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 bull sees odds rising of Tesla merger after Musk confirms SpaceX-xAI deal
Dan Ives of Wedbush Securities wrote on Tuesday that there is a growing chance Tesla could be merged in some form with SpaceX and xAI over the next 12 to 18 months.
A prominent Tesla (NASDAQ:TSLA) bull has stated that the odds are rising that Tesla could eventually merge with SpaceX and xAI, following Elon Musk’s confirmation that the private space company has combined with his artificial intelligence startup.
Dan Ives of Wedbush Securities wrote on Tuesday that there is a growing chance Tesla could be merged in some form with SpaceX and xAI over the next 12 to 18 months.
“In our view there is a growing chance that Tesla will eventually be merged in some form into SpaceX/xAI over time. The view is this growing AI ecosystem will focus on Space and Earth together…..and Musk will look to combine forces,” Ives wrote in a post on X.
Ives’ comments followed confirmation from Elon Musk late Monday that SpaceX has merged with xAI. Musk stated that the merger creates a vertically integrated platform that combines AI, rockets, satellite internet, communications, and real-time data.
In a post on SpaceX’s official website, Elon Musk added that the combined company is aimed at enabling space-based AI compute, stating that within two to three years, space could become the lowest-cost environment for generating AI processing power. The transaction reportedly values the combined SpaceX-xAI entity at roughly $1.25 trillion.
Tesla, for its part, has already increased its exposure to xAI, announcing a $2 billion investment in the startup last week in its Q4 and FY 2025 update letter.
While merger speculation has intensified, notable complications could emerge if SpaceX/xAI does merge with Tesla, as noted in a report from Investors Business Daily.
SpaceX holds major U.S. government contracts, including with the Department of Defense and NASA, and xAI’s Grok is being used by the U.S. Department of War. Tesla, for its part, maintains extensive operations in China through Gigafactory Shanghai and its Megapack facility.

Musk donates generators
As noted in a report from WSMV4, the historic storm that hit Tennessee resulted in hundreds of thousands of residents experiencing a power outage at the end of January. Thousands are still living without power or heat in freezing temperatures for up to nine days.
As per TN Gov. Bill Lee in a post on X, Elon Musk and xAI have donated hundreds of generators to assist residents in affected areas. “Tennesseans without power need immediate help. I’m deeply grateful to @elonmusk & @xAI for going above & beyond to support Tennesseans by donating hundreds of generators to fill the gap, & I value their continued partnership to solve problems & support communities across our state,” he wrote in his post.
Tennessee officials have stated that recovery efforts remain ongoing as crews work to restore power and address damage caused by the winter storm. The generators are expected to provide temporary relief for residents facing power outages during freezing conditions.
Tesla Powerwalls may follow
Musk publicly responded to the governor’s post while hinting that additional help may be on the way. This time, the additional support would be coming from Musk’s electric vehicle company, Tesla.
“You’re most welcome. We’re working on providing Tesla Powerwalls too,” Musk wrote in his response to the official.
Even before Elon Musk’s comment, Tesla had already extended help to affected customers in Mississippi and Tennessee. In a post on X, the official Tesla Charging account noted that all Superchargers in the two states are online, and free Supercharging has been enabled to help those in areas that are affected by persistent power outages.
These include Grenada, Tupelo, Corinth, Southhaven, and Horn Lake in Mississippi and several Supercharging sites in Memphis, Tennessee.

Tesla-inspired door handles prohibited under China’s new safety standard
The rule effectively ends a design trend pioneered by Tesla and widely adopted across China’s electric vehicle market.
China will ban hidden door handles on electric vehicles starting 2027 under a new national safety standard, forcing automakers to equip their cars with mechanical exterior and interior handles.
The rule effectively ends a design trend pioneered by Tesla and widely adopted across China’s electric vehicle market.
China bans hidden door handles
China’s Ministry of Industry and Information Technology (MIIT) noted that the new mandatory national auto safety standard on EV door handles will take effect on January 1, 2027. For models that have already received approval and are scheduled for launch, automakers will be allowed to complete required design changes by January 2029.
Under the new rules, exterior door handles must remain operable even in scenarios involving irreversible restraint system failures or thermal runaway incidents in the battery pack. Doors must also be capable of opening even if the vehicle loses electrical power. Interior doors must include at least one independent mechanical release handle per door as well.
Safety concerns drive rollback
Hidden and electrically actuated door handles have become mainstream in recent years as EV makers pursued cleaner styling and improved aerodynamics. Tesla pioneered the hidden handle design, and it was adopted by most Chinese EV manufacturers in either fully hidden or semi-hidden forms, as noted in a CNEV Post report. Today, about 60% of top-selling EVs in China use the design.
Chinese regulators have stated that the designs pose safety risks, particularly in crashes or power failures where doors may not open from the inside or outside. Authorities cited multiple fatal incidents in which occupants or rescuers were unable to open vehicle doors after collisions.
One high-profile case occurred last October, when a Xiaomi SU7, a vehicle designed to be a competitor to the Tesla Model 3, caught fire following a crash in Chengdu in southwest China. The driver died after bystanders were unable to open the doors. The incident sparked intense scrutiny over the SU7’s Tesla-inspired door handles.
