NASA head hints that reusable rocket cos. like SpaceX will enable Moon return
In a series of thoroughly unexpected and impassioned introductory remarks at one of several 2018 Advisory Council meetings, NASA administrator Jim Bridenstine bucked at least two decades of norms by all but explicitly stating that reusable rockets built by innovative private companies like SpaceX and Blue Origin will enable the true future of space exploration.
Incredibly, over the course his fascinating hour-long prelude, Bridenstine effectively mentioned NASA’s own SLS rocket and Orion spacecraft – under development for the last decade at a cost of at least several tens of billions of dollars – a total of one time each. Instead, heavily emphasizing the absolute necessity that NASA’s next major human exploration project be sustainable, the administrator spoke at length about the foundational roles that international and domestic space agencies and private companies will need to take on in order to make NASA’s on-paper return to the Moon both real, successful, and useful.
Aside from his arguably brave (but spot-on) decision to all but ignore Boeing and Northrop Grumman’s SLS rocket and Lockheed Martin’s Orion spacecraft over the course of an hour spent speaking about the future of NASA’s human exploration of the Moon and on spaceflight more generally, Bridenstine had nothing but praise for recent successes in the American aerospace industry.
Most notably, he spoke about his belief – at least partially stemming from an executive order requiring it – that the only way NASA can seriously succeed and continue to lead the world in the task of human space exploration is to put an extreme focus on sustainability. Judging from his comments on the matter, the new NASA/Federal buzzword of choice is just a different way to describe hardware reusability, although it certainly leaves wiggle room for more than simply avoiding expendable rocket hardware.
“It’s on me to figure out how to [return to the Moon] sustainably. … And this time, when we go, we’re gonna go to stay. So how do we do go sustainably? Well, [we take] advantage of capabilities that didn’t exist in this country even five or ten years ago. We have commercial companies that can do things that weren’t possible even just a few years ago … to help develop this sustainable [Moon exploration] architecture.” – NASA Administrator Jim Bridenstine, 08/29/2018
While it might not look like much (aside from a “no duh” statement) to anyone unfamiliar with the trials and tribulations of NASA bureaucracy and politicking, this quote – directed at an audience of senior NASA scientists and managers and independent experts – is absolutely extraordinary in the context of NASA’s history and the formulaic eggshells NASA administrators have traditionally been forced to walk on when discussing American rocketry.
Not only is SLS/Orion utterly and conspicuously absent in a response to the “how” of starting a new wave of lunar exploration, but Bridenstine also almost explicitly names Blue Origin and SpaceX as torchbearers of the sort of exceptional technological innovation that might revolutionize humanity’s relationship with space. By referring specifically to “commercial companies that can do things that weren’t possible even just a few years ago”, the only obvious answers in the context of serious human exploration on and around the Moon are Blue Origin and SpaceX, both of which managed their first commercial rocket landings in late 2015.
Bridenstine went even further still, noting that NASA will need not just reusable rockets for this sustainable lunar exploration, but also reusable orbital tugboats (space tugs) to sustainably ferry both humans and cargo to and from Earth and the Moon and reusable lunar landers capable of many trips back and forth from space stations orbiting the moon. At one point, he even used SpaceX CEO Elon Musk’s (in)famous and well-worn analogy of commercial airlines to emphasize the insanity of not using reusable rockets:
“We have reusable rockets [now]… Imagine if you flew here across the country to [NASA Ames] in a 737 and when the mission was over, you threw the airplane away. How many of you would have flown here?” – NASA Administrator Jim Bridenstine, 08/29/2018
At today's NASA Advisory Council (NAC) meeting, Administrator Jim Bridenstine says the next hop to the moon is going to be sustainable – and will require reusable spaceflight hardware. Uses the same airplane analogy @ElonMusk does when it comes to explaining advantages.

Reusable rockets lead the charge
It may be generous to include Blue Origin side by side with SpaceX, given the fact that its New Shepard rocket is extremely small and very suborbital, but the company does have eyes specifically set lunar landers and outposts (a project called Blue Moon) and is developing a large and reusable orbital-class rocket (New Glenn) set to debut in the early 2020s.

- Falcon Heavy’s side boosters seconds away from near-simultaneous landings at Landing Zones 1 and 2. (SpaceX)
-
- We’re not here just yet, but SpaceX is pushing hard to build BFR and get humanity to Mars as quickly as practicable. (SpaceX)
-
- Blue Origin’s aspirational future, the highly reusable BE-4 powered New Glenn rocket. (Blue Origin)
-
- Blue Origin’s Blue Moon concept, set to begin experimental lunar landings as early as 2022 or 2023. (Blue Origin)
SpaceX, while focused on Mars colonization, has also expressed a willingness to participate in any sort of lunar exploration that NASA or other international space agencies might have interest in. Currently in the middle of developing its own massive and fully reusable rocket, known as the Big F_____ Rocket (BFR), SpaceX nevertheless already has a flight-tested, highly successfully, and unbeatably cost-effective family of reusable Falcon rockets capable of affordably launching significant mass to the Moon. In fact, both NASA and ESA (European Space Agency) are already seriously considering SpaceX’s Falcon Heavy as the launch vehicle of choice for several critical pieces of a Moon-orbiting space station, expected to launch no earlier than the early to mid-2020s.
Whether or not Bridenstine’s incredible and eloquent statements translate into tangible changes to NASA’s long-term strategy, it’s quite simply refreshing to hear a senior NASA executive – let alone the administrator – speak freely and rationally about the reality of what is needed to enable a truly new era of human spaceflight and exploration.

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.
