SpaceX fires up Falcon 9 rocket for fifth Starlink launch in four weeks
SpaceX has static-fired a flight-proven Falcon 9 booster for what will be the company’s fifth Starlink launch in four weeks.
Set to be the company’s 28th operational launch of Starlink v1.0 satellites and 30th Starlink launch overall, the mission – known as Starlink L28 or Starlink-28 – is scheduled to launch no earlier than (NET) 2:59 pm EDT (18:59 UTC) on Wednesday, May 26th, less than 11 days after Starlink-26. The mission will be SpaceX’s fifth Starlink launch in 29 days and sixth launch in less than five weeks – not including Starship SN15’s successful suborbital launch and landing on May 5th.
As previously discussed on Teslarati, Starlink-28’s successful launch would leave SpaceX just two flights away from a truly remarkable feat of sustained launch cadence.
“If the weather, space station, and SpaceX’s rockets, spacecraft, and pad facilities cooperate, the completion of those three upcoming missions would mark eight successful Falcon 9 launches – carrying two Dragon spacecraft, four astronauts, and almost 300 satellites to orbit – in less than six weeks (41 days). If SpaceX manages that feat and averages one launch every five days, the company will have completed ~45% of its 2021 launches in ~26% of the year to date – a clear pattern of acceleration.”

Starlink-28 is set to reuse Falcon 9 B1063 after the booster debuted on SpaceX’s West Coast Vandenberg Air Force Base (VAFB) launch site. Some degree of processing was completed at the pad’s facilities before the once-flown rocket was shipped from California to Florida in March 2021. When B1063 arrived, it appeared to be missing several of its Merlin 1D engines, which helps to explain why SpaceX chose to perform an increasingly rare static fire test with a flight-proven booster.
The unusual six-month gap between B1063’s first and second flights can likely be explained by the fact that the booster was at one point expected to stay in California to launch another mission for NASA as early as July 2021. In February 2021, NASA announced that the Double Asteroid Redirect Test – DART – mission’s launch had been delayed by spacecraft issues to a secondary window beginning in late November, which is likely why B1063 headed to Florida a few weeks later.
According to comments made by SpaceX President and COO Gwynne Shotwell just last month, Starlink-28’s successful completion could leave the company with enough satellites for “full [global] connectivity.” Around a third of those Starlink satellites will still need to boost themselves into operational orbits before that (mostly) uninterrupted global coverage can be realized, but it will just be a matter of time once the spacecraft are already in orbit. True global coverage will require a number of dedicated polar launches, but those West Coast Starlink missions could begin as soon as this summer.
Following Starlink-28, SpaceX has two more launches scheduled within eight days of the mission – an SXM-8 radio satellite mission on June 1st and Cargo Dragon 2’s second space station resupply run on June 3rd. Beyond those three launches, SpaceX has at least two or three more missions nominally scheduled in June.
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.
