Firefly Aerospace’s Alpha rocket has successfully reached orbit on its second try, cementing the company as the victor of a mostly unintentional race between three American NewSpace startups.

After weeks of delays and three aborted launch attempts on September 11th, 12th, and 30th, the second carbon-fiber Alpha rocket lifted off from its Vandenberg Space Force Base (VSFB) SLC-2W launch pad at 12:01 am PDT (07:01 UTC) on October 1st. According to Firefly, the resulting mission was a “100%…success”, indicating that it achieved all of the company’s objectives – an outcome far from guaranteed on the second flight of any orbital rocket.

In a familiar display, Alpha’s suborbital booster lifted the upper stage, fairing, and payload most of the way out of the Earth’s atmosphere within a few minutes. After a mechanical system pushed the two stages apart, the upper stage successfully ignited its lone Lightning engine, ejected the two-piece fairing (nose cone) protecting its payloads, and continued uphill for another five minutes before reaching a stable parking orbit around 250 kilometers (~160 mi) above Earth’s surface.

After successfully reaching orbit, Alpha’s upper stage even made it through a more than 90-minute coast phase and reignited for a brief second burn. Finally, Alpha managed to deploy all seven of the satellites it lifted off with. As a test flight, there was no guarantee that those payloads would end up anywhere other than the Pacific Ocean, so the successful deployment was likely a very pleasant surprise for all satellite operators involved in the mission.

Nicknamed “Into The Black” by Firefly, it was the company’s second Alpha flight and followed an unsuccessful attempt on September 3rd, 2021. During the rocket’s first launch, a loose cable caused one of its booster’s four main Reaver engines to fail almost immediately after liftoff, dooming the attempt. However, the rest of the booster fought for more than two minutes to keep the mission on track before a termination system destroyed the rocket, demonstrating otherwise excellent performance and gathering invaluable data and experience.

Firefly wasted no time putting that experience to good use. Compared to the first vehicle, the booster and upper stage for Alpha’s second flight sailed through preflight testing and completed their respective proof tests (a combined wet dress rehearsal and static fire) on their first tries. That smooth processing bodes well for the timing of Firefly’s third Alpha launch, although the company’s official accounts have strangely been almost silent after Flight 2’s success.

Soon after launch, third-party data showed that Alpha deployed its seven payloads into a 210 x 270 kilometer (130 x 170 mi) orbit. Firefly’s official launch page had stated that the target orbit was 300 kilometers (~185 mi) and called the second ignition of the upper stage a “circularization burn.” Given that the final orbit is far from circular and has an apogee a full 10% below that stated target, it wasn’t clear the rocket had performed exactly as expected. The orbit’s very low perigee means that the customer satellites Alpha deployed could reenter Earth’s atmosphere and burn up after a matter of weeks in space, rather than months or years.

But according to Bill Weber, who became CEO of Firefly less than a month before the launch, Alpha “deployed [Firefly’s] customer payloads at exactly the spot [the company] intended,” strongly implying that the strange final orbit was intentional.

Additionally, official footage Firefly released after the launch suggests that Alpha’s upper stage Lightning engine nozzle narrowly missed the booster’s interstage during stage separation. Had the drifting booster hit that nozzle, it would have likely caused the upper stage to begin tumbling and potentially ended the mission well before orbit. Thankfully, it didn’t, and it should be relatively easy to fix whatever caused the Alpha booster to begin slipping sideways so quickly after separation.

Alpha is the largest all-carbon-fiber rocket ever built. It stands 29.5 meters (~95 ft) tall, 1.8 meters (6 ft) wide, weighs 54 tons (~120,000 lb) fully fueled, and can produce up 81 tons of thrust (~180,000 lbf). Alpha can launch up to 1.17 tons ~(2600 lb) of useful cargo to low Earth orbit (LEO), making it the first successful entrant in a new and rapidly growing field of privately-developed rockets designed to launch 1-2 tons to orbit.

Coincidentally, Firefly found itself neck and neck with two other prospective US providers, Relativity Space and ABL Space. For several months, all three companies were aiming to successfully launch their one-ton-class rockets to orbit sometime in the late summer or early fall. But despite delays, Firefly – already more than a year ahead after its first launch attempt in 2021 – still beat Relativity and ABL Space to flight and did so successfully, securing itself a small but significant milestone in the history of private spaceflight.

The timeline for Relativity’s first 3D-printed Terran-1 rocket launch is no longer clear after a hurricane disrupted its preflight test campaign. ABL Space, meanwhile, has been forced to sit with its first RS1 rocket ready to launch for weeks while waiting on the FAA to complete paperwork and grant it a launch license. Had the FAA moved faster, it’s entirely possible that ABL Space could have launched before Firefly’s Alpha Flight 2, although the odds of success are much lower for RS1 during its debut. Pending that regulatory approval, ABL Space intends to launch RS1 out of Kodiak, Alaska as early as mid-October.

Firefly has yet to offer a substantial statement after the successful launch, which means that the company has provided no information about its next steps or next launch. Per prior statements, the company is working to upgrade its Texas factory to enable up to six Alpha launches in 2023.

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.

Published

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.

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.

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.”

Elon Musk shares ridiculous fact about Optimus’ hand demos

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.
