SpaceX’s second Falcon 9 Block 5 booster reuse closes in as rocket refurb continues
Scheduled on October 7th, SpaceX is roughly three weeks out from the next routine launch of Falcon 9, set to carry the ~2800 kg (6200 lb) Argentinian satellite SAOCOM-1A into a low polar orbit from the company’s Vandenberg Air Force Base launch facilities.
Cocooned inside Falcon 9’s payload fairing during the final days of August, the Earth observation satellite’s launch will mark a number of exciting milestones for SpaceX, including the second reuse of a Block 5 booster and the debut of a California-based rocket landing zone barely 400m (1400ft) from the launch pad.

Previously tasked with launching Iridium’s 7th group of 10 NEXT satellites on July 25th, Falcon 9 B1048 has been assigned as SAOCOM 1A’s ride to orbit, originally expected to refly as early as September 5th and September 28th. Despite the delays, it still appears that B1048 will easily snag the SpaceX record for second fastest booster turnaround – 74 days compared to Block 5 booster B1045’s 71 days gap between launching NASA’s TESS and CRS-15 missions.
According to a number of comments from satellite engineers involved in the launch, most of the month-long slip rested on rocket availability, meaning that SpaceX was having some sort of difficulty with Falcon 9 components. Given photos and official comments showing that SAOCOM-1A was encapsulated in its payload fairing more than 5 weeks before launch (August 30th) and that Falcon 9 Block 5 is a fairly new launch vehicle, especially in a flight-proven configuration, the most logical explanation is that SpaceX is simply being extra cautious and thorough with B1048’s post-flight analysis and refurbishment.
It’s entirely possible that SpaceX engineers and technicians could have managed a ~40-day turnaround to make the original September 5 launch date, but it’s equally likely that some off-nominal characteristics were noted while the booster was being prepped for transport after craning off of drone ship Just Read The Instructions. In fact, B1048’s recovery operations were exceptionally lengthy and in-depth, including an extraordinary few hours during which technicians removed the booster’s Merlin 1D access panels, baring wholly-uncovered rocket engines in full view of a public area. Nothing equivalent has ever been observed over the course of more than a dozen Falcon booster recoveries, perhaps indicating some unique circumstances in the case of B1048.

The most obvious explanation is that those publicly-visible inspections were used to judge whether the flight-proven booster could return directly to SpaceX’s Vandenberg launch pad or needed to make a stop at the company’s dedicated Hawthorne factory and refurbishment facilities. Judging from the month-long slip that transpired, it’s probable that the latter option was selected. Regardless, caution is key when a customer’s payload is on the line.
Once it makes its way to the launch pad for the second time, B1048 will have the opportunity to both become the first Block 5 booster to land on land and the first rocket ever to land at SpaceX’s West Coast Landing Zone (LZ), under construction/development for the last two or so years. Just like its Floridan twins, the California LZ will only be an option for particularly lightweight payloads and lower-energy launch profiles, of which SAOCOM 1A (and 1B) certainly fit the bill.

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.”
