SpaceX installs new Starship on static fire test stand
SpaceX may be focused on preparing Starship S24 and Super Heavy Booster 7 for their potentially imminent orbital launch debut, but the rest of the company’s Starship factory isn’t just sitting around.
The laser focus on carefully testing Ship 24 and Booster 7 may have limited the effectiveness of Starbase rocket production, but the factory has continued to produce new ships and boosters. SpaceX has even conducted some limiting testing of a pair of prototypes meant to follow in the footsteps of S24 and B7. In mid-January, that process entered a new and more active phase as SpaceX transported Starship S25 from the factory to the launch pad.
The trip is not Ship 25’s first. Starship S25 first headed to SpaceX’s South Texas launch and test facilities on October 19th, 2022, shortly after the vehicle was fully assembled. Around three weeks of testing followed, and now Ship 25 is back for more.

Ship 25
The first round of tests was thorough and put Ship 25 through a pneumatic proof test, multiple cryogenic proof tests, and likely a few simulated thrust tests using six hydraulic rams.
“Ship 25 was removed from SpaceX’s other Starship test stand on November 8th, it was rolled back to Starbase’s Starship factory. Ship 25 first rolled to the launch site on October 19th and has since completed four visible tests. On October 28th, Ship 25 survived a pneumatic proof test that showed that its tanks were leak-free and capable of surviving flight pressures (roughly 6-8.5 bar or 90-125 psi). Three cryogenic proof tests followed on November 1st, 2nd, and 7th. The first cryoproof was likely just that – a test that pressurized Ship 25’s tanks and filled them with cryogenic liquid nitrogen (LN2) or a combination of liquid oxygen and LN2.
The next two tests likely took advantage of the customized test stand, which has been semi-permanently outfitted with a set of hydraulic rams that allow SpaceX to simulate the thrust of six Raptor engines while Starship’s structures are chilled to cryogenic temperatures and loaded with roughly 1000 tons (~2.2M lb) of cryogenic fluids. If a Starship can survive those stresses on the ground, the assumption is that it will likely survive similar stresses in flight.”

As usual, SpaceX didn’t comment on the development or indicate how that initial proof testing had gone, but Ship 25’s January 14th, 2023 return to the launch site all but guaranteed that that testing had gone more or less according to plan. On January 17th, SpaceX lifted Ship 25 onto Starbase’s only Starship static fire test stand, further confirming that Ship 25 proof testing went to plan.
Soon after its November 2022 return to Starbase’s build site, six Raptor engines were moved into the High Bay and installed on Ship 25. The Starship’s aft was then likely buttoned up with a heat shield before it headed to the test site to begin its static fire test campaign. That campaign could tell us a lot about the status of Starship prototypes. To date, only two Ships have completed full six-Raptor static fire tests, and both took days, weeks, or months to build up to those six-engine milestones with multiple smaller tests. If Ship 25 were to skip those preliminary tests and immediately conduct a six-engine static fire, it would be a sign that SpaceX is significantly more confident in the current Starship design.
Booster 9
Ship 25 is believed to be paired with Super Heavy Booster 9, which recently finished its own round of proof tests. About two months behind Ship 25, Booster 9 rolled out of its Starbase assembly bay and headed to the launch site on December 15th, 2022. The Super Heavy prototype ultimately completed two partial cryogenic proof tests on December 21st and 29th, during which it was likely loaded with around a thousand tons of liquid nitrogen to simulate explosive liquid oxygen and methane propellant. Booster 9 then returned to Starbase’s factory on January 10th, 2023.
Assuming those tests went well, Raptor engine installation could begin at any moment. However, thanks to significant design changes and upgrades present on Booster 9, outfitting and testing this Super Heavy could take longer than usual. Many smaller changes are present, but the most significant by far is the addition of an upgraded version of Raptor. The engine’s combustion-related hardware is likely the same as the Raptor V2 engines present on Booster 7, Ship 24, and Ship 25. But the hardware used to steer each engine – called thrust vector control (TVC) – has been completely changed.
Instead of using a complex web of plumbing and hydraulic power units bolted to the side of Super Heavy, Booster 9’s 13 central Raptors will be electrically steered. That has allowed SpaceX to remove those power units (streamlining Booster 9’s exterior) and reduce the already rats nest of plumbing required to fuel, control, power, and steer dozens of high-performance rocket engines on one booster. SpaceX has been testing electric Raptor TVC for months at its McGregor, Texas development facilities, but it’s unclear if the new technology has progressed to the point that 13 upgraded engines are ready to be installed on Booster 9. In the meantime, SpaceX may install Booster 9’s fixed outer ring of 20 Raptor V2 engines – none of which gimbal or need new electric TVC hardware.
Once all 33 engines are installed, it’s likely that Booster 9 will be thoroughly tested to ensure that all 13 electrically-steered engines work well together before, during, and after numerous static fire tests. SpaceX will also need to verify that the batteries likely powering those new systems function as expected. During the peak stresses they will likely experience, the electric TVC could need to rapidly redirect more than 3000 tons (~6.6 million lbf) of thrust multiple times per second. The peak power required from Super Heavy’s batteries will likely be immense as a result.
For now, the start of Super Heavy B9’s own static fire test campaign could be months away and will have to wait until Starbase’s only orbital launch mount – currently occupied by Booster 7, Ship 24, and Starship’s first orbital launch campaign – is vacated. With that orbital launch debut unlikely to happen before March 2023, Booster 9 has plenty of time to relax inside Starbase’s Wide Bay while Ship 25 begins static fire testing at a separate stand.

Tesla Semi sends clear message to Diesel rivals with latest move
The truck is being built at a dedicated facility in Sparks, Nevada, just next to its Gigafactory Nevada facility.
Tesla has officially launched Semi production at what will be a mind-boggling rate of approximately 50,000 units per year.
The truck is being built at a dedicated facility in Sparks, Nevada, just next to its Gigafactory Nevada facility.
The company finally announced on April 29 that the first Tesla Semi truck has rolled off its new high-volume production line at the factory. This marks the transition from limited pilot builds to scaled manufacturing for the Class 8 all-electric heavy-duty truck, nearly nine years after its dramatic 2017 unveiling.

Tesla initially promised high-volume deliveries by 2019–2020, but battery supply constraints and prioritization for passenger vehicles delayed progress. The new 1.7-million-square-foot factory, purpose-built next to Gigafactory Nevada’s 4680 cell production lines, resolves those bottlenecks through deep vertical integration.
The Semi uses Tesla’s structural battery packs with cylindrical 4680 cells manufactured on-site. This integration enables efficient supply, reduced logistics costs, and the potential for high output. The factory is designed for an eventual annual capacity of approximately 50,000 trucks, positioning Tesla to address growing demand in long-haul freight electrification.
Tesla is using a redesigned Cybertruck battery cell to mitigate Semi challenges
Operating economics favor the Semi through dramatically lower fuel and maintenance costs compared to traditional diesel rigs, and companies involved in a pilot program for the Semi with Tesla have shown that.
Electricity is far cheaper than diesel on a per-mile basis, while the electric powertrain features fewer moving parts, reducing service intervals and lifetime expenses. Early deployments with customers like PepsiCo and others have validated these advantages in real-world service.
The Nevada factory’s ramp-up is targeted for full volume output before the end of June 2026, aligning with broader Tesla production goals for 2026. This includes parallel efforts on other new vehicles while expanding the Megacharger infrastructure to support widespread adoption.
By localizing battery and truck production, Tesla gains advantages in cost, quality control, and scalability that many competitors sourcing cells externally lack. The start of high-volume Semi production represents a pivotal step in Tesla’s strategy to electrify heavy transportation, potentially accelerating the shift toward zero-emission freight across North America and beyond.
As output increases, the Semi could reshape long-haul logistics with its combination of performance, efficiency, and sustainability.

Tesla gives HW3 owners another massive update
It was an “at last” moment for HW 3 owners, who have waited for an update on the capabilities of their vehicles for some time. After CEO Elon Musk finally admitted last week that the HW3 vehicles would not be capable of unsupervised FSD, it appears Tesla is bringing a new, more transparent tone to those owners.
Tesla is giving Hardware 3 vehicle owners another massive update, the second major communication the company has given to those drivers after what seemed like years of being left out to dry.
The company, which plans to launch a Full Self-Driving version 14 iteration that is compatible with these cars, which have older chips, is now planning to expand the rollout of the v14 Lite offering to other markets, it said on X.
Tesla said:
“Following future rollout of FSD V14 Lite for HW3 vehicles in the US, we plan on expanding V14 Lite to additional international markets. This update ensures that HW3 vehicle owners will continue to benefit from ongoing software updates. Since international rollout is subject to several factors (completion of technical verification, regional adaptation & relevant regulatory approvals), we can’t provide definitive dates at the moment, but will provide updates on a rolling basis.”
This announcement comes at a critical time for HW3 owners, many of whom purchased Full Self-Driving (FSD) capability years ago with promises of ongoing support and future-proofing.

HW3, introduced in 2019, powers vehicles from roughly 2019 to early 2023 models. While newer AI4 hardware has advanced rapidly, HW3 owners have felt increasingly left behind, with their last major update stuck around version 12.6 since early 2025.
It was an “at last” moment for HW 3 owners, who have waited for an update on the capabilities of their vehicles for some time. After CEO Elon Musk finally admitted last week that the HW3 vehicles would not be capable of unsupervised FSD, it appears Tesla is bringing a new, more transparent tone to those owners.
V14 Lite represents a significant optimization effort. Tesla has confirmed it will bring many core features of the full V14 release, currently running on more powerful hardware, to the more constrained HW3 platform.
Expected capabilities include improved handling of complex urban scenarios, better reverse driving, enhanced parking features, and smoother overall autonomy, albeit in a “lite” form tailored to HW3’s compute limits. Tesla’s head of Autopilot, Ashok Elluswamy, noted during the Q1 2026 earnings call that the update is targeted for late June in the U.S.
Tesla is releasing a modified version of FSD v14 for Hardware 3 owners: here’s when
The international expansion is particularly meaningful for owners in Europe, Asia, Australia, and other regions where FSD rollout has lagged due to regulatory hurdles.
Tesla emphasized that timing remains fluid, dependent on “technical verification, regional adaptation & relevant regulatory approvals.” No firm dates were provided, but the company pledged rolling updates as milestones are achieved.
This move addresses growing concerns that Tesla might abandon legacy hardware. With the recent admission that its capabilities are limited and not capable of Tesla’s grand autonomy ambitions, owners are finally in the light of truth, with more honesty being put forth as the company navigates this chapter.
For Tesla, keeping HW3 relevant strengthens customer loyalty and protects the value of older vehicles. It also buys time as the company pushes toward broader regulatory approvals and unsupervised autonomy on newer platforms.
While V14 Lite isn’t the full unsupervised experience once promised, it delivers tangible improvements and signals that HW3 owners are not being forgotten.
As Tesla continues its rapid AI and autonomy evolution, this update underscores a key principle: software can breathe new life into existing hardware. For tens of thousands of HW3 drivers worldwide, V14 Lite could mark the beginning of a renewed era of confidence in their vehicles.

SpaceX Board has set a Mars bonus for Elon Musk
SpaceX has given Elon Musk the goal to put one million people on Mars.
SpaceX’s board approved a compensation plan for Elon Musk that ties his pay directly to colonizing Mars and building data centers in outer space. The details surfaced this week after Reuters reviewed SpaceX’s confidential registration statement filed with the Securities and Exchange Commission, making it one of the first concrete looks inside the company’s financials ahead of a public offering.
The pay package will reportedly award Musk 200 million super-voting restricted shares if the company hits a market valuation milestone, with the most ambitious targets going further. To unlock the full award, SpaceX would need to reach a $7.5 trillion valuation and help establish a permanent human settlement on Mars with at least one million residents. Additional incentives are tied to developing space-based computing infrastructure capable of delivering at least 100 terawatts of processing power.
SpaceX wins its first MARS contract but it comes with a catch
Long before SpaceX filed anything with the SEC, Elon Musk had already spent years framing Mars colonization as an insurance policy against human extinction. The philosophy traces back to at least 2001, when Musk first began researching Mars missions independently, before SpaceX even existed. By 2002 he had founded the company with Mars as the stated long-term goal.
In a 2017 presentation at the International Astronautical Congress, Musk outlined the specific vision that still underpins SpaceX’s architecture today. He described a self-sustaining city on Mars requiring roughly one million people to become viable, the same number now written into his compensation package.
SpaceX’s Starship, still in active development, was designed from the ground up to support the eventual colonization of Mars. Musk has stated publicly that getting the cost per ton to Mars below $100,000 is necessary to make mass migration economically feasible. Everything from Starship’s payload capacity to its full reusability targets flows from that single constraint. One can say that Musk’s latest compensation package has put a formal valuation on Mars for the first time.
SpaceX is targeting an IPO around June 28, Musk’s birthday, at a valuation of approximately $1.75 trillion. Between the Mars rover contract, the Golden Dome software group, Space Force satellite launches, and now a pay structure built around interplanetary colonization, SpaceX has become the single most consequential contractor in American space and defense. The IPO will put a public price tag on all of it for the first time.
