SpaceX’s Crew Dragon preps for debut as race to return astronauts to US craft nears final stages
After spending two weeks testing in a specialized NASA-run facility, SpaceX’s first flightworthy Crew Dragon spacecraft was shipped from Ohio to Florida, where it will now spend a number of months preparing for its first (uncrewed) launch into Earth orbit.
Known as Demonstration Mission 1 (DM-1), this critical milestone must be passed before the capsule will be certified to carry NASA astronauts to the International Space Station (ISS) sometime in 2019. While DM-1 will not sport a human crew, the spacecraft is nevertheless expected to demonstrate all life and mission-critical components, ranging from Crew Dragon’s complex array of avionics and ground/orbital communications equipment to craft’s ability to safely return passengers to Earth with a soft ocean landing.
SpaceX’s Crew Dragon spacecraft has been in the serious hardware development phase for approximately five years, although the concept itself dates back about as early as its Cargo Dragon predecessor – 2005 to 2006, publicly. Over the course of roughly two weeks of testing at NASA’s Plum Brook Station, Crew Dragon was likely subjected to a suite of environmental conditions the spacecraft will need to routinely survive to make it through initial launch and successfully operate under the rigors of microgravity and thermal vacuum conditions.

Given the DM-1 capsule and trunk’s fairly quick jaunt at the huge Plum Brook vacuum chamber and equally quick arrival in Florida, those test results were likely quite favorable. Still, a major amount of work lies ahead before the first full Crew Dragon is ready for its launch atop Falcon 9. Most significantly, the craft’s trunk did not follow its fellow capsule to Florida, but rather returned to SpaceX’s Hawthorne, CA factory to be outfitted with critical flight hardware, particularly radiators and solar arrays. Once that outfit is complete, the module will also be shipped to Florida before being integrated with the DM-1 Crew Dragon capsule.
Of note, the DM-1 capsule has been constructed from the start to support a plan to use the vehicle in an in-flight abort test meant to ensure that the craft can wrest its passengers from harm’s way even at the most intense point of launch, where aerodynamic pressures are at their peak. In order to properly support both the DM-1 orbital mission and the in-flight abort test to follow, the capsule has been outfitted with a fair amount (hundreds of pounds) of hardware that will be unique to the pathfinder spacecraft. This understandably adds its own complexity to the already intense program’s first orbital mission, although it will hopefully not translate into additional delays.

SpaceX competitor’s crewed spacecraft and rocket take shape
It’s worth noting that SpaceX is effectively operating at a distinct – albeit partially self-wrought – financial handicap when compared with Boeing’s Starliner spacecraft program, one of two vehicles funded by NASA to accomplish the same task of safely and reliably transporting astronauts to and from the ISS.
“NASA awarded firm-fixed-price contracts in 2014 to Boeing and Space Exploration Technologies Corporation (SpaceX) [of] up to $4.2 billion [for Boeing] and $2.6 billion [for SpaceX] for the development of crew transportation systems.” (GAO-18-476)

In other words, Boeing requested and received a full 60% more than SpaceX to – quite literally – accomplish an identical task. Alongside the storied and brutally expensive history of crewed American spaceflight, both contracts are an absolute steal for two modernized, crew-capable spacecraft, but a 60% premium is a 60% premium. Foreseeable but slight cost overruns caused, among other things, by additional contractual requirements from NASA have followed a similar trend, roughly proportional to each company’s slice of the original $6.8b Commercial Crew contract.
“As of April 2018, NASA requirement changes had increased the value of contract line item 001 for Boeing by approximately $191 million and for SpaceX by approximately $91 million.” (GAO-18-476)
Still, Boeing’s progress towards its own DM-1 and DM-2 demo flights and a pad-abort test are impressive, although it very likely is more of a demonstration of a different approach to public communications than of any actual step up on SpaceX. In the last few weeks, Boeing has released a number of photos showing off the progress made building its own Starliner capsules and service modules (trunks), three of which are currently in varied states of assembly and integration in the company’s Florida-based facility. Additionally, United Launch Alliance CEO Tory Bruno has shared off-and-on updates and photos of the launch contractor’s own progress assembling the rockets that will launch Boeing’s spacecraft.

Regardless, a huge amount of work lies ahead before both Boeing and SpaceX’s crewed spacecraft are able to conduct their first uncrewed and crewed launches into orbit. Now very outdated, NASA has stated several times recently that the presently available targets of NET August 31 will likely be updated later this month, pushing DM-1 debuts into NET Q4 2018 and the first commercial crewed demo missions to 2019.
Stay tuned, as the Block 5 Falcon 9 tasked with launching SpaceX’s own DM-1 Crew Dragon will likely be the next of a recent flood of finished rockets to leave the company’s Hawthorne factory, where it will head to McGregor, Texas to complete acceptance wet dress rehearsals and static fire tests before shipping to SpaceX’s Pad 39A in Florida.

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.
