SpaceX’s partial Falcon 9 landing failure could delay next West Coast launch
According to statements made by the Canadian Space Agency (CSA) and media outlet CBC, the launch of the agency’s next-generation Radarsat Constellation Mission (RCM) – a trio of Earth observation satellites weighing >4200 kg (9300 lbs) – has been “postponed … indefinitely” as a consequence of SpaceX’s first failed Falcon 9 booster landing since 2016.
Offering a rare glimpse into some of the extensive planning that goes on behind the scenes to make commercial rocket launches happen, CSA has indicated that the booster it planned to launch on – Falcon 9 B1050 – suffered an untimely (partial) demise during a recovery attempt shortly after successfully launching the CRS-16 Cargo Dragon mission on December 5th, 2018. While the booster shockingly was returned to dry land mostly intact after landing in the Atlantic, SpaceX and CSA must now settle on a different Falcon 9 to launch the mission.

Goldilocks and the Falcon boosters
While it doesn’t look like there are only three possible rocket options for the Radarsat constellation and SpaceX to choose from, the situation of picking a new booster this late in the launch flow is far less simple than it might initially seem. First and foremost, SpaceX likely needs to do its best to accommodate the preferences of customers CSA and MDA (MacDonald, Dettwiler and Associates Ltd.) regardless of how disruptive they may be. Originally targeted for sometime in November 2018, RCM’s launch slipped several months to the second half of February 2019 due to what CSA described as “higher priority missions [for]the US Government and a backlog of launches from…Vandenberg” late last year.
While that alone does not point directly towards any obvious explanations, CBC reporter Dean Beeby’s implication that the mission’s launch is now “postponed…indefinitely” offers a hint of an answer, although it could also be manufactured hyperbole where there actually is none. If CSA actually indicated that the launch is now postponed indefinitely, the only clear explanation for a launch delay greater than a month or so as a result of Falcon 9 B1050’s unplanned unavailability would lie in some unique aspect of that particular Falcon 9 booster.
Although each rocket SpaceX builds can be quite different from each other in terms of general quirks and bugs, the only obvious difference between B1050 and any other flight-proven Falcon 9 booster in SpaceX’s fleet was its low-energy CRS-16 trajectory, something that would have enabled a uniquely gentle reentry and landing shortly after launch. In other words, likely out of heaps of caution and conservatism if it is the case, customers CSA and MDA may have requested (or contractually demanded) that SpaceX launch the Radarsat constellation on a flight-proven Falcon 9 with as little wear and tear as possible, in which case B1050 would have been hard to beat.
“Unfortunately, the landing of [Falcon 9 B1050] was unsuccessful, preventing SpaceX from recuperating the reusable components for the launch of RCM. We continue to work closely with MDA and SpaceX to confirm a launch date for RCM.” – Spokesperson Audrey Barbier, Canadian Space Agency (CSA), 01/15/2019
If the customers remained steadfast in their (speculated) request for a gently-used flight-proven Falcon 9 even after B1050’s partial landing failure, the next most comparable booster would be Falcon 9 B1051 after launching the first orbital Crew Dragon mission sometime no earlier than (NET) February 2019. Aside from B1051, there will be no obvious booster alternative available for at least several months after Crew Dragon’s launch debut, unless NASA requests that its next contracted Cargo Dragon mission (CRS-17) launch on a new Falcon 9 rocket in March 2019.

Warmer…
If a less lightly-used booster becomes an option for CSA/MDA, there are immediately multiple clear options available as long as SpaceX is will to accept possible delays to subsequent launches to quickly reassign a flight-proven Falcon 9. Falcon 9 B1046 – the first SpaceX rocket ever to launch three orbital-class missions – is being refurbished at SpaceX’s Hawthorne, California facilities a few hundred miles south of Vandenberg. B1047 completed its second successful launch in November 2018 and is being refurbished – along with the twice-flown B1048 – in Cape Canaveral, Florida. Finally, Falcon 9 B1049 completed its second successful launch just days ago (January 11th) and is being processed off of drone ship Just Read The Instructions (JRTI) at this very moment.
B1047 or B1048 have likely been assigned to the imminent NET February 18th launch of Indonesian commsat PSN-6 and SpaceIL’s Beresheet Moon lander, meaning that the best possible option for Radarsat – short of swallowing months of additional delays – is a decision between B1047/B1048 or B1046, with B1049 also a candidate if a slip into March or April is an option. Still, all of those options would require Canada and MDA to fly on a Falcon 9’s third (or fourth) launch, perhaps an unacceptable compromise or perceived risk for certain customers.

Meanwhile, schedule pressures have meant that SpaceX is pushing as hard as possible to prepare three new Block 5 Falcon Heavy boosters for the giant rocket’s second and third launches, scheduled as early as March and April 2019. While unconfirmed, it appears that SpaceX may have chosen to manufacture all three of those boosters one after the other, meaning that the company’s Hawthorne factory would have been primarily focused on delivering those rockets for at least 2-3 months start to finish. In short, it does not appear that there is or will be an unflown Falcon 9 booster available for Radarsat anytime soon.
Whether the customers wait for a new booster to be produced, wait for Crew Dragon’s first launch to wrap up, or accept being the third or fourth launch of a well-scorched Falcon 9, RCM’s next published launch target should offer a hint as to how CSA, MDA, and SpaceX ultimately decided to respond to Falcon 9 B1050’s dip in the Atlantic OCean.

Tesla patent aims to improve common on-road complaint
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.
Suspension Actuator System for a Vehicle@Tesla‘s US20240383297A1 patent introduces an innovative suspension actuator system that transforms vehicle suspension control through an intelligent combination of active and passive control elements.

— SETI Park (@seti_park) November 27, 2024
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 elements—a 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.

Tesla Cybercab gets huge nod of support from Texas DOT official
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.
