SpaceX’s massive Falcon Heavy rocket aims for December 29 inaugural launch
Based on information released by NASASpaceflight.com, a highly reliable source of insider details, SpaceX’s first Falcon Heavy rocket could roll out to the LC-39A launch pad before the end of November, less than a month away. While the first roll-out (or two) will be dedicated solely to “Wet Dress Rehearsals” (WDR), this will be the first time the iconic vehicle makes it to the pad, and will be a historic event regardless of what follows.
No earlier than (NET) “late-November”, the first WDR will see Falcon Heavy go through the usual motions of propellant loading while also conducting an array of systems checks and validations to verify that things are proceeding as expected. This first test will not culminate in any sort of hot-fire, and is more intended to verify that the massive rocket is playing well with the modifications made to the launch pad and the Transporter/Erector/Launcher (TEL) that carries it from the integration facilities to the pad. If major issues come up, they will be dealt with and followed by a second identical WDR. If there are no issues with the first WDR, the second rehearsal could smoothly morph into the first static fire of the integrated vehicle.
As Chris Gebhardt of NSF discusses in some detail, the first Falcon Heavy static fire(s) conducted at LC-39A will be of groundbreaking importance, as SpaceX is currently unable to test fully-integrated Falcon Heavy vehicles at its McGregor, Texas facilities due to the rocket’s sheer power. A lot, thus, rests on these first static fires, currently scheduled to begin around December 15th.

Given the distinctly experimental nature of Falcon Heavy’s inaugural launch, specific dates are best taken as general placemarkers, and the actual dates of the first flow depend entirely upon the tests that precede each subsequent step. Nevertheless, the dates provided by NASASpaceflight point to Falcon Heavy’s first static fire on December 15th, followed two weeks later by a tentative launch date of December 29th.
Staying focused on Mars: Is Falcon Heavy necessary?
Even an uncertain launch date of that specificity is still a historic event for Falcon Heavy, long lampooned and straw-manned as an example of SpaceX’s silly pie-in-the-sky claims and Elon Musk’s oversimplification of complex engineering tasks. There is a grain of truth to such contentions, but they tend to miss the point by huge margins. The actual market for mid-level heavy-lift launch vehicles like Falcon Heavy is quite simply too small to be a major motivator for a commercial launch company like SpaceX. One must remember that SpaceX was not founded to be a run-of-the-mill launch provider. The company’s goal, as has been reiterated ad infinitum, is “enabling human life on Mars”, something that has explicitly prefaced every single job posting on the company’s website for more than half a decade.
For a time, it appeared that Falcon Heavy might eventually be used to enable SpaceX’s Red Dragon program, intended to field-test the technologies needed for month-long cruises in deep space and landing large payloads on Mars. However, the program was cancelled earlier this year, in favor of what Musk called “vastly bigger ships”. Indeed, updated Mars plans unveiled on September 29th showed that SpaceX was forging ahead with an updated BFR and BFS, and hopes to fly its first missions to Mars in 2022.

Falcon Heavy will admittedly become the most powerful operational launch vehicle when it first lifts off in approximately two months, and it will likely retain that title well into 2020, when NASA’s Space Launch System may conduct its first launch. However, regardless of the impressive technological accomplishments it will embody, Falcon Heavy simply is not powerful or affordable enough to ever realistically enable a sustained human presence on Mars. SpaceX does have a small number of customers actively waiting with payloads for Falcon Heavy – its second mission is currently penciled in for June 2018 – and it is reasonable to assume that some or all of those missions will be completed simply out of due diligence. SpaceX may also be motivated to continue the Falcon Heavy program as a possible entrant in a recently-announced USAF competition meant to partially fund the development of multiple US-built heavy-lift launch vehicles.
More simply still, experience derived from igniting and simultaneously operating Falcon Heavy’s 27 Merlin 1D rocket engines will to some extent benefit BFR’s development and operations, as the conceptual vehicle is currently expected to host 31 Raptor engines on its first stage.

Whether Falcon Heavy is to remain a development or production priority for SpaceX after its first several launches is unclear, but the vehicle’s inaugural launch and all subsequent launches are bound to be spectacles to behold. The company’s second Florida-based launch pad, intended to support two simultaneous landings of Falcon Heavy’s side boosters, appears to be nearly complete. At LC-39A, the facility’s TEL already sports major visible modifications necessary for it to operate with Falcon Heavy. All three of the first Heavy’s first stage cores have already completed hot-fire testings in Texas and are now located at Cape Canaveral, awaiting their first integrated tests later this month. Delays to the December 29th launch date are probable, but the various components needed for Falcon Heavy’s first launch have truly come together, and the vehicle’s launch is now simply a matter of “when”. Place your bets!

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.
