SpaceX could begin testing its Mars rocket in Texas by late 2018, early 2019
On the heels of a successful wet dress rehearsal for Falcon Heavy, SpaceX’s President and COO Gwynne Shotwell spoke briefly about SpaceX for an aerospace conference located at Texas’ Academy of Medicine, Engineering & Science. Ars Technica’s senior spaceflight editor Eric Berger was in attendance and provided a rough outline of live tweets during the first group of presentations.
While the phrasing cannot provide absolute confirmation, Berger summarized a statement by Shotwell suggesting that SpaceX’s Boca Chica, Texas launch site, currently in the early stages of construction, could be ready to host “vehicle tests” as soon as late 2018, early 2019. At this point in time, based on comments from Shotwell and CEO Elon Musk, it can be reasonably assumed that SpaceX’s Texas launch facilities will be dedicated mainly to the company’s interplanetary colonization efforts, and will probably be tailored to support the testing and eventual launches of BFR/BFS.
Some news from Shotwell: Brownsville launch site ready for vehicle tests in late 2018, early 2019. Move to launch site after that.

After nine months of earnest construction and rehabilitation, SpaceX’s LC-40 pad was recently reactivated and has since supported two launches without any major hitches. At the same time, LC-39A in flux in order to support launches of SpaceX’s new Falcon Heavy rocket, the size of which required some concomitant upgrades to multiple ground systems. With both of those major tasks now effectively complete, SpaceX’s pad construction team is free to either refocus their efforts towards Boca Chica. Over the past several months, Boca Chica has seen a gradual but consistent level of development, mainly by way of unaffiliated SpaceX contractors. These changes have been dutifully tracked over the last several years on NASASpaceflight.com forums by a handful of friendly local residents interested in the changes coming to Boca Chica and Brownsville, Texas, a nearby town.

Most significantly, the last several months have seen three major developments. First and most prominently, a permanent facility called STARGATE externally appears complete and its two large radio communication dishes have been installed nearby. The STARGATE facility is a public-private partnership between the University of Texas at Brownsville (now part of University of Texas Rio Grande Valley) and SpaceX, with the academic components focusing on research that SpaceX undoubtedly has interest in: improved orbital spacecraft tracking and communications. Operationally, SpaceX will use the facilities to communicate with and operate its Crew Dragon spacecraft during launches, set to begin with an uncrewed demonstration mission as early as August 2018.
Second, an absolutely massive trolley crane appeared on SpaceX’s land and was eventually housed in an apparently purpose-built shed. The crane dwarfs anything currently used at SpaceX’s launch facilities and is almost certainly a custom-ordered piece of equipment, and thus would be both expensive and explicitly purposeful. What that purpose might be is currently unknown, but it is entirely plausible that the crane is intended to support initial testing (or even limited manufacturing) of SpaceX’s first BFS prototype rockets. This speculation has now been strengthened by Shotwell’s January 11 2018 comment on potential “vehicle tests” occurring at the site within a year or so, and also meshes with a presentation she gave in October 2017 at MIT. It also fits with Elon Musk’s 2017 IAC comments that BFR construction tooling and facilities were respectively already ordered and under construction.

Third and last, the aforementioned SpaceX-following locals observed the early stages of a solar power install beginning on some of SpaceX’s Boca Chica land in late 2017, and also noted that at least some of its contractors were part of Tesla Solar. Plans and permits for solar power were acknowledged as far back as 2014, although at that point the contractor was Solar City (now a part of Tesla). A handful of months later, NASASpaceflight user and all-around awesome guy Nomadd has installed a webcam on a tall pole with a wonderful view of both the solar installation (now nearly completed) and STARGATE. The acre of solar panels can be expected to produce as much as half a megawatt (MW) at peak sun, likely more than enough to offset a considerable amount of the facilities’ electricity usage even after it begins to be see serious use.

Originally announced as an additional Falcon launch facility in 2014, Boca Chica has remained relatively dormant over the last three years, and it is truly exciting to see activity ramping up. There are admittedly significant barriers that will prevent SpaceX from effortlessly repurposing its Boca Chica pad for BFR, a much larger rocket. If SpaceX intends to do that, they will almost certainly need to pass a significantly updated FAA environmental impact review and account for any remediations that might be required. Still, that is a small ask for for Brownsville’s local government and Texas as a whole, both of which have clearly enjoyed and begun to benefit from SpaceX’s presence in the otherwise unknown area. SpaceX is unlikely to give up on Boca Chica in the near term, so long as Ms. Shotwell maintains her belief that it is effectively the perfect location for BFR launches.
Overall, Shotwell’s comments over the last several months and today in particular are increasingly encouraging, and things are likely to only speed up as 2018 progresses, allowing SpaceX to focus more and more of its expertise on BFR, BFS, and its South Texas testing and launch facilities.
Full disclosure: As Shotwell did not specify which vehicle or vehicles could be expected to begin testing in 2018/2019, it is possible that Falcon 9, not BFR, was the statement’s target. This article should be taken with a grain of salt, as it is educated speculation based upon public information from SpaceX executives and Texas contractors. Teslarati reached out to SpaceX for additional information, but the company was unable to comment further on Shotwell’s presentation at the moment.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.

However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
