SpaceX shrugs off Starship implosion and gets back to work as Elon Musk talks next steps
SpaceX has shrugged off the catastrophic implosion of its first serial Starship prototype (SN01) and begun stacking sections of the next ship (SN02) while CEO Elon Musk talks next steps for the next-generation rocket program.
By now, it’s reasonably clear that the demise of Starship SN01’s tank and engine section came as a bit of surprise to SpaceX itself, while it assuredly shocked non-employees and local residents who happened to be watching on eve of the anomaly. CEO Elon Musk himself appears to have expected different results, noting that – thankfully – the likely source of the Starship’s unforeseen failure had already been determined.
Despite the apparent setback, it appears that SpaceX won’t have to wait long at all to continue its uniquely ‘hardware-rich’ Starship test campaign. With a workforce now several hundred strong and a great deal of hands-on and strategic experience gained from building Starships Mk1 and SN01, SpaceX is now practically churning out parts for future Starship SNxx prototypes. Most notably, Starship SN01’s predecessor is potentially just a few days away from being stacked into a finished tank section, hinting at the almost unfathomably speed that SpaceX is able to build full-scale vehicles even in early days of the program.
Three days after Starship SN01’s spectacular implosion and unintentional ‘launch’, SpaceX CEO Elon Musk took to Twitter to share a video captured by local Boca Chica Village resident ‘bocachicagal’ and posted by NASASpaceflight.com. Attached above, Mary’s video offers an incredibly vivid view of the rocket’s violent demise while further revealing the apparent location where the failure started – Starship SN01’s engine section and thrust structure.
Confirming suspicions, Musk quickly implied that the Starship’s failure originated in or around its thrust structure (‘thrust puck’), further noting that Starship SN02 – already in the middle of production – would be “stripp[ed]…to [the] bare minimum to test the thrust puck to dome weld.” In essence, it sounds like Starship SN02 will become SpaceX’s third intentional “test tank”, following in the footsteps of two small Starship tanks built and pressurized to failure to verify the quality of Starship manufacturing.
Starship SN02’s thrust structure design already appears to be a departure from SN01’s apparently unsuccessful iteration. Given that it was already partially completed before Starship SN01 failed during testing, it’s possible that SpaceX will attempt to reinforce the SN02 thrust structure, but the company may have already implemented upgrades before its engineers had the benefit of hindsight from February 28th’s test.
Regardless of what happens to Starship SN02, the fact that SpaceX is apparently building full-scale, (mostly) functional Starship tank sections from raw materials to the launch pad in a matter of a few weeks is incredibly encouraging for the next-generation rocket development program. As an external observer, it’s certainly disappointing to see an impressive piece of rocket hardware shredded in an evening after weeks of work, but that speed – and SpaceX’s willingness to accept failures at the scale of SN01 – suggests that each prototype is almost unfathomably cheap. Unofficial estimates peg the cost of SN01-like Starship prototypes at just several million dollars apiece, while the cost of the raw steel itself is so low that it might as well be negligible.
Even if it takes SpaceX 5-10 SN01-class failures to mature its South Texas rocket factory into a reliable machine and get to a point of stability and confidence with suborbital Starship flights, the total cost of that trial and error is comically insignificant relative to almost any other rocket development program in history. To be clear, SpaceX might benefit from going a little slower and refining Starship’s prototype design, but it’s impossible to know from an armchair. For now, the best available advice is to simply enjoy the show and view each potential test failure as just another small step along the path to Mars.

Tesla Optimus Gen 3 shows off a cleaner, factory-ready design in new app discovery
Renders hidden inside Tesla’s Android app show Optimus Gen 3’s design before any official reveal.

Tesla may have accidentally given a first look at its newest Optimus Gen 3 humanoid robot when photos were found in the Tesla smartphone app.
Design files tucked inside a recent Android version of the Tesla app appear to show the third generation humanoid robot next to the older Gen 2.5 prototype. The assets were extracted from the app package by Tesla community member @wholemars, who posted the renders on X late Tuesday night before deleting them. The Tesla Newswire reshared the side by side comparison on Wednesday, and the images have circulated widely since.

The files are labeled “gen3” and were built as models for Tesla app’s own interface, as validated directly by Grok to be official.
The comparison shows a robot that looks built for a factory line rather than a lab bench. Gen 2.5’s exposed mechanical linkages and gold plating on the knees and shins are gone. In their place, Gen 3 uses matte black fairings on the lower legs, paired with a more contoured champagne gold body. Flexible covers now seal the joint where the torso meets the upper thighs, keeping bearings and moving parts sealed from debris and unnecessary contact.
The body panels fit more tightly, and the hands, which Tesla has said carry 22 degrees of freedom, look far more refined than those on earlier units.
This most recent leak fills a gap Tesla has left open for most of the year. Elon Musk said on March 31 that Optimus 3 was walking around but needed “some finishing touches” before it could be shown, a delay Teslarati covered when Tesla missed its first quarter reveal target. Musk later said Tesla would hold the design back until closer to production, partly to keep competitors from copying it. No reveal date has been announced.
The app itself has been preparing for Optimus for months. In July, code in the Tesla app pointed to a dedicated robot phone key, a consent screen for collecting video and spatial data while Optimus works inside a home, and an alert system for low battery and mechanical faults. Finished 3D models of Gen 3 suggest the interface owners will eventually use is moving past placeholder code toward something Tesla intends to ship.
Manufacturing is moving in parallel. Tesla tore out the original Model S and Model X lines at Fremont this summer to make room for Optimus production, with a planned capacity of one million robots a year. At Giga Texas, the steel frame of a dedicated Optimus factory is nearing completion ahead of a targeted 2027 start, with Musk pointing to an eventual output of 10 million units annually.

Tesla Semi lands the biggest electric truck deal in U.S. history
Tesla leads a record 2,500 truck order, but not every truck will be a Semi.
Tesla has landed the largest electric truck order in U.S. history. ZET SCALE, a new alliance of shippers and carriers, named Tesla its primary manufacturer on Tuesday for an initial order of 2,500 electric Class 8 trucks. The deal alone would nearly double the number of electric heavy trucks operating in the country.
According to the press release from Catalyst Mobility, the nonprofit formerly known as CALSTART, Kenworth, RIDE and Volvo were also selected as secondary manufacturers that carriers can pick if their operations call for it. No split between the four brands has been published, so the exact number of Semis in the order is not yet known.

Tesla won the top slot through a competitive request for proposals. The alliance, which Catalyst Mobility runs with the Smart Freight Centre, scored bidders on price, range, charging capability and production capacity. Pooling freight demand from founding shippers, including Microsoft and PepsiCo, let every truck maker bid lower than it would for a single fleet. “The Tesla Semi is designed for lower cost per mile operations than diesel,” said Dan Priestley, director of the Tesla Semi program, as noted in the press release.
The financing is built to pull in carriers who have avoided electric trucks. ZET Financial is issuing the purchase order for all 2,500 units and will place them with fleets through a fair market value lease. The trucks will be deployed over the next few years across 10 freight hubs in Los Angeles, Stockton, Bakersfield, Seattle and Tacoma, Houston, Dallas, San Antonio, Chicago, Atlanta, and the Newark and New York area. ZET SCALE says the first order is only the opening round, with a longer term goal of 10,000 trucks or more.
Even if Tesla ends up with only a majority share, it would still be the biggest Semi deal to date. Einride’s 500 unit order in August was the previous record, and WattEV’s 370 truck order in May was the largest California deal at the time. Einride’s CEO has since said he expects all 500 trucks delivered by the end of 2027.
The announcement lands two days before Tesla formally inaugurates its Semi factory in Nevada on September 24. The 1.7 million square foot plant sits next to Gigafactory Nevada’s 4680 cell lines and is designed for 50,000 trucks a year.
Tesla has expanded Grok from an in-car chatbot into a hands-free work assistant. On September 22, Tesla officially launched Grok Bot capability, confirming that drivers can now manage email, calendars, files, chats, and tasks by voice and then hand more ambitious errands to the AI-fueled productivity cheat code.
Grok itself is built by xAI. The new car features split into two layers: Connectors link Grok to outside accounts. Grok Bot, currently limited to SuperGrok Heavy subscribers, can complete multi-step tasks such as placing a usual coffee order, booking a reservation, or scheduling an appointment. It truly puts the driver in a nearly complete hands-free driving and productivity setting, with ironically the only task truly requiring your hands being to touch the “Start Self-Driving” button.
We were granted access to Grok Bot’s Tesla integration a few weeks back, and we’ve been able to do a handful of things with it. On a handful of occasions, we’ve used it to order food and have it ready for pickup slightly later into the evening; we’ve managed to pick up groceries after a day of errands with Grok Bot, and outside of the car, it’s helped with budgeting and even my fantasy football draft.
We’ve been using @Grok Bot in Tesla for a few weeks after gaining Early Access, which we thank the awesome engineers for

Tesla shows another way to utilize it: in their demo, a driver says “Hey Grok,” asks the assistant to check an inbox, and hears that a message concerns a weekend reservation. Grok then scans the calendar, reports no conflicts, and confirms the Tahoe trip is clear. It can also add check-in details to a road-trip itinerary. The point is not novelty chat. It is keeping eyes on the road, or on Full Self-Driving, while the car handles the paperwork of a trip:

This Grok rollout is not a gadget add-on as much as it is Tesla’s thesis in software form: the car should stop being a machine you operate and start being a room you occupy.
Connectors and Grok Bot treat the cabin as an office that happens to move, and that has truly been Tesla’s intention for years now. The car has slowly become an extension of a home more than a vehicle. Inbox, calendar, groceries, takeout, and reservations become voice work, not dashboard chores that you need to do before you get in your car.
Responsibility shifts from the driver to the stack, and as many Tesla owners rely on FSD for travel, Grok Bot now handles the monotony of dinner reservations or appointments.
