Elon Musk talks upgrades after SpaceX Starship launches, explodes in midair
SpaceX has completed its fourth Starship test flight in as many months, offering the latest glimpse into the often frustrating reality of a highly iterative, hardware-rich rocket development program.
Right on schedule, SpaceX Starship prototype serial number 11 (SN11) lifted off from Boca Chica, Texas at exactly 8am CDT (UTC-5) – all but completely cloaked in a thick layer of fog. While unfortunate for any unofficial observers (and possibly SpaceX’s own desire to gather video footage of a test flight), SpaceX has experience launching rockets (namely Falcon 9) in thick fog thanks to its Vandenberg Air Force Base launch site on the California coast.
As such, fog theoretically poses no fundamental threat to rockets like Starship, but SN11 still took the opportunity to explore new and exciting failure modes shortly before touchdown. CEO Elon Musk himself didn’t take long to weigh in and has even offered some details and a schedule for upgrades planned for SpaceX’s next-generation launch vehicle – upgrades hoped to alleviate whatever issues led to Starship SN11’s premature demise.
First and foremost, due to the fog, the general public saw virtually nothing throughout the launch attempt. Remote streaming cameras set up near SpaceX’s launch facilities – now, excitingly, with the company’s own permission – did manage to catch some level of detail, providing the bare minimum level of insight needed to speculate on SN11’s failed landing attempt.
Per an official webcast and NASASpaceflight’s unofficial “Danger-Close Camera,” installed a few hundred feet from the launch site with SpaceX’s permission, Starship lifted off at exactly 8am and had a seemingly nominal ascent, reaching a familiar 10 km (6.2 mi) apogee around four minutes later. SN11 then arced over onto its belly and free-fell for ~100 seconds. Aside from a few intermittent fires burning on some of the rocket’s three Raptor engines, not an uncommon sight since SN8 first flew, nothing appeared particularly out of the ordinary.
At T+5:49, however, things rapidly went wrong. Still belly-down, Starship SN11 attempted to reignite all three of its Raptor engines to propulsively flip into a vertical landing position. After at least one seemingly successful reignition, SpaceX immediately lost onboard video and telemetry feeds. Based on NASASpaceflight’s pad-adjacent camera, a substantial explosion followed one or two seconds after that attempted ignition, ending Starship SN11’s test flight around 20 seconds earlier than any of its three late siblings.
Debris began to visibly hit the ground another 5-10 seconds after that explosion was first heard, all but guaranteeing that Starship SN11 exploded in midair. At this time, it’s impossible to know what exactly went wrong, but there are two clear possibilities. Starship SN11 could have failed to reignite two or even all three Raptor engines, triggering onboard flight termination system (FTS) explosives designed to prevent the rocket from straying beyond a safe zone of operations. More likely, Starship suffered a substantial failure during that reignition and flip attempt, triggering an almost immediate explosion that tore the rocket apart around half a kilometer (~1500 ft) above the pad and landing zone.
Shortly after, Musk said that Raptor “engine #2 had issues on ascent” that were notable but not enough to explain a violent midair failure and confirmed that whatever went wrong came “shortly after landing burn start.”
Musk offers Starship upgrade schedule, details
Having suffered a failure a bit less than six minutes after launch, Starship SN11 – the fourth three-engine, high-altitude prototype – was ironically the farthest from a successful landing before something went wrong: one step forward, two steps back. While unfortunate, SpaceX still got some amount of data and uncovered one or several new failure modes – arguably the two of the most important primary goals of any developmental flight test program.
Further, Musk revealed that SpaceX intends to complete and roll Starship SN15 to the launch pad just “a few days” from now – certainly earlier than expected. While the SpaceX CEO didn’t go much into detail, he reaffirmed that SN15 would bring substantial upgrades, stating that “it has hundreds of design improvements across structures, avionics/software, & engine[s].”
Musk also touched on SpaceX’s near-term plans after SN15’s upgrade path, confirming that Starship prototypes from SN20 onwards will be “orbit-capable” with even more improvements. That seemingly delineates three clear ‘blocks’ of Starship prototypes, beginning with SN8 through SN11, proceeding with SN15 through SN19, and (nominally) gearing up for true orbital-class test flights with prototype SN20 and its successors. All told, SN11’s midair demise appears likely to be just a small blip in front of a jam-packed, well-structured series of Starship upgrades and flight tests just over the horizon.

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.
Tesla Optimus Gen 2.5 vs Gen 3 comparison via @WholeMars on X
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.
