Years before the space agency’s flagship Europa Clipper mission is scheduled to lift off, NASA and SpaceX are already determining the specifics of the launch – including which Falcon Heavy boosters will support it.
On July 23rd, 2021, after years of rumors, NASA officially announced that it no longer planned to launch Europa Clipper on its own SLS rocket and would instead contract with SpaceX to send the spacecraft to Jupiter on a Falcon Heavy. In terms of sheer prestige, no other mission on Falcon Heavy’s manifest comes close. Expected to weigh around six tons (~13,000 lb), Europa Clipper is a building-sized spacecraft that aims to orbit Jupiter for years, performing dozens of flybys of the planet’s icy moons – several of which almost certainly have liquid oceans.
Europa – the mission’s namesake – is its primary focus and whether or not the funding or political motivation for such an ambitious mission transpires, Europa Clipper was always partially meant to be a scouting mission for a nuclear-powered lander. On its own, though, Clipper has already blown past its original $2B budget target from 2013 and is now on track to cost more than $4.5B, making it the most expensive NASA mission currently in development – second only to the ~$9B James Webb Space Telescope (JWST). In other words, NASA is entrusting SpaceX to launch what is perhaps the most expensive mission to the outer solar system in the history of planetary exploration.
That makes it all the more noteworthy that NASA has already given the okay for SpaceX to plan to launch Europa Clipper on a Falcon Heavy rocket with at least two of its three boosters already flight-proven. According to mission scientist Bob Pappalardo, Clipper Mission Design Lead Brett Buffington revealed in spacecraft “System Integration Review” that SpaceX intends to reuse two Falcon Heavy side boosters that are currently scheduled to debut as early as next year on a different NASA mission. Known as Psyche, that mission – also scheduled to fly on Falcon Heavy – is scheduled to launch no earlier than (NET) August 2022 and is designed to explore an asteroid that’s believed to be almost entirely composed of metal.
With Europa Clipper scheduled to launch NET October 2024, that undoubtedly makes this the earliest a Falcon booster assignment has ever been confirmed – and probably the earliest SpaceX itself has assigned flight-proven boosters to a specific mission. It also makes those particular boosters quite special. Unlike Psyche, which will leave plenty of margin for SpaceX to recover at least two of Falcon Heavy’s three boosters, Europa Clipper will need almost every ounce of performance the rocket can give to send the much larger spacecraft much faster and further. Barring a major surprise, that means that Falcon Heavy will launch Europa Clipper in a fully expendable configuration.
For SpaceX, being able to use at least two flight-proven proven boosters on that expendable mission will make expending two Falcon Heavy boosters – which are otherwise capable of launching at least ten times in their lifetimes – a much easier pill to swallow. For NASA, the space agency is likely already familiar with the reality that flight-proven hardware actually improves schedule confidence, which is crucial for a mission like Europa Clipper thanks to its 21-day launch window.
Nonetheless, it does still raise the question of whether NASA will allow SpaceX to fly Psyche’s Falcon Heavy side boosters once or even twice more in the more than two years they’ll otherwise have to spend in storage between Psyche and Europa Clipper. A Falcon Heavy rocket is currently scheduled to launch a commercial Moon lander and NASA’s VIPER Moon rover as early as Q4 2023. Most recently, NASA purchased a Falcon Heavy to launch NOAA’s GOES-U weather satellite NET Q2 2024. In 2022 alone, SpaceX also has at least three other non-NASA missions scheduled to launch before Psyche, raising another possibility that Psyche itself might fly on once-flown boosters that would then fly a third, fourth, or even fifth time with Europa Clipper.
That might seem like an unlikely possibility but NASA has already shown that it’s happy to launch Cargo Dragons on boosters with multiple non-NASA missions in their pasts and will soon launch DART – an asteroid impact spacecraft – on another Falcon booster that last launched Starlink satellites. Additionally, with Arabsat 6A and STP-2, SpaceX already demonstrated in 2019 that it can launch Falcon Heavy, recover its two side boosters, and relaunch those same boosters on a different Falcon Heavy mission less than two months later – and for the US military, no less.

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.”
