SpaceX prepares Falcon 9 booster for eleventh launch and landing [webcast]
SpaceX has confirmed that Falcon 9 is on track to launch another batch of Starlink satellites less than 48 hours after a successful United Launch Alliance Atlas V from a pad just two miles south.
Falcon 9 is now scheduled to launch Starlink 4-9 from Kennedy Space Center (KSC) Launch Complex 39A no earlier than (NET) 9:35 am EST (14:35 UTC) on Thursday, March 3rd. Oddly, unlike Starlink 4-8, which successfully launched 46 Starlink satellites into low Earth orbit (LEO) on February 21st, Starlink 4-9 – following a seemingly identical trajectory – will carry 47 satellites. The reason for the small difference is unclear.
Last month, SpaceX suffered a significant anomaly when a “geomagnetic storm” warmed Earth’s atmosphere, causing 38 of 49 just-launched Starlink 4-7 satellites to prematurely reenter and burn up. In response, while SpaceX hasn’t officially confirmed the change, it appears that all subsequent Starlink missions are being launched to slightly higher parking orbits. In comparison, Starlink 4-4 – a West Coast mission – launched 52 satellites into a 340 x 210 kilometer (210 x 130 mi) parking orbit in December 2021. Starlink 4-7, an East Coast mission, launched 49 satellites into a 336 x 210 km parking orbit on February 3rd, losing three satellites to account for extra performance needed to safely dodge the Bahamas.
Following Starlink 4-7’s space weather calamity, SpaceX – using an identical trajectory – launched 46 Starlink 4-8 satellites (three fewer than 4-7) from the East Coast into a higher 337 x 325 km parking orbit on February 21st. On February 25th, SpaceX also launched 50 Starlink 4-11 satellites (a reduction of two) from the West Coast into a higher 316 x 306 km parking orbit. In short, after Starlink 4-7, SpaceX appears to be sacrificing a few Starlink satellites to launch to parking orbits that are slightly higher and thus slightly more stable.
In theory, this should entirely prevent a repeat of the Starlink 4-7 anomaly while only marginally increasing the amount of time it should take dead-on-arrival satellites to reenter. While doing so increases the number of satellites Falcon 9 can launch, the main reason SpaceX launches Starlink satellites to such low orbits is to ensure that any failed satellites reenter a matter of days to a few weeks after launch instead of the years it could take at their operational ~550 km (~340 mi) orbits.
Of course, that doesn’t explain why Starlink 4-9 is projected to launch one more Starlink satellite than Starlink 4-8. It’s possible that SpaceX is refining its new insertion orbit on the fly and that Starlink 4-9 is headed to a slightly lower destination after data gathered from 4-8 and 4-11. It’s also possible that SpaceX is tweaking some other aspect of Falcon 9’s mission profile or even modifying Starlink satellites (i.e. adding or subtracting mass) – neither of which would be out of the ordinary for the company.
Regardless, Starlink 4-9 is interesting for a few more reasons. First, it will mark drone ship Just Read The Instruction’s (JRTI) first recovery mission since a mistake made by its onboard Octagrabber rocket nearly lead to the loss of an entire Falcon 9 booster in December 2021. That implies that SpaceX has fully determined and rectified the cause of that anomaly and repaired both the drone ship and its robot. To reach its full launch cadence potential, SpaceX needs at least two operational drone ships on the East Coast. Otherwise, in lieu of rare low-performance missions that allow Falcon 9 boosters to fly back to land, SpaceX can only launch one East Coast Falcon 9 mission every 10 or so days and can’t support Falcon Heavy launches that require two at-sea booster landings.
Additionally, SpaceX has confirmed that Falcon 9 B1060 will launch Starlink 4-9. The mission will be its 11th launch and landing attempt, hopefully making it the third Falcon 9 booster to successfully support 11 orbital-class launches after B1051 and B1058. Together, that means that 3 (15%) of the 19 Falcon 9 Block 5 boosters SpaceX has debuted will have singlehandedly supported 33 (37%) of the 89 Falcon 9 launches the company has completed since May 2018. It’s difficult to imagine a more resounding affirmation of SpaceX’s work on reusability.
Tune in to SpaceX Starlink 4-9 webcast around 9:20 am EST (14:20 UTC) on Thursday, March 3rd to watch the launch live.

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.”
