SpaceX continues to build full-scale Starship hardware at a jaw-dropping pace, testing the limits of rocket production to complete the fifth full-scale prototype in three months and prepare the ship for its first Raptor engine ignition tests.

This time around, SpaceX CEO Elon Musk is fairly confident that the latest Starship prototype – known as serial number 3 (SN3) – has the best chance yet of becoming the first full-scale ship to pass acceptance tests and kick off a Raptor engine static fire campaign. A step further, if said static fires go according to plan, Starship SN3 could become the first full-scale vehicle of its kind to perform controlled flight tests.

Starship SN3 will thus attempt to follow in the footsteps of Starhopper and hopefully avoid an unintentional launch debut similar to the one that destroyed Starship SN1 earlier this month. A successful Starship flight test powered by three Raptor engines would be a major bode of confidence in the upgraded rocket factory SpaceX is building in South Texas. Musk recently made it clear that setting up the machine that builds the machine is currently just as important as individual Starship tests. Thankfully, given that SpaceX is already managing to build colossal rocket prototypes in a matter of weeks for what has to be pennies on the dollar, all with a team of just a few hundred people, the next Starship test campaign is likely just a week or two away.

On March 9th, Musk revealed that the Starship SN2 prototype – an incomplete tank repurposed for specific testing – had passed a proof test with flying colors. SN2’s brief test campaign managed to prove that SpaceX had already fixed the weak point believed to have destroyed Starship SN1 less than two weeks prior. Featuring a redesigned engine section and thrust structure (or “thrust puck,” per Musk), the Starship SN2 test tank survived pressure testing and even made it through engine thrust simulations with the help of an industrial-scale hydraulic jack.

Transformed into a test tank, Starship SN2 successfully passed its proof tests on March 8th, paving the way for SN3+ to aim higher. (NASASpaceflight – bocachicagal)

While the tank passed its tests looking no worse for wear, the last-second design changes SpaceX had to make to rapidly perform thrust structure verification testing made it impossible to repurpose for any alternative use. Starship SN2 has thus been relegated to the scrapyard, a technical necessity but also a sign of both the program’s high rate of progress and low prototype cost. SpaceX’s Boca Chica factory has already more or less completed a new engine section for Starship SN3 and is probably just a day or two away from integrating it with the rest of the steel vehicle.

Less than three days after SpaceX’s brand new vehicle assembly building (VAB) had a single, small Starship section sat inside it, two additional sections of Starship SN3’s tank section departed their fabrication tents and were stacked on March 18th. Less than a day later, the third segment of the rocket’s tank section capped off the two that were stacked the day before. Once those three stacked sections are fully welded together to form a single, cohesive piece of steel, it will need to be stacked atop the aft tank dome and thrust structure to effectively complete Starship SN3’s tank section.

Starship SN3’s thrust structure and aft dome was flipped on March 18th and will likely be ready for installation just a day or two from now. (NASASpaceflight – bocachicagal)

After all four sections are joined, technicians will need to install a few internal parts, but most remaining work mainly involves running wiring and plumbing for power, communications, propellant management, and pressurization. More likely than not, SpaceX replicate its Starship Mk1 and SN1 testing strategy and bring Starship SN3’s tank section to the launch pad for proof testing as soon as outfitting is complete. If the rocket passes proof testing, SpaceX can – for the first time – install functional Raptor engines on a full-scale Starship prototype and begin a crucial wet dress rehearsal (WDR) and static fire test campaign.

At the current rate of progress, SpaceX could easily be ready to transport Starship SN3 to the pad within the next week, give or take. Stay tuned for updates as the company works to quickly finish SN3 integration and move onto the testing phase.

Tesla Cybercab uses a unique strategy for picking up the right rider

Published

Tesla Cybercab is using a unique strategy for picking up the correct rider, which is a crucial part of ride-hailing to ensure people end up in the right place and are charged the correct price.

Cybercab will utilize an RGB strip in its front light bar that will illuminate in a variety of different colors to mark itself.

This identifying mark will also appear in the Robotaxi app, giving riders in the same location a notable distinction in an effort to avoid any confusion regarding who should get in each vehicle.

Other ride-hailing services use similar strategies: Lyft and Uber rides are recognizable through driver identity, vehicle type and color, as well as license plate. Waymo will display the rider’s initials on top of the vehicle, letting them know that the specific vehicle for them has arrived.

Tesla’s strategy is unique and interesting, but there are some flaws. Cybercab’s main purpose is aimed toward being an autonomous ride for all, including those who have disabilities like being blind or even color blind.

Tesla will likely have something in the pipeline for those who cannot see colors or have limited vision. There will definitely be multiple ways to identify which vehicle is the one that “you” specifically ordered.

Cybercab is set to start giving public rides next Thursday, September 3, in Austin, as it announced a dedicated event last week and invited many members of the Tesla community.

Tesla will launch Cybercab on September 3

Additionally, members of the public will be invited as well. Tesla has been offering employee rides in Cybercab for nearly two months.

Tesla ends in-house wrap service that always seemed like a short-term program

Published

Tesla has said goodbye to one customization option for its vehicles: the wrap service it launched several years ago.

After launching an in-house wrap service in August 2020 for the first time in China. In the U.S., it launched in October 2023. Tesla continued to expand the program and adjust it with better pricing and fewer options for the Cybertruck.

By December 2023, it was giving owners of the Model 3, Model Y, and the Cybertruck the opportunity to give their vehicle a fresh look with a vinyl wrap.

It was only available in five locations: Costa Mesa, Oceanside, Santa Clara, West Covina, all in California, and Seattle, Washington.

However, Tesla made some big adjustments to its shop, and the wrap service is officially gone:

Wraps are very popular across the Tesla lineup, especially since the company offers relatively few colors. Many choose to wrap their Teslas with interesting colors, patterns, or even finishes, turning their cars from glossy to satin or matte.

However, Tesla’s wrap service was so limited geographically that it never really had a chance to get off the ground or compete with local shops. Every area in the United States is now overflowing with detailing shops, mobile detailers, and other automotive specialists, many of whom perform wrap services.

Tesla’s service was confined to the Pacific time zone and only spanned across two states. It was never going to be something Tesla was a major competitor in, nor was it going to disrupt the wrapping industry. Now that the program has ended, it seems pretty ideal to believe it was always going to be a short-term thing.

Along with the wrap service, Tesla removed several other products, but nothing too crazy. The Model 3 Door Pocket and Cupholder Liners, the Model S 19″ Magnetite Wheel and Winter Tire Package, Model X/Y Ski/Snowboard Carrier for Hitch Rack, Tesla’s Electric Summer Party Tee, and the Electric Summer Tee were the other items the company totally eliminated from its online shop.

Tesla Robotaxi fleet gets a brain upgrade ahead of Cybercab launch event

Tesla’s Robotaxi service now runs longer hours nationwide as its unsupervised fleet quietly grows larger.

Published

Tesla’s Robotaxi service just got easier to catch, with the company’s official Robotaxi account noting that rides are now available from 6 a.m. to 10 p.m., seven days a week, across its operating footprint. The account also said its unsupervised fleet is “a lot bigger” than before, though without specifics. The bigger change is what Tesla says upgraded intelligence in vehicle distribution and routing is what’s actually cutting wait times, not a new Full Self-Driving version.

While Tesla did not name the team behind the upgrade, the language points to its AI and fleet software group rather than the driving stack itself. Vehicle distribution and routing in Robotaxi has functioned mostly as a dispatch problem with the software deciding which idle car goes to which rider, and how far it has to travel to get there. “Upgraded intelligence” suggests a smarter version of that dispatch logic, likely using demand forecasting to position idle cars near where riders are about to request them rather than reacting once a request comes in. Tesla’s AI division has built similar prediction systems for other parts of the business, including the neural networks that power FSD itself, so applying that same approach to fleet logistics would be a natural extension rather than a new discipline for the team.

Tesla is also about a week away from a separate robotaxi milestone. The company plans to launch Cybercab, its purpose built two seat robotaxi with no steering wheel or pedals, in Austin on September 3. Cybercab has been giving employees rides on public and private roads for weeks, and the September event is expected to fold those vehicles into the existing Robotaxi fleet within days of the launch.


Austin previously ran Robotaxi from 6 a.m. to 2 a.m. as of last September, a schedule set before the service expanded into Dallas, Houston, Miami, Tampa, Orlando and the Bay Area. Wednesday’s post did not specify whether that extended overnight window still applies in Austin specifically or whether 6 a.m. to 10 p.m. is now the standard across every market. Tesla’s post, visible on its official Robotaxi account, framed the change simply as fewer riders waiting around for a car.

Whether the wider hours hold once Cybercab enters the fleet next week is the next thing worth watching. Tesla has tended to expand Robotaxi in increments, first geofence, then hours, then fleet size, and each step so far has arrived without much advance notice.
