Elon Musk says SpaceX’s orbital Starship debut headed for FAA faceoff in a few weeks
CEO Elon Musk says that SpaceX’s first completed Starship rocket could be ready for its orbital launch debut just “a few weeks” from now – far sooner than most expected.
On August 6th, SpaceX very stacked that same vehicle – Starship 20 (S20) and Super Heavy Booster 4 (B4) – to its full height for the first time ever, briefly creating the largest rocket ever assembled. However, the feat was equally a symbolic photo opportunity. SpaceX did install an unprecedented number of Raptor engines on Booster 4 and Ship 20 in a spectacularly short timeframe and both stages are technically meant for flight, but Starship S20 was demated less than an hour later and shipped back to the factory shortly thereafter.
Though they’d had Raptors installed and been stacked to their full ~120m (~390 ft) height, neither booster or ship were truly complete and at least 20% of their engines had yet to be qualified at SpaceX’s McGregor, Texas test campus. Both needed a week or two of additional work – mostly just wiring avionics and installing secondary and tertiary plumbing. Curiously, on August 13th, Starship S20 was once again rolled to SpaceX’s Boca Chica launch site in a partial state of completion, where it now sits beside the orbital launch mount for unknown reasons.
After several days of delays, SpaceX also removed Super Heavy B4 from the orbital launch mount and returned it to the build site on August 11th, where teams are still working to finish its secondary plumbing and avionics. Like Ship 20, all of its Raptors were removed soon after its return, freeing both to complete cryogenic proof testing without risking dozens of potentially flightworthy rocket engines.
Like all previous Starship prototypes, those ‘cryo proof’ tests will involved loading Ship 20 and Booster 4 with supercool liquid nitrogen (LN2), simulating the weight and extreme thermal stress of real liquid oxygen (LOx) and methane (LCH4) propellant without the risk of a catastrophic fire or explosion in the event of anomalies.
For more than a month, SpaceX also gradually outfitted one of two suborbital launch mounts with special hydraulic rams that would have simulated the thrust of Ship 20’s three sea level and three vacuum-optimized Raptor engines – the first Starship prototype with such a configuration. The same was true for Booster 4 and SpaceX had outfitted a new test jig with nine hydraulic rams labeled “B4” – clearly meant to simulate the thrust of nine engines pushing against the Super Heavy’s thrust puck. Additionally, a far larger structural test tool unofficially nicknamed the ‘can crusher’ has been more or less finished after ~6 weeks of work, leading many to assume that Booster 4 would be the first Super Heavy to be subjected to the immense simulated thrust of 29 Raptor engines.
However, earlier this week, SpaceX completely disassembled the six hydraulic rams installed on Mount B and removed all nine rams from the apparent Booster 4 jig. Starship S20 was then rolled back to spot beside the orbital launch mount – not the suborbital mount that had been carefully prepared for its test campaign mere days prior. At the time, the only practical explanation – save for some kind of catastrophic miscommunication – was that SpaceX had cancelled clear plans to cryo proof Ship 20 and Booster 4 with simulated Raptor thrust.
Up to now, every single major design change implemented on Starship’s engine section has resulted in the first prototype – and often one or several test tanks – being subjected to cryo proof testing with a complex series of hydraulic rams used to simulate thrust. That most recently peaked with SpaceX’s lone BN2.1 Super Heavy test tank, which seemingly passed a cryo proof, pressure test, and a jig capable of simulating the thrust of up to eight Raptor engines. However, SpaceX has never tested Super Heavy’s new nine-engine thrust puck and has certainly never subjected a Super Heavy booster skirt to the combined thrust of 20 outer engines and 9 center engines.
The fact that complex custom test stands and jigs had already been assembled and installed for Ship 20 and Booster 4 before they were removed or disassembled without use strongly implies that someone at SpaceX – presumably Elon Musk himself – has either decided that those tests are unnecessary or that skipping them is worth the substantial risk. Indeed, for Musk’s subsequent August 15th claim that Ship 20 and Booster 4 could be stacked and ready for flight just “a few weeks” from now to come true, 14-21 days is simply nowhere close to enough time to cryo proof, thrust sim, and static fire both vehicles; integrate the stages; and perform the first true integrate testing of a Starship stack – possibly up to and including some combination of a full-stack cryo proof, wet dress rehearsal, or static fire.
And, as Musk himself notes, that complex ballet of first-of-their-kind rocket prototypes might not even be the long straw for Starship’s orbital launch debut. Technically, short of some kind of major legal intervention, there is actually no way for Starship to launch in the next “few weeks.” In an absolute best-case scenario, the Federal Aviation Administration (FAA) would release a draft environmental review of SpaceX’s orbital Starship launch site today, accept public comments for the required 30 days, instantly clear Starbase with environmental approval within a few days of the public comment window, and then approve Starship’s South Texas orbital launch license as soon as the necessary environmental permissions are in hand.
In other words, the best-case ETA of regulatory approvals for Starship’s first orbital test flight is arguably late September and going off of FAA precedent, that optimistic scenario is also a fairy tale. In reality, a bare minimum of 2-3 months after the FAA releases its draft environmental impact statement is a more realistic best-case scenario for SpaceX. On the opposite end, it’s possible that the FAA will decide that SpaceX needs to complete an entirely new environmental review for its Starbase launch site, easily delaying Starship’s orbital launch debut by 6-12+ months. That doesn’t even account for the potential looming challenges SpaceX might have to surmount to secure an orbital Starship launch license.
Given the challenges SpaceX had in securing even a watered-down suborbital launch license for its medium-altitude Starship flight tests, it’s not out of the question that the FAA could attach some extremely onerous limitations to that license. Ultimately, only time (and the slightest hint of actual movement or urgency at the FAA) will tell and there is arguably nothing that would better apply pressure in the right places than the largest, most powerful, most ambitious rocket ever built sitting – ready for flight – at a brand new launch pad, waiting solely on regulatory approval.

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.
