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.

The Tesla Semi is entering a new Pilot Program with Paper Transport, LLC (PTI), a Wisconsin-based transportation provider. The company will test the Semi’s Long Range configuration through “dedicated operations within the Chicago market.”
Chicago presents an interesting challenge for the Semi, as it will be a colder-weather climate that will test the Semi’s ability to operate in lower temperatures and in potentially large accumulations of snow. This is something Tesla has been testing with the Semi in Alaska and even in Northern California during the colder months, but Chicago will present a truly tough midwestern winter.

PTI says it is using the Semi to evaluate its strategy of reducing transportation emissions while maintaining performance, reliability, and cost efficiency. These are major arguments for the Semi being introduced into new fleets.
CEO of PTI Tyler Ellison said:
“PTI has been a leader in sustainable transportation solutions for over 15 years. We take a consultative approach to helping customers identify and implement the right transportation solution for their network. Our partnership with Tesla expands our portfolio alongside renewable natural gas and intermodal, giving customers more ways to reduce Scope 3 emissions without compromising service or economics.”
PTI is far from the first company to adopt the Semi within a fleet, as Tesla entered strategic agreements with PepsiCo. and its subsidiary Frito-Lay for a Pilot Program that extended throughout the California region.
Tesla has let companies like those utilize the Semi to determine whether it would be suitable for their operations. Additionally, Tesla gets valuable information regarding the Semi’s performance, knowing what to improve and what is ideal for companies that will utilize the all-electric truck for regional and nationwide logistics.
PTI plans to utilize the Long Range configuration, which is priced at $290,000 and features a range of approximately 500 miles, a three-motor powertrain, up to 800 kW of drive power, and consumption of just 1.7 kWh per mile.

VP of Maintenance at PTI, Bryan Ellen, added:
“We are excited to partner with Tesla, leveraging their ever-evolving technology. We are bullish in our estimation of the parallels available between our dedicated model and the efficiency of their fully electric Class 8 tractor. We anticipate a growing synergy between our businesses as we work to facilitate this sustainable solution for our customers.”
PTI has logged more than 87 million miles using sources like compressed and renewable gas, but now is looking to take it a step further with fully electric operations.
Tesla revealed on Monday that it is building a new autonomous vehicle at Gigafactory Texas, its plant just outside of the City of Austin. This particular vehicle will be geared toward those who are in need of a wheelchair-accessible car that would require no human driver for operation.
According to a new report from Wired, Tesla’s Senior Policy Advisor, India Herdman, told members of the Washington D.C. City Council on Monday:
“We are in development for a purpose-built, wheelchair-accessible autonomous vehicle. We know that paratransit can be very difficult, and people who are confined to wheelchairs permanently should still be able to move around freely, so that is an active product being built by Tesla in Texas.”
This builds upon what CEO Elon Musk said last year on X, which confirmed the company was working on accessible rides within its Robotaxi platform, which currently is confined to the Model Y.
Absolutely
— Elon Musk (@elonmusk) September 19, 2025
Tesla is also developing the Cybercab, which started employee rides last week. However, this vehicle is not necessarily geared toward wheelchair accessibility.
That leaves a major gap in the autonomous ride-sharing program that Tesla is attempting to build; the company has been pretty clear that it does not want to complicate its manufacturing lines by bringing in a wide array of body styles.
However, it seems necessary to have something larger that could help transport people to appointments when they cannot drive. For wheelchair accessibility, the Robovan, which was unveiled at the “We, Robot” event in October 2024, seems to be the most ideal solution:
Herdman did not indicate whether she was referring to the Robovan or if Tesla is building yet another body style that is geared toward full autonomy but also caters to the handicapped.
Tesla might need to develop something specifically for the handicapped in order to align with the Americans with Disabilities Act, which prevents discrimination against people with disabilities in transportation services. Uber was hit with a lawsuit late last year for “refusing to reasonably modify its policies, practices, or procedures where necessary to avoid discriminating against riders with disabilities.”
Tesla would obviously like to avoid this.
It will be interesting to see what Tesla will do with this project, and whether it will introduce something new to the market or just continue with the Robovan.
Tesla weirdly confirmed that its steering wheel-less and pedal-less Cybercab vehicle is now in the process of giving employees rides, a huge milestone for the vehicle program.
But the entire thing was super strange. On Friday, Tesla released a video stating that there was “Cool news from Giga Texas” and that employees were now taking rides in Cybercabs that have no manual controls. The units seen on public roads are engineering vehicles that have manual controls inside, a necessity as Tesla moved through the testing phase.
However, Tesla removed the video and reposted it shortly after with a more vague title. It seems like the employee rides are still going, but the video was adjusted slightly. The initial upload showed employees doing things like watching movies and adjusting the climate, but these snippets were removed in the second upload.

Nevertheless, the announcement from Tesla is that the Cybercab is operating with employees inside who can control the vehicle’s audio, video, climate, and destination settings through their smartphone app.
Tesla has already been testing Cybercab engineering units, but last month, it was able to self-certify for SAE Level 4, which would enable unsupervised self-driving in Texas. The company is moving toward that, and the plans have always been to launch Cybercab rides this year.
The Cybercab is potentially looked at as the next generation of Tesla’s mobility leg. For the past 15 years, the company has been known as somewhat of an automaker, among many other things. However, these passenger vehicles that Tesla has manufactured are now moving into a new realm, as they will eventually drive themselves with no supervision thanks to the Full Self-Driving suite.
The Cybercab is just the next step of that: a true vehicle developed for the sole purpose of ride-hailing. It has no human controls, it has only two seats, and it will get passengers from Point A to Point B with no awkward driver, no need for manual inputs, and with no stress.
Tesla is moving forward with other developments related to the Cybercab project as well. However, the big announcement will come when Tesla finally announces that it is launching Cybercab rides to the general public, something that it plans to launch either late this year or early 2027.
