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.

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.
In a pointed message on X, Elon Musk warned that firms maintaining significant short positions in SpaceX over time face “very low” survival probability.
The statement comes amid post-IPO volatility for the rocket company, now trading under the ticker $SPCX.

Five weeks after what was described as the largest IPO in history, the stock had fallen roughly 30% from its peak above $2.6 trillion, briefly surpassing Microsoft and Amazon in market value. Short sellers celebrated gains of about $8.7 billion, but Musk’s reply underscores his long-term conviction.
The warning directly echoes a detailed bullish analysis arguing that Starship’s cost reductions could unlock a multi-trillion-dollar space economy. Projects ranging from solar power beamed from orbit and asteroid mining to orbital data centers and Mars terraforming were projected to create over $100 trillion in new market capitalization.
In this vision, SpaceX acts as the essential infrastructure provider, akin to AWS for cloud computing, capturing monopoly-like revenues from launches, crew transport, and data traffic across a rapidly expanding frontier.
This is far from the first time Musk has targeted short sellers. With Tesla, he has repeatedly framed persistent bears as destined for major losses. In July 2024, Musk declared that once Tesla achieves full autonomy and volume production of Optimus robots, “anyone still holding a short position will be obliterated. Even Gates,” referencing Microsoft co-founder Bill Gates’ reported short bets.

Earlier, in 2018, he taunted shorts that they had “about three weeks before their short position explodes,” a remark followed by sharp stock gains. Musk has also called short selling “value destroying” and once suggested it “should be illegal,” viewing it as betting against innovation and progress.
Critics often dismiss Musk’s optimism as hype, especially when near-term metrics like quarterly deliveries or stock fluctuations disappoint.
Yet his pattern remains consistent: framing short positions against his companies as fundamentally misjudging exponential technological leaps. For SpaceX shorts, the message is clear: betting against multi-planetary ambitions and the infrastructure monopoly they enable carries existential risk for the firms involved.
As Musk and supporters see it, the space economy’s upside dwarfs Earth-bound valuation models, making today’s dips temporary in a decades-long ascent.
Tesla has evidently revealed which of its vehicle models will be the first to receive Starlink integration: the Cybercab.
Tesla’s Santana Row showroom now has a full-fledged display of the Cybercab, with an extensive bit of information hung around an exhibit that seems to reveal the vehicle’s newest feature: an integrated Starlink antenna that will enable secure and reliable internet access during trips.

Cybercab is geared toward autonomous ride-hailing for one or two passengers. The production units rolling off the lines at Gigafactory Texas are built without steering wheels or pedals, meaning when public rides begin, passengers will not need to interact with a human being or control the vehicle in any way outside of what appears on the center screen for their entertainment during the ride.

Along the display, Tesla wrote this message about Cybercab:
“Cybercab is built for autonomy. It has no steering wheel, no side mirrors, and no pedals. It goes where you tell it to go and how you want it to, so you can relax along the way. It is hyper aware and responsive to your surroundings, monitoring other drivers, responding to emergency vehicles, utilizing its expertise in the rarest scenarios to help keep you safe.”
Tesla has been teasing a potential Starlink integration for quite some time now. In December, the company hinted at potential Starlink internet terminal integration within its vehicles in a patent that described a vehicle roof assembly with integrated radio frequency (RF) transparency.
The company wrote in its patent application that a new roof design built with materials that differ from the standard metallic or glass elements used in today’s cars would allow it to integrate modern vehicular technologies, in particular, ones that require radio frequency transmission and reception.
Tesla suggested high-strength polymer blends, like Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
This is the first time we’ve seen Tesla officially confirm the Starlink integration into the Cybercab. It’s not much of a surprise considering the company’s intention behind the Cybercab, which is to make travel autonomous.
Productivity will now be at a maximum during a work-related commute, while the center screen could be utilized for Netflix or potentially even live TV for those who are heading to dinner or to a fun activity.
SpaceX has updated its target for the thirteenth integrated flight test of Starship, aiming for as early as Thursday, July 23. The 90-minute launch window opens at 5:45 p.m. CT from the company’s Starbase facility in South Texas.
The target flight was initially rescheduled for today, but SpaceX pushed it back again.
This latest adjustment follows an aborted attempt earlier in the week and reflects the iterative, rapid-development approach that has defined the Starship program. With the vehicle already stacked and ground teams making final preparations, the mission represents another step toward proving the full reusability of the world’s most powerful rocket system.

The original launch attempt on July 16 was scrubbed at T-0 when several Raptor engines on the Super Heavy booster failed to ignite properly. The automatic abort system triggered just as the engines began their startup sequence, preventing liftoff.
SpaceX CEO Elon Musk confirmed that some engines did not start as expected, prompting the decision to replace two Raptors on Booster 20 to ensure reliability. The issue occurred despite a successful full-duration static fire earlier, highlighting the complexities of coordinating 33 engines under flight conditions.
This cautious approach underscores SpaceX’s commitment to safety amid an aggressive test cadence.
Flight 13 builds directly on the lessons from Flight 12 in May 2026. The Super Heavy booster’s primary goals include a successful liftoff, ascent, stage separation, boostback burn, and controlled splashdown in the Gulf of America.
Hardware and software modifications address the off-nominal flip and boostback burn problems from the prior flight, where propellant slosh and engine relight issues led to an uncontrolled impact.
For the Starship upper stage, objectives include deploying 20 operational Starlink V3 satellites, the first real payload of this type, performing a single Raptor engine relight in space, and executing a controlled entry, descent, and splashdown in the Indian Ocean. Propulsion upgrades aim to improve engine-out capability after one vacuum Raptor was lost on Flight 12.
Additional test elements focus on heat shield performance. Six satellites carry cameras to image the tiles during flight, while white-painted tiles and upgraded attachments on flaps and the aft skirt will gather data for future reusability.
The FAA completed its mishap investigation into Flight 12 earlier this month, clearing the regulatory path.
This suborbital mission, the second with V3 vehicles, advances Starship toward operational missions, including potential crewed flights and support for NASA’s Artemis program. Success would mark significant progress in rapid reusability and satellite deployment from the massive system.
