Rocket Lab assembling first reusable Neutron rocket hardware
Rocket Lab appears to have made significant progress since revealing the state of hardware development for its next-generation Neutron rocket in a September 2022 investor update.
At the time, the company shared photos of early work on prototypes of smaller Neutron structural elements, as well as progress building the giant molds that will be used to ‘lay up’ the rocket’s carbon fiber composite tanks and airframe. Rocket Lab also showed off acquisitions of some of the supersized manufacturing equipment that will be used to build the giant rocket, as well as the beginnings of a dedicated Neutron factory in Virginia.
Four months later, photos shared by CEO Peter Beck show that Rocket Lab has progressed to full-scale carbon fiber hardware manufacturing. In December 2022, Beck shared a photo of a full-size Neutron tank dome in the middle of production. A month later, Beck shared a photo of work on both halves of a Neutron booster tank dome. Measuring around seven meters (23 ft) wide, the latter component is already on track to become one of the largest carbon fiber structures ever prepared for a rocket once the halves are joined. And once two more halves are built and assembled, Rocket Lab could soon be ready to start testing full-scale Neutron tank hardware – a crucial milestone for any new rocket.
The update that's rolling out to the fleet makes full use of the front and rear steering travel to minimize turning circle. In this case a reduction of 1.6 feet just over the air— Wes (@wmorrill3) April 16, 2024
Announced in March 2021 and properly unveiled in December 2021, Neutron is a partially-reusable two-stage rocket designed to launch up to 15 tons to Low Earth Orbit (LEO) using liquid methane and oxygen propellant. Neutron measures 42.8 meters (140.4 ft) tall and up to seven meters (23 ft) wide. Its stout, ballistically-optimized design means that it’s simultaneously 40% shorter and up to 190% wider than SpaceX’s workhorse Falcon 9 rocket.
Design differences aside, Neutron is the first rocket that has been obviously designed as an answer to Falcon 9, which has become one of the most prolific, cost-effective, and routinely reusable rockets in the world over the last five or so years. Depending on how much Rocket Lab can sell Neutron for while still breaking even, Neutron has the potential to give Falcon 9 a serious run for its money – or at least force SpaceX to lower its prices. Like Falcon 9, Neutron will have a reusable booster, a reusable payload fairing, and an expendable upper stage. Its booster will also have nine (Archimedes) engines and the upper stage will be powered by one engine. At liftoff, Neutron will produce up to 674 tons (1.49M lbf) of thrust to Falcon 9’s 770 tons (1.7M lbf).



Unlike Falcon 9, Neutron’s similarly-sized reusable fairing is integral, meaning that it will stay permanently attached to the booster. But despite the added mass of the integral fairing and the rocket’s significantly shorter layout, Rocket Lab says that Neutron will be able to launch up to 13 tons (~28,700 lb) to LEO if the booster lands on a barge downrange. Using the same approach with a deployable fairing, Falcon 9 has launched up to 16.7 tons (~36,800 lb) to LEO. That 23% performance gap may seem significant, but the reality is that only SpaceX’s own Starlink and Dragon missions have ever needed Falcon 9 to launch more than 13 tons to orbit.
If Neutron can consistently launch ~25% less payload than Falcon 9 to all Earth and near-Earth orbits, virtually every commercial launch contract that’s currently a SpaceX shoo-in could be within reach of Rocket Lab within several years. The challenge, of course, is building Neutron and making sure the ambitious rocket and its clean-sheet Archimedes engine work as expected and can be reused as easily as Falcon 9.
The company is attempting to get there with its far smaller Electron vehicle, but Rocket Lab has never reused a rocket. And five and a half years after Electron’s debut, the company has never launched more than nine times in one year. SpaceX is about to reuse a Falcon booster for the 140th time and launched 61 times in 2022 – a lead that may prove almost impossible to close. There’s also the fact that the size gap between Rocket Lab’s rockets is so extreme that Neutron could likely launch a fully-fueled Electron into orbit.
But again, SpaceX serves as a demonstration that what Rocket Lab hopes to achieve is not impossible. SpaceX went directly from Falcon 1 (about twice as large as Electron) to Falcon 9 V1.0 (about 30% smaller than Neutron) after just two successful launches of the smaller rocket. Electron has successfully launched 29 times since May 2017 and Rocket Lab is already learning about reusability through the smaller rocket. The challenges facing Rocket Lab are huge, but Neutron still remains the most promising SpaceX competitor currently in development. Kicking off full-scale Neutron tank testing just 2-3 years after the rocket was revealed would only reiterate its strengths. Stay tuned to see how much Neutron progress Rocket Lab can make in 2023.

Elon Musk confirms Tesla is already rolling out a new feature for in-car Grok
Tesla is already making in-car Grok more robust with a simple but effective feature that CEO Elon Musk says is “coming.”

Tesla CEO Elon Musk has confirmed that the company will roll out a new feature for in-car Grok as it is rolling out to vehicles for the first time.
Grok was just recently added as a feature to Tesla vehicles within the past week, but owners are already requesting some small changes to make it more convenient to use.
Tesla debuts hands-free Grok AI with update 2025.26: What you need to know
The first is already on the way, Musk confirmed, as WholeMarsBlog requested a simple, but useful feature for Grok as it is used within Tesla vehicles.
Whole Mars requested that “Hey Grok” be used as a wake word, automatically activating the AI assistant without having to touch any buttons. Musk confirmed it is already in development and on the way to vehicles:
Coming
— Elon Musk (@elonmusk) July 16, 2025
This feature is incredibly similar to that of “Hey Siri” with iPhones and other iOS devices. The phone will recognize your voice and hear that prompt, automatically activating Siri. Apple’s assistant will then perform whatever task it is asked to perform. It’s a simple but effective performance feature.
Grok is already getting its first reviews from owners as it rolls out to owners for the first time. It is a long time coming, too. Tesla has been hinting that Grok would be enabled in the vehicles for a while now, and it just started its initial rollout last week.
After using @grok in my Tesla tonight, I’m insanely impressed.
I honestly went into it a bit skeptical on how useful it would actually be, but I asked it some real genuine questions and it nailed it every time.
Asked it if I take my Tesla to San Francisco next week, where… pic.twitter.com/R0QrK347vi

Grok is available in vehicles with the AMD chip and requires Premium Connectivity or a WiFi connection to use.

Tesla reveals key detail of Supercharger Diner, but it’s bigger than you think
Tesla has finally released one key detail about the Supercharger Diner, and it is bigger than what it appears at face-value.

Tesla has revealed a key detail of its Supercharger Diner as its launch date appears to be nearing, based on what we are seeing at the site currently.
The Supercharger Diner is located on Santa Monica Boulevard in Los Angeles and was first proposed as an idea by CEO Elon Musk back in 2018. Musk envisioned a drive-in movie-style 1950s-inspired diner that would feature elements such as servers on roller skates, large movie screens, and a menu inspired by classic treats from several decades ago.
A project that first broke ground in 2023, the Supercharger Diner has been in development for over two years, as Tesla performed demolition work at the site back in February of that year.
It has slowly moved forward, and drone footage shot this week seems to show things are nearly up and running. Musk even mentioned that he had eaten at the Diner Supercharger this week.
There are still details that Tesla has yet to announce and confirm. The most important thing is regarding the menu that will be served at the diner.
Tesla has not hinted at what it will be making for patrons at the restaurant, but Musk commended the food and said the diner would be one of the coolest spots in LA.

However, we now have details on another important thing about the restaurant: the hours.
Images taken by Aaron Cash of ABetterTheater.com show the diner will be open 24/7, as it appears on the front doors of the diner:

At first thought, it seems this will operate like any other diner, as many are open for 24 hours a day. Diners typically serve large menus with numerous options, catering to the tastes and moods of anyone who walks in.
People of all walks of life eat at diners, as the food is typically affordable, tasty, and available at any hour to serve those who are night owls or those who work non-typical schedules.
However, Tesla is a bit different, and it seems that this new venture into food service could eventually transition from human servers and cooks to robots, most notably the company’s in-house project of Optimus.
It is something straight out of a Star Wars movie. I can think of Obi-Wan Kenobi visiting Dex in his diner in Attack of the Clones to figure out where a poison dart was sourced from:
Eventually, Optimus will likely be working as an employee in the Tesla Diner, and 24/7 operation will be performed by the humanoid robot that aims to eliminate trivial tasks from humans.

First glimpse of Tesla Model Y with six seats and extended wheelbase
It’s longer and taller than the regular Model Y, and it has a cool new badge.

Tesla’s extended wheelbase Model Y has been announced by the electric vehicle maker on its official Weibo page in China. At the same time, details of the upcoming vehicle have been listed in the China Ministry of Industry and Information Technology’s (MIIT) new regulatory catalog.
The extended wheelbase Model Y
Tesla announced the upcoming vehicle on its official Weibo page, with the company noting that the new car will be called the “Model Y L.” Images posted by the company showed that the Model Y L will feature a “Model Y” badge with a stylized “Y” graphic. A teaser image of the vehicle taken from its side also emphasizes the extra space that was gained from its extended wheelbase.
The MIIT listing for the Model Y L indicated that the vehicle would be 4,976 mm long, 1,920 mm wide, and 1,668 mm high. Its wheelbase was listed in the MIIT’s catalog as 3,040 mm. In comparison, the new Model Y is currently 4,797 mm long, 1,920 mm wide, and 1,624 mm high, with a wheelbase of 2,890 mm.
Six seats and some power
Most notably, the extended wheelbase Model Y was listed in the MIIT regulatory catalog as a six-seat model. The vehicle is also listed with the product model number TSL6500BEVBA0, as noted in a CNEV Post report. And as hinted in Tesla China’s Weibo post, the vehicle will be released sometime in the fall.
The Model Y L is listed as a dual motor vehicle with peak power outputs of 142 kW and 198 kW for the front and rear motors. The vehicle is also listed with ternary batteries supplied by LG Energy Solution, and it reportedly weighs 2,088 kilograms (4603 pounds). In comparison, the new Model Y Dual Motor AWD weighs 4391 pounds.
Tesla China has not hinted at the price of the new Model Y L, though expectations are high that the vehicle will be priced at about RMB 400,000 ($55,764). It also remains to be seen if the Model Y L will also be produced in Tesla’s vehicle factories in the United States and Germany.
