SpaceX tracks towards first launch of 2019 with flight-proven Falcon 9 static fire

SpaceX has completed a Falcon 9 static fire test ahead of the company’s first launch of 2019, kicking off what is looking to be a truly jam-packed year for Falcon 9 and BFR. Most important, of course, is SpaceX’s primary business and main sources of revenue – safely and reliably launching customer satellites, payloads, and – soon – astronauts into orbit.

Previously tasked with launching heavy communications satellite Telstar 18V in September 2018, Falcon 9 B1049 is now set to launch an arguably historic mission for both SpaceX and customer Iridium, the eighth and final contracted launch of the upgraded Iridium NEXT satellite communications constellation.

Struck all the way back in June 2010, Iridium’s decision to award the full NEXT constellation launch contract to SpaceX less than two weeks after Falcon 9’s first and only launch may well be the greatest calculated leap of faith in the history of commercial spaceflight. SpaceX did admittedly offer an unbeatable price ($492M for eight launches, $61.5M per launch) that may have allowed Iridium to afford a new constellation in the first place, but the risk Iridium took was truly immense at the time.

Originally launched between 1997 and 1998, the first Iridium constellation became and still remains the only satellite communications constellation in history to offer global and persistent coverage anywhere on Earth, allowing those with Iridium devices to guarantee connectivity no matter where they are. To some extent, the original constellation has become a subtle but omnipresent backbone of a huge variety of ventures, companies, and services, ranging from marine vessel tracking and emergency response to the go-to solution for those heading far off the beaten path. As just one small example, SpaceX’s large fleet of sea-going vessels and its cross-country transport infrastructure both rely on Iridium for streamlined company-wide movement tracking, making life considerably easier for logistics and planning teams.

Iridium’s decision to use SpaceX for its NEXT constellation likely also gave SpaceX a massive stature boost, taking it from the company with just a handful of commercial contracts that had failed three of its last five launches to the company that secured what was at the time the largest single commercial launch contract in history. Alongside NASA’s Commercial Orbital Transport Services (COTS) and Resupply Services (CRS) commitments (~14 launches as of 2010), Iridium NEXT raised SpaceX’s commercial manifest from perhaps 2 missions to ~10 while also taking the value of those contracts from an almost negligible sum to well over half a billion dollars.

Although SpaceX and Iridium originally planned for launches to take place over a roughly 24-month period stretch from 2015 to 2017, unplanned technical delays and a duo of catastrophic Falcon 9 failures (CRS-7 and Amos-6) in 2015 and 2016 ultimately pushed Iridium NEXT’s launch debut back several years. Despite those immense hurdles and a range of smaller issues, SpaceX and Iridium were finally able to begin launching satellites in January 2017 and have continued to consistently do so every 3-4 months since then. Aside from one partial NASA rideshare mission that featured five NEXT satellites in May 2018, all seven launches have placed ten NEXT satellites (weighing approx. 10,000 kg or 22,000 lb total) in a variety of low polar orbits without a single known hitch.

Falcon 9 enters the era of reusability

Closely following SES, NASA, and SSL (BulgariaSat), Iridium also became the fourth commercial entity to launch on a flight-proven Falcon 9 rocket for the launch vehicle’s fourth flight-proven mission ever. Iridium-8 will become the fourth constellation launch to fly aboard a sooty Falcon 9 rocket, meaning that a full 50% of the next-gen satellites will have launched on reused rockets, easily one of the coolest bragging rights ever. Currently standing at 65 NEXT satellites in orbit and rapidly nearing operational status, Falcon 9 B1049 and a fresh upper stage will (fingers crossed) place the last ten satellites in orbit to complete the constellation’s last plane and seal the last gap in its perfect global coverage.

Although NEXT would have been valuable for the sole reason that its predecessor satellites are now 5-10 years past their designed lifespans, NEXT will also serve to dramatically increase Iridium’s overall bandwidth, slash concurrent user bottlenecks, and provide a platform for new services like Aireon, which hopes to become the first operator of a truly commercial aircraft tracking service with global satellite-based coverage.

 

All things considered, it will be hugely bittersweet to watch Iridium and SpaceX’s direct relationship come to a close with the launch of Iridium-8. Aside from nine additional on-orbit spares once all 75 are launched, Iridium will also have a complement of six more spares that will be kept in storage on the ground until they are required in orbit. If or when those times come, SpaceX will be able to compete with other launch providers for the opportunity to carry maybe one or two Iridium satellites – likely as rideshare payloads – into orbit sometime in the future.

In the meantime, stay tuned for Iridium-8’s official launch time and date, likely to be announced by SpaceX sometime within the next 24-48 hours.

Tesla has posted job openings for Body Fit Technicians for the Cybercab’s end-of-line assembly, an apparent indication that preparations for the vehicle’s initial production are accelerating at Giga Texas. 

Body Fit Technicians for Cybercab line

As per Tesla’s Careers website, Body Fit Technicians for the Cybercab focus on precision body fitment work, including alignment, gap and flush adjustments, and certification of body assemblies to specification standards. 

Employees selected for the role will collaborate with engineering and quality teams to diagnose and correct fitment and performance issues and handle detailed inspections, among other tasks.

The listing noted that candidates should be experienced with automotive body fit techniques and comfortable with physically demanding tasks such as lifting, bending, walking, and using both hand and power tools. The position is based in Austin, Texas, where Tesla’s main Cybercab production infrastructure is being built.

Cybercab poised for April production

Tesla CEO Elon Musk recently reiterated that the Cybercab is still expected to start initial production this coming April. So far, numerous Cybercab test units have been spotted across the United States, and recent posts from the official Tesla Robotaxi account have revealed that winter tests in Alaska for the autonomous two-seater are underway. 

While April has been confirmed as the date for the Cybercab’s initial production, Elon Musk has also set expectations about the vehicle’s volumes in its initial months. As per the CEO, the Cybercab’s production will follow a typical S-curve, which means that early production rates for the vehicle will be very limited. 

“Initial production is always very slow and follows an S-curve. The speed of production ramp is inversely proportionate to how many new parts and steps there are. For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast,” Musk wrote in a post on X.

Swedish labor unions are considering whether to file a police report related to a newly opened Tesla Megapack Supercharger near Stockholm, citing questions about how electricity is supplied to the site. The matter has also been referred to Sweden’s energy regulator.

Tesla Megapack Supercharger

The Tesla Megapack Supercharger opened shortly before Christmas in Arlandastad, outside Stockholm. Unlike traditional charging stations, the site is powered by an on-site Megapack battery rather than a direct grid connection. Typical grid connections for Tesla charging sites in Sweden have seen challenges for nearly two years due to union blockades.

Swedish labor union IF Metall has submitted a report to the Energy Market Inspectorate, asking the authority to assess whether electricity supplied to the battery system meets regulatory requirements, as noted in a report from Dagens Arbete (DA). The Tesla Megapack on the site is charged using electricity supplied by a local company, though the specific provider has not been publicly identified.

Peter Lydell, an ombudsman at IF Metall, issued a comment about the Tesla Megapack Supercharger. “The legislation states that only companies that engage in electricity trading may supply electricity to other parties. You may not supply electricity without a permit, then you are engaging in illegal electricity trading. That is why we have reported this… This is about a company that helps Tesla circumvent the conflict measures that exist. It is clear that it is troublesome and it can also have consequences,” Lydell said.

Police report under consideration

The Swedish Electricians’ Association has also examined the Tesla Megapack Supercharger and documented its power setup. As per materials submitted to the Energy Market Inspectorate, electrical cables were reportedly routed from a property located approximately 500 meters from the charging site.

Tomas Jansson, ombudsman and deputy head of negotiations at the Swedish Electricians’ Association, stated that the union was assessing whether to file a police report related to the Tesla Megapack Supercharger. He also confirmed that the electricians’ union was coordinating with IF Metall about the matter. “We have a close collaboration with IF Metall, and we are currently investigating this. We support IF Metall in their fight for fair conditions at Tesla,” Jansson said.

Tesla’s Hardware 4.5 computer appears to have surfaced in newly delivered Model Y vehicles, prompting fresh speculation about an interim upgrade ahead of the company’s upcoming AI5 chip.

Owners taking delivery of recent Model Y builds have identified components labeled “AP45,” suggesting Tesla may have quietly started rolling out revised autonomy hardware.

Hardware 4.5 appears in new Model Y units

The potential Hardware 4.5 sighting was first reported by Model Y owner @Eric5un, who shared details of a Fremont-built 2026 Model Y AWD Premium delivered this January. As per the Model Y owner, the vehicle includes a new front camera housing and a 16-inch center display, along with an Autopilot computer labeled “AP45” and part number 2261336-02-A.

The Tesla owner later explained that he confirmed the part number by briefly pulling down the upper carpet liner below the Model Y’s glovebox. Other owners soon reported similar findings. One Model Y Performance owner noted that their December build also appeared to include Hardware 4.5, while another owner of an Austin-built Model Y Performance reported spotting the same “AP45” hardware.

These sightings suggest that Tesla may already be installing revised FSD computers in its new Model Y batches, despite the company not yet making any formal announcements about Hardware 4.5.

What Hardware 4.5 could represent

Clues about Hardware 4.5 have surfaced previously in Tesla’s Electronic Parts Catalog. As reported by NotATeslaApp, the catalog has listed a component described as “CAR COMPUTER – LEFT HAND DRIVE – PROVISIONED – HARDWARE 4.5.” The component, which features the part number 2261336-S2-A, is priced at $2,300.00.

Longtime Tesla hacker @greentheonly has noted that Tesla software has contained references to a possible three-SoC architecture for some time. Previous generations of Tesla’s FSD computer, including Hardware 3 and Hardware 4, use a dual-SoC design for redundancy. A three-SoC layout could allow for higher inference throughput and improved fault tolerance.

Such an architecture could also serve as a bridge to AI5, Tesla’s next-generation autonomy chip expected to enter production later in 2026. As Tesla’s neural networks grow larger and more computationally demanding, Hardware 4.5 may provide additional headroom for vehicles built before AI5 becomes widely available.
