SpaceX Mars rocket test site receives first huge rocket propellant storage tank
SpaceX has delivered one of the first undeniably rocketry-related pieces of hardware to its prospective Boca Chica test and launch facility in South Texas, this time in the form of a massive 100,000-gallon liquid oxygen tank now stationed adjacent to the company’s ~600 kW Tesla solar and battery array.
In a statement provided to local paper Valley Morning Star, SpaceX spokesperson Sean Pitt filled in a few of the details and confirmed that the LOX tank had been delivered to Boca Chica as part of an ongoing effort to ready the site for initial testing – and eventually launches – of an unspecified “vehicle”
“Delivery of a new liquid oxygen tank, which will be used to support propellant-loading operations during launch and vehicle tests, represents the latest major piece of launch hardware to arrive at the [South Texas] site for installation.” – SpaceX
The official SpaceX statement may not have explicitly stated that the aforementioned “vehicle” was something other than Falcon 9 or Heavy, but it can be all but guaranteed that the testing and launching described refers to the company’s next-generation Mars rocket, a completely reusable architecture known as BFR.

A slow burn in South Texas
Over the past 6-9 months, SpaceX CEO Elon Musk and President/COO Gwynne Shotwell have repeatedly spoken on the subject of SpaceX’s South Texas ambitions, lending unambiguous credence to the idea that the Boca Chica rocket facility will be almost exclusively dedicated to testing BFR’s first flightworthy spaceship prototypes, beginning with a series of familiar suborbital “hops”.

In the early days of SpaceX’s Falcon 9 reusability program, the company completed several different phases of short flights (“hops”, hence the Grasshopper label) of a development version of a Falcon 9 booster, ranging from purely vertical jaunts just above the pad to 1000+ meter cross-range maneuvers, tests that ultimately culminated in SpaceX’s extraordinarily reliable Falcon 9 and Heavy booster recovery capabilities. Something similar – albeit somewhat more ambitious – is planned for BFR, starting with a prototype of the upper stage (spaceship). Musk described these plans in more detail in an October 2017 Reddit AMA:
Will we see BFS hops or smaller test vehicles similar to Grasshopper/F9R-Dev?
A (Elon): A lot. Will be starting with a full-scale Ship doing short hops of a few hundred kilometers altitude and lateral distance. Those are fairly easy on the vehicle, as no heat shield is needed, we can have a large amount of reserve propellant and don’t need the high area ratio, deep space Raptor engines.
Speaking a bit less than five months later after the stunningly successful debut of Falcon Heavy, Musk expanded further on the BFR test program, reiterating that spaceship hop testing would “most likely … happen at our Brownsville [South Texas] location,” perhaps as early as 2019.
“We’ll do flights of increasing complexity. We really want to test the heat shield material… like fly out, turn around, accelerate back real hard, and come in hot to test the heat shield.”

Musk also noted that he expected the first full-up orbital launch with both the Booster (BFB) and Spaceship (BFS) could happen as soon as 2021 or 2022. Shotwell, on the other hand, stated in early 2018 and again more recently that she believed BFR could begin its first orbital test missions as early as 2020, an extraordinarily rare moment where the typically pragmatic executive appeared to be more confident than Musk, often lambasted for his reliably over-optimistic timelines. About a month later, Musk’s comments were much more closely aligned with Shotwell’s BFR timeline estimates, and he enthusiastically said that that spaceship hop tests would likely begin within the first half of 2019.
The unambiguous arrival of a rocket propellant storage tank – confirmed officially by SpaceX – strongly suggests that activity is about to seriously pick up speed in Boca Chica for the first time in a year and a half, paving the way for full-scale hop tests of the first Mars spaceship prototype perhaps less than a year from today.

Tesla Cybercab tests are going on overdrive with production-ready units
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the vehicle being reported across social media this week.
Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the autonomous two-seater being reported across social media this week. Based on videos of the vehicle that have been shared online, it appears that Cybercab tests are underway across multiple states.
Recent Cybercab sightings
Reports of Cybercab tests have ramped this week, with a vehicle that looked like a production-ready prototype being spotted at Apple’s Visitor Center in California. The vehicle in this sighting was interesting as it was equipped with a steering wheel. The vehicle also featured some changes to the design of its brake lights.
The Cybercab was also filmed testing at the Fremont factory’s test track, which also seemed to involve a vehicle that looked production-ready. This also seemed to be the case for a Cybercab that was spotted in Austin, Texas, which happened to be undergoing real-world tests. Overall, these sightings suggest that Cybercab testing is fully underway, and the vehicle is really moving towards production.
Production design all but finalized?
Recently, a near-production-ready Cybercab was showcased at Tesla’s Santana Row showroom in San Jose. The vehicle was equipped with frameless windows, dual windshield wipers, powered butterfly door struts, an extended front splitter, an updated lightbar, new wheel covers, and a license plate bracket. Interior updates include redesigned dash/door panels, refined seats with center cupholders, updated carpet, and what appeared to be improved legroom.
There seems to be a pretty good chance that the Cybercab’s design has been all but finalized, at least considering Elon Musk’s comments at the 2025 Annual Shareholder Meeting. During the event, Musk confirmed that the vehicle will enter production around April 2026, and its production targets will be quite ambitious.

Tesla gets a win in Sweden as union withdraws potentially “illegal” blockade
As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Swedish union Vision has withdrawn its sympathy blockade against Tesla’s planned service center and showroom in Kalmar. As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.
Vision’s decision to pull the blockade
Vision announced the blockade in early December, stating that it was targeting the administrative handling of Tesla’s facility permits in Kalmar municipality. The sympathy measure was expected to start Monday, but was formally withdrawn via documents sent to the Mediation Institute and Kalmar Municipality last week.
As noted in a Daggers Arbete report, plans for the strike were ultimately pulled after employer group SKR highlighted potential illegality under the Public Employment Act. Vision stressed its continued backing for the Swedish labor model, though Deputy negotiation manager Oskar Pettersson explained that the Vision union and IF Metall made the decision to cancel the planned strike together.
“We will not continue to challenge the regulations,” Petterson said. “The objection was of a technical nature. We made the assessment together with IF Metall that we were not in a position to challenge the legal assessment of whether we could take this particular action against Tesla. Therefore, we chose to revoke the notice itself.”
The SKR’s warning
Petterson also stated that SKR’s technical objection to the Vision union’s planned anti-Tesla strike framed the protest as an unauthorized act. “It was a legal assessment of the situation. Both for us and for IF Metall, it is important to be clear that we stand for the Swedish model. But we should not continue to challenge the regulations and risk getting judgments that lead nowhere in the application of the regulations,” he said.
Vision ultimately canceled its planned blockade against Tesla on December 9. With Vision’s withdrawal, few obstacles remain for Tesla’s long-planned Kalmar site. A foreign electrical firm completed work this fall, and Tesla’s Careers page currently lists a full-time service manager position based there, signaling an imminent opening.

Tesla Semi program Director teases major improvements
Tesla Semi Program Director Dan Priestly teased the major improvements to the all-electric Class 8 truck on Thursday night, following the company’s decision to overhaul the design earlier this year.
Priestley said he drove the Semi on Thursday, and the improvements appear to be welcomed by one of the minds behind the project. “Our customers are going to love it,” he concluded.

The small detail does not seem like much, but it is coming from someone who has been involved in the development of the truck from A to Z. Priestley has been involved in the Semi program since November 2015 and has slowly worked his way through the ranks, and currently stands as the Director of the program.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
Tesla made some major changes to the Semi design as it announced at the 2025 Annual Shareholder Meeting that it changed the look and design to welcome improvements in efficiency.
Initially, Tesla adopted the blade-like light bar for the Semi, similar to the one that is present on the Model Y Premium and the Cybertruck.
Additionally, there are some slight aesthetic changes to help with efficiency, including a redesigned bumper with improved aero channels, a smaller wraparound windshield, and a smoother roofline for better aero performance.
All of these changes came as the company’s Semi Factory, which is located on Gigafactory Nevada’s property, was finishing up construction in preparation for initial production phases, as Tesla is planning to ramp up manufacturing next year. CEO Elon Musk has said the Semi has attracted “ridiculous demand.”
The Semi has already gathered many large companies that have signed up to buy units, including Frito-Lay and PepsiCo., which have been helping Tesla test the vehicle in a pilot program to test range, efficiency, and other important metrics that will be a major selling point.
Tesla will be the Semi’s first user, though, and the truck will help solve some of the company’s logistics needs in the coming years.
