SpaceX to fly reused rockets on half of all 2018 launches as competition lags far behind

Published

on

Speaking at SATELLITE 2018, SpaceX President Gwynne Shotwell reiterated the company’s commitment to and their customers’ acceptance of reusable rockets at the 2018, stating that SpaceX intends to fly reused boosters on at least half of their 2018 launch manifest.

Barring unforeseen circumstances, SpaceX is effectively on track to complete 30 separate missions this year with more than half flying flight-proven Falcon 9 (and Heavy) boosters. Thus far, the company has completed five launches – three flight-proven – in two months, perfectly extrapolating out to ~18 flight-proven missions and 30 total launches in 2018. While the middle weeks of March will not see any SpaceX launches, the company is on track to reach 11 flights total in late April/early March, six with reused boosters.

Ignoring the tidal wave of reusable rockets

Ultimately, SpaceX’s scheduled launch cadence lends a huge amount of credence to Shotwell’s historically pragmatic claim. Assuming a successful introduction of Falcon 9 Block 5 sometime in April (currently April 5), SpaceX may even be able to get closer to flying reused boosters on two thirds of their 2018 launches, a truly jaw-dropping achievement for a year-old technology in an industry that previously saw minimal technological progress in rocketry for the better part of two decades, if not three or even four.

In almost every conceivable manner, SpaceX has taken a complacent industry by surprise, to such an extent that other major rocket builders have barely begun to develop their competitive responses to successful reuse. SpaceX’s main domestic and global competitors – ULA, Arianespace, and ILS – are at best five years away from more than dabbling in operationally reusable rocketry. ULA is in the best shape here, and their strategy of recovering just the engine segment of their future Vulcan rocket is unlikely to fly – let alone conduct the first real reuse of engines – before 2023 or 2024 at the absolute earliest, and reuse is by no means a public priority for the company.

At this point in time, Arianespace has been halfhearted for years in their attempts to seriously consider reusable rocketry. As of 2018, the closest they have gotten is a noncommittal study that would see the French and German space agencies field a Falcon 1-sized (tiny) vehicle to study the SpaceX approach to landing rockets. In the case of Arianespace, ULA, and ILS, their Ariane 6, Vulcan, and Proton Medium rockets currently under development for inaugural launches no earlier than 2020 have indeed all been explicitly designed to compete with SpaceX’s highly-competitive Falcon 9. Sounds promising, right? The reality, however, is that each distinct company has more or less designed their modernized rockets to compete with Falcon 9’s pre-reusability pricing. Even before SpaceX begins to seriously lower the cost of reused Falcon 9s at the customer level, their competitors are already incapable of beating the price of Falcon 9 and Falcon Heavy, at least without accepting net losses or leaning on government subsidies.

Arianespace’s Ariane 5 and ULA’s Atlas 5 and Delta 4 rockets do have impeccable and undeniably superior records of reliability, but SpaceX is making rapid progress towards enhanced reliability and unprecedented launch cadences. Falcon 9 Block 5 – SpaceX’s hard-won solution to rapid and cheaply reusable rocket boosters – is weeks away from its first launch, with something like six or more additional Block 5 boosters in the late stages of construction and assembly at SpaceX’s Hawthorne factory. The first prototype of BFR, a rocket designed with a fully-reusable booster and upper stage, has already begun to be assembled, with spaceship test hops scheduled to begin in 2019 and full-up orbital tests hoped to begin as early as 2020. Even with a pessimistic outlook on SpaceX’s BFR development prospects, the likelihood of orbital tests/operational launches beginning before the mid-2020s is incredibly high, barring insurmountable technological hurdles.

Whether or not SpaceX actually manages to begin its first flights to Mars in 2022 (even 2024-2026), BFR and its highly reusable orbital upper stage will swallow the launch industry whole if it manages to be even a tenth as affordable as its engineers intend it to be, and it will likely be in the late stages of hardware development and test launches before ULA, Arianespace, or ILS have even begun to operationally fly their tepid responses to reusability.

SpaceX’s BFR is being designed to launch crew, cargo, and fuel for unprecedentedly low prices. (SpaceX)

Tesla patent aims to improve common on-road complaint

Published

Tesla is continuing to push the boundaries of vehicle dynamics, as its latest published patent, US12654505B2, or “Suspension Actuator System for a Vehicle,’ which has finally been pushed through.

The design, which is credited to inventors Brian Lee Doorlag, Avraham Kagan, and Justin Sill, introduces a sophisticated hybrid suspension design that blends active motor-driven control with strategic passive elements to deliver superior ride quality, energy efficiency, and resilience against road imperfections, especially potholes.

At the heart of the system is an active control element powered by an electric motor. This motor drives a belt connected to a ball nut assembly and threaded screw, which adjusts the effective length of the suspension strut in real time.

By extending or retracting, the actuator can lift or lower the wheel more accurately, which can end up countering road disturbances. Sensors, including accelerometers and wheel position monitors, feed data to a suspension control system that processes inputs and commands the motor instantly.

This active component doesn’t work alone. A low-rate air spring mounts in parallel with the actuator. Its primary role is to offset much of the vehicle’s static weight, dramatically reducing the power demand on the motor.

Without this, the active system would constantly fight gravity, draining energy and generating heat. The air spring handles steady-state loads efficiently, allowing the motor to focus on dynamic adjustments.

Complementing this is a series of passive control elementsa spring and an adaptive damper—placed between the actuator and the wheel. This setup filters high-frequency vibrations before they reach the active motor, preventing it from overworking on minor inputs. The adaptive damper, potentially magnetorheological or valve-controlled, further tunes damping electronically for optimal comfort and stability.

How It Differs from Traditional Suspensions

Traditional passive suspensions compromise between comfort and handling, while pure active systems can be power-hungry and complex. Tesla’s hybrid approach resolves this by delegating tasks: the parallel air spring manages weight and low-frequency body motions, the series elements absorb rapid vibrations, and the active actuator tackles larger, lower-frequency events.

The result is a smoother, more isolated cabin experience. High-frequency road noise and harshness diminish, while the vehicle maintains precise control during cornering or acceleration. Energy efficiency improves, too—lower motor loads mean reduced battery drain, potentially extending range in electric vehicles.

How It Mitigates Potholes Specifically

Potholes are a major challenge because they provide a sudden drop to the wheel plunge, jarring the body of the vehicle, risking damage. The patent explicitly addresses this. Upon detecting a pothole (via sensors or predictive mapping), the control system activates

the motor to retract the strut, effectively pulling the wheel upward to minimize downward excursion. The series spring/damper cushions the impact, while the parallel air spring maintains overall support.

This proactive “wheel retraction” prevents sharp jolts, preserving passenger comfort and protecting components. Integrated with Tesla’s road roughness mapping patents, the system could anticipate potholes from fleet data, enabling preemptive adjustments for even smoother navigation.

Future Implications for Tesla Vehicles

This technology builds on Tesla’s existing adaptive dampers and air suspension that is seen in Cybertruck, but advances toward fully active control. It could roll out to future models, including refreshed Cybertrucks or next-gen vehicles, enhancing both daily drivability and off-road capability. By minimizing power use and complexity, it aligns with Tesla’s goals of efficiency and scalability.

In summary, US12654505B2 exemplifies Tesla’s engineering philosophy: intelligent integration over brute force. This hybrid suspension promises quieter, more comfortable rides and robust pothole defense, potentially setting a new standard for automotive comfort. As Tesla iterates, drivers can look forward to roads feeling far less rough.

The Tesla Cybercab got a huge nod of support from a Texas Department of Transportation official, who said the all-electric ride-hailing vehicle is “a tangible example of how quickly our transportation system is evolving.”

The Cybercab was present at the Texas Department of Transportation’s Texas Innovation Invitational, an event held each year that allows innovative companies to showcase advancements in transportation.

Tesla Cybercab specs revealed: range, curb weight, range ratings, and more

Marc Williams, the Texas Department of Transportation’s Executive Director, sat in a Cybercab and shared his thoughts in an extensive post on LinkedIn.

Williams’s comments show how Tesla, with its Cybercab, is leading the charge of passenger travel and how it’s changing so rapidly. He notes the absence of traditional driving controls as a telltale sign that the Cybercab is a catalyst for major automotive change, taking controls from drivers and turning them into full-time passengers.

“Observing this vehicle firsthand–from its design and butterfly doors to the cargo trunk configuration–provides a tangible example of how quickly our transportation system is evolving. Sitting inside the cabin, the complete absence of traditional driver controls underscores a significant shift in mobility and vehicle design. No steering wheel, no accelerator, no brake. Only a single touchscreen monitor.”

Tesla has had a great relationship with the State of Texas, especially with its Robotaxi ambitions. Currently, Texas has Tesla Robotaxi operating in multiple cities: Dallas, Austin, San Antonio, and Houston. The company’s main manufacturing plant is also located just outside Austin, and Tesla moved its headquarters to the state several years ago.

The Cybercab is a purpose-built, fully autonomous, two-passenger Robotaxi vehicle designed specifically for ride-hailing services. Tesla has said for years it would be built without a steering wheel or pedals present, although there is still quite a bit of debate among the community regarding that potential.

Earlier this week, we received official word that the EPA had provided the Cybercab with a Certificate of Conformity, giving Tesla permission to enter the vehicle into the chain of public commerce. It is officially ready for roads.

The big question for Tesla remains: Can it solve self-driving before the steering-wheel-less Cybercab officially enters production?

The Boring Company just doubled its tunneling power in Nashville

The Boring Company’s Prufrock MB2 is commissioned and ready to mine beneath Nashville’s streets.

The Boring Company’s second tunnel boring machine, Prufrock MB2, is officially ready to dig in Nashville. The company confirmed the news on X, posting: “Prufrock-MB2 is ready to mine in Nashville! MB2 commissioning is complete, including the brief 11 rpm rotation shown here. Will MB2 catch up to MB1, who had quite the head start? And Prufrock-MB3 ships in August!”

MB2 arrives with meaningful improvements over its predecessor. Lessons learned from the launch and operation of MB1 have already been applied to MB2 to improve efficiency and prepare the machine for launch.

Traditional tunnel boring machines operate in a stop-and-go cycle, digging roughly five feet, halt, erect precast concrete segments to line the tunnel wall, then resume. That repeated interruption is one of the main reasons conventional tunneling is slow and expensive. Prufrock is designed to install the tunnel liner simultaneously with mining, eliminating the need to stop every five feet. The machine also skips the need for excavated launch pits. Prufrock arrives on a truck, tilts down, and launches into the ground within 24 hours. And when the tunnel is complete, it emerges from the ground and drives to its next launch site on a trailer, eliminating the need for expensive cranes or pit excavation. The machine is also fully electric and runs with zero people in the tunnel during normal operations, controlled remotely from a surface operations center.

It won’t be long before we hear of another major update on The Boring Company’s Music City Loop project – a planned underground transit network beneath Nashville that would move passengers in electric vehicles through a series of tunnels at highway speeds, and bypassing surface traffic entirely. Nashville was selected in part because of its strong rock conditions that suits the Prufrock machines well, and relatively less regulatory hurdles.

Progress has been steady on multiple fronts. All 37 permits and approvals required ahead of tunneling have been obtained, out of 45 total. Key wins include a fully executed TDOT tunnel permit authorizing 25 miles of tunnel, unanimous airport authority approval for a Nashville International Airport station, and the city’s first residential station agreement serving downtown tower residents.

With MB1 already tunneling, MB2 now commissioned, and MB3 shipping in August, Nashville is becoming something of a live proving ground for scaled tunnel boring. The broader ambition is not limited to one city. The Boring Company’s stated goal is to make underground transportation a practical alternative to surface roads across major metro areas. Nashville is one of many cities, including a successful Las Vegas tunnel system, where that idea is being put to the test at real speed.
