SpaceX Starship booster weathers thunderstorm ahead of first ‘cryo proof’
Update: SpaceX’s first Super Heavy cryo proof test is now scheduled no earlier than 6pm to 12am CDT (UTC-5) on Thursday, July 8th 6am to 8pm CDT (UTC-5) on Friday, July 9th. Weather is suboptimal, with intermittent heavy rain – to the extent that a flash flood warning is in effect until Friday evening – expected over the next few days.
Nevertheless, Booster 3 was spotted venting for the first time ever around 9am, suggesting that SpaceX might still try for at least a test or two later today or tomorrow.
Meshing with road and beach closures requested earlier this week, Next Spaceflight reports that a SpaceX Super Heavy booster is scheduled to attempt a ‘cryo proof’ test for the first time as early as Thursday, July 8th.
Known as Booster 3 (B3), SpaceX rolled the first functional Super Heavy prototype – the largest rocket booster ever completed – from the factory to the launch pad on July 1st. One week later, SpaceX appears to be on track to kick off Super Heavy’s first fully-integrated qualification testing, building off of an apparently successful campaign of pressure testing with booster test tank BN2.1. After completing several tests, BN2.1 was rolled back to a scrapyard near SpaceX’s Boca Chica factory, while part of the custom-built stand used for the campaign was then reinstalled on one of the two ‘suborbital mounts’ used for Starship testing over the last year.
Mere days after Mount A’s modifications were completed, Super Heavy Booster 3 was transported to the pad and installed atop it. For whatever reason, SpaceX technicians and engineers spent the next week scouring the rocket’s exterior and interior with the help of an army of boom lifts, turning the basic structure into a functional pressure vessel with all necessary power, telemetry, and plumbing.
99% of that closeout work could have seemingly been done under the cover of SpaceX’s high bay, where Booster 3 was assembled out of dozens of steel rings and domes, but the work appears to have been completed regardless. Workers had to contend with routine South Texas downpours and thunderstorms on Tuesday and Wednesday but were otherwise subjected to fairly mundane winds and weather.
Conditions were most dramatic on Tuesday, with torrential rain only interrupted by the occasional lightning bolt – though Booster 3 and the orbital launch pad’s skyscraper-sized launch tower appeared to make it through the day strike-free.
Now seemingly fully outfitted with all necessary avionics, wiring, and plumbing, Booster 3’s next major objectives will be ambient and cryogenic proof tests, referring to the process of verifying the structural integrity of the rocket first with benign nitrogen gas and later with supercool liquid nitrogen. SpaceX has performed at least a dozen or two ‘cryo proofs’ over the last 18 months and, at this point, qualification testing is fairly routine.
However, Super Heavy B3 is the largest rocket booster ever built and testing such a massive rocket will necessarily force SpaceX to tread some new ground. In fact, it’s not actually clear how exactly SpaceX will perform Booster 3’s first cryo proof given that the suborbital launch complex hosting it has nowhere near enough cryogenic storage capacity to fully fill Super Heavy with more than 3000 tons (~6.6 million lb) of liquid nitrogen.
As always, testing massive, brand-new rockets is no simple feat, so delays are possible – if not outright likely. Regardless, Super Heavy B3’s first test window is scheduled from noon to 8pm CDT (UTC-5) on Thursday, July 8th, with two backups from 6am to 8pm on July 9th and 12pm to 8pm on July 12th. Stay tuned for updates on the first tests of a full-size Super Heavy booster!

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.”
