SpaceX nails second Falcon 9 landing in 48 hours, fairing catch foiled by weather
Just a handful of days after SpaceX’s second-ever successful launch and landing of their upgraded Falcon 9 Block 5, the company has completed the same feat on the opposite side of the United States, debuting the Block 5 rocket with a launch and booster recovery from California’s Vandenberg Air Force Base (VAFB).
The booster in question, Falcon 9 B1048, is the third Block 5 booster to roll off of SpaceX’s Hawthorne, CA assembly line and is now the first Block 5 rocket to launch from the company’s California launch facilities. On the opposite coast, SpaceX’s second Block 5 Falcon 9 booster (B1047) completed its own successful launch and landing, lofting the heaviest commercial satellite to ever reach orbit (Telstar 19V).
While weather during camera setup was absolutely spectacular, the predawn launch window meant that no sun was available to force the ever-present VAFB fog back over the ocean. (Pauline Acalin)
Seven months, fourteen launches
Today’s near-flawless predawn mission saw Falcon 9 place 10 Iridium NEXT satellites in a polar Earth orbit, during which the rocket’s Block 5 booster completed the first landing on Just Read The Instructions in nearly ten months and Mr Steven made his first attempt at catching a parasailing Falcon fairing with his massive net and arms upgrades. Those upgrades, tracked tirelessly by Teslarati photographer Pauline Acalin for the better part of July, took barely a month to go from a clean slate (old arms and net fully uninstalled) to operational, fairing-catching status, an ode to the incredible pace at which SpaceX moves.
Sadly, the vessel’s Iridium-7 fairing catch attempt was sullied from the start by inclement weather – primarily wind shear – that significantly hampered the accuracy of each fairing halve’s parafoil guidance, meaning that Mr Steven’s crew did see the parasailing halves touch down, but too far away to catch them in Mr Steven’s large net. Falcon 9 B1048 had its own difficulties thanks to what engineer and webcast host John Insprucker described as “the worst weather [SpaceX] has ever had” for a Falcon booster landing. Nevertheless, Falcon 9 appeared to stick an off-center but plenty accurate landing aboard drone ship JRTI, although SpaceX technicians are likely going to wish they had the same robotic stage securer located aboard OCISLY on the opposite coast.

Just Read The Instructions, on the other hand, was similarly tracked but primarily to verify that nothing was happening – the vessel’s last operational trip to the Pacific Ocean dates back to the first half of October 2017. Since then, SpaceX began a process of intentionally expending Falcon 9 boosters that had already flown once before, choosing to essentially start from scratch with a fresh fleet of highly reliable and reusable Falcon 9 Block 5 boosters rather than recover older versions of the rocket and attempt to refurbish them beyond the scope of their designed lifespans.
The Block 5 design, however, has taken the countless lessons-learned from flying and reflying previous versions of Falcon 9 and rolled them all into one (relatively) final iteration of the ever-changing rocket. With any luck and at least a little more iteration, Falcon 9 Block 5 boosters should be capable of launching anywhere from 10 to 100 times, 10 times with minimal or no refurbishment and 100 times with more regular maintenance, much like high-performance jet aircraft do today.
Looks good, but so many details need to be right. Journey back from hypersonic becomes extremely difficult as velocity increases. Altitude is easy, velocity is hard.

With three successful launches of new Block 5 boosters now under the new version’s belt, it’s safe to say that the rocket is off to an extremely good start. The most important milestones to watch for over the next several weeks and months will be the first reflight of a recovered Block 5 rocket, the first reuse of a Falcon 9 payload fairing, and then the first third/fourth/fifth/etc. reuse of Block 5 booster. On the horizon, of course, is SpaceX CEO Elon Musk’s challenge to launch a Falcon 9 Block 5 booster two times in less than 24 hours, and do so before the end of 2019.

Roughly 3,000 miles to the East, SpaceX’s just-recovered Florida Block 5 booster wrapped up a picture-perfect arrival in Port Canaveral aboard drone ship Of Course I Still Love You at the exact same time as another Block 5 rocket was launching (and landing) on the opposite coast.

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.”
