SpaceX tracks towards first launch of 2019 with flight-proven Falcon 9 static fire
SpaceX has completed a Falcon 9 static fire test ahead of the company’s first launch of 2019, kicking off what is looking to be a truly jam-packed year for Falcon 9 and BFR. Most important, of course, is SpaceX’s primary business and main sources of revenue – safely and reliably launching customer satellites, payloads, and – soon – astronauts into orbit.
Previously tasked with launching heavy communications satellite Telstar 18V in September 2018, Falcon 9 B1049 is now set to launch an arguably historic mission for both SpaceX and customer Iridium, the eighth and final contracted launch of the upgraded Iridium NEXT satellite communications constellation.

Struck all the way back in June 2010, Iridium’s decision to award the full NEXT constellation launch contract to SpaceX less than two weeks after Falcon 9’s first and only launch may well be the greatest calculated leap of faith in the history of commercial spaceflight. SpaceX did admittedly offer an unbeatable price ($492M for eight launches, $61.5M per launch) that may have allowed Iridium to afford a new constellation in the first place, but the risk Iridium took was truly immense at the time.
Originally launched between 1997 and 1998, the first Iridium constellation became and still remains the only satellite communications constellation in history to offer global and persistent coverage anywhere on Earth, allowing those with Iridium devices to guarantee connectivity no matter where they are. To some extent, the original constellation has become a subtle but omnipresent backbone of a huge variety of ventures, companies, and services, ranging from marine vessel tracking and emergency response to the go-to solution for those heading far off the beaten path. As just one small example, SpaceX’s large fleet of sea-going vessels and its cross-country transport infrastructure both rely on Iridium for streamlined company-wide movement tracking, making life considerably easier for logistics and planning teams.

Iridium’s decision to use SpaceX for its NEXT constellation likely also gave SpaceX a massive stature boost, taking it from the company with just a handful of commercial contracts that had failed three of its last five launches to the company that secured what was at the time the largest single commercial launch contract in history. Alongside NASA’s Commercial Orbital Transport Services (COTS) and Resupply Services (CRS) commitments (~14 launches as of 2010), Iridium NEXT raised SpaceX’s commercial manifest from perhaps 2 missions to ~10 while also taking the value of those contracts from an almost negligible sum to well over half a billion dollars.
Although SpaceX and Iridium originally planned for launches to take place over a roughly 24-month period stretch from 2015 to 2017, unplanned technical delays and a duo of catastrophic Falcon 9 failures (CRS-7 and Amos-6) in 2015 and 2016 ultimately pushed Iridium NEXT’s launch debut back several years. Despite those immense hurdles and a range of smaller issues, SpaceX and Iridium were finally able to begin launching satellites in January 2017 and have continued to consistently do so every 3-4 months since then. Aside from one partial NASA rideshare mission that featured five NEXT satellites in May 2018, all seven launches have placed ten NEXT satellites (weighing approx. 10,000 kg or 22,000 lb total) in a variety of low polar orbits without a single known hitch.

Falcon 9 enters the era of reusability
Closely following SES, NASA, and SSL (BulgariaSat), Iridium also became the fourth commercial entity to launch on a flight-proven Falcon 9 rocket for the launch vehicle’s fourth flight-proven mission ever. Iridium-8 will become the fourth constellation launch to fly aboard a sooty Falcon 9 rocket, meaning that a full 50% of the next-gen satellites will have launched on reused rockets, easily one of the coolest bragging rights ever. Currently standing at 65 NEXT satellites in orbit and rapidly nearing operational status, Falcon 9 B1049 and a fresh upper stage will (fingers crossed) place the last ten satellites in orbit to complete the constellation’s last plane and seal the last gap in its perfect global coverage.
Although NEXT would have been valuable for the sole reason that its predecessor satellites are now 5-10 years past their designed lifespans, NEXT will also serve to dramatically increase Iridium’s overall bandwidth, slash concurrent user bottlenecks, and provide a platform for new services like Aireon, which hopes to become the first operator of a truly commercial aircraft tracking service with global satellite-based coverage.

All things considered, it will be hugely bittersweet to watch Iridium and SpaceX’s direct relationship come to a close with the launch of Iridium-8. Aside from nine additional on-orbit spares once all 75 are launched, Iridium will also have a complement of six more spares that will be kept in storage on the ground until they are required in orbit. If or when those times come, SpaceX will be able to compete with other launch providers for the opportunity to carry maybe one or two Iridium satellites – likely as rideshare payloads – into orbit sometime in the future.

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.”
