Report: SpaceX to launch at least five back-to-back Crew Dragon missions for NASA
Update: Wasting no time at all, NASA has confirmed the Ars Technica report one day later, announcing that rookie astronauts Nicole Mann and Josh Cassada have been reassigned from Boeing Starliner missions to SpaceX’s Crew-5 Crew Dragon launch – currently no earlier than August 2022.
Ars Technica’s Eric Berger reports that NASA has begun the process of moving a number of astronauts assigned to Boeing’s ailing Starliner spacecraft to a SpaceX Crew Dragon mission scheduled no earlier than August 2022.
Per sources close to Berger, NASA has chosen to reassign two rookie astronauts to Crew Dragon as hopes of a crewed Starliner launch – and thus an opportunity for them to gain hands-on spaceflight experience – in the next 6-12 months continue to wither. Barring surprises, the implied change of plans behind those actions means that SpaceX now appears to be scheduled to fly five operational NASA Crew Dragon missions back to back before Boeing’s Starliner flies a single astronaut – let alone its first operational mission with four crew aboard.
In December 2019, nine months after Crew Dragon’s own uncrewed March 2019 debut, Starliner lifted off for the first time on a ULA Atlas V rocket. However, whereas Crew Dragon performed a practically flawless orbital launch, space station rendezvous, docking, departure, reentry, and splashdown on its first try, Starliner’s Orbital Flight Test (OFT) went horribly wrong as soon as it separated from Atlas V.
Due to shoddy prelaunch testing that failed to detect several gaping holes in Starliner’s software, the spacecraft effectively lost control as soon as it was under its own power. Aside from making ground communication and control far harder, Starliner burned through most of its propellant and pushed most of its maneuvering thrusters past their design limits in the first hour or two after launch. Due to the catastrophic software failure and lack of propellant margins, NASA unsurprisingly called off a planned space station rendezvous and docking attempt and Boeing ultimately ordered Starliner to reenter a few days after launch.
Mere hours before reentry, Boeing apparently detected and fixed another major software error at the last second, potentially preventing Starliner’s propulsion and service module from smashing into the capsule’s fragile heat shield and dooming the spacecraft to burn up during reentry. Ultimately, it’s likely that the only reason Boeing didn’t suffer a total loss of vehicle (LOV) during Starliner’s OFT debut spacecraft was dumb luck. Had the initial clock error been worse, Starliner could have failed to reach orbit entirely or burned through all of its propellant, resulting in an uncontrolled reentry. Had there been no clock issue, it’s hard to imagine that Boeing’s software team would have attempted the panicked, impromptu bug hunt that detected and fixed the service module recontact issue.
Now, 22 months after Starliner’s catastrophic OFT, Boeing has been forced to stand down from a second self-funded orbital flight test (OFT-2) due to the last-second discovery of more than a dozen malfunctioning valves on the second spacecraft’s service module. Aside from raising the question of how Boeing and NASA yet again failed to detect a glaring Starliner issue until the day of launch, Starliner’s valve issues appear likely to cause another multi-month delay as Boeing is forced to investigate the problem, find the root cause, and implement a fix on all impacted service modules.
NASA reassigning some of the astronauts scheduled to helm Starliner on its Crewed Flight Test (CFT) and first operational mission to Crew Dragon’s August 2022 Crew-5 launch seemingly implies that the space agency is not confident that Boeing will have completed Starliner OFT-2, passed extensive post-flight reviews, and readied another Starliner for CFT by Q3 2022. Given that NASA took some 14 months to OK Crew Dragon’s Demo-2 crewed flight test after Demo-1’s March 2019 success and a catastrophic April 2019 failure during a ground test of the recovered capsule, it’s not unreasonable to assume that NASA will take about a year after OFT-2 to approve Starliner’s first crewed flight test.
If significant issues arise during OFT-2, which is now unlikely to occur before early 2022, a year-long gap is even more likely. Ultimately, that means that there is now a significant chance that SpaceX’s Crew Dragon spacecraft will complete not just five – but six – back-to-back operational NASA astronaut launches before Starliner is ready for its first operational ferry mission. SpaceX, in other words, is now expected to singlehandedly hold the line and ensure biannual NASA access to and from the International Space Station (ISS) for more than two years despite charging NASA $2 billion less than Boeing (~$5B vs ~$3B) to develop Crew Dragon.
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.

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.
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.
