 2026.8.6 and equipped with Hardware 3 computers. The National Highway Traffic Safety Administration (NHTSA) determined the lag violates Federal Motor Vehicle Safety Standard 111 on rear visibility and could increase crash risk.
Yet this is no ordinary recall. Owners do not need to schedule a service-center visit, hand over keys, or wait for parts.
Tesla fans call for recall terminology update, but the NHTSA isn’t convinced it’s needed
Tesla identified the issue on April 10, halted further deployment of the faulty firmware the same day, and began pushing a corrective over-the-air (OTA) software update on April 11.
By the time the NHTSA posted the recall notice on May 6, more than 99.92 percent of the affected fleet had already received the fix. Tesla reports no crashes, injuries, or fatalities linked to the glitch.
The episode underscores a deeper problem with regulatory language. For decades, “recall” meant hauling a vehicle to a dealership for hardware repairs or replacements. That definition no longer fits software-defined cars. When a fix arrives wirelessly in minutes — identical to an iPhone update — the term evokes unnecessary alarm and misleads the public about the actual risk and remedy.
Elon Musk has repeatedly called for exactly this change. After earlier NHTSA actions, he stated plainly: “The terminology is outdated & inaccurate. This is a tiny over-the-air software update.” On another occasion, he added that labeling OTA fixes as recalls is “anachronistic and just flat wrong.”
The terminology is outdated & inaccurate. This is a tiny over-the-air software update. To the best of our knowledge, there have been no injuries.
— Elon Musk (@elonmusk) September 22, 2022
Musk’s point is simple: regulators must evolve their vocabulary to match the technology. Traditional recalls involve physical intervention and downtime; OTA updates do not. Retaining the old label distorts consumer perception, inflates perceived defect rates, and slows the industry’s shift to faster, safer software iteration.
Tesla’s rapid, remote remedy demonstrates the safety advantage of over-the-air capability. Problems that once required weeks of dealer appointments are now resolved in hours, often before most owners notice. As more automakers adopt software-first designs, the entire regulatory framework needs to catch up.
Updating “recall” terminology would align language with reality, reduce public confusion, and recognize that modern vehicles are no longer static hardware — they are continuously improving computers on wheels.
For the 219,000 Tesla owners involved, the process is already complete. The camera works, the car is safe, and no one left their driveway. That is the new standard — and the vocabulary should reflect it.
