SpaceX’s first government Falcon Heavy launch aiming for “early 2019” per USAF
Linked to the rocket and mission through its own LightSail 2 solar sail satellite, The Planetary Society reports that the USAF and SpaceX are now targeting Falcon Heavy’s first launch for a government customer in “early 2019”.
Previously expected to launch around November 30th, just a month from today, it’s clear that SpaceX’s second Falcon Heavy rocket has yet to approach flight readiness, likely marginalized by a more pressing focus on near-term Falcon 9 missions and Crew Dragon’s imminent flight debuts.

According to Planetary Society, a USAF official provided an update – per the group’s involvement in its STP-2 rideshare launch – stating that its “initial launch capability” was being reassessed, essentially a roundabout way of saying “A new launch date is being determined”. Reasons for the multitude of delays since Falcon Heavy’s successful February 2018 debut are few and far between, with the most likely explanation being some combination of issues with one or several of the ~25 satellites manifested and SpaceX’s ability to build a new Falcon Heavy rocket in time.
However, it’s decidedly ambiguous as to which one of those explanations truly takes precedence, given that SpaceX apparently told the USAF and its customers that it was ready to launch the mission between June and August.
“Officials working on the mission said SpaceX has provided the Air Force and other customers a 60-day window for launch opening on June 13. The Air Force spokesperson confirmed it will be the second Falcon Heavy mission.” – Stephen Clark, SpaceflightNow
Assuming SpaceX’s launch readiness announcement was accurate, the USAF and its customers must have run into some extreme issues while organizing all STP-2 payloads and integrating those satellites onto a custom-built adapter, a task that companies like Spaceflight Industries have shown to often be the long pole of rideshare launches. It’s also possible that SpaceX executives and managers underestimated or undersold the challenge of moving from a Falcon Heavy built solely on old Falcon 9 Block 2 and 3 boosters to an all-Block 5 version of the rocket, featuring a large number of highly-consequential changes like uprated engines and an entirely new approach to assembling each booster’s octaweb.

-
- SpaceX’s second Falcon Heavy launch will either be the USAF’s STP-2, a collection of smaller satellites, or Arabsat 6A, a large communications satellite. (USAF)
Lastly, depending on the nature of the launch contract between them, it’s possible that SpaceX had been planning on reflying Falcon 9 Block 5 boosters as its next Falcon Heavy’s side boosters, a move that would dramatically shorten the lead time required for a new Falcon Heavy to be produced. If the USAF expects or has unconditionally demanded all-new hardware for the launch of STP-2, SpaceX would need at least two (if not three) times the production resources to build and test Falcon Heavy #2, all while paralyzing those resources until well after the rocket’s first flight.
Building three separate Falcon 9/Heavy boosters, acceptance-testing them in Texas, and delivering them to Florida – all under uniquely strict USAF standards – would likely take SpaceX a bare minimum of four months from start to finish. In the guaranteed event that SpaceX had to simultaneously continue regular production, test operations, and preparations for Crew Dragon launches, an all-new Falcon Heavy would likely take more than 6-8 months to make flight-ready while still allowing SpaceX to avoid severe launch delays for its many other customers.

To add additional confusion to the mix, multiple reliable sources have confirmed that STP-2’s actual launch target is closer to March 2019, quite a stretch for “early 2019”. At the same time, Falcon Heavy customer Arabsat has reported that its Arabsat 6A satellite is expected to launch as early as January 2019. Ultimately, clarity can only come from the USAF, Arabsat, or SpaceX itself – for now, we wait.

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.”
