A local resident spotted a SpaceX Falcon 9 booster heading west out of Florida, likely bound for the company’s SLC-4E Vandenberg Air Force Base (VAFB) launch pad and second California launch of 2019.

Barring a surprise reassignment, the booster Joshuah Murrah caught is Falcon 9 B1051, on its way west some 50 days after successfully supporting Crew Dragon’s March 2nd launch debut. Despite the availability of B1046, B1047, and B1049, B1051 was assigned to the Canadian Space Agency’s (CSA) Radarsat Constellation Mission (RCM) shortly after landing aboard OCISLY, triggering major launch delays. The most logical explanation for customer CSA’s and satellite contractor Maxar Technologies’ curious decision is that they must believe that Falcon 9 Block 5 boosters with more than one launch in their past add more risk than those that do not.

According to an April 16th update from CSA, RCM’s launch was scheduled for no earlier than (NET) late May or early June, although word on the ground is that mid-to-late June is now a more likely target. Contrary to rumors of delays, B1051’s shipment west indicates that SpaceX has more or less completed the booster’s refurbishment, likely the easiest Falcon 9 Block 5 refurbishment yet thanks to its relatively slow and cool reentry after launching Crew Dragon.

B1051 returned to Pad 39A’s integration hangar around March 7th, where it spent approximately 50 days being inspected, refurbished, and prepared for cross-country transport. The booster departed Florida on April 26th and will likely arrive at VAFB around May 2nd. Even assuming a slow trip west and buggy preflight preparations, Falcon 9 should theoretically be ready to launch RCM no later than the third or fourth week of May, barring issues or production delays with the mission’s fairing or Falcon upper stage.

Given that Maxar/CSA chose B1051 at a cost of months of launch delays, they may have needs that far outstretch the normal demands of SpaceX’s private (non-government) customers, not out of the question given that CSA is a national space agency and RCM is a high-value (~$1B) science mission. Short of flying on a new Falcon 9 booster, B1051 does theoretically seem to offer the least risk of failure insofar as one can claim that boosters that have completed more launches are more likely to fail.

SpaceX would likely vehemently deny such a claim given their position that highly reusable rockets – much like aircraft – will actually become more reliable and trustworthy the more they launch. Both positions make sense in theory but theory falls flat in the face of actual data, of which only SpaceX and certain customers have access to.

As an external observer, the best data available is a binary public record of Falcon 9 launch success, as well as the degree to which missions are delayed beyond their scheduled launch targets. Falcon 9 Block 5 boosters have launched 16 times in 11 months, six of which used a flight-proven first stage. Flight-proven boosters appear to be a bit more finicky than unflown rockets in terms of late-stage launch delays, but the data is inconsistent and the sample size statistically insignificant. More generally, Falcon 9 and Falcon Heavy have launched 72 times in nine years and suffered two total failures, both caused by unflown upper stages. In 72 launches, including 20 missions with flight-proven boosters, a Falcon 9/Heavy first stage has never caused a total mission failure.

In short, it’s impossible to intuit any clear performance or reliability advantage without the sort of granular per-mission data that only SpaceX and privileged customers have access to. In general, Falcon 9 – reused or not – has consecutively completed 41 successful launches since its second and last mission failure in September 2016, half (49%) of which used flight-proven boosters. Of course, customers have every right to their own standards and expectations of quality and risk-reduction, but Falcon 9’s performance largely speaks for itself at this point – anything beyond its default record of mission assurance is just icing on the proverbial spaceflight cake.

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’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 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.”
