SpaceX ramps Starship hiring as Elon Musk talks Texas rocket factory's "awesome" progress
After several successful tests last month, Elon Musk says that SpaceX’s South Texas Starship team is looking to rapidly expand in order to aggressively ramp up Starship manufacturing in a sign that the nascent rocket factory is making excellent progress.
Almost immediately after SpaceX successfully wrapped up its first and second explosive Starship tank tests last month, the company’s Boca Chica, Texas presence started to take on a new atmosphere, reminiscent of the rapid progress made at a since-mothballed Florida Starship facility. Perhaps thanks to the fact that SpaceX’s Boca Chica Starship facilities are adjacent to a dedicated test and launch facility just a mile down the road, it’s looking much less likely that a similar fate will befall its Texas presence.
Instead, SpaceX’s successful Starship tank tests – intentionally destroying two massive propellant tanks – are a testament to the progress the next-generation rocket is making in Texas. In fact, SpaceX CEO Elon Musk has effectively stated that after the most recent tank test, the company is now ready to shift gears and start building the first space-bound Starship prototypes, while the last week or two of SpaceX’s visible Texas activities make it clear that that shift is already well underway.
In simple terms, SpaceX now appears to be moving full speed ahead in a bid to manufacture, assemble, and test the first flightworthy, full-scale Starship prototypes. It’s worth noting that CEO Elon Musk has underestimated the challenge at hand several times in the last 18 or so months of Starship development, frequently suggesting that the first full-scale prototype of the spacecraft would be ready for a challenging flight test and maybe even its first orbital flights as early as 2019.
For a number of reasons, those ambitious targets were not met. To Musk’s credit, the executive is at least conscious of his tendency to be wildly optimistic when it comes to schedules and has effectively tacked on an asterisk that the schedules and deadlines he often publicizes tend more along the lines of “this time-frame is technically possible without breaking the laws of physics” than anything verging on pragmatism. With challenges as complex as those faced in spaceflight, let alone massive, fully-reusable rockets like Starship, it’s hard to be surprised that practical deadlines tend to be miles away from theoretically-possible minimums.
As such, it wouldn’t be unreasonable to feel a bit like the townspeople with a boy crying wolf, but there are arguably several reasons for optimism, this time around. Most importantly, as partially pictured above, SpaceX has completed four intentionally destructive tests with full-scale Starship hardware in just the last 2.5 months. Deemed unfit for flight, SpaceX pressurized Starship Mk1 with liquid nitrogen until it burst in November 2019, reaching an estimated 3-5 bar (45-75 psi).
SpaceX spent the following month upgrading both the methods and facilities used to build Starship prototypes in South Texas – a process that is still very much ongoing. However, two recent tests of Starship tanks built with some of those new methods and facilities have unequivocally proven that great progress is being made. The first ‘test tank’ managed 7.1 bar (105 psi) before it burst, while a second tank completed less than three weeks later reached 7.5 bar (110 psi) with water and 8.5 bar (125 psi) with liquid nitrogen on January 28th. Between those tests, Musk revealed that 6 bar was the bare minimum necessary for orbital Starship flights, while 8.5 bar would potentially offer the safety margins needed for crewed Starship flights.
In other words, SpaceX’s last two tank tests have effectively proved that – even with facilities and methods only partially upgraded – the company is ready to begin manufacturing the first truly flight-rated Starship prototypes. In response, Musk recently stated that he was going “max hardcore on” Starship design and production in Boca Chica and revealed that SpaceX would host a second South Texas jobs fair in three weeks to help rapidly staff its growing rocket factory.
Looking at the progress SpaceX has made in just the last week, it’s hard to fault Musk’s brimming enthusiasm. Now breaking in new semi-automated welding machines, upgraded production equipment, and two massive sprung structures (i.e. tents), SpaceX engineers and technicians are churning out improved steel rings, tank domes (bulkheads), smaller propellant tanks, and more at a breakneck pace relative to the last year of Starship work. Additionally, at least six of those new rings have been stacked together in two sections, likely representing the effective birth of the first flightworthy Starship – ‘SN01’.
With SpaceX’s new enclosed facilities, much of its South Texas work is now hidden. Still, from what’s visible, it’s safe to say that the company is well its way to completing the first flight – and possibly orbit – worthy Starship prototypes in the near future.

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.

Tesla intertwines FSD with in-house Insurance for attractive incentive
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla intertwined its Full Self-Driving (Supervised) suite with its in-house Insurance initiative in an effort to offer an attractive incentive to drivers.
Tesla announced that its new Safety Score 3.0 will automatically have a perfect score of 100 with every mile driven with Full Self-Driving (Supervised) enabled.
The change is designed to boost customers’ average safety scores and deliver noticeably lower monthly premiums.
The move marks the clearest link yet between Tesla’s autonomous driving technology and its proprietary insurance product. Tesla Insurance already relies on real-time vehicle data—such as acceleration, braking, following distance, and speed—to calculate a Safety Score between 0 and 100. Higher scores have long translated into cheaper rates.
Under the previous system, however, even brief manual interventions could drag down the average, frustrating owners who rely heavily on FSD. Version 3.0 eliminates that penalty for supervised autonomous miles, effectively treating FSD-driven segments as the safest possible driving behavior.
The incentive is immediate and financial. Drivers who keep FSD engaged for the majority of their trips will see their overall score rise, potentially shaving hundreds of dollars off annual premiums.
Tesla framed the update as a direct response to customer feedback, many of whom had complained that the old scoring model punished the very behavior it was meant to encourage.
For now, the program applies only to new policies in six states: Indiana, Tennessee, Texas, Arizona, Virginia, and Illinois.
Existing policyholders are not yet included, a point that drew swift questions from the Tesla community. Many owners in other states, including California and Georgia, expressed hope that the benefit would expand nationwide soon.
The announcement arrives as Tesla continues to roll out FSD Supervised updates and push for regulatory approval of more advanced autonomy. By tying insurance savings directly to FSD usage, the company is putting its own actuarial weight behind the technology’s safety claims.
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla has not disclosed exact premium reductions or the full rollout timeline beyond the six launch states.
Still, the message is clear: the more drivers trust FSD Supervised, the more Tesla Insurance will reward them. In an era when legacy insurers remain cautious about autonomous tech, Tesla is betting that its own data will prove the safest miles are the ones driven hands-free.
