SpaceX aims for a burst of December launches despite recent delays
Originally scheduled to launch on December 4, SpaceX’s thirteenth resupply mission to the International Space Station (ISS) has been pushed back to no earlier than Friday, December 15 after routine preflight checks identified potential contaminants in the Falcon 9 launch vehicle’s upper stage fuel lines.
The past six weeks have been something of an outlier in an otherwise relentless series of 2017 launches for SpaceX. In early November, defects in payload fairings were discovered at the company’s Hawthorne, CA factory and quickly traced to the Zuma mission’s fairing, at that point already vertical and prepared to launch from Kennedy Space Center. SpaceX chose to pause its launch indefinitely as it investigated the fairings already delivered to its several launch pads and began the process of either repairing or replacing those impacted. The CRS-13 Cargo Dragon mission soon took precedent as Zuma remained on hold.

Although CRS-13 does not require a payload fairing and was thus unaffected by SpaceX’s ongoing investigation, the mission was scheduled to be launched from Launch Complex-40, essentially a new pad after ten months of extensive repairs and upgrades. This translated into a few days of additional delays as the SpaceX launch crew thoroughly tested the pad’s new systems and pushed towards static fire of the flight proven Falcon 9 booster, successfully completed on December 6 after an additional handful of days of pad-related delays. This pushed the launch date from the 4th to the 8th, then the 12th and the 13th to accommodate further limited testing in order to ensure pad readiness. However, routine tests revealed a possible fuel line contamination in Falcon 9’s second stage, and SpaceX delayed the mission an additional 48 hours to resolve the problem. CRS-13 is now aiming for launch no earlier than 7:35am/10:35am PST/EST on December 15, but the window is instantaneous and any additional delays would push the launch into late December, at which point Cape Canaveral Air Force Station returns to operational status with the conclusion of winter holidays.
Although LC-40 suffered through its own teething period of bugs and testing while returning to life, there is a certain irony in the fact that a bug in the only wholly new component of CRS-13’s Falcon 9 rocket has been the most recent cause of delay; both the Falcon 9 booster and Cargo Dragon capsule are refurbished, flight-proven hardware, although both the trunk and heat shield of the Dragon were likely replaced with new components. There is something to be said about the logical nature of truly “flight-proven” hardware being more trustworthy than completely new alternatives, but it is far more likely that the upper stage contamination can be largely traced back to the new pad hardware.

Although Teslarati’s launch photographer Tom Cross has been battered about by Zuma and CRS-13 delays, SpaceX has demonstrated an admirable level of patience and caution, risking significant delays to their launch manifest in order to best ensure the safety and reliability of their launch services. While delays are painful in the spaceflight fan business, they are impermanent and secondary to safety and success. SpaceX will undoubtedly return to their regular programming in no time at all, with the West-coast launch of Iridium-4 and first pad rollout of Falcon Heavy up next on the docket. Stay tuned!

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.”
