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 has reached a notable benchmark in its autonomous driving program after its Robotaxi fleet surpassed one million miles of unsupervised operation. The company made the announcement during its Cybercab event in Austin on September 3.
Tesla Vice President of AI Ashok Elluswamy told attendees he was happy to report the fleet had achieved one million miles of unsupervised Robotaxi operation as a testament to safety.
The new total marked a sharp increase from the 380,000 unsupervised miles Tesla disclosed during its second-quarter 2026 earnings update in late July.
In roughly six weeks, the company added about 620,000 miles. That acceleration followed Tesla’s decision to remove in-vehicle safety monitors from most of its operations outside the San Francisco Bay Area.

Tesla first launched Robotaxi service in Austin in June 2025 with safety drivers present. It later began fully unsupervised rides and expanded into Dallas, Houston, Miami, Orlando, and Tampa. The San Francisco Bay Area remains the exception, where a safety monitor still rides in the vehicle under California permitting rules.
The company has not released a city-by-city breakdown of the one million unsupervised miles.
The milestone arrived as Tesla began offering public Cybercab rides in Austin. The purpose-built vehicle has no steering wheel or pedals and is designed only for autonomous ride-hailing. Production versions joined the existing fleet of modified Tesla vehicles already operating in the service.
Tesla’s unsupervised mileage is growing at a double-digit weekly rate according to earlier company comments, yet its fleet size remains modest compared with established competitors. Waymo has accumulated more than 200 million fully autonomous rider-only miles. Tesla has described its own unsupervised operations as having recorded zero notable incidents in the period leading up to the July update.
The one-million-mile figure reflects Tesla’s shift from supervised testing to broader driverless service in multiple states. It also highlights the company’s strategy of using both existing Model Y vehicles and the new Cybercab to scale its network.

Whether the rapid recent growth continues will depend on further city expansions, regulatory approvals, and the performance of the purpose-built Cybercab in everyday paid rides. Tesla has not specified how many of the latest miles involved the new vehicle versus the rest of the fleet.
The announcement underscores Tesla’s progress toward a larger robotaxi network while illustrating the remaining gap in total autonomous experience relative to longer-operating rivals.
Tesla AI lead Ashok Elluswamy said this week that 24-hour Robotaxi service is close. Replying on X to a rider who wanted Cybercab trips all night, he wrote that the capability would arrive “next month or so” once “the next tech to merge on the v15 plan” is ready.
The comment landed on September 4, one day after Tesla opened public Cybercab rides in Austin. It is the clearest near-term timeline yet for overnight unsupervised operation. Tesla’s paid Robotaxi network currently runs from 6 a.m. to 10 p.m. seven days a week across Austin, Dallas, Houston, Miami, Orlando, and Tampa.
next month or so. the next tech to merge on the v15 plan will enable it.

That 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.
Elluswamy did not name the specific feature or say whether the change would apply first to purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list. The link to Full Self-Driving v15 is nevertheless significant.
Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.
By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states with what the company called an impeccable safety record and no notable incidents caused by the vehicles themselves. Tesla has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.
Overnight service would test that claim in lower-light conditions and would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.
Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale: Tesla has held back mass expansion until more of the v15 stack is merged, citing the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.
If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets.
That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.
Tesla is beginning to roll out Full Self-Driving Supervised v14.3.9 with a new active safety layer that can take control even when the driver is operating the car manually.
Tesla AI said the software can activate FSD on the driver’s behalf when an imminent collision is detected and Automatic Emergency Braking may not be enough. It may also engage if the system detects heavy distraction or an accidental FSD disengagement.
FSD Supervised v14.3.9 starting to roll out shortly
This release includes a new active safety feature set: FSD Supervised can now activate on your behalf when an imminent collision is detected and Automatic Emergency Braking (AEB) may not be enough.
It may also engage if we…
— Tesla AI (@Tesla_AI) September 4, 2026
The capability is essentially Automatic Collision Evasion. However, unlike conventional AEB, which mainly applies the brakes in a straight line, this feature can use steering, braking, and acceleration together if the car calculates that stopping alone will not prevent impact and a safer path exists. The system may change lanes or move toward a shoulder when conditions allow, then continue driving after the immediate threat is handled rather than simply coming to a stop.
The intervention is meant as a last-resort safety net, not a replacement for attentive driving.
Tesla Full Self-Driving v14.3.7 early review: FSD saved me from an accident
Tesla’s own description still frames FSD as supervised assistance. Secondary reports on internal release notes say the feature can fire while the car is being driven manually if cabin-camera monitoring suggests the driver is not sufficiently attentive, such as reaching toward the back seat, or if FSD appears to have been turned off unintentionally.
After the emergency maneuver, the car is expected to alert the driver and request a return to manual control.
The safety case is straightforward. Many collisions happen in the last second because a driver is looking away, fumbles a control, or faces an obstacle that braking cannot fully solve. A system that can both recognize that AEB is insufficient and execute a coordinated evasive path can reduce those remaining high-severity events.
Re-engaging after accidental disengagement also addresses a practical failure mode: a small steering nudge that drops FSD at the worst moment. The advantage is a background safety net that uses the same vision stack already running in v14, instead of leaving the car solely to emergency braking once the driver is no longer in command.
The feature still depends on FSD being enabled and, according to reports, an active FSD purchase or subscription. It does not make the vehicle unsupervised. Drivers remain responsible, and Tesla has not published how often the system is expected to intervene or how it will handle false positives.
If the rollout is conservative and the false-alarm rate stays low, the update is a meaningful step: FSD is no longer only a feature the driver turns on. In the rare moments when disaster is already forming, it can step in.
