Tesla Semi’s temporary ‘Megacharger’ system glimpsed in Madonna Inn sighting
More than a year since unveiling the vehicle, Tesla continues to conduct real-world tests of the Semi across the United States. In its recent sighting, the Semi was spotted while it was charging at the iconic and quirky Madonna Inn, located at San Luis Obispo, CA. This time around, the sighting provided what could very well be the first glimpse at Tesla’s temporary “Megacharger” solution for the Semi test mule.
When Elon Musk unveiled the Tesla Semi, he noted that the vehicle would be supported by a network of “Megachargers,” which are capable of replenishing 400 miles of range in as little as 30 minutes of charging. Unlike the Supercharger Network, which has a power output of roughly 120 kW, speculations are high that Tesla’s Megacharger will see around ten times the power levels. During the vehicle’s unveiling, an image was taken of the long-hauler’s charging port, revealing an 8-pin configuration that’s noticeably larger than the Supercharger ports found on the Model S, X, and 3.
Tesla’s Megacharger Network is yet to be built, though some reservation holders of the long-hauler are already installing dedicated charging stations for the Semi in some of their key facilities. Considering that the Semi test mule is currently conducting real-world tests across the United States, though, Tesla has been utilizing a temporary charging solution for the vehicle using its existing Supercharger Network. That said, the electric car maker has been notably secretive about the Semi prototype’s temporary “Megacharger” system. That is, until recently.

During the vehicle’s recent sighting at Madonna Inn, a part of the Semi’s charger was photographed and shared online by auto enthusiast jerryswhip on Instagram. A member of the r/TeslaMotors subreddit who was present at the Semi’s sighting, u/Jace11, further noted that the long-hauler was connected to a hub that was, in turn, linked to three Supercharger stations. This hub seems to be visible in one of the images taken of the vehicle, as a contraption with a red light could be seen in the area beside the Semi’s charging port.
Following its charging session at the Madonna Inn Supercharger, the Semi headed back into the highway towards San Francisco. Footage taken by Tesla enthusiast Steven M. Conroy showcased the Semi’s impressive speed once more, while capturing the vehicle’s unique, unearthly sound as it accelerated on the freeway. At several points in the video, the now-iconic futuristic whine of the vehicle’s four Model 3-derived electric motors was clearly audible.

Being a vehicle designed to compete in the trucking industry, the Semi has the potential to be the most disruptive offering from Tesla. The vehicle, after all, has several features that make it a viable alternative to diesel-powered semi-trailers, from its four Model 3-derived electric motors, its comparable Class 8 hauling capacity, to its superior speed. In true Tesla fashion, the company continues to develop and improve the Semi, with President of Automotive Jerome Guillen stating that the all-electric truck has been given notable improvements since it was unveiled last year. Some of the Semi’s improvements have been teased by Elon Musk earlier this year as well, with the CEO stating that the long-range variant of the vehicle would have closer to 600 miles of range per charge.
The Tesla Semi has attracted a notable amount of support from several high-profile companies, including PepsiCo, JB Hunt, UPS, and FedEx, to name a few. Even foreign companies such as ASKO in Norway and Bee’ah in the Middle East have also placed orders for the electric long-hauler. Tesla is yet to announce where the Semi would be manufactured, though the company is expected to start producing the vehicle sometime in 2019.

Elon Musk just set a condition that could end Falcon 9 as we know it
Elon Musk says SpaceX will finally retire Falcon 9 once Starship flies reliably every week.
Elon Musk gave the clearest timeline yet for retiring Falcon 9, SpaceX’s workhorse rocket.
The comment came in a reply on X, where Musk wrote that “once Starship is flying reliably several times per week, it makes sense to shift super scarce SpaceX engineering and production resources to Starship to get launch rate to several times per day, which means winding down Falcon.” He was responding to physicist Casey Handmer, who noted that NASA is reportedly uneasy about SpaceX phasing out Falcon after building what Handmer called the most successful launcher ever, with the fleet nearing 1,000 total launches.
Now @SciGuySpace reports NASA is in a tizzy because after running the most successful launcher ever for more than a decade and nearing 1000 launches, @SpaceX is planning to retire Falcon in favor of Starship in a few years.
Sorry, NASA, you’ve had 15 years to burn down the… https://t.co/uCNoMwK0v9

Falcon 9 is still SpaceX’s busiest vehicle by far. The company is on pace for roughly 140 to 145 Falcon flights this year, following 165 in 2025, president Gwynne Shotwell told Time earlier in 2026. She has already said Falcon flights would “tail off” as Starship comes online, while reports indicate that SpaceX has stopped booking new Falcon 9 launches past 2028 and halted production of some expendable Falcon hardware, according to Bloomberg.
It’s worth noting that Musk’s post is a condition, and not a countdown on when Falcon will retire. Starship has not yet flown weekly, let alone daily. Its most recent flight in July ended with a soft splashdown in the Indian Ocean, a milestone Musk pointed to earlier this month when he said the vehicle’s heat shield problem was effectively solved. SpaceX towed that ship to Christmas Island for inspection, and the next flight, Flight 14, is aimed at putting Starship into orbit for the first time. A tower catch attempt for the upper stage has been pushed back to what Musk has called “a few months” away.
SpaceX and a new Trump order that could rewrite the next decade of launches
The gap between Falcon’s role today and Starship’s promised role tomorrow matters most to NASA. Falcon and its Dragon capsule remain the only way the agency rotates astronauts to and from the International Space Station, and Starship is not certified to carry NASA crews. Musk’s post did not address how that handoff would work if Falcon winds down before a crew-rated Starship variant exists. The timing lines up with Musk’s other recent Starship comments. Two days before the Falcon post, he told a different X user that SpaceX is aiming for more than 30 Starship launches a day by 2030, or roughly 10,000 a year, a figure tied to the Trump administration’s new push for higher national launch cadence. Falcon, which took over a decade to reach its first 100 launches, was never built to approach that kind of volume.
For now, Falcon 9 keeps flying at a near-record pace while Starship works to prove it can do the job Musk has already picked out for it.
Tesla Cybercab is set to launch in Austin, Texas, on September 3, as the company has officially started sending out invitations to a dedicated event it will hold in the city where its headquarters is located.
The Cybercab is Tesla’s dedicated ride-sharing vehicle: it features just two seats and has no steering wheel or pedals. It is aimed at fully autonomous passenger transport, and will operate in the Robotaxi fleet alongside the Tesla Model Y, which has been performing driverless rides for real-world passengers for more than a year.
Thank you so much @Tesla for inviting us to the Cybercab launch in Austin! 🤠 pic.twitter.com/F1rAR8zd5O

The launch of the Cybercab marks the next chapter in Tesla’s autonomy story. The company has been developing autonomous transport for years with its Full Self-Driving (Supervised) platform, which is available in any vehicle the company has built with the proper hardware and software capabilities.
Its capabilities vary by hardware and software version, but Tesla says its latest hardware version, known as AI4, can deliver full autonomy. However, future vehicles will operate with even more robust hardware packages, as Tesla will develop AI4.5 and AI5 for even more capability in its vehicles.
Following a report from The Information that surfaced earlier this week, the writing was on the wall that Tesla was set to launch Cybercab in the near term. The report stated Tesla could launch Cybercab as soon as the end of August. Tesla came close and has booked it for September 3.
The big thing with this event being scheduled is not necessarily that Tesla is launching a new vehicle, but instead that it is launching a vehicle that has no steering wheel or pedals and will operate exclusively on a self-driving program that is evidently nearing full autonomy. If the event allows vehicles to take passengers on public roads and drop them off wherever they please within the City of Austin, it will be a drastic advancement in the company’s self-driving story.
People have ridden in Cybercab previously: Tesla had the “We, Robot” event in October 2024, which allowed people to experience fully autonomous rides in a closed circuit at Warner Bros. Studios in Burbank.

Additionally, Tesla launched employee rides in Cybercab in July.
It’s a drastic step forward for Tesla, whose CEO, Elon Musk, has promised for years that the company would release a fully autonomous vehicle and platform capable of allowing drivers to relinquish any responsibility behind the wheel.
Elon Musk put a number on where he thinks SpaceX’s Starship program is headed by 2030, replying on X a day after President Trump signed a memo pushing the country toward 1,000 space launches and reentries a year.
The exchange started when Aaron Burnett, co-founder of propulsion startup Mach 33, posted that “1,000 launches/reentries is the goal,” quoting White House science adviser Michael Kratsios on the newly signed National Space Transportation Policy. Burnett noted that the FAA’s own bull-case forecast reached only 385 annual launches by 2030, while his firm’s conservative model already put SpaceX alone near 940. Musk responded, “We’re aiming to reach 30+ Starship launches/day in 2030, which is ~10k annualized. Still tiny numbers compared to airplane flights!”

That figure is specific to Starship, the rocket SpaceX is still developing for orbital and lunar missions, not the Falcon 9 fleet that carries most of the company’s current launch volume. Starship has flown twice this year, a slower pace than the four and five flights SpaceX managed in 2024 and 2025. Getting from two flights a year to 30 a day is the scale of jump the new federal policy is meant to clear regulatory room for.
Trump’s memo, signed Thursday, directs agencies to identify new launch and reentry sites on federal land, including a new reentry site within 90 days, and to speed up the permitting and environmental reviews that have long slowed cadence growth. It also sets a goal of returning American astronauts to the moon by 2028 and placing initial lunar base elements by 2030, tying the launch buildout directly to NASA’s Artemis program.
SpaceX has already been pushing the FAA toward higher numbers on its own. The agency approved up to 44 annual Starship launches from Kennedy Space Center in February, on top of a 2024 review that raised the cap at Starbase in Texas to 25 a year. Those approvals cover a fraction of the 10,000 annual flights Musk is now describing, which shows how far current permitting still sits from the administration’s stated target.
The near-term test of all this is more modest. SpaceX cleared a full-duration, six-engine static fire on its next Starship vehicle this week, the last major hardware checkpoint before Flight 14, which is targeting no earlier than August 28 and is expected to attempt the vehicle’s first full orbital mission. Musk said last week that a tower catch of the upper stage is still probably months away, a reminder that the immediate roadmap remains far more incremental than the daily launch numbers he just posted.
