DeepSpace: Rocket Lab bucks the saying that ‘space is hard’ with 4th Electron success
This is a free preview of DeepSpace, Teslarati’s new member-only weekly newsletter. Each week, I’ll be taking a deep-dive into the most exciting developments in commercial space, from satellites and rockets to everything in between. Sign up for Teslarati’s newsletters here to receive a preview of our membership program.
Rocket Lab continues to buck the adage that “space is hard” with its small but increasingly reliable Electron rocket. After a slight range hardware malfunction caused a launch abort just shy of orbit during Electron’s inaugural May 2017 launch attempt, Rocket Lab fixed the issue and returned to flight, successfully completing Electron’s first orbital launch in January 2018. On November 11th, 2018, the rocket completed its first truly commercial launch, placing seven various satellite into Low Earth Orbit (LEO), rapidly followed by Electron’s fourth successful launch on December 16th, barely one month later.
On March 29th, Rocket Lab completed yet another milestone launch for Electron, successfully placing its heaviest payload – an experimental ~150 kg DARPA spacecraft known as R3D2 – into an accurate orbit. Even relative to SpaceX’s barebones Falcon 1 launch campaign, which attempted five launches – two successfully – over a three year career, Rocket Lab’s Electron has progressed at an extraordinary pace, taking less than two years to complete its fifth launch and achieving its first launch success after just one attempt and eight months of flight operations.
Relentless progress
- To find a rocket with a comparable record of success less than two years after its first launch attempt, one must jump back more than half a century to the late 1950s and early 1960s, when Russia and the US were putting their industrial mights to the challenge of achieving spacefaring ‘firsts’. Almost all of those original vehicles – including Redstone, Atlas, Delta, Thor, Titan, and even Saturn V – were able to weather early failures and achieve extraordinary launch cadences just 12-24 months after their debuts.
- None, however, were developed as an entirely commercial rocket with almost exclusively private funds, although ESA’s Ariane 3 and 4 vehicles nearly fit the bill, with exemplary commercial track records and impressive acceleration from debut to high launch cadences.
- Incredibly, Rocket Lab has brought Electron from paper to its fourth successful launch in ~16 months on what can only be described as a shoestring budget relative to all past efforts, perhaps even Elon Musk and SpaceX.
- According to public investment records, the small US-based, New Zealand-operated company may have reached orbit for the first time with less than $100M, including ~$70M in equity investment and unspecified development funding from DARPA in the early 2010s.
- Rocket Lab’s Electron rocket is quite small, measuring 1.2 m (~4 ft) wide, 17 m (56 ft) tall, and 12,500 kg (27,600 lb) at liftoff, anywhere from a quarter to half the size of SpaceX’s Falcon 1, by most measures.
- Electron is capable of placing 150–225 kg (330–495 lb) into either a 550 km (340 mi) sun synchronous orbit (SSO) or a lower low Earth orbit (LEO).
- Electron is advertised with a commercial list price of around $6M.
- Aside from Electron’s industry-defying record of achievement, its R3D2 launch is impressive for another reason: the cost of the payload relative to the cost of launch. For a rocket on its fifth-ever launch, DARPA reportedly spent no less than $25M to fund the development of the experimental R3D2 smallsat, while – as mentioned above – the cost of Electron’s launch could have been as low as ~$6M from ink to orbit.
- In slightly different terms, Electron has now launched a payload that could be 4-5X more valuable than itself after just three prior launch successes and less than two years after beginning operations.
- While ~$30M would not be a huge loss for a military agency like DARPA (FY19 budget: $3.4B), DARPA’s trust in Electron demonstrates impressive confidence in not just Electron, but also Rocket Lab’s standards of manufacturing, operations, and mission assurance.
- Relative to a vehicle like Falcon 9 or Atlas V, Electron’s R3D2 mission would be comparable to launching spacecraft worth ~$250M to $500M after just five launches. Both larger rockets accomplished similar feats, but small launch vehicles are historically known for less than stellar reliability.
Go[ing] forth and conquer[ing]
- Put simply, Rocket Lab has managed to build what appears to be a shockingly reliable small launch vehicle with a budget that would make Old Space companies whimper, all while offering a potential cadence of dozens of annual launches at per-launch costs as low as $6M.
- While the cost-per-kg of a $6M Electron launch is still extremely high relative to larger rockets and rideshare opportunities, what Rocket Lab has achieved is nothing short of spectacular in the commercial spaceflight industry.
- If there ever was an actual ‘space race’ to fill the small launch vehicle void created by the growth of small satellite launch demand, Rocket Lab has won that race beyond the shadow of a doubt. There is still plenty of room for competition and additional cost savings from a customer perspective, but Electron is so early to the party that future competition will remain almost entirely irrelevant for the better part of 2-3 more years.
- According to CEO Peter Beck, the company’s ambition is to sustain monthly Electron launches in the nine remaining months of 2019. Flight 6 hardware is likely already on its way to Rocket Lab’s Mahia, New Zealand Launch Complex 1 (LC-1).
Mission Updates
- The second launch of Falcon Heavy – the rocket’s commercial debut – is still scheduled to occur as early as April 7th, but a slip to April 9-10 is now expected. The massive rocket’s static fire – the first for a Block 5 Falcon Heavy – is set to occur as early as Wednesday, April 3rd.
- After Falcon Heavy, Cargo Dragon’s CRS-17 resupply mission is firmly scheduled for April (April 25th), while the first dedicated Starlink launch is now NET May 2019.
- In late May, SpaceX could launch Spacecom’s Amos-17 spacecraft, effectively free to the customer as part of a settlement following the tragic Amos-6 Falcon 9 anomaly that destroy the rocket, satellite, and large swaths of the LC-40 pad in September 2016.

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.
