Update: On March 15th, SpaceX got within milliseconds of Starship serial number 11’s (SN11) first Raptor engine test but suffered an abort just before full ignition, briefly leaving the rocket on fire.

Around 12:26 pm CDT, after an otherwise nominal static fire flow, Starship SN11 momentarily ignited one or two of its three Raptor engines’ preburners, referring to a central component that burns cryogenic liquid propellant into gas that’s ready for combustion. As with all preburner tests, intentional or otherwise, the end result looked a bit like a weak static fire and produced a small but visible amount of flame and thrust. Unlike intentional preburner tests, the static fire abort seemingly ignited something hidden inside Starship SN11’s and appeared to burn for at least another 30-40 seconds.

Starship SN8 intentionally performed a preburner test representative of SN11’s abort back in October 2020.

Raptor has proven itself to be an extremely durable engine, up to and including surviving visible onboard fires during actual Starship flight tests. Nevertheless, depending on the source of SN11’s post-abort fire and what it may or may not have burned or damaged, it’s no surprise that SpaceX ended testing for the day instead of quickly trying again, which it’s done several times prior. If the fire was largely harmless, SpaceX has already distributed notices suggesting a second attempt could happen as early as 6am to 12pm CDT (UTC-5) on Tuesday, March 16th. If more time is needed, SpaceX has the rest of the week to conduct any necessary repairs or swap out SN11’s Raptor engines.

Public documents show that SpaceX has plans to static fire and launch its latest Starship prototype within a two-day period that could begin later today.

SpaceX shipped Starship SN11 from its Boca Chica, Texas rocket factory to test and launch facilities a mile down the road on March 8th, less than five days after Starship SN10 exploded minutes after touchdown. The very next day, SpaceX completed ambient-temperature proof testing, filling Starship with benign nitrogen gas to check for leaks and verify system health. Two days after that, Starship SN11 appeared to complete a several-hour cryogenic proof test – swapping nitrogen gas for its supercool liquid form – without issue.

Despite the seemingly successful ‘cryo proof,’ something prevented a subsequent static fire test planned on March 12th before any attempt could be made, delaying the next attempt until after the approaching weekend. An agreement between SpaceX, Cameron County, and the state of Texas currently prevents road closures (and thus rocket testing) on weekends falling between Labor Day and Memorial Day, rules meant to preserve some level of public access to Boca Chica Beach.

As a result, unless SpaceX is already ready to launch (it has waivers for three such weekend closures for launch attempts), the company has to wait until Monday even if a minor issue fixable in hours or a day or so scrubs Friday test plans. While inconvenient, it’s worth noting that the existence of that public beach and the strong regulations that protect its public domain is likely one of the only reasons the general public can still get as close as they can to SpaceX’s Boca Chica ‘Starbase’.

For whatever reason, that road closure agreement does still mean that SpaceX will (in theory) be able to test and launch any day of the week from May 31st to September 6th, save for a few holidays, effectively boosting the number of opportunities by 40% for those 14 weeks. Until then, SpaceX is doing everything it can to take full advantage of the five days a week it is allowed to test Starship prototypes. N

Notably, although Starships SN8 and SN9 both hit a few weeks of technical and regulatory snags while preparing for their high-altitude launch attempts, SpaceX has been gradually speeding up that process over time. Starship SN10, the first prototype of its kind to land in one piece, took just 33 days to go from pad arrival to liftoff and spent just 8 days between its first static fire and launch attempts. The same feats took Starship SN8 77 and 50 days, respectively, with SN9 splitting the difference at 43 days from transport to liftoff and 28 days between its first static fire and launch attempts.

Road closure requests, a safety warning for residents, and a Temporary Flight Restriction (TFR) filed with the FAA all suggest that SpaceX’s current plan is to attempt Starship SN11’s first triple-Raptor static fire between 6am and 12pm CDT on Monday, March 15th. If that test goes almost perfectly, SpaceX wants to turn the rocket around for a 10 km (6.2 mi) launch attempt on Tuesday, March 16th – the very next day. Given the past performance of high-altitude Starship prototypes, that target is decidedly ambitious and likely to incur delays, but it still reveals the true scope of SpaceX’s goals even at this early stage of development.

If Starship SN11 does manage to launch within a few days of its first static fire attempt, SpaceX would still crush SN10’s 33-day record by a factor of three. Stay tuned for updates on Monday’s possible Starship static fire and rapid Tuesday turnaround attempt

Sweden blocks Tesla FSD-style testing in Stockholm

It looks like FSD testing in Sweden would have to wait some time.

Tesla is putting a lot of effort into getting its Full Self Driving (FSD) system approved in territories outside North America. But while China seems to have embraced FSD fully, other countries like Sweden do not seem to be receiving Tesla’s automated driving system very well.

This became quite evident in a document from Stockholm City, which has started making the rounds online.

FSD Testing Rejected

The document, which was initially shared by X user @KRoelandschap, indicated that the Swedish Traffic Department in Stockholm had rejected Tesla’s request to start FSD testing in the city’s streets. Tesla has been demonstrating FSD in several areas across Europe, so it is not surprising that the company is also attempting to test its automated driving system in Sweden.

Unfortunately for Tesla, Sweden might prove to be a tough nut to crack. As per the City of Stockholm: 

“The Traffic Office is currently working on updating its approach to automation. At the same time, the city and the office are under heavy pressure from other ongoing innovation tests. Our ambition is to actively participate in and learn from the continued development in the field of automation.

“Based on this, and in combination with the fact that the current test is the first of its kind, which entails certain risks for both infrastructure and third parties, and that it is planned to be carried out throughout the city, the City of Stockholm considers it is currently not possible to approve the implementation of the test.”

Tesla’s Other Swedish Troubles

Sweden’s FSD testing rejection is not the only roadblock facing Tesla in the country. Since October 2023, Swedish unions have been engaged in an active effort to disrupt Tesla’s operations. The unions’ efforts have been varied, with some resulting in Tesla having difficulty launching more Superchargers in Sweden. Despite this, Tesla has remained stubborn and has refused to bow to the unions’ demands.

Fortunately for Tesla, it seems like its numbers are still strong. Despite the company’s decline in several European countries, the new Model Y is starting to see strong sales figures in Sweden. In early May alone, the new Model Y became the country’s most popular electric vehicle—a notable accomplishment considering the unions’ active efforts to disrupt Tesla.

Tesla firmware shows new Model Y seat configuration is coming

Tesla could be adding another seating configuration beside the seven-seater to the Model Y lineup later this year.

Tesla firmware has been a great place for some to reveal what the company has in the pipeline, and a new seating configuration for the best-selling Model Y looks to be on the way.

Last week, we reported that Tesla was already hinting toward a 7-seater configuration of the Model Y in a promotional email it sent to those on its contact list.

However, firmware revealed by Tesla hacker greentheonly is showing that a new seating configuration is on the way — a six-seater:

Green says the configuration would not be available in China-only, and will be potentially for sale in other markets as well.

The six-seat and seven-seat configurations of the Model Y were available in the Legacy version of the vehicle, but were met with mixed reviews, as many complained about the lack of legroom in the third row.

This was something that was a real concern for many of those owners who needed something larger than the traditional five-seat variant, but did not want to buy the much more pricey Model X.

We’ve covered the size of that third row on several occasions.

Some owners even took the idea of having a seven-seater into their own hands:

Tesla did not explicitly announce a six-seater configuration of the Model Y, but Lars Moravy, the company’s VP of Vehicle Engineering, said the seven-seater would come to production later in 2025.

Tesla confirms massive hardware change for autonomy improvement

Tesla has confirmed that a recent change made to some of its recently refreshed vehicles is, in fact, a strategy it will use to improve its suite as it continues to work toward autonomy.

Tesla has confirmed that a recent change made to some of its recently refreshed vehicles is, in fact, a strategy it will use to improve its suite as it continues to work toward autonomy.

Tesla first introduced a front-facing camera on the front bumper with the Cybertruck.

Then, the Model Y “Juniper” received the hardware update. The Model S and Model X both received the front-facing camera with its latest update, which was officially revealed last week.

Tesla used new language with the release of the front-facing cameras on the Model S and Model X, confirming they will assist with several things, including “using Autopilot and Actually Smart Summon capabilities”:

“Enhanced visibility when parking or using Autopilot and Actually Smart Summon capabilities.”

This tiny feature on the new Tesla Model Y is perhaps its biggest addition

This is the first time Tesla has used this sort of language, as it was a completely different description with the launch of the new Model Y in January.

When Tesla launched this vehicle, it said the front bumper camera “provides a wider field of view for automatic assisted driving and advanced Smart Summon.”

Tesla switched from using cameras and sensors to only cameras with the launch of Tesla Vision several years ago. The company’s utilization of cameras comes from Tesla’s belief that Ultrasonic Sensors (USS) are not needed for self-driving efforts:

“Along with the removal of USS, we simultaneously launched our vision-based occupancy network – currently used in Full Self-Driving (FSD) (Supervised) – to replace the inputs generated by USS. With today’s software, this approach gives Autopilot high-definition spatial positioning, longer range visibility and the ability to identify and differentiate between objects. As with many Tesla features, our occupancy network will continue to improve rapidly over time.”

CEO Elon Musk has said that sensors were only a crutch and that self-driving would be solved through the use of cameras:

“When your vision works, it works better than the best human because it’s like having eight cameras, it’s like having eyes in the back of your head, beside your head, and has three eyes of different focal distances looking forward. This is — and processing it at a speed that is superhuman. There’s no question in my mind that with a pure vision solution, we can make a car that is dramatically safer than the average person.”
