SpaceX has successfully completed a static fire of its newest Falcon Heavy center core, a sign that the most challenging hardware is firmly on track for a late-June launch target.

Currently penciled in for June 22nd, Falcon Heavy’s third launch is of great interest to both SpaceX and its customer, the US Air Force. Most of the two-dozen payloads manifested on the mission are admittedly unaffiliated with the US military. However, the rideshare – known as Space Test Program 2 (STP-2) – was acquired by the USAF for the branch to closely evaluate and certify SpaceX’s Falcon Heavy rocket for critical military launches. The potential upsides of a successful demonstration and evaluation are numerous for both entities and would likely trigger additional positive offshoots.

The Center Core experience

Beyond the general contractual aspects of STP-2, the mission is significant because it will use the third Falcon Heavy center core and second Block 5 variant to be built and launched by SpaceX. Of the technical issues that complicated and delayed SpaceX’s Falcon Heavy development, most can probably be traced back to the rocket’s center core, practically a clean-slate redesign relative to a ‘normal’ Falcon 9 booster.

Most of that work centered around the extreme mechanical loads the center core would have to survive when pulling or being pulled by Falcon Heavy’s two side boosters. Not only would the center core have to survive at least two times as much stress as a Falcon 9 booster, but that stress would be exerted in ways that Falcon 9 boosters simply weren’t meant to experience, let alone survive. After years of work, SpaceX arrived at a design that dumped almost all of that added complexity squarely on the center core and the center core alone. The side boosters would need to use nosecones instead of interstages and have custom attachment points installed on their octawebs and noses, but they would otherwise be unmodified Falcon 9 boosters.

On top of that, SpaceX’s Falcon upper stage and payload fairing would require no major modifications to support Falcon Heavy missions. On the opposite hand, the center core would require extensive rework to safely survive the trials of launch, let alone do so in a fashion compatible with booster recovery and reuse. Per the landing photos above, it’s difficult to tell a Falcon Heavy center core apart from a normal Falcon 9 booster, but the small visible changes are just the tips of several icebergs. Aside from a slight indication that the center core’s aluminum alloy tank walls are significantly thicker (they are), center cores feature a variety of unique mechanisms on their octawebs and interstages. All are involved in the tasks of locking all three boosters together, transferring side booster thrust to the center core, and mechanically separating the side boosters from the center core a few minutes after launch.

Underneath those mechanistic protuberances are the structural optimizations needed for a center core to survive the ordeal of launch. In short, to solve for those new loads, SpaceX wound up building a new rocket. Designing and building a new rocket – especially one as complex as Falcon Heavy’s center core – is immensely challenging, expensive, and time-consuming, particularly for the first few built. Like most complex products, building the first two Falcon Heavy center cores was probably no different. To make things worse, boosters 1 and 2 were based on totally different versions of Falcon 9 (Block 3 vs. Block 5), requiring even more work to further redesign and requalify the modified rocket.

This is where the center core assigned to Falcon Heavy Flight 3 and pictured above comes into play. Built just a few months apart from B1055, the first finished Falcon Heavy Block 5 center core, the newest center core – likely B1057 – is also the first to be built with the same design and manufacturing processes used on its predecessor. In other words, SpaceX can at long last begin serial production of Falcon Heavy center cores, allowing its engineering, production, test, and launch staff to finally get far more accustomed to the unique hardware.

Given Falcon Heavy’s healthy and growing manifest of 5-6 launches, SpaceX will probably need to build several additional Block 5 center cores over the next several years, hopefully resulting in a more refined flow for production, testing, and refurbishment. B1057 will be an excellent candidate for the first reused Falcon Heavy center core thanks to STP-2’s lightweight nature and an extremely gentle landing trajectory. With respect to Flight 3’s schedule, Crew Dragon’s April 20th explosion means that Falcon Heavy will have Pad 39A all to itself for many months to come. Truly the epitome of bittersweet, no doubt, but it does improve the odds that Falcon Heavy’s June 22nd STP-2 launch target will hold.

South Korea’s electric vehicle market saw a notable rise in 2025, with registrations rising more than 50% and EV penetration surpassing 10% for the first time. 

Data from the Korea Automobile and Mobility Industry Association showed that the Tesla Model Y, which is imported from Gigafactory Shanghai, emerged as one of the segment’s single biggest growth drivers, as noted in a report from IT Home News.

As per the Korea Automobile and Mobility Industry Association’s (KAMA) 2025 Korea Domestic Electric Vehicle Market Settlement report, South Korea registered 220,177 new electric vehicles in 2025, a 50.1% year-over-year increase. EV penetration also reached 13.1% in the country, entering double digits for the first time. 

The Tesla Model Y played a central role in the market’s growth. The Model Y alone sold 50,397 units during the year, capturing 26.6% of South Korea’s pure electric passenger vehicle market. Sales of the Giga Shanghai-built Model Y increased 169.2% compared with 2024, driven largely by strong demand for the all-electric crossover’s revamped version.

Manufacturer performance reflected a tightly contested market. Kia led with 60,609 EV sales, followed closely by Tesla at 59,893 units and Hyundai at 55,461 units. Together, the three brands accounted for nearly 80% of the country’s total EV sales, forming what KAMA described as a three-way competitive market.

Imported EVs gained ground in South Korea in 2025, reaching a market share of 42.8%, while the share of domestically produced EVs declined from 75% in 2022 to 57.2% last year. Sales of China-made EVs more than doubled year over year to 74,728 units, supported in no small part by Tesla and its Model Y.

Elon Musk, for his part, has praised South Korean customers and their embrace of the electric vehicler maker. In a reply on X to a user who noted that South Koreans are fond of FSD, Musk stated that, “Koreans are often a step ahead in appreciating new technology.”

Samsung Electronics seems to be ramping its efforts to start operations at its Taylor, Texas semiconductor plant, which will produce Tesla’s next-generation AI5 chip. 

Preparing for Tesla’s AI5/AI6 chips

As per a report by Sina Finance, Samsung Electronics is looking to begin trial operations of extreme ultraviolet (EUV) lithography equipment at its Taylor facility in March. These efforts are reportedly intended to support the full production of Tesla’s AI5 chips starting in the latter half of 2026.

The Taylor factory, Samsung’s first wafer fabrication plant in the United States, covers roughly 4.85 million square meters and is nearing completion. Media reports, citing contractors, have estimated that about 7,000 workers now work on the factory, about 1,000 of whom are reportedly working from the facility’s office building. 

Samsung is reportedly preparing to apply for a temporary occupancy permit, which would allow production to begin before the plant is fully completed.

Tesla’s aggressive AI chip roadmap

Elon Musk recently stated that Tesla’s next-generation AI5 chip is nearly complete, while early development on its successor, AI6, is already underway. Musk shared the update in a post on X, which also happened to be a recruiting message for engineers.

As per Musk, Tesla is looking to iterate its in-house AI chips on an accelerated timeline, with future generations, including AI7, AI8, and AI9, targeting a roughly nine-month design cycle. He also stated that the rapid cadence could allow Tesla’s chips to become the highest-volume AI processors in the world.

Previous reports have indicated that Samsung Electronics would be manufacturing Tesla’s AI5 chip, alongside its rival, Taiwan Semiconductor Manufacturing Company (TSMC). The two suppliers are expected to produce different versions of Tesla’s AI5 chip, with TSMC using a 3nm process and Samsung targeting 2nm production.

Elon Musk’s tunneling startup, The Boring Company, has been studying a potential tunnel system connecting Reno to Tesla Gigafactory Nevada, as per documents obtained by Fortune. The early-stage feasibility work was funded by a state-affiliated economic group as officials searched for alternatives to worsening traffic and accidents along Interstate 80.

Potential Giga Nevada tunnel

Documents reviewed by Fortune showed that The Boring Company received $50,000 in October to produce conceptual designs and a feasibility report for a tunnel beneath a nine-mile stretch of highway leading to Gigafactory Nevada. The payment came from the Economic Development Authority of Western Nevada (EDAWN), a nonprofit that works with the state to attract and expand businesses.

The proposed tunnel was one of several transportation alternatives being explored to address rising congestion and accidents along Interstate 80, which serves the Tahoe-Reno Industrial Center. The massive industrial park houses major employers, including Tesla and Panasonic, both of which had been in contact with the Nevada Governor’s Office regarding potential transportation solutions.

Emails obtained through public records requests showed that Tesla and Panasonic have also supported a separate commuter rail study that would use existing freight rail alongside the Interstate. It remains unclear if The Boring Company’s feasibility report had been completed, and key details for the potential project, including tunnel length, cost, and if autonomous Teslas would be used, were not disclosed.

Relieving I-80 congestion

Traffic and accidents along I-80 have increased sharply as data centers and new businesses moved into the 107,000-acre industrial center. State transportation data showed that the number of vehicles traveling certain stretches of the highway during peak hours doubled between January and July 2025 alone. Roughly 22,000 employees commute daily to the industrial park, with nearly 8,000 working for Tesla and more than 4,000 for Panasonic at the Giga Nevada complex.

Bill Thomas, who runs the Regional Transportation Commission of Washoe County, shared his thoughts about safety concerns in the area. “At this point in time, there’s about (one accident) every other day,” he said. He also noted that he is supportive of any projects that could alleviate traffic and accidents on the Interstate.

“We’re not paying for it. I’m not involved in it. But I understand there are conversations exploring whether that could be done. If there’s a private solution that helps the problem and improves safety, as far as I’m concerned, more power to them,” Thomas stated.
