SpaceX working on several Starship, Super Heavy upgrades and design changes
Not long after Elon Musk confirmed plans to add three more Raptor engines to Starship and stretch the upper stage’s propellant tanks, the SpaceX CEO has confirmed one of several smaller design changes planned in the interim.
On January 3rd, Musk confirmed that SpaceX is entirely relocating one of two secondary ‘header’ tanks that Starships use to store landing propellant. A graphic sketched on the side of future Starship rings further revealed plans to tweak most of the subsections that SpaceX stacks to form a Starship, complementing an upgraded nosecone design. Finally, another design change was spotted on hardware that will eventually become part of the first full-thrust Super Heavy booster.
According to Musk, starting with Starship 24 (S24), which is likely the next ship SpaceX will complete, the methane (fuel) header tank will be relocated from Starship’s common dome to its nosecone. From the start, Starship’s oxygen header tank has been located in the very tip of the nose – placed in such an inconvenient location for the sole purpose of shifting Starship’s center of gravity forward. Now, the methane header tank will join it in the nose, with the obvious explanation being a need to shift that center of gravity even further forward. It’s possible that this change was planned before SpaceX realized the performance benefits of a stretched, nine-engine Starship, but it could also be a preemptive modification meant to counteract the added weight of three more Raptor engines and longer tanks.
Musk’s confirmation of the methane header tank’s relocation came just a few days after a drawing on the side of a Starship section further confirmed several more minor design changes. Starbase ‘hieroglyphics’ are not uncommon, as SpaceX engineers and technicians have often used hardware itself as a sort of whiteboard to sketch out plans and literally annotate ongoing work. This particular drawing was exceptionally detailed and useful, effectively showing exactly how Starship’s design will change beginning with Ship 24. The changes are simple enough: in essence, SpaceX will be adding an extra ring to several Starship ‘sections.’ For current ships, six distinct sections are stacked to form the Starship’s cylindrical tankage and hull.
It takes another five stacked sections to complete the current nosecone design. Counting the nose as one, it takes about seven stack operations to fully assemble the basic structure of a Starship. With the design changes sketched out on a Starship S24 ring and an upgraded nosecone that will debut on the same ship, fully assembling a nosecone will now take two or three stacks (down from five) and fully assembling a Starship will take six stacks (down from seven). While obviously not a major redesign, the changes will significantly simplify (and thus potentially speed up) Starship assembly, which will have additional positive follow-on impacts on plumbing, wiring, and heat shield installation.
There’s good reason to believe that some of the changes – especially expanding Starship’s nose barrel from four to five rings tall – will end up being applied to Super Heavy, potentially reducing the number of booster ‘sections’ needed from nine to seven or eight. However, there are already signs of some weirder changes being made to Super Heavy’s design. On December 21st, a Super Heavy thrust dome – likely Booster 7’s – was sleeved with several steel rings as part of a now-routine process, partially completing the first 33-engine thrust section. However, instead of the usual aft barrel section comprised of three six-foot-tall (~1.82m) steel rings, this ‘sleeve’ was made up of four ~1.4m-tall rings – the first time in Starbase history that shorter rings have appeared on any hardware.
Unlike all the other changes described above, it’s entirely unclear what benefit SpaceX is getting from keeping a given ship or booster section the same height while adding more smaller rings to it – a process that will inherently increase the complexity and amount of work required to complete that section. Regardless, it’s clear that SpaceX is in the midst of a significant period of design revision that could see Ship 24 and Booster 7 debut with a wide range of upgrades and design changes in just a few months.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.
Roadster event update
We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.

Elon Musk and Trump are closer than ever, and Tesla could be the big winner
Elon Musk sat beside Trump as AI leaders signed a voluntary White House safety accord.
Elon Musk had the seat right next to President Donald Trump on Tuesday as the White House hosted the leaders of America’s biggest artificial intelligence companies for a lunch that ended with a voluntary industry accord on AI safety.
A seating chart Trump posted on Truth Social placed Musk at the president’s left in the East Room, with Nvidia CEO Jensen Huang on his right, according to an Associated Press reporter. Anthropic CEO Dario Amodei, OpenAI President Greg Brockman, Meta’s Mark Zuckerberg, Google’s Sundar Pichai, Microsoft’s Satya Nadella and Amazon founder Jeff Bezos also attended, along with Vice President JD Vance and House Speaker Mike Johnson.

After the lunch, Trump told reporters outside the West Wing that the executives had signed “The White House Accord on Superintelligence: A Joint Commitment on Frontier SI Responsibilities.” Johnson described it as a voluntary statement of principles built on “robust internal controls and layers of internal and external review,” while Zuckerberg said company boards would independently review reports from outside auditors. Trump called the document “morally binding,” said he would name a new AI czar within days, and signed an executive order formally renaming artificial intelligence “super intelligence,” CNBC reported.
Musk was not in the room for Tesla alone. Since SpaceX absorbed xAI, he runs the company behind Grok and one of the largest AI training operations anywhere. On September 25, he said another 220,000 Nvidia GB300 chips would come online at Colossus 2 within a week, with more expected in November and December.

Musk also used the trip to restate his energy ambitions. “SpaceX is aiming together with Tesla to do 200 gigawatts of solar production per year,” he said at an event in Washington. It is the same combined target he laid out that feeds directly into Terafab, the Tesla and SpaceX chip venture that will need enormous amounts of power.
The showing between Musk and Trump has come a long way, since the two had the very public split in mid 2025 after Musk opposed the “Big Beautiful Bill” and left DOGE. They reconciled at Charlie Kirk’s memorial that September, and Trump later called their relationship “good”. Since then, Musk has joined Trump’s China delegation in May and attended last week’s White House state dinner for Chinese President Xi Jinping.
For Tesla, that access to government official could pay dividends. As Teslarati noted in January, federal autonomy rules, NHTSA oversight and a single national standard for driverless vehicles all run through an administration Musk can more easily reach directly as Tesla works to scale Robotaxi and Cybercab beyond Texas.
