SpaceX Starlink launch suffers last-second scrub, ULA up next [update: double scrub]

Update: ULA has scrubbed today’s NROL-44 launch attempt after the weather at the launch site substantially worsened. The Delta IV Heavy rocket’s next shot at launch is now scheduled no earlier than 11:58 pm EDT (03:58 UTC), Tuesday, September 29th, just two hours after a SpaceX Falcon 9 is scheduled to launch the US military’s fourth upgraded GPS III satellite.

SpaceX’s eleventh Starlink launch of the year was scrubbed ~30 seconds before liftoff by bad weather, likely delaying the mission a few days and leaving ULA’s latest Delta IV Heavy launch attempt next in line.

Scheduled to lift off at 10:22 am EDT on Monday, September 28th, SpaceX’s 12th operational Starlink launch (V1 L12) nearly made it to liftoff before the company called the mission off, prioritizing mission success above all else. Given that SpaceX’s Starlink program puts the company in the unique position of being its own launch customer, the decision to let a relatively mild weather violation delay a Starlink mission by at least a few days is unintuitively encouraging.

It’s no secret that SpaceX has become the most successful private launch company in history and a commercial force to be reckoned with, handily overtaking United Launch Alliance (ULA) and Arianespace to acquire a vast majority of the commercial launch market share. Falcon 9 is on track to become the fastest commercial rocket in history to cross the 100-launch milestone and SpaceX is already well on its way to regularly out-launching entire countries with 20+ missions per year. The single biggest risk facing the company is arguably complacency and an infamous tendency known as “launch fever.”

At the cutting edge of spaceflight, constant, exhaustive vigilance is ultimately the only thing standing between a reliable rocket or spacecraft and catastrophic failure. Perhaps the single biggest threat to that vigilance is the somewhat understandable desire to avoid launch delays – a fact of life for rocketry that nevertheless costs time, money, and (to some) reputation. The term “launch” or “go fever” was originally colloquialized to describe the irresponsible managerial pressure to launch largely responsible for both of NASA’s catastrophic Space Shuttle failures.

Some (if not most) parts of SpaceX almost assuredly would rather avoid launch delays. The fact that the company continues to accept Starlink launch delays and respect Falcon 9’s limits strongly implies that SpaceX has found ways to prevent launch fever while still pushing the envelope of launch cadence and rocket reuse. Starlink-12, for example, was originally meant to launch on September 17th but was delayed ~10 days by strong ocean currents before being scrubbed seconds before launch on September 28th. Combined with the fact that SpaceX is technically free to accept more risk on its own Starlink launches, compounded delays will inevitably test the limits of any organization’s resolve.

While the argument that SpaceX is technically the only direct stakeholder in Starlink missions is a bad-faith argument that could easily be made to push for increased risk tolerance, it’s only true in a vacuum. A Falcon 9 failure during a Starlink launch would still have major consequences for all of SpaceX’s customers, particularly delaying critical NASA astronaut and US military launches until a lengthy accident investigation is completed. SpaceX executives and managers involved in launch go/no-go decisions clearly understand this and act accordingly.

Starlink-12 will likely be recycled for another launch attempt sometime after ULA’s next Delta IV Heavy launch attempt and probably after SpaceX’s own GPS III SV04 mission for the US military, scheduled no earlier than (NET) 12:02 am EDT (04:02 UTC) and 9:55 pm EDT (01:55 UTC), September 29th, respectively.

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.”
