DeepSpace: Virgin Galactic and Blue Origin banter about the fine print of suborbital tourism
Welcome to the sixth edition of our new newsletter, DeepSpace! Each Tuesday, I’ll be taking a deep-dive into the most exciting developments in commercial space, from satellites and rockets to everything in between.

Just shy of two months into 2019, the new year has been marked by a distinct focus on human spaceflight. Most of that focus has centered (as it should) on the relatively imminent launch debut of both SpaceX’s Crew Dragon and Boeing’s Starliner, crewed spacecraft designed and built to carry astronauts into orbit for NASA.
However, beyond SpaceX and Boeing, a considerable amount of noise is being made about the labors and relative progress of companies like Blue Origin and Virgin Galactic, both primarily focused on building a suborbital tourism market with their New Shepard and SpaceShipTwo launch vehicles. Coming as no surprise from companies aiming to create a sustainable market for a very expensive consumer product, both products have been dragged through a torturous maze of marketing hype in a process that has not really done the serious endeavor of human spaceflight any favors.
The Shepard and the Ship
- Virgin Galactic’s launch vehicle provider The Spaceship Company has been working to develop a suborbital platform to launch humans since the early 2000s, incorporated after billionaire Paul Allen funded a group of companies that ultimately won the Ansari X Prize in 2004.
- The Virgin/TSC approach involves a carrier aircraft (Known as White Knight Two) and a much smaller rocket plane (SpaceShipTwo) that is carried up to ~30,000 feet (9 km) before dropping and igniting its engine.
- SpaceShipTwo is meant to reach a maximum altitude of around 300,000 feet (~90 km) at a top speed of roughly Mach 3 (1000 m/s, 2200 mph) before gliding back to land on the same runway.
- In 2014, a combination of bad aeronautical design and pilot error triggered the in-flight failure of the first SpaceShipTwo, killing one of its two pilots. A member of the NTSB board that investigated the failure stated that Scale Composites (one of TSC’s parent companies) “put all their eggs in the basket of the pilots [flying the vehicle] correctly.”
- In a February 2019 video, Virgin Galactic CEO George Whitesides noted that “many aircraft are moving to being less piloted over time [but] our vehicle really is piloted to space.”
- SpaceShipTwo most recently launched on February 22nd.
- Blue Origin has yet to launch an actual human on New Shepard, a small, reusable single-stage rocket designed to loft a separate passenger capsule to approximately 100 km (330,000 ft).
- New Shepard has conducted ten launches since its 2015 debut, most of which saw the crew capsule and booster approximately reach that nominal 100 km apogee and nine of which concluded with a successful landing of the rocket’s booster.
- Capable of carrying up to six passengers, the Crew Capsule features a built-in abort motor that has been successfully tested, as well as a parachute system for a relatively soft landing at end-of-mission.
“Spacecraft” and “astronauts”
- Aside from the generally impressive technology itself and the undeniable challenges and risks of launch humans on fueled rockets, both Blue Origin’s New Shepard and Virgin Galactic’s SpaceShipTwo exist – albeit with different weights – to cater to a new market, suborbital or “space” tourism.
- While NASA is taking advantage of the opportunities to test small experiments with both vehicles as a partial platform, the real goal of both vehicles is to routinely launch paying customers.
- While Blue Origin has yet to announce ticket pricing, Virgin Galactic has priced their offering at $250,000 per person. In both cases, the end result will likely be a six-figure sum in return for an experience that should last no more than 10-60 minutes from start to finish, excluding buildup from screening and whatever training is deemed necessary.
- In other words, short of cases involving charity, tickets on New Shepard and SpaceShipTwo will almost indefinitely be reserved for less than 1% of humanity, those with income around $1M or more per year. This is by no means a bad thing and is, in fact, a proven first or second step in the direction of democratizing exotic or expensive technologies like air travel, computers, and even electric cars (namely Teslas).
- However, both companies are laser-focused on branding their vehicles as spacecraft and their passengers as astronauts, with Virgin Galactic being the worst offender in this regard.
- Aside from literally calling its 600+ prospective customers “Future Astronauts”, Virgin Galactic uses every chance it gets to hammer home its claim that SpaceShipTwo is a commercial spacecraft and its pilots true licensed, “wing”-ed astronauts.
- While passengers are not eligible for official FAA ‘astronauts’ wings’, it appears that Virgin will continue to market its passenger experience as one where customers will get to ‘travel to space’ and more or less become astronauts.
- Blue Origin describes its commercial offering as a “reusable suborbital rocket system designed to take astronauts and research payloads past the Kármán line – the internationally recognized boundary of space.”
- Both Blue and Virgin flights offer about ~4 minutes of weighlessness between launch and landing.

- For context, Alan Shepard – the US test pilot and namesake of New Shepard – was launched to an altitude of almost 190 km (120 mi) for what was recognized as the first US “spaceflight” and spent something like 5-10 minutes in microgravity and above the Karman Line (100 km).
- Used as a rough measure for a sort of fixed, arbitrary boundary between “Earth” and “Space”, reasonable arguments have been made in the last few years that the 100 km Karman Line could more accurately be placed around 70-90 km, in which case Virgin Galactic might actually be technically correct when saying that SpaceShipTwo and its passengers are traveling to space.
- Fewer than 570 humans in all of history have visited space (> 100 km), around 99.5% of which were astronauts that reached orbit. To call pilots of a spaceplane as distinctly suborbital as SpaceShipOne “astronauts” is palatable, particularly given the risks they face as test subjects and test pilots.
- However, to even hinting that tourists riding New Shepard or SpaceShipTwo to altitudes of ~80-100 kilometers are astronauts would do an immense disservice to those that pushed the limits of technology, risked their lives, or even died in pursuit of orbital spaceflight, the only kind of spaceflight with any significant utility.
- Much like cruise ship customers are not under the impression that they are coming along to ‘become sailors’, suborbital tourists are not astronauts. That being said, it’s not inaccurate to describe the experience they will have the privilege of being part of as something truly extraordinary, given that they will become one of a very select few humans to have actually launched on a rocket or seen the exaggerated curvature of Earth’s limb against the blackness of space.
- SpaceX’s first attempted orbital launch of Crew Dragon – a spacecraft designed to transport astronauts to and from the International Space Station – is set to occur as early as 2:49 am EST/07:49 UTC on March 2nd.
- This is the first truly serious date, thanks to the successful completion of a critical pre-launch review conducted by NASA and SpaceX.
- The second launch of Falcon Heavy could occur as early as late March
- Aside from DM-1 and Falcon Heavy Flight 2, it’s unclear what SpaceX mission will happen next, although a West Coast launch (the Radarsat Constellation Mission) is a strong candidate.

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.
