SpaceX test-fires Falcon 9 for expendable Block 5 launch as bad weather threatens delays
SpaceX has fired up twice-flown Falcon 9 booster B1047 ahead of Block 5’s second expendable launch ever, but the company avoided its usual confirmation that a ‘quick look’ data analysis shows the vehicle as ready for launch.
Aside from the unusual phrasing of SpaceX’s static fire confirmation, stating instead that the company “is assessing data”, the weather forecast for the launch of AMOS-17 is looking about as dreary as it was during SpaceX’s most recent July 25th launch, CRS-18. CRS-18 was scrubbed once before the instantaneous launch window luckily coincided with an only partially metaphorical gap in the clouds. However, scheduled to lift off no earlier than 6:52 pm EDT (22:52 UTC), August 3rd, the AMOS-17 commsat launch features a comparatively luxurious ~90-minute window, giving SpaceX a much better shot at ‘threading the needle’.
Still, as indicated in the tweet above, the combination of a horrible weather forecast (70% chance of weather violation on Aug. 3, 60% on Aug. 4), uncertainty surrounding Falcon 9’s static fire test results, and the gravity of this particular launch all suggest that delays are likely.
With most things in rocketry, the adage, “Better late than never!” almost invariably holds true when dealing with late-stage launch vehicle processing, and SpaceX will be taking that to the extreme with this launch for reasons that will become clear. If SpaceX can avoid the growing probability of minor delays, generally an annoying non-issue more than anything else, customer Spacecom will certainly be appreciative, but the most important thing is ensuring the safe orbital delivery of AMOS-17.
Weighing roughly 6500 kg (14,300 lb) fully-fueled, AMOS-17 is a relatively large geostationary communications satellite built by Boeing and, practically speaking, is meant to replace Amos-6, an Israeli-built satellite that was destroyed in September 2016 during a catastrophic Falcon 9 failure. Spacecom effectively took the insurance funds it received from the loss of Amos-6, purchased AMOS-17 via Boeing, and then chose a contract option that gave the company a free Falcon 9 launch instead of taking a cash payout of $50M.
Be it financial necessity or a genuine decision to trust SpaceX that led Spacecom to manifest its replacement satellite on Falcon 9, a second failure and loss of payload (AMOS-17) during this launch would be a spectacular embarrassment and a major wound to SpaceX’s growing reputation as a reliable launch provider. If there is any launch in particular that SpaceX explicitly wants to avoid a failure on, it’s probably AMOS-17.
Perhaps to this end, SpaceX has actually chosen – presumably at the request or suggestion of Spacecom – to expend a Falcon 9 Block 5 booster in support of the AMOS-17 launch. Confirmed by SpaceX to be B1047.2, the company will preclude a landing attempt and instead sacrifice a booster that might otherwise fly a dozen more launches to give Spacecom a larger safety margin and help AMOS-17 start serving customers as quickly as possible. The sooner AMOS-17 can reach its final geostationary orbit (GEO), the sooner Spacecom can begin generating revenue from the satellite.
Finally, SpaceX fairing recovery vessel GO Ms. Tree (formerly Mr. Steven) has just departed Port Canaveral (c. August 1st) and is headed nearly 1000 km (600 mi) east into the Atlantic Ocean for what could be the ship’s second successful fairing catch ever. Stay tuned as SpaceX provides updates and we near AMOS-17’s tentative launch date.

Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
