SpaceX’s South Texas Starship factory prepares for major upgrades
In what is probably a sign of things to come for SpaceX’s nascent Florida Starship factory, the company’s original Starbase facility in South Texas may be about to graduate from tents to more permanent buildings.
More than two years ago, in late 2019, SpaceX followed in the footsteps of Tesla and began constructing a surprisingly advanced factory out of a series of tents. Instead of Model 3s, though, SpaceX would be building and assembling sections of the largest and most powerful rocket ever built. Measuring approximately 120 meters (~390 ft) tall, 9 meters (~30 ft) wide, ~5000 tons (~11M lb) fully fueled, and capable of producing around 7500 tons (~16.5M lbf) of thrust at liftoff, Starship is a fully reusable rocket that aims to perfect what SpaceX has already achieved with partially reusable Falcon 9s and Heavies.
Nonetheless, Starship manufacturing represents a substantial departure from the methods SpaceX uses to build Falcon rockets.
Instead of heavily leaning on horizontal integration (meaning that the rockets are primarily assembled in a horizontal orientation), Starship and its Super Heavy booster are almost exclusively assembled vertically. Excluding the machining of major loadbearing structures, Starship manufacturing generally begins with giant rolls of thin (3-4mm or ~0.15 in) stainless steel. SpaceX uses a custom tool to unspool the sheet metal, cuts off a roughly 28-meter (~92 ft) long strip, and then welds the ends of that strip together to produce a cylindrical barrel. Repeat that process 57 times and you end up with enough rings to assemble a full Super Heavy booster and most of a Starship.
However, using increasingly custom tools, SpaceX first stacks and welds those individual rings together to form sections of two, three, four, or five. Each section is then prepared for its specific role with a range of cutouts, plumbing, reinforcements (vertical stringers or circumferential stiffeners), thrust structures (the plates that Raptor engines attach to), and other add-ons. Most importantly, certain stacks of rings are mated with large steel domes – welded together out of prefabricated steel plates – to form forward, common, and aft dome sections. For Starship, SpaceX also assembles the ship’s conical nose section in a similar manner.
Virtually all ring, dome, and nose assembly work is conducted in one of three massive tents – each about 114m x 35m (375′ x 110′) – that form the backbone of Starbase’s Starship factory. Finally, SpaceX has built a series of massive open-air bays where, once fully outfitted, each ship and booster section is stacked in a specific order and welded together to complete the basic structures of Starship and Super Heavy.
While SpaceX continues to speed towards the completion of Starbase’s largest and tallest Starship assembly bay yet, the latest news centers around Starbase’s tents. After physically relocating a smaller but still substantial tent believed to be used basic metalwork (laser/water cutting, presses, etc.), SpaceX has rapidly broken ground and partially completed the foundation of a massive, new building believed to be the start of an upgraded Starship factory.
According to RGV Aerial Photography, SpaceX isn’t merely expanding the main three-tent factory with a fourth larger, permanent building. Instead, it reportedly aims to replace all of Starbase’s tents with a single 300,000-square-foot (~28,000 square meter) building that will be about 18 meters (60 ft) tall and likely measure around 800 feet (250m) long and 400 feet (120m) wide. Starbase’s tents are roughly the same height but their tented roofs mean that only a fraction of that height can be used for ring work and only a fraction of the floor space for taller nose work.
In comparison, a 300,000 square-foot building would have almost two and half times as much covered floor space as Starbase’s three tents – all of which can theoretically be used for ring and nose section assembly. In fact, with a mostly flat 18-meter roof, SpaceX could feasibly expand most ‘stacks’ by a ring or two, which would reduce the number of sections (and thus stacking operations) needed to assemble a ship or booster.
All told, while tents (“sprung structures”) can clearly be indefinite solutions for things like automotive manufacturing, Starship production is one case in which a more permanent flat-ceiling building is undeniably superior. With more than two years of experience and data to draw from, SpaceX may finally be confident enough in its present-day Starship production methods to commit to the construction of Starbase’s next evolution. Stay tuned to see where it leads.
SpaceX announced today that it commenced its first-ever public bond offering, marking a significant step in the newly public company’s capital markets strategy.
The company announced an offering of senior unsecured notes expected to raise at least $20 billion.
The move comes just a short time after SpaceX completed one of the largest initial public offerings in history. In mid-June, the company priced shares at $135 and raised more than $85 billion, propelling founder Elon Musk’s net worth past the trillion-dollar mark and giving the firm substantial liquidity.

According to the company’s SEC filing, the net proceeds from the notes will be used primarily to repay in full the outstanding borrowings under its existing bridge loan facility, cover related fees and expenses, and fund general corporate purposes. The offering is being conducted under Rule 144A, as well as Regulation S, targeting qualified institutional buyers and non-U.S. investors. Notes will be unsecured obligations ranking equally with other unsubordinated debt.
The $20 billion bridge loan was used to refinance approximately $17.5 billion in higher-cost “junk” debt tied to X and xAI. SpaceX had merged with xAI in February 2026 in an all-stock deal. The bridge facility, which matures in September 2027, had represented the bulk of SpaceX’s long-term debt.

In connection with the bond launch, SpaceX disclosed it held approximately $100.8 billion in cash and cash equivalents as of June 19. Investor calls began on the announcement date, with pricing and launch expected shortly thereafter. Rating agencies have assigned investment-grade ratings to the proposed bonds, reflecting confidence in SpaceX’s dominant position in commercial launches and the growth trajectory of its Starlink internet offering.
The debt raise also allows SpaceX to optimize its balance sheet by replacing short-term, higher-cost bridge financing with longer-date, lower-cost fixed-income securities. This provides greater financial flexibility to support capital-intensive initiatives, including the development of Starship, the expansion of the Starlink constellation, and the integration of AI capabilities following the xAI combination.
SpaceX shares (NASDAQ: SPCX) fell sharply on the news, dropping over 16 percent overall on the market on Monday. The stock had surged initially after debuting but pulled back amid profit-taking and broader market dynamics.
Overall, the bond offering underscores SpaceX’s transition to a mature public company with access to diverse funding sources. It positions the firm to pursue its long-term vision of multiplanetary expansion and AI infrastructure, while maintaining a disciplined approach to its capital structure in a high-growth but capital-heavy industry.
SpaceX confirmed today that it has officially signed its third massive compute deal, providing compute at its Colossus data center in Southaven, Tennessee.
Reflection AI will gain immediate access to NVIDIA GB300 chips at SpaceX’s Colossus 2 data center. In return, Reflection will pay SpaceX $150 million per month starting on July 1, with total payments reaching approximately $6.3 billion if the contract runs through its duration, which is until 2029. Either party can terminate the agreement with 90 days’ notice after the initial three-month period.
CNBC first reported the deal.

This latest partnership highlights SpaceX’s strategy of commercializing its massive Colossus supercomputing infrastructure, originally developed to power Elon Musk’s Grok AI models. The company has rapidly expanded its customer base in the AI sector following its February 2026 merger with xAI, a transaction that valued the combined entity at $1.25 trillion.
SpaceX has previously signed significant compute deals with other major players.
It granted Anthropic exclusive access to the full capacity of its Colossus 1 data center, which exceeds 300 megawatts and includes over 220,000 NVIDIA GPUs. Details from SpaceX’s IPO filings indicate Anthropic will pay $1.25 billion per month through May 2029, potentially generating around $45 billion over the term of the deal.
Additionally, Google agreed to pay SpaceX $920 million per month for compute capacity from October 2026 through June 2029. This 32-month period will provide Google access to roughly 110,000 NVIDIA GPUs, along with supporting processors and memory. Capacity ramps up through September at a reduced fee, with termination options after the first year.
SpaceXA also established arrangements for computing power with Cursor, an AI coding startup. SpaceX acquired them in a $60 billion all-stock deal.
These arrangements position SpaceX’s collective position as an AI infrastructure powerhouse with high-margin revenue potential. The Google deal alone could generate nearly $29.5 billion over its term, while the Reflection contract adds another $6.3 billion.
Combined with the Anthropic arrangement, SpaceX stands to realize tens of billions in revenue from compute leasing in the coming years, which diversifies beyond SpaceX’s traditional rocket launches and Starlink operation.
The deals underscore growing demand for advanced AI training and inference capacity amid chip shortages and surging model development needs. Reflection, valued at $25 billion and focused on “American open intelligence” with government and national security ties, cited recent restrictions on closed models as validation for open-source approaches.
For SpaceX, the partnerships transform capital-intensive data centers into flexible revenue sources while supporting its broader AI ambitions after the company has gone public.
It is safe to say SpaceX won’t be going for electric rockets anytime soon.
In a characteristically blunt reply on X, SpaceX frontman Elon Musk stated, “Unfortunately, electric rockets are impossible,” following reports that MSCI had assigned SpaceX its lowest possible ESG rating of CCC.
The assessment, issued just this past week, coinciding closely with SpaceX’s public market debut, placed the company on par with nations like Russia in sustainability scoring and cited significant risks in environmental, social, and governance areas.
MSCI flagged SpaceX’s exposure to rocket emissions and other operational impacts, alongside governance concerns such as concentrated control by Musk and limited shareholder protections. Musk’s terse comment directly addressed the environmental pillar, underscoring a core physical constraint that ESG frameworks often overlook when evaluating high-thrust industries.
Unfortunately, electric rockets are impossible
— Elon Musk (@elonmusk) June 21, 2026
Electric propulsion systems do exist and are widely used in space. Ion thrusters and Hall-effect thrusters accelerate ionized propellant, typically xenon or krypton, using electric fields, achieving very high specific impulse, often exceeding 3,000 seconds compared to roughly 300–450 seconds for chemical rockets.
This efficiency makes them ideal for satellite station-keeping, orbit raising, and deep-space missions where low thrust over long durations is sufficient. SpaceX’s own Starlink satellites employ electric propulsion for these purposes.
However, launching from Earth’s surface demands something entirely different: enormous thrust delivered rapidly to overcome gravity and atmospheric drag. A typical orbital-class booster must generate thrust far exceeding its weight, often in the millions of Newtons within seconds.
Chemical rockets achieve this through exothermic combustion of dense propellants, producing high-mass-flow, high-velocity exhaust. Electric systems, by contrast, expel very small amounts of mass at extremely high speeds. Generating equivalent thrust would require impractical onboard power levels, massive energy storage or generation systems, and prohibitive added mass, rendering the approach infeasible with current or near-term technology.
Musk has previously expressed a similar sentiment, noting a desire for electric orbital rockets while acknowledging the inescapable requirements of Newton’s third law and energy delivery. The distinction is clear: electric propulsion excels once a vehicle is already in space; it cannot replace the high-thrust chemical phase required to reach orbit from the ground.
The episode illustrates broader critiques of ESG ratings. Proponents argue they incentivize better risk management and long-term sustainability. Detractors, including Musk—who has previously called ESG a “scam”—contend that such metrics can penalize essential activities when no practical alternative exists, potentially discouraging innovation in sectors like space access.

SpaceX has sought to mitigate launch-related impacts through reusability: Falcon 9 boosters have flown more than 30 times in some cases, dramatically lowering the manufacturing and emissions burden per kilogram delivered to orbit. Starship’s design further emphasizes rapid reusability and methane propellant, which can theoretically be produced via sustainable pathways.
Ultimately, Musk’s remark serves as a reminder that certain engineering realities persist regardless of scoring systems. As humanity expands its presence in space for communications, science, and exploration, balancing genuine environmental progress with technological necessity remains a central challenge.
ESG frameworks may evolve, but the fundamental limits of electric launch propulsion are unlikely to change soon.
