SpaceX launch technicians and engineers have officially completed the integration and static fire testing of the second Falcon Heavy rocket ever, nearing the end of preflight preparations for the vehicle’s critical commercial launch debut.
Carrying the commercial communications satellite Arabsat 6A, the rocket will be tasked with placing the massive spacecraft into a high-energy geostationary orbit. After a combination of hurdles and conflicting priorities conspired to delay Arabsat 6A’s launch from mid-2018 to February, March, and eventually, April of 2019, both the spacecraft and rocket are nearly ready to go. If all goes as planned, SpaceX will also complete the first successful launch and near-simultaneous landings of three independent rocket boosters, preparing two of the three boosters for reuse on a launch that could happen as early as June 2019.

Falcon 9 Block 5, meet Falcon Heavy
- With this Falcon Heavy, SpaceX has effectively built – once again – a center stage that is nearly its own rocket, much like the tortured development of the first vehicle’s center stage can be blamed for a lot of its years of delays.
- Based on Falcon 9 V1.2’s Block 3 iteration, Falcon Heavy Flight 1’s center core was effectively outdated a year before it launched, and Falcon 9 Block 5 debuted just three months after its first and last launch.
- Combined with the center core’s untimely demise when it crashed into the Atlantic after running out of engine starter, the now 14 months separating Flight 1 and Flight 2 of Falcon Heavy can be explained by the rocket’s delayed path to the launch site.
- By the time the first Falcon Heavy’s main components were all present in at the launch site, SpaceX was already building Block 5 rockets and was as few as three months away from completely transitioning its Hawthorne, CA factory to Block 5.
- Due to the extensive changes in production incorporated into Block 5, this was effectively a no-turning-back deal where the cost of transitioning back was simply a non-starter.
- By the time Falcon Heavy had launched, and its center core had smashed itself to pieces on the Atlantic Ocean surface, it was far too late to begin producing a replacement copy. One step further, the process of ramping up Block 5 production had been slowed significantly by the drastic changes made across the board, taking SpaceX to the edge of production-related launch delays over the course of 2018.
- Put simply, building two side boosters and a relatively boutique Falcon Heavy center core – all three of which would be inextricably tied together for the foreseeable future – was not a practical option when three separate Falcon 9 Block 5 boosters could instead support 6-12+ launches over a period of six or so months.

(Hopefully) the first of many
- In the nominal event that SpaceX’s second Falcon Heavy launch is an unqualified success, it’s entirely possible that the doors to new markets could be opened as the world and its many spacefaring customers begin to contemplate the existence of an affordable super-heavy-lift launch vehicle – the first of its kind.
- On the outside, Falcon Heavy can begin to look like a bit of a boondoggle from a business perspective. It will have probably cost no less than $750M-$1B to develop, including the Block 5 modifications needed, and likely brought in less than $100M in gross revenue. It’s a black hole that SpaceX currently dumps huge volumes of cash into, in other words.
- However, this sort of observation is far too pessimistic and gives SpaceX far too little credit after some additional careful analysis. As of today, SpaceX has six public launch contracts for FH, two of which are from the USAF/NRO and likely valued around $130M-$150M.
- Purely commercial contracts for Falcon Heavy will probably be closer to $90M-100M, more than competitive with rockets like Atlas 5, Delta IV Heavy, Ariane 5, and other future vehicles like ULA’s Vulcan.
- Within ~12 months, the USAF will likely have awarded 10-16 additional launch contracts to some combo of Falcon 9 and Falcon Heavy as part of the latest EELV (now NSSL) acquisition phase. Assuming SpaceX is one of the two providers chosen, Falcon Heavy could receive numerous additional contracts for heavy military satellites.
- Additionally, NASA is now seriously considering Falcon Heavy for the launch of flagship missions like Europa Clipper and (maybe, maybe not) even Orion missions to the Moon.
- Falcon Heavy could also be the only vehicle in the world with the performance needed for a number of other missions that could arise from the Lunar Gateway, including launching actual segments of the space station and launching deep space cargo missions resupply said Gateway.
- Only ULA’s Delta IV Heavy can marginally compete with Falcon Heavy’s performance, but it typically costs no less than $300M per launch, a 2-3X surcharge over SpaceX’s offering. Due to the utter and complete lack of competition from both a price and performance perspective, SpaceX could essentially have the heavy life market cornered for something like 48-60+ months.
- Offering a unique product with potentially high demand and no real alternative, SpaceX would not be out of place to raise its profit margins significantly, helping to rapidly pay back the capital investment it put into Falcon Heavy’s extended development.
- Regardless, the future of Falcon Heavy has every right to be even more thrilling and diverse than the already impressive Falcon 9.

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 integrates Grok Bot into its vehicles for the ultimate personal assistant
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
Grok Bot makes things much easier across your entire life. From the Tesla, I’ve used it to place pickup orders for my Fiancée and I, we’ve ordered groceries… https://t.co/ZJSLieG1s5

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.
