SpaceX may have signed a fairing agreement with ULA supplier RUAG (Update: no agreement)
According to unverified and speculative comments reportedly made to a member of the space industry by a RUAG spokesperson, the prominent aerospace supplier may have reached an agreement with SpaceX to manufacture a handful of larger payload fairings for future Falcon 9 and Heavy launches.
In the likely event that SpaceX is one of two contractors awarded a portion of several dozen US military launch contracts next year, the company will need to be able to cater to niche requirements, including accommodating unusually tall military satellites. Those satellites can be so tall that SpaceX’s own payload fairing – generally middle-of-the-pack relative to competitors’ offerings – may be too short, meaning that SpaceX will have to find ways around that minor shortcoming.
Update: Tim Chen has retracted his earlier comments and has stated that there is actually no agreement currently in place with SpaceX for RUAG to produce taller fairings out of its new Decatur, AL factory.
Additionally, ULA CEO Tory Bruno clarified that the company’s “[new fairing] has [ULA] intellectual property in its design and manufacture … [and] is currently planned only for use on Atlas and Vulcan”, meaning that any cooperation between SpaceX and RUAG would likely require a new production facility and a somewhat different fairing design.
“ULA’s new fairing, which is built in our factory in Decatur, has our intellectual property in its design and manufacture. This fairing is currently planned only for use on Atlas and Vulcan. You would want to ask RUAG about business they might have with their other customers.”

Regardless of the veracity of these recent claims, it appears that SpaceX has three obvious responses at its disposal: design and build an entirely new variant of its universal Falcon fairing, purchase the necessary fairings from an established supplier, or bow out of launch contract competitions that demand it. The latter option is immediately untenable given that it could very well mean bowing out of the entire US military competition, known as Phase 2 of the National Security Space Launch program’s (NSSL; formerly EELV) Launch Services Procurement (LSP).
For dubious reasons, the US Air Force (USAF) has structured the NSSL Phase 2 acquisition in such a way that – despite there being four possible competitors – only two will be awarded contracts at its conclusion. The roughly ~30 launch contracts up for grabs would be split 60:40 between the two victors, leaving two competitors completely emptyhanded. In short, bowing out of the Phase 2 competition could mean forgoing as many as one or two-dozen contracts worth at least $1-2B, depending on the side of the 60:40 split.
According to a handful of recent comments and developments, SpaceX has likely sided with the option of procuring taller fairings from an industry supplier. As it turns out, European company RUAG has effectively cornered the Western rocket fairing market, with SpaceX being the only Western launch company currently building its own fairings. RUAG builds fairings for both Arianespace’s Ariane 5 and Vega rockets and ULA’s Atlas V. Additionally, RUAG will build and supply fairings for both companies’ next-gen rockets – Arianespace’s Ariane 6 and ULA’s Vulcan – and builds fairings for a number of smallsat launch companies.
Comments made in June by a RUAG official confirmed that there was some semblance of a relationship between SpaceX and RUAG for the purpose of satisfying USAF needs for taller fairings, although the phrasing suggested that the cooperation was in its early stages and nothing had been solidified.
“In a June 12 letter to Smith, the company’s CEO Peter Guggenbach makes the case that legislation forcing access to suppliers is unnecessary in this case because RUAG does not have an exclusive arrangement with ULA and is willing to work with SpaceX or any other launch providers.
“For this competition, we are in the process of submitting or have submitted proposals to multiple prime contractors regarding launch vehicle fairings. In those agreements, we share technical data to support a prime contractor’s bid while protecting our intellectual property.”
RUAG vice president Karl Jensen told SpaceNews the company has a “significant partnership” with ULA but is looking to work with others too. “We have an offer to SpaceX,” he said. “We don’t know if they’ll accept it.”

Interestingly, although ULA’s RUAG-built Atlas V fairing is slightly narrower than SpaceX’s 5.2m (17 ft) diameter fairing, Atlas V’s largest fairing is significantly taller, supporting payloads up to 16.5m (54 ft) tall compared to 11m (36 ft) for Falcon 9 and Heavy. Given that just a tiny portion of military spacecraft actually need fairings that tall, SpaceX is apparently not interested in simply modifying its own fairing design and production equipment to support a 20-30% stretch.
This likely relates in part to the fact that one of SpaceX’s three NSSL Phase 2 competitors – Northrop Grumman (Omega), Blue Origin (New Glenn), and ULA (Vulcan) – are guaranteed to receive hundreds of millions of dollars of development funding after winning one of the two available slots (60% or 40% of contracts). SpaceX, on the other hand, will receive no such funding while still having to meet the same stringent USAF requirements compete in LSP Phase 2. Of note, Congressman Adam Smith managed to insert a clause into FY2020’s defense authorization bill that could disburse up to $500M to SpaceX in the event that the company is one of Phase 2’s two winners.
Despite this potential influx of infrastructure-focused funds, SpaceX may still be pursuing taller Falcon fairings from RUAG as a backup in the event that the company is not one of the two Phase 2 winners or is unable to use some of the $500M secured by Rep. Smith to develop its own stretched fairing.
On August 12th, SpaceX – along with Blue Origin, ULA, and NGIS – submitted bids for NSSL Phase 2 launch services, confirming that all four companies will indeed be in the running for contracts. The USAF is not expected to announce the results of this competition until Q2 2020.

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.”
