SpaceX Starbase construction takes priority as next orbital Starship, Super Heavy pair come together
As SpaceX teams slowly prepare the first orbital-class Starship and Super Heavy booster for the next-generation rocket’s first full-stack launch, the company has simultaneously begun assembling a second ship/booster pair. However, it’s clear that orbital pad construction remains a priority.
Known as Ship 20 and Booster 4, the two stages of the first orbital-class Starship first arrived at the launch site in early August. Only eight weeks later has Starship S20 finally become the first of the pair to attempt and complete one of two crucial proof tests, opening the door for one or several Raptor static fires in the coming week or two. Meanwhile, Booster 4 has had all 29 of its Raptor engines installed, uninstalled, and reinstalled and twice been placed on and removed from Starbase’s orbital launch mount in the same time frame but has yet to attempt any proof testing.
Despite the apparent delays and challenges slowing Ship 20 and Booster 4’s test debuts and two plodding FAA reviews that appear all but guaranteed to preclude an orbital launch attempt in 2021, though, SpaceX has recently begun assembling a second two-stage Starship.
Save for Starhopper back in 2019, no Starship or Super Heavy prototype has spent nearly as long at the launch site without a single test as Ship 20 and Booster 4 have. To an extent, there have likely been some technical delays while assembling, outfitting, and working with two first-of-their-kind prototypes. Still, the difference between past vehicles like Starship SN15 and Super Heavy Booster 3 are so stark that some portion of the testing delays almost has to be a conscious decision made by SpaceX.
To be able to fully proof and static fire test Super Heavy B4, SpaceX first needs to plumb, wire, and outfit Starbase’s orbital launch mount and complete a majority of the orbital pad’s massive tank farm. However, the orbital pad and its many unfinished systems are situated just a thousand (~300m) east of the suborbital launch site and Starship test facilities, which are complete and ready for testing. To test a Starship at those facilities, SpaceX has to entirely clear the pad of personnel – now several hundred people at the peak of construction – for 6-12+ hours.
The implication is that SpaceX management effectively chose to rip off the bandage now rather than later, sacrificing timely testing of Starship S20 to allow a near-total focus on orbital pad construction and activation over the last ~8 weeks. It’s hard to say if that’s paid off but the fact that SpaceX has chosen this particular moment to begin assembling the next orbital-class Starship and Super Heavy suggests that a clearer plan is starting to come together.
B4/S20, meet B5/S21
Parts of Starship S21 and Super Heavy B5 have been floating around Starbase’s build site for weeks. There was a multi-week period, for example, where the site’s massive high bay was effectively unused – clearly a conscious choice given SpaceX’s history of Starship prototype production earlier this year and late last. Parts of Super Heavy B5 were likely ready for assembly (i.e. stacking) by mid to late August. The ‘mid bay’ used for Starship tank section assembly has been similarly underutilized for even longer – only recently accepting its first Starship S21 section after supporting assembly of the orbital pad’s final storage tank.
Instead, Booster 5 stacking began around September 15th. At the current rate of assembly, which has slowed down considerably in the last week, SpaceX’s second flightworthy Super Heavy could reach its full 69m (~225 ft) height as early as mid-October. Starship S20 likely won’t be far behind. Further, thanks to SpaceX’s preferred style of continuous improvement, Booster 5 and Ship 21 production already appear well on track to outpace Booster 4 and Ship 20. With B5, rather than installing a range of external equipment (avionics, wiring, plumbing) after assembly is finished, SpaceX appears to be completing some of those subsystems during stacking, potentially speeding up final assembly by 1-2+ weeks. With S21, SpaceX has begun outfitting the Starship’s nose cone with heat shield tiles far earlier in the assembly process than it did with S20.
Given that it has taken SpaceX the better part of a month to finish and spot-fix Starship S20’s heat shield since the prototype’s second trip to the test site, taking those lessons learned to heart and getting Starship S21’s heat shield installation right on the first try could cut weeks from final assembly.
In the meantime, after completing Ship 20’s first cryoproof test on September 29th, SpaceX will hopefully be able to kick off the first six-engine Raptor static fire test campaign within the next week or so. With any luck, the start of B5/S21 assembly also means that the orbital launch pad is nearly ready to support Super Heavy B4’s first proof tests, even if static fires with anything close to a full set of 29 Raptors appear to be weeks away. Regardless, it looks like it won’t be long before SpaceX will be juggling two pairs of orbital-class Starships and Super Heavy boosters.
Tesla Senior Vice President for Automotive Tom Zhu, a key executive behind the company’s success in China and Giga Texas, recently highlighted the “prime directive” of Full Self-Driving (FSD).
Zhu’s comments emphasize Tesla’s uncompromising focus on safety, which has made the company’s vehicles among the safest on the road.
Echoing Musk’s vision for safe autonomous driving
Zhu’s post quoted Musk’s statement from 2021, where the CEO reportedly stated that FSD must avoid accidents even if the most ridiculous events happened in the middle of the road. Zhu stated that beyond everything, Tesla’s systems like Autopilot and FSD are designed to keep passengers safe.
“Elon said it in 2021: “For self-driving, even if the road is painted completely wrong and a UFO lands in the middle of the road, the car still cannot crash and still needs to do the right thing. The prime directive for the autopilot system is: Don’t crash. That really overrides everything. No matter what the lines say or how the road is done, the thing that needs to happen is minimizing the probability of impact while getting you to your destination conveniently and comfortably,” Zhu stated.
“The prime directive, the absolute priority, is to minimize the probability of injury to yourself or to anyone on the road, to pedestrians, or anything like that. It can’t be dependent on the road markings being correct.”
Tesla leadership rallies behind global FSD rollout
Tom Zhu, who previously led Tesla China through its record-breaking growth phase, now oversees automotive operations worldwide. He has reportedly become a problem solver for Elon Musk over the years, with previous reports stating that he was brought in to help Giga Texas optimize its vehicle production ramp.
Zhu’s comments may sound ambitious, but FSD has proven that it values safety above all else over the years. This was highlighted recently in an incident in Australia, when a Model Y was hit by what could very well be a meteor. Despite the impact and part of its windshield melting, the vehicle was able to drive safely and keep its passengers safe.

Elon Musk’s biggest tech rival just canceled his Tesla Roadster
“I really was excited for the car! And I understand delays. But 7.5 years has felt like a long time to wait,” Altman said.
Elon Musk’s biggest tech rival just canceled his reservation for a Tesla Roadster, the supercar the company has been developing for nearly eight years.
Sam Altman, the CEO of OpenAI, announced on X on Thursday evening that he canceled his Tesla Roadster reservation, or at least is trying to:

Altman placed his Tesla Roadster reservation with a $50,000 deposit way back on July 11, 2018. However, he recently decided that he had waited long enough and decided to email the company to officially cancel the order.
“Hi, I’d like to cancel my reservation. Could you please refund me the $50k?” Altman emails to reservations@tesla.com.
He then received an immediate response, but not from Tesla. Instead, it was a bounce-back message from Google, stating that the message could not be delivered to the email because it was not active.
Altman then provided a reason for his cancellation, and it was not related to the intense rivalry he had with Elon Musk:
“I really was excited for the car! And I understand delays. But 7.5 years has felt like a long time to wait.”

Altman and Musk have a lengthy history with one another that dates back to 2015, when OpenAI was created. The feud has resulted in lawsuits over breaching founding agreements by prioritizing profits.
Musk has been especially critical in recent years because of Altman’s decision to turn OpenAI into a for-profit business that he says is “built on a lie.”
This year, Musk offered over $97 billion to buy OpenAI, and a judge blocked his request to stop the company from being converted into a for-profit in March.
OpenAI then countersued Musk in April, while xAI, Musk’s company, sued OpenAI for allegedly stealing secrets through poached employees in September.

Regarding the Roadster, Tesla has been developing it for several years and has delayed its release for five consecutive years. The company says it will have a demo of what it has changed since it was unveiled in 2017 later this year, but no date has been set quite yet.

Neuralink’s first human patient reflects on 21 months with brain implant “Eve”
He credited Neuralink and Elon Musk for giving him “the opportunity to be the first,” as the experience has been life-changing.
Nolan Arbaugh, the first person to receive Neuralink’s brain implant, shared his 21-month update this week, reflecting on how far he’s come since his groundbreaking surgery.
Arbaugh, who became paralyzed after a diving accident, stated that his Neuralink implant, which he fondly calls “Eve,” continues to transform his daily life.
Arbaugh celebrates Neuralink’s progress
In his post on X, Arbaugh revealed that his hands-on involvement with Neuralink has decreased as more participants have joined the program. “The team might call me to test something once in a blue moon,” he wrote, adding that he’s happy to see others experience the technology’s full potential, from operating robotic arms to typing on keyboards with thought alone.
He credited Neuralink and Elon Musk for giving him “the opportunity to be the first,” as the experience has been life-changing. Despite a recent pressure sore that temporarily kept him bedridden, Arbaugh noted that he is still very optimistic, describing his journey as one of resilience, faith, and gratitude. He also teased “big news” coming for his two-year update in early 2026.
Studies and a growing public speaking career
These days, Arbaugh stated that he is focused on his studies in neuroscience, taking full-semester courses in chemistry, biology, and pre-calculus while earning top grades. He credited “Eve” for making school possible again, as his current academic workload would have been “impossible without Neuralink.” Arbaugh stated that he has also begun building a speaking business after delivering a paid talk at Fortune’s Brainstorm Tech conference.
“At the beginning of September I attended the Fortune Brainstorm Tech conference in Park City, Utah, as a paid speaker. That sentence seemed like an impossibility two years ago. But it’s just the beginning. My business is built, my legal is near complete, I’m surrounding myself with a team of amazing folks, and I plan on speaking once or twice a month in the same fashion beginning as soon as January.
“Conferences, interviews, podcasts—you name it, and I want to be there spreading the word about how amazing this technology is, the growth it’s experiencing, the possibilities of the future, and how it has so deeply affected my life,” Arbaugh stated.
