SpaceX has released uncut footage of one of its most recent Falcon 9 launches and landings, including unprecedented onboard audio from the rocket through all phases of flight.

The rocket in question, Falcon 9 booster B1059, ended months of delays when it lifted off at long last on August 30th, sending a new upper stage, payload fairing, and an Argentinian Earth observation satellite on their way to orbit. Known as SAOCOM 1B, the second of a pair of synthetic aperture radar satellites launch by SpaceX deployed from Falcon 9 less than 15 minutes after liftoff, followed by two rideshare payloads roughly 45 minutes later.

Booster B1059 separated from the rest of Falcon 9 a little over two minutes after launch and quickly flipped around to perform a boostback burn – quite literally slowing down to zero from Mach 5 and then boosting several dozen miles back towards the Florida coast. The rocket ended its fourth launch with a gentle landing at Landing Zone-1, effectively completing a ~200 km (~120 mi) aerial journey in less than eight minutes with an average velocity substantially faster than the speed of sound.

In the booster camera video SpaceX unexpectedly released after mission completion, one thing stands out above all else: an uninterrupted audio recording of the rocket from liftoff to landing. In the past, SpaceX has occasionally released the odd video from a Falcon 9 booster’s onboard camera, the most recent instance of which was published in 2016. In one other memorable case, SpaceX’s April 2018 launch of NASA’s TESS exoplanet observatory was blessed with uncut booster camera footage during the live webcast. SpaceX never technically released that footage on its own but it was easy enough to cut it from the webcast to offer a clean, uninterrupted view of a Falcon 9 booster launch and landing.

Regardless, in all prior instances and webcasts with booster camera footage, SpaceX has never included audio. It’s generally understood that most modern launch vehicles – including Falcon 9 – are outfitted with numerous high-fidelity microphones. Unintuitively, multiple separate, time-synchronized audio recordings can be used to quite literally triangulate the source of rocket hardware issues in the event of a failure – a technique SpaceX has used to its benefit to investigate Falcon 9’s first in-flight failure in 2015.

In this case, the audio serves no technical purpose but does offer the best birds-ear perspective of a Falcon 9 launch yet published. Roughly sped up by a factor of four, SpaceX’s SAOCOM 1B audio captures the passenger jet-esque whine of Falcon 9’s Merlin 1D turbopumps, the brief silence of engine cutoff, the whistle and vibration of atmospheric reentry, the thump of cold-gas thrusters maintaining the rocket’s attitude in vacuum, and even the clunk of landing leg deployment, among many other notable sounds.

Thanks to a relatively gentle and low-energy landing as a result of the low Earth orbit required by SAOCOM 1B, Falcon 9 B1059 will likely be turned around for a fifth launch and landing in the very near future. The booster may even have a shot at breaking SpaceX’s rocket turnaround record – currently held by Falcon 9 B1058 with two launches just 51 days apart.

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.”
