SpaceX fully installs Super Heavy booster’s ‘aerocovers’
For the first time, SpaceX has more or less installed a full set of ‘aerocovers’ on a Super Heavy booster prototype.
Designed to protect the booster from both itself and Earth’s atmosphere during ground testing, liftoff, ascent, and reentry, Super Heavy’s the structures amount to thin, steel shells mounted on metal box frames. The most obvious aerocovers slot over the top of six racks of equipment installed on the outside of Super Heavy’s aft end, giving the booster a sort of utility belt of hydraulic systems, pressure vessels, avionics, and heat exchangers. Unsurprisingly, those racks are festooned with electronics, composites, and thousands of feet of wiring and thin plumbing – none of which are particularly suited to sit a few dozen feet from the fury of 29-33 Raptor engines or near the leading edge of a hypersonic reentry vehicle.
Aside from the steel they’re mounted on, it’s likely that every system located on Super Heavy’s ‘utility built’ would begin malfunctioning or be destroyed outright if directly exposed to just a few seconds of the hypersonic buffeting and heating Starship boosters will experience during reentry. Unlike Falcon boosters, which almost always use reentry burns to slow down and create a sort of heat shield with their own exhaust, SpaceX is theoretically designing Super Heavy to survive the full force of reentry without an extra burn to cushion the blow.
To survive reentry and still land in good enough condition to enable anything close to same-day reusability, which is SpaceX’s goal, every ounce of at-risk equipment installed on Super Heavy’s exterior will likely need to be carefully shielded. In theory, that’s the purpose of the aerocovers SpaceX has only just begun to fully install – let alone test – on Super Heavy B4.
Before Booster 4’s most recent installation on the orbital launch mount, SpaceX did install covers over a pair of hydraulic and heat exchanger racks but left all four composite overwrapped pressure vessel (COPV) racks and an umbilical port uncovered. After B4 was removed from the launch mount for the third time on December 30th, both covers were uninstalled. On January 14th, 2022, though, SpaceX rapidly installed all six covers for the first time and began sealing each cover’s exposed corners. On January 17th, SpaceX even installed aerodynamic surfaces around Booster 4’s protruding umbilical port, smoothing out any hypothetical airflow around the device.
Prior to main aerocover installation, SpaceX also added at least half a dozen small boxes seemingly designed to protect a number of thin metal probes that pierce through Super Heavy’s tanks and skin and are connected to avionics boxes. Additionally, while less visible, teams also worked to finish Super Heavy B4’s Raptor heat shielding with a large number of similar sheet steel covers and panels. Without official photos from SpaceX or another lift onto the launch mount, it’s impossible to know if Booster 4’s Raptor heat shield is fully closed out, but the shielding that runs around its circumference appears to be finished.
As it stands, Super Heavy B4 is likely just a few parts shy of true completion and is about as ready as it’ll ever be for static fire testing. More likely than not, those aerocovers and Raptor heat shields are essential for Super Heavy B4 to be able to perform more than one test at a time without immediately requiring major repairs. Unlike Starship, which has mostly tested three engines at once and only performed a few six-engine static fires, Super Heavy B4 may eventually test all 29 Raptor engines simultaneously.
When almost 30 engines are involved, even nominal preburner testing will likely produce a massive fireball that could engulf Super Heavy’s aft (if not the entire booster) with flames. For static fire testing, Raptors typically produce a smaller and briefer (but still substantial) fireball during shutdown, creating another potential source of damage to any sensitive hardware located anywhere on or in Booster 4’s thrust section. As such, Super Heavy aerocovers may be just as important for surviving static fires as they’ll be for surviving launches and landings.
It’s unclear if or when Super Heavy B4 will return to the orbital launch mount for wet dress rehearsal and static fire testing. SpaceX has ambiguous test windows scheduled from 10am to 10pm on January 18th, 19th, and 20th.
Elon Musk posted a candid admission on his social media platform X on June 9, declaring that he had been “clearly wrong” about Anthropic. The statement marked a notable reversal from his earlier skepticism toward the AI company.
In September, Musk had written, “Winning was never in the set of possible outcomes for Anthropic,” reflecting his view at the time that the startup had lacked the foundation or even the trajectory to succeed in what is an incredibly intense race for advanced artificial intelligence.
Musk’s latest post came amid discussion of Anthropic’s reliance on external compute resources. He praised the company’s progress, stating that Anthropic is “obviously currently the leader in AI” and that “no company has released a model as good as Mythos/Fable,” with expectations of a strong follow-up in Mythos 2.
The tone shifted dramatically from dismissal to acknowledgement of superior performance.
I was clearly wrong about Anthropic. They are obviously currently the leader in AI. No company has released a model as good as Mythos/Fable and they will undoubtedly have Mythos 2 ready soon.
And I would never cut them off in a way that hurt them badly, even as a competitor.…

The context of Musk’s comments added significance. Anthropic has been operating under a recent compute deal with SpaceXAI, Musk’s AI infrastructure-focused venture. The pair entered a short-term GPU lease agreement initiated in May, providing Anthropic access to critical computing power for training and deploying its frontier models.

Some observers had speculated that Musk could leverage this dependency to disadvantage a rival. Musk directly addressed the possibility, writing, “I would never cut them off in a way that hurt them badly, even as a competitor. That’s not my style.”
To support his commitment to ethical competition, Musk referenced concrete examples from his other companies. Tesla famously open-sourced its entire portfolio of electric vehicle patents in 2014. The move was designed to accelerate the global adoption of sustainable transportation technology rather than protect proprietary advantages.
Tesla also made its Supercharger network available to competing electric vehicle manufacturers, transforming what could have remained an exclusive charging ecosystem into a shared infrastructure that benefits the broader industry and reduces barriers for EV adoption.
Musk further pointed to SpaceX’s practices, noting that the company launches satellites for competing commercial systems “with no increase in price or use of unfair terms.” He extended the principle to his social platform, observing that “even my worst enemies attack me on this platform,” underscoring preference for open discourse over retaliation.
These examples have illustrated Musk’s long-standing philosophy that long-term technological progress is best served by open competition and infrastructure sharing rather than leveraging market power to stifle rivals. In the fast-evolving AI sector, where compute resources and model capabilities determine leadership, Musk’s stance suggests a willingness to compete on innovation and performance alone.
Musk’s admission arrives as SpaceXAI itself advances its own frontier models while maintaining business relationships across the ecosystem. By publicly correcting his earlier assessment and reaffirming principles of fair play, Musk highlights a model of competition that prioritizes advancement of the field over short-term tactical advantages.

NASA taps SpaceX to launch the telescope that could unlock new worlds
NASA’s Roman Space Telescope heads to orbit this August aboard SpaceX’s Falcon Heavy with massive scientific ambitions.
SpaceX is set to play a central role in one of NASA’s most anticipated science missions in years. The company’s Falcon Heavy rocket, currently the most powerful operational launch vehicle in the world, will carry the Nancy Grace Roman Space Telescope into orbit on August 30 from Kennedy Space Center in Florida. Roman is now in final preparations inside the Payload Hazardous Servicing Facility, where on June 26 technicians used a crane to lift the observatory into a specialized stand for fueling and pre-launch testing.
Roman is named after Nancy Grace Roman, NASA’s first chief of astronomy, whose career helped shape how the agency approaches space science.
NASA chose SpaceX Falcon Heavy because of Roman’s needs to reach a specific orbit far from Earth, well beyond where a standard Falcon 9 can deliver it. The Falcon Heavy, which first flew in 2018, has since become NASA’s go-to option for missions that need serious muscle without the cost and complexity of older launch systems.

Roman will carry a field of view at least 100 times wider than the Hubble Space Telescope, meaning it can photograph enormous swaths of the universe in a single shot rather than the narrow slices Hubble captures. That difference in scale is significant. While Hubble reshaped our understanding of the cosmos over 30 years, Roman is built to work faster and wider, surveying hundreds of millions of galaxies at once.
One of Roman’s most compelling capabilities is its potential to discover and photograph planets orbiting stars outside our solar system, and with enough precision to directly image planets that would otherwise be lost. That means scientists could study the atmosphere and surface characteristics of distant worlds rather than simply confirming they exist. Combined with Roman’s sweeping field of view, the telescope could detect thousands of exoplanets, and some of those planets may be in habitable zones where liquid water could exist. No telescope currently in operation has this level of power and capability. That capability alone could change what we know about other worlds, and perhaps finally answer the question: are we the only intelligent lifeforms in existence?
What Roman actually finds once it reaches orbit is an open question, and that is exactly what makes this launch worth watching.

SpaceX’s newest logo confirms everything about what it’s become
SpaceX officially absorbed xAI under the SpaceXAI brand, completing the largest private merger in history.
SpaceX made its corporate transformation official in May 2026 when Elon Musk posted on X that xAI would cease to exist as a standalone company. “xAI will be dissolved as a separate company, so it will just be SpaceXAI, the AI products from SpaceX,” he wrote.
A new SpaceXAI logo was announced today, visually embedding the xAI letters inside the SpaceX identity, which can be seen as a deliberate design choice that signals the merger is not a partnership but a full absorption and XAi a core function of the same company. The same way Starlink is not a separate brand but a SpaceX product. The announcement closed the loop on a process that began February 2, 2026, when SpaceX acquired xAI in the largest private merger in history, valued at $1.25 trillion. SpaceX at $1 trillion and xAI at $250 billion.

The reason SpaceX bought xAI was stated plainly by Musk at the time of the deal: to build orbital data centers. SpaceX had simultaneously filed with the FCC to launch up to one million satellites designed to function as AI compute nodes in low Earth orbit, escaping what Musk described as the energy constraints limiting AI development on Earth.
xAI provided the AI software stack, with Grok, the X platform, and the Colossus supercomputer infrastructure in Memphis with over 220,000 NVIDIA GPUs, while SpaceX provided the rockets, Starlink, and the capital base to fund it. The two companies needed each other. xAI was burning $2.5 billion in losses on $250 million in revenue. SpaceX was generating an estimated $8 billion in profit on $15 billion in revenue and needed an AI narrative to command the valuation it was targeting for its IPO.
What SpaceX has done, regardless of how the orbital AI vision ultimately plays out, is walk into a public market as something no company has been before: a rocket manufacturer, satellite internet provider, AI software company, social media platform, and supercomputer operator under one ticker. Whether that combination is worth $2 trillion depends entirely on which of those businesses you believe in most.
