SpaceX considers Florida launch pad for both Falcon and Mars vehicle launches
Following a highly informative discussion at the ISS R&D conference, Elon Musk revealed that the updated, leaner version of SpaceX’s Mars architecture would likely have a diameter of around 9 meters.
A 9m Interplanetary Transport System, while precisely 25% smaller than the 12m diameter version revealed last year, would have to either lose the outer ring of full scale Raptor engines, or pivot to a smaller version of Raptor in order to preserve the 42 engine configuration shown at the IAC. Given Musk’s adamant and harsh judgement of the complexity of 27 Merlin 1D engines simultaneously firing on Falcon Heavy, moving to a 21 engine first stage for SpaceX’s Mars vehicle is a fair bet, so long as the full scale Raptor engine is still planned. Extremely speculative calculations based on the limited information available suggest that this smaller ITS could launch a bit less than half the payload of the original, still almost double the capability of Saturn V.

Possibly the most significant information to come out of this tweet is the implication that SpaceX and Musk are now looking to utilize current manufacturing facilities for the construction of a smaller ITS. While it adds considerable expense, the transport of a Space Shuttle’s external fuel tank through the streets of Los Angeles in 2011 sets a precedent for it being possible for SpaceX to transport a 9m vehicle from its factory in Hawthorne, CA to a nearby port. If SpaceX is able to use the same facilities it currently has for developing its Mars vehicle, it would experience immense savings compared to the cost of developing entirely new factories and testing facilities. This matches up perfectly with Musk’s repeated statement that the updated ITS is focused on improving the economic case for the vehicle and making it significantly cheaper to develop.

Possibly the most crucial keystone of this economical update relates to the launch pad or pads that will be necessary to launch a rocket as large as either ITS. An oft-overlooked feature of the current LC-39A launch pad SpaceX leases and operates in Florida is that it and its LC-39B sibling were developed with a far larger and more powerful version of Saturn V in mind, known as Nova at the time. SpaceX is well aware of this, and is also painfully aware of just how expensive the construction of launch pads can be after having to undertake deep repairs of LC-40.

With this arrangement, SpaceX would be able to continue crewed and Falcon Heavy launches from the pad while conducting initial tests and launches of their ITS.

Buried in a fascinating article by Chris Bergin of NASASpaceflight.com fame, Bergin has revealed that documents and rumblings behind the scenes indicate that SpaceX is seriously considering either co-launching from LC-39B or modifying LC-39A with a second launch mount. This would require considerably modifications to the venerable pad, but it would not require the costly and time-consuming construction of an entirely new launch pad. Speculative renders and mockups (above) created by the skilled forum members of NASASpaceflight demonstrate this nicely, showing the launch mount for ITS and Falcon side by side.
Combined with Musk’s past statements about this updated version of ITS, the future is looking increasingly bright for what was initially a somewhat crazy architecture. Easier transport, recycled development facilities, and co-location on an already-constructed launch pad show that SpaceX are completely serious about their ambitions for Mars and are willing to do what is necessary to get to the Moon, the Red Planet, and beyond.

Elon Musk’s X will start using a Tesla-like software update strategy
The initiative seems designed to accelerate updates to the social media platform, while maintaining maximum transparency.
Elon Musk’s social media platform X will adopt a Tesla-esque approach to software updates for its algorithm.
The initiative seems designed to accelerate updates to the social media platform, while maintaining maximum transparency.
X’s updates to its updates
As per Musk in a post on X, the social media company will be making a new algorithm to determine what organic and advertising posts are recommended to users. These updates would then be repeated every four weeks.
“We will make the new 𝕏 algorithm, including all code used to determine what organic and advertising posts are recommended to users, open source in 7 days. This will be repeated every 4 weeks, with comprehensive developer notes, to help you understand what changed,” Musk wrote in his post.
The initiative somewhat mirrors Tesla’s over-the-air update model, where vehicle software is regularly refined and pushed to users with detailed release notes. This should allow users to better understand the details of X’s every update and foster a healthy feedback loop for the social media platform.
xAI and X
X, formerly Twitter, has been acquired by Elon Musk’s artificial intelligence startup, xAI last year. Since then, xAI has seen a rapid rise in valuation. Following the company’s the company’s upsized $20 billion Series E funding round, estimates now suggest that xAI is worth tens about $230 to $235 billion. That’s several times larger than Tesla when Elon Musk received his controversial 2018 CEO Performance Award.
As per xAI, the Series E funding round attracted a diverse group of investors, including Valor Equity Partners, Stepstone Group, Fidelity Management & Research Company, Qatar Investment Authority, MGX, and Baron Capital Group, among others. Strategic partners NVIDIA and Cisco Investments also continued support for building the world’s largest GPU clusters.

Tesla FSD Supervised wins MotorTrend’s Best Driver Assistance Award
The decision marks a notable reversal for the publication from prior years, with judges citing major real-world improvements that pushed Tesla’s latest FSD software ahead of every competing ADAS system.
Tesla’s Full Self-Driving (Supervised) system has been named the best driver-assistance technology on the market, earning top honors at the 2026 MotorTrend Best Tech Awards.
The decision marks a notable reversal for the publication from prior years, with judges citing major real-world improvements that pushed Tesla’s latest FSD software ahead of every competing ADAS system. And it wasn’t even close.
MotorTrend reverses course
MotorTrend awarded Tesla FSD (Supervised) its 2026 Best Tech Driver Assistance title after extensive testing of the latest v14 software. The publication acknowledged that it had previously criticized earlier versions of FSD for erratic behavior and near-miss incidents, ultimately favoring rivals such as GM’s Super Cruise in earlier evaluations.
According to MotorTrend, the newest iteration of FSD resolved many of those shortcomings. Testers said v14 showed far smoother behavior in complex urban scenarios, including unprotected left turns, traffic circles, emergency vehicles, and dense city streets. While the system still requires constant driver supervision, judges concluded that no other advanced driver-assistance system currently matches its breadth of capability.
Unlike rival systems that rely on combinations of cameras, radar, lidar, and mapped highways, Tesla’s FSD operates using a camera-only approach and is capable of driving on city streets, rural roads, and freeways. MotorTrend stated that pure utility, the ability to handle nearly all road types, ultimately separated FSD from competitors like Ford BlueCruise, GM Super Cruise, and BMW’s Highway Assistant.
High cost and high capability
MotorTrend also addressed FSD’s pricing, which remains significantly higher than rival systems. Tesla currently charges $8,000 for a one-time purchase or $99 per month for a subscription, compared with far lower upfront and subscription costs from other automakers. The publication noted that the premium is justified given FSD’s unmatched scope and continuous software evolution.
Safety remained a central focus of the evaluation. While testers reported collision-free operation over thousands of miles, they noted ongoing concerns around FSD’s configurable driving modes, including options that allow aggressive driving and speeds beyond posted limits. MotorTrend emphasized that, like all Level 2 systems, FSD still depends on a fully attentive human driver at all times.
Despite those caveats, the publication concluded that Tesla’s rapid software progress fundamentally reshaped the competitive landscape. For drivers seeking the most capable hands-on driver-assistance system available today, MotorTrend concluded Tesla FSD (Supervised) now stands alone at the top.

Elon Musk’s Grokipedia surges to 5.6M articles, almost 79% of English Wikipedia
The explosive growth marks a major milestone for the AI-powered online encyclopedia, which was launched by Elon Musk’s xAI just months ago.
Elon Musk’s Grokipedia has grown to an impressive 5,615,201 articles as of today, closing in on 79% of the English Wikipedia’s current total of 7,119,376 articles.
The explosive growth marks a major milestone for the AI-powered online encyclopedia, which was launched by Elon Musk’s xAI just months ago. Needless to say, it would only be a matter of time before Grokipedia exceeds English Wikipedia in sheer volume.
Grokipedia’s rapid growth
xAI’s vision for Grokipedia emphasizes neutrality, while Grok’s reasoning capabilities allow for fast drafting and fact-checking. When Elon Musk announced the initiative in late September 2025, he noted that Grokipedia would be an improvement to Wikipedia because it would be designed to avoid bias.
At the time, Musk noted that Grokipedia “is a necessary step towards the xAI goal of understanding the Universe.”
Grokipedia was launched in late October, and while xAI was careful to list it only as Version 0.1 at the time, the online encyclopedia immediately earned praise. Wikipedia co-founder Larry Sanger highlighted the project’s innovative approach, noting how it leverages AI to fill knowledge gaps and enable rapid updates. Netizens also observed how Grokipedia tends to present articles in a more objective manner compared to Wikipedia, which is edited by humans.
Elon Musk’s ambitious plans
With 5,615,201 total articles, Grokipedia has now grown to almost 79% of English Wikipedia’s article base. This is incredibly quick, though Grokipedia remains text-only for now. xAI, for its part, has now updated the online encyclopedia’s iteration to v0.2.
Elon Musk has shared bold ideas for Grokipedia, including sending a record of the entire knowledge base to space as part of xAI’s mission to preserve and expand human understanding. At some point, Musk stated that Grokipedia will be renamed to Encyclopedia Galactica, and it will be sent to the cosmos.
“When Grokipedia is good enough (long way to go), we will change the name to Encyclopedia Galactica. It will be an open source distillation of all knowledge, including audio, images and video. Join xAI to help build the sci-fi version of the Library of Alexandria!” Musk wrote, adding in a later post that “Copies will be etched in stone and sent to the Moon, Mars and beyond. This time, it will not be lost.”
