Update: Right on schedule, SpaceX has transported Starship serial number 15 (SN15) from its Boca Chica rocket factory to a launch and test site just down the road.

SN15’s pad arrival comes just nine days after Starship SN11 – the last in a batch of four first-generation prototypes – exploded in midair some 30 seconds before a planned landing. While minor, SN11’s midair failure was undoubtedly a step backward relative to Starship SN10, which (briefly) became the first full-size prototype to land in one piece less than a month prior. Both SN8, SN9, and SN10 made it further into their identical flight tests, leaving SN11 somewhat high and dry and putting extra pressure on Starship SN15.

After Starship SN8’s unexpectedly successful December 2020 test flight, in which the rocket made it just a dozen or so seconds away from soft landing after more than six minutes in flight, SpaceX made the decision to scrap Starship SN12 and kill SN13 and SN14 before assembly could begin. Effectively a gamble that SN8-SN11 would produce enough of a foundation for future testing to start off on, it’s hard to say if that gamble paid off.

All four Starship flights managed the extraordinary feat of more than four minutes of powered flight and spent two minutes free-falling like no rocket ever before them, but they also made it clear that both Raptor and autogenous pressurization (using gasified propellant to pressurize Starship’s tanks) are not quite mature enough for reliable launches and landings. Featuring “hundreds of improvements,” many of which were hopefully designed to tackle some of those shortcomings, it’ll be up to Starship SN15 to attempt to carry that torch forward – and, with any luck, further than any prototype before it.

After SpaceX unexpectedly used a Monday road closure to deliver its first custom-built rocket fuel tank, plans for the next Starship test campaign and launch have begun to solidify.

Most importantly, the initial schedule for Starship serial number 15’s (SN15) test campaign appears to be clear. As of Wednesday, April 7th, road closures filed by SpaceX suggest that the first of a new group of upgraded Starships will be transported from build site to launch pad as early as 11am-1:30pm CDT (UTC-5) on Thursday, April 8th. Once SN15 is installed on ‘Suborbital Pad A,’ SpaceX means to waste no time and has scheduled a 7am-12pm road closure on Friday.

As usual, the weekend will once again be free of any testing or activity requiring road closures, but SpaceX has already cordoned off noon to 8pm on Monday and Tuesday (April 12/13) to continue putting its newest Starship prototype to the test.

While road closure notices no longer offer any real detail, a few basic details can still be inferred. The April 7th closure, for example, warns that SpaceX only plans to intermittently close the highway but not Boca Chica Beach – implying that the window poses no threat to residents or beachgoers. Historically, that means that something will be transported – likely Starship SN15, in this case.

On Friday, SpaceX has scheduled a full five-hour closure of both the highway and beach, implying that some kind of testing is likely on the books. The same goes for Monday and Tuesday, but with longer eight-hour closures.

More likely than not, assuming Starship SN15’s pad transport and launch mount installation goes smoothly, SpaceX will use the shorter Friday window to complete a basic ambient pressure test – filling the rocket with ambient-temperature nitrogen gas to test its complex plumbing and propellant tanks for leaks. Continuing the IFF (if and only if) string, SpaceX will then spend the weekend preparing Starship SN15 for a cryogenic proof test and thrust structure stress test – simulating the thrust of three Raptors after loading the rocket with extremely cold liquid nitrogen (LN2).

SpaceX will then most likely spend another one or two days inspecting Starship SN15 and removing the hydraulic ram used to simulated thrust from the launch mount the ship is installed on. Once SN15 and its mount are cleared, SpaceX can move into static fire testing. Given that – according to CEO Elon Musk – SN15 will debut Raptor engines with an unknown degree of upgrades, it’s reasonable to assume that SpaceX will take things relatively slowly and possibly perform more than one static fire test even if the first attempt is a total success.

If not and SpaceX continues to push hard like it did with SN10 and SN11, it’s not out of the question that Starship SN15 will be ready for its first launch attempt around Friday, April 16th or Monday, April 19th. Stay tuned for updates as SpaceX hopefully rolls the rocket to its Boca Chica, Texas launch site later today.

Tesla Model Y L gets suspension complaints in over odd issue China

Published

The Tesla Model Y L is arguably the most hyped trim of the all-electric crossover, other than the Performance configuration that comes with white-knuckle speed and sports car-level handling.

However, it is not all perfect. Tesla owners in China who took delivery of the Model Y L, denoted with an L to highlight its longer wheelbase, are experiencing what they are referring to as “collapsing” of the rear wheels, as suspension issues appear to be an issue with some of the builds.

The gap between the wheel arch and tire has narrowed to the point that “not even a single finger” could fit, according to a report from Car News China. The failures are not tied to a specific mileage, as one owner said that after just 9,000 kilometers (5,600 miles), they noticed the suspension issue when their car was fully loaded.

Another one had the issue at 30,000 kilometers (18,640 miles) and noticed that the wheel gap shrank to two fingers, so not as drastic as the person who reported a similar issue at 9,000 km.

Tesla Model Y L is gaining momentum in China’s premium segment

Along with the visual recognition of the issue, others are saying the sagging is causing abnormal wear on the inside of the tires. Extra weight and instant torque already provide additional stress on the tires in electric vehicles during normal operation, so it is no surprise that this is another complaint.

There has been no recall issued by Tesla, and the company has not yet publicly acknowledged the issue.

Some are suggesting that owners use a “finger test” to self-diagnose whether there is an issue with the suspension. There should be four fingers between the tire and the wheel well; anything less than that starts to get dicey.

Tesla Cybercab event gains steam ahead of massive launch

Published

Tesla is starting to truly tease and hype its groundbreaking Cybercab event, which takes place tomorrow in Austin, Texas. It will be the first time members of the public will be able to ride in a Cybercab, a vehicle without any manual controls, on public roads.

Tesla has been dropping some hype on X over the past several days, but this morning, the excitement has truly started to build up for the event. Although Cybercab has been unveiled before, this is truly Tesla’s announcement that it is ready to start offering autonomous rides for public passengers in its new ride-hailing-geared vehicle for the first time.

The hype has started with a variety of different social media posts that are a true indication that Tesla is preparing for something big. Teasing so much of the potential of Cybercab, including its ability to truly revolutionize how people hail rides for local travel, is what the big idea for the event entails. The time that many Tesla owners, fans, and investors have been waiting for is potentially here:

The event has remained slim on details. Even invitees are still awaiting true details about what the event will entail, where they’ll go, and what is in store for the evening. This is pretty typical for an event run by Tesla; they keep things under wraps for the most part until the very last minute.

However, there is no secret about what the real intention of Tesla is for this event: it is going to be a huge reveal party for a vehicle that has no steering wheel and no pedals. It is a truly massive step for the company moving forward.

Speculation persists as to whether this is going to be an event that simply announces that rides will begin with the Cybercab, or it will be something more substantial. Tesla has said in the past that they plan to sell the Cybercab to the general public in what could become a great way to earn passive income by adding it to a more global fleet of Robotaxi-geared vehicles.

Tomorrow, the show begins in Austin, and the Cybercab goes live at some capacity; we just don’t know exactly how quite yet.

SpaceX tells the FCC that Starship Flight 14 is going to orbit

SpaceX filed with the FCC for Starship Flight 14, its first true orbital launch attempt.

Published

By

SpaceX has asked the Federal Communications Commission for permission to fly Starlink terminals during Starship’s fourteenth flight test, and the filing lays out a genuine trip to orbit, something the program has never attempted.

Every Starship flight so far, including Flight 13’s successful splashdown in the Indian Ocean on July 24, has flown a suborbital arc that ends with the ship reentering the atmosphere within the same hour it launches. The FCC paperwork describes a mission profile built around an actual orbital insertion instead.

The payload is the other half of the story. Flight 13 carried 20 production Starlink V3 satellites, but because that mission never reached orbit, the satellites reentered along with the ship rather than joining the constellation, something Teslarati covered in detail after SpaceX released footage shot from one of those satellites as it drifted away from Starship in space. Flight 14 is designed to close that gap. If the orbital insertion holds, the roughly 20 V3 satellites onboard would separate into an operational orbit and could eventually go into service, each one rated for about 1 terabit per second of downlink capacity by SpaceX’s own account.

SpaceX announces new Starbase for ‘thousands of Starship launches annually’

Elon Musk first flagged the orbital attempt during SpaceX’s August 4 earnings call, the company’s first as a public entity following its June IPO under the ticker SPCX. He also floated catching the ship with the Starbase tower on the same flight, an idea he walked back on August 20, saying the catch attempt would more likely come “in a few months,” as Teslarati reported at the time. Flight 14 will instead target a splashdown for the ship in the Indian Ocean, the same recovery method used since Flight 12.

Hardware has been catching up to the ambition. Booster 21 completed a full 33-engine static fire on August 28, and Ship 41 finished its own six-engine test the week before. An airspace briefing circulated to pilots on August 20 listed September 15 as the target date, later than the end of August window Musk mentioned on the earnings call, though SpaceX has not confirmed a launch date publicly and Starship schedules routinely slip while hardware and FAA paperwork line up.

The FCC filing itself does not guarantee a launch date. It covers communications authority, and not flight readiness, considering SpaceX still needs Ship 41 fully stacked and cleared by the FAA before Flight 14 can fly. But the filing is a real marker of intent and it puts a specific regulatory process behind what had so far only been Musk’s word on the earnings call.
