SpaceX Falcon Heavy spied on the move ahead of test fire
While touring Florida’s Kennedy Space Center by bus earlier this morning (January 8), several spaceflight fans captured SpaceX’s Falcon Heavy rolling out to Pad 39A for the second time ever. Following a basic fit check and photo opportunity at the launch pad in the last week of 2017, the launch vehicle now appears to be prepped and ready for its first wet dress rehearsal (WDR) and static fire test.
If all goes well during the wet dress rehearsal’s propellant loading tests, an admittedly less than guaranteed outcome, then the WDR will likely translate into a momentous occasion for the massive rocket: the first-ever simultaneous ignition of all three of its integrated first stages and their 27 Merlin 1D engines. While relatively unique to SpaceX, the company has made a habit of testing each and every new Falcon 9 first stage with two full-up static fire ignitions, one at McGregor, Texas and the other at the vehicle’s given launch pad. Following the destructive failure of Falcon 9 during a September 2016 static fire test, SpaceX further upped their cautious procedures by removing the payload for all future static fires, lest the customer request that it remain integrated for the sake of time savings.
Unsurprisingly, no customers have since chosen to bypass SpaceX’s new risk-reducing procedures. Falcon Heavy will clearly be a return to older methods, delineated by the clear presence of the second stage and Tesla Roadster payload at its top, although this decision was almost undoubtedly driven by the fact that the payload is in no real way valuable or even important for the “customer,” SpaceX itself. The Tesla Roadster is more or less a stand-in for the traditional boilerplate satellite (read: hunk of dead metal) often launched during the inaugural flights of new rockets. The best recent example is the 2004 inaugural launch of Boeing’s Delta IV Heavy rocket, similar to Falcon Heavy in the sense that it also features a triple-core first stage. Its first launch carried a payload that was quite literally a 6000 kg (13500 lb) piece of metal paired with a number of sensors used to gather vibrational data.

Somewhat fittingly, Delta IV Heavy is aiming to conduct its own launch within the next week or so, providing the East Coast with back to back launches of the world’s two largest operational rockets. Still, as SpaceX and Elon Musk have repeatedly mentioned, Falcon Heavy is far more capable than even Delta IV Heavy: while Falcon Heavy is noticeably shorter, narrower, and thinner than Delta, it weighs almost twice as much and will sport nearly 2.5 times the thrust at liftoff.
Delta IV Heavy’s launches are undoubtedly spectacles to behold, particularly given explosive launch procedures, but the vehicle is entirely expendable, whereas Falcon Heavy will attempt recovery of all three of its first stages, and may eventually allow SpaceX to test technology that will enable second stage recovery, as well.
Falcon Heavy will launch a somewhat livelier version of Delta IV Heavy’s boilerplate mass-simulator with the Tesla Roadster, and the main goal is quite clearly to test the vehicle’s ability to send a payload into a trans-Martian injection (TMI) orbit, albeit likely without an actual injection into orbit around Mars at the other end. Even if the payload is somewhat silly, a successful launch to TMI would be the most literal step yet made by the commercial space company along its path to Mars. If this week’s propellant loading and static fire go as planned, launch will likely follow within a week or so – maybe two weeks given the new and unpredictable nature of testing what is more or less a prototype rocket.

Falcon Heavy can be expected to go vertical at the pad within the next 12-24 hours at most, and static fire will follow soon after. After a highly successful evening photographing the January 7 launch of Falcon 9 with Zuma, Teslarati’s launch photographer Tom Cross will be attempting to photograph the momentous test fire as it happens, and you can follow along live on Teslarati’s Instagram.

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.”
