SpaceX’s orbital Starship gains a nose as East Coast prototype makes progress
On May 20th, SpaceX technicians successfully stacked a nosecone on top of the company’s Boca Chica orbital Starship prototype. Simultaneously, a separate team of technicians and engineers have been hard at work building a second similar-but-different Starship prototype near Cape Canaveral, Florida.
Officially confirmed last week by Elon Musk, the SpaceX CEO revealed that the company was not only building two orbital Starship prototypes simultaneously – not news in itself – but that those prototypes were being built as a sort of internal competition between different teams and ideas. The competition is not cutthroat – knowledge is shared between Texas and Florida – but the strategy is fairly similar. In lieu of actual commercial competitors, SpaceX is attempting to compete with itself to more rapidly and effectively develop a brand new launch vehicle – the stainless steel Starship/Super Heavy.
A Starship rises in the East
In just the last week, both SpaceX groups have made major progress. On the East Coast, the general public saw the first photo of SpaceX’s Florida Starship build precisely seven days ago. It appears that SpaceX has more or less taken over a Cocoa, Florida facility known to be the prior home of Coastal Steel, a repeat NASA contractor known for steelwork.
It’s unclear if SpaceX has fully acquired Coastal Steel or is simply partnering with the small company in the early stages of its Florida Starship buildup. Regardless, even from perspectives quite a bit more distant than those available in Texas, it’s clear that the metal workmanship is at least on par with Boca Chica, if not giving them a run for their money.
Admittedly, the playing field is not exactly level. SpaceX’s South Texas team has been working just a few thousand feet away from the unobstructed Gulf of Mexico in conditions that would make for an excellent traditional-aerospace horror show. Aside from a lone tent, all welding, assembly, integration, and testing has been done while fully exposed to the elements. SpaceX’s Florida team appears to have the luxury of an established warehouse – previously used for steelwork – to use as a covered and partially insulated work and staging area. The Florida team effectively had everything they needed (give or take) on hand from the moment work began, while Texas had to quite literally build all of its facilities from nothing.
Be it the facility luxuries or Cape Canaveral’s far larger pool of local aerospace talent, it’s clear that SpaceX’s Florida team will be a competitive force to be reckoned with despite Texas’ apparent head start. In the seven days since the first photos of the Florida Starship were published, SpaceX technicians have almost doubled the height of the largest welded section, raising it from ~5.5m to ~9m (18-30 ft).
Meanwhile, those working inside the staging warehouse continue to crank out 2x9m subsections, already making way for what appears to be the first tapered nose section of the Florida Starship. At this rate, Florida could very well catch up to SpaceX’s Texas Starship just a month or two from now. It’s worth noting that the Florida team does not appear to be involved in any Starhopper activities. SpaceX Boca Chica, on the other hand, has spent a major portion of the last several months building out Starhopper and preparing the odd prototype for untethered hop tests.
The (slightly) Old(er) Guard
Despite Starship Florida’s rapid progress, Starship Texas has not exactly been standing around. In the last week or so, SpaceX technicians and engineers have been simultaneously working on major new integration, assembly, and test campaigns with both Starhopper and the first orbital Starship prototype. A dedicated Starhopper article will come later this week as SpaceX’s South Texas team nears Raptor reinstallation and an untethered hop test campaign, scheduled to begin as early as the end of May.
On the orbital Starship side of things, Boca Chica took a major symbolic step towards aeroshell completion by capping off the upper half of the prototype with a stainless steel nose section. Altogether, the Starship assembly now stands about 25m (80 ft) tall from tip to tail, roughly 60% as tall as a Falcon 9 booster (first stage). With the installation of the craft’s nose, SpaceX has also implicitly confirmed that most – if not all – of the Starship prototype’s tankage still needs to be built, unless a great deal of hardware is hiding inside Boca Chica’s on-site tent.
What could either be the orbital Starship’s seven-Raptor engine section or the start of its liquid oxygen or methane tank is also being built a few hundred feet distant. That mystery segment was recently lifted onto a second concrete jig for easier access, while SpaceX has also been hard at work building a dedicated integration facility similar to the warehouse being used in Florida.
Altogether, SpaceX’s South Texas team appears to be 30-40% away from completing a Starship-sized steel aeroshell. A huge amount of work remains to be done on the inside of the theoretically orbit-capable vehicle, including propellant tanks, a thrust structure capable of supporting seven Raptor engines, landing legs/fins, and a jungle of plumbing and avionics installation. Still, the amount of progress already visible is undeniably impressive, made even more intriguing by the existence of a separate Starship build effort to the east.

Tesla’s golden era is no longer a tagline
Tesla “golden era” teaser video highlights the future of transportation and why car ownership itself may be the next thing to change.
The golden age of autonomous ridesharing is arriving, and Tesla is making sure we can all picture a future that looks like the future. A recent teaser posted to X shows a Cybercab parked outside a home, and with a clear message that your everyday life may soon look like this when the driverless vehicles shows up at your door.
Tesla has begun the rollout of its Robotaxi service across US cities, and the production of its dedicated, fully-autonomous Cybercab vehicle. The first Cybercab rolled off the Giga Texas assembly line on February 17, 2026, with volume production now targeted for this month. Additionally, the Robotaxi service built around it is already running, without human drivers, in US cities.
Tesla Cybercab production ignites with 60 units spotted at Giga Texas
The Cybercab is built without a steering wheel, pedals, or side mirrors, designed from the ground up for unsupervised autonomous operation. Musk described the manufacturing approach as closer to consumer electronics than traditional car production, targeting a cycle time of one unit every ten seconds at full scale.
Drone footage from April 13, 2026 captured over 50 Cybercab units on the Giga Texas campus, with several clustered near the crash testing facility. Musk has noted that Tesla plans to sell the Cybercab to consumers for under $30,000, and owners will be able to add their vehicles to the Tesla robotaxi network when not in personal use, potentially generating income to offset the vehicle’s purchase cost. That model changes the math on vehicle ownership in a meaningful way, making a car something closer to a depreciating asset that can also earn by paying itself off and generate a profit.
During Tesla’s Q4 earnings call, the company confirmed plans to expand the Robotaxi program to seven new cities in the first half of 2026, including Dallas, Houston, Phoenix, Miami, Orlando, Tampa, and Las Vegas. The service already runs without safety drivers in Austin, and public road testing of the Cybercab has expanded to five states, including California, Texas, New York, Illinois, and Massachusetts.

Tesla’s last chance version of the flagship Model X is officially gone
The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Tesla enabled a last-chance version of its two flagship vehicles, the Model S and Model X, over the past few weeks. The Model X, the company’s original SUV, is officially gone.
Tesla has officially closed the book on its most exclusive send-off for the Model X. The limited-run Model X Signature Edition—priced at $159,420 before fees and limited to just 100 units—is now sold out, with reservations closed as of April 16.

The Signature Edition was no ordinary Model X Plaid. Offered exclusively by invitation to select existing Tesla owners, it represented the final production batch of the current-generation Model X before manufacturing at Fremont ends.
Every unit featured an exclusive Garnet Red exterior paint, unique badging, and a standard six-seat configuration. With full Plaid powertrain specs—Tri-Motor All-Wheel Drive, over 1,000 horsepower, and blistering acceleration—it was positioned as a collector’s item for loyalists who wanted one last shot at owning a piece of Tesla history.
The timing is no coincidence.
Tesla announced earlier this year that it would discontinue regular production of both the Model S and Model X to repurpose the Fremont factory’s dedicated lines for mass production of its Optimus humanoid robots.
Elon Musk has repeatedly emphasized that Optimus could ultimately become more valuable to the company than its vehicle business, with ambitions to build hundreds of thousands of units annually.
The Signature Editions served as a final “runout” series: 250 for the Model S and only 100 for the Model X, all built to the highest Plaid specification before the line is converted.
Deliveries of the remaining Signature units are scheduled to begin in May 2026. For buyers who secured one, it’s the ultimate swan song for a vehicle that helped define Tesla’s early luxury EV dominance.
Launched in 2015, the Model X introduced falcon-wing doors, a panoramic windshield, and class-leading performance that turned heads and set benchmarks. While newer models like the Cybertruck and refreshed Model Y have taken center stage, the Model X Plaid remained a halo product for those seeking maximum range, space, and speed in an SUV package.
With inventory of standard Model X units already nearly exhausted across the U.S., the rapid sell-out of the Signature Edition underscores enduring demand for Tesla’s premium flagships even as the company pivots toward robotics and autonomy.
For enthusiasts, these 100 garnet-red SUVs will likely become instant collector’s items—tangible reminders of the vehicles that built the brand before Tesla’s next chapter fully begins. The last chance is gone, but the legacy endures.

Tesla Optimus V3 hand and arm details revealed in new patents
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
Tesla is planning to soon reveal its latest and greatest version of the Optimus humanoid robot, and a series of new patents for the hands and arms, with the former being, admittedly, one of the most challenging parts of developing the project.
Two new patents, which were coincidentally filed on the same day as the “We, Robot” event back in October 2024, protect Tesla’s mechanically actuated, tendon-driven architecture.
The designs relocate heavy actuators to the forearm, route cables through a sophisticated wrist design, and employ innovative joint assemblies to achieve human-like dexterity while enabling lightweight construction and high-volume manufacturing.
Core Tendon-Driven Hand Architecture
The primary patent, which is titled “Mechanically Actuated Robotic Hand,” details a cable/tendon-driven system.
Actuators are positioned in the forearm rather than the hand. Each finger features four degrees of freedom (DoF), while the wrist adds two more.
Tesla’s Optimus V3 robot hand looks to have been revealed in a new international patent published today.
The patent describes a tendon/cable-driven hand:
• Actuators in the forearm
• Each finger has 4 degrees of freedom
• The wrist has 2 degrees of freedom
• Tendon-driven… pic.twitter.com/eE8xLEYSrx— Sawyer Merritt (@SawyerMerritt) April 16, 2026
Three thin, flexible control cables (tendons) per finger extend from the forearm actuators, pass through the wrist, and connect to the finger segments. Integrated channels within the finger phalanges guide these cables selectively—routing behind some joints and forward of others—to enable independent bending without unintended motion.
Patent diagrams illustrate thick cable bundles emerging from the wrist into the palm and fingers, with labeled pivots and routing guides. This setup closely mirrors human forearm-muscle and tendon anatomy, where most hand control originates proximally.
Advanced Wrist Routing Innovation
One of the standout features is the wrist’s cable transition mechanism. Cables shift from a lateral stack on the forearm side to a vertical stack on the hand side through a specialized transition zone.
Boom! @Tesla_Optimus 의 3세대 구조로 추정되는, 로봇 팔 및 관절에 대한 특허가 공개되었습니다.
아티클 작업에 들어가겠습니다.
1년 넘게 기다려 온, 정말 귀한 특허인데, 조회수 100만대로 터져줬으면 좋겠네요. 😉@herbertong @SawyerMerritt@GoingBallistic5 @TheHumanoidHub pic.twitter.com/CCEiIlMFSX

This geometry significantly reduces cable stretch, torque, friction, and crosstalk during combined yaw and pitch wrist movements — common failure points in simpler tendon systems that cause imprecise or jerky motion.
By minimizing these issues, the design supports smoother, more reliable multi-axis wrist operation, essential for complex real-world tasks.
Companion Patents on Appendage and Joint Design
Two supporting patents provide additional depth. “Robotic Appendage” covers the overall forearm-to-palm-to-finger assembly, with a palm body movably coupled to the forearm and finger phalanges linked by tensile cables returning to forearm actuators. Tensioning these cables repositions the phalanges precisely.
“Joint Assembly for Robotic Appendage” describes curved contact surfaces on mating structures paired with a composite flexible member. This allows smooth pivoting while maintaining consistent tension, enhancing durability, and simplifying assembly for mass production.
Executive Insights on Hand Development Challenges
Tesla executives have consistently described the hand as the most difficult component of Optimus.
Elon Musk has called it “the majority of the engineering difficulty of the entire robot,” emphasizing that human hands possess roughly 27–28 DoF with an intricate tendon network powered largely by forearm muscles. He has likened the challenge to something “harder than Cybertruck or Model X… somewhere between Model X and Starship.”
In mid-2025, Musk acknowledged that Tesla was “struggling” to finalize the hand and forearm design. By early 2026, he stated that the company had overcome the “hardest” problems, including human-level manual dexterity, real-world AI integration, and volume production scalability.
He estimated the electromechanical hand represents about 60 percent of the overall Optimus challenge, compounded by the lack of an existing supply chain for such precision components.
These patents directly tackle the acknowledged pain points: relocating actuators reduces hand mass and inertia for better speed and efficiency; advanced wrist routing and joint geometry address friction and crosstalk; and simplified, stackable parts visible in the diagrams indicate readiness for high-volume manufacturing.
Implications for Optimus Production and Leadership
Collectively, the patents portray the Optimus v3 hand not as a mere prototype, but as a production-oriented system engineered from first principles.
The 22-DoF architecture, forearm-driven tendons, and crosstalk-minimizing wrist deliver a clear competitive edge in dexterity. They align with Musk’s view that high-volume manufacturing is one of the three critical elements missing from most other humanoid projects.
For Optimus to become the most capable humanoid robot, its hand needed to replicate the useful and applicable design of the human counterpart.
These filings demonstrate that Tesla has transformed years of engineering challenges into patented, elegant solutions — positioning the company strongly in the race toward general-purpose robotics.
