After traveling more than 3500 miles (5600 km), SpaceX autonomous spaceport drone ship (ASDS) Just Read The Instructions (JRTI) began its eastbound transit of the Panama Canal on August 18th, placing the vessel roughly two-thirds of the way to its unknown destination.

As previously discussed on Teslarati, JRTI’s move came as a bit of a surprise and it’s still anyone’s bet if the SpaceX recovery vessel heads for Texas or Florida immediately after exiting the Panama Canal. Nevertheless, JRTI’s presence at either (or, more likely, both) possible destinations arguably centers around the imminent demands of a planned ramp of SpaceX’s Starlink satellite constellation launch cadence, as well as an equally imminent need for recovery assets to support the first suborbital Starship test flights.

On July 31st, JRTI departed Port of Los Angeles – its home for the last four years – under tow behind tugboat Alice C. The duo arrived at the Canal on August 15th and, after a several-day wait in a large passage queue, the drone ship and its paired tugboat are finally on their way through the canal, although traffic still remains high and another day (or several) of waiting is likely in order.

After successfully making it through the first half of the transit, JRTI and Alice C are currently waiting in line while westbound traffic is routed through. That wait will likely last hours, not days, (hopefully) allowing JRTI to exit the canal on Tuesday or Wednesday, leaving drone ship free to head towards its final destination.

JRTI has two possible destinations: Port of Brownsville, Texas or Port Canaveral, Florida. Both options are roughly 1800 mi (3000 km) from the Panama Canal’s western mouth and, extrapolating from the first major leg of the journey, should take Alice C around 8 days to tow JRTI across the finish line. Barring mishaps, the drone ship should thus be able to arrive at its new home sometime in the final week of August – roughly August 27th to the 31st.

To the East, to the Gulf

As previously discussed on Teslarati, there are good cases to make for both potential drone ship destinations. On the East Coast, SpaceX’s plans to ramp up its internal Starlink launch cadence could require multiple drone ship to prevent those ambitions from seriously impacting the company’s commercial launch manifest. The readiness of one or two of the payloads is uncertain, but SpaceX has anywhere from seven to nine Falcon 9 launches scheduled in Q4 2019, requiring a cadence significantly higher than SpaceX’s activity in the first half of 2019.

At the same time, extrapolating from SpaceX’s H1 2019 cadence (1.33 launches per month), more than doubling that average cadence to 3 launches per month in the final quarter seems ambitious, at a minimum. SpaceX has achieved six-launch quarters several times in the last few years, likely a reasonable expectation for Q4 2019. In short, this is all to say that SpaceX has made do with one drone ship in the past while hitting similar launch cadences, meaning that the need for JRTI at Port Canaveral is probably not urgent.

On the Gulf Coast, SpaceX has established a Starship development facility in Boca Chica, Texas, just a handful of miles north of the southernmost tip of Texas. A full-scale, low-fidelity prototype known as Starhopper completed its first test flight on July 25th and is likely just days away from a second test flight. Meanwhile, SpaceX Boca Chica is simultaneously assembling what CEO Elon Musk has described as the “Mk1” orbital Starship prototype and is making spectacularly rapid progress.

Musk recently tweeted that SpaceX’s Mk1 Starship and a second parallel build – Starship Mk2 – could be ready for their first (suborbital) flights as early as late-September or October, followed by one of the spacecraft’s first orbital launch attempt an incredibly ambitious “2-3 months after” the first test flight. Per additional statements from Musk in 2018 and 2019, SpaceX plans to subject either or both of its Mk1 and Mk1 Starships to a high-altitude, high-velocity test program before proceeding to orbital launch attempts.

Said extreme testing could easily involve Starship traveling on high suborbital trajectories dozens or even hundreds of miles above Earth’s surface, potentially demanding an ocean-going landing platform far downrange. Given that Starship is in its very early stages of integrated development, any downrange assets (i.e. JRTI) needed for test flights will need to be very flexible, as Starship launch attempts could easily slip days or weeks with little to no notice.

Best of both worlds

Although pitting options against each other is entertaining and has its uses, the fact remains that once drone ship JRTI has passed through the Panama Canal, traveling from, say, Florida to Texas or vice versa is far less arduous a journey than the trip from Port of LA. In other words, moving JRTI between Port of Brownsville and Port Canaveral every few months should be very little trouble, easily allowing the drone ship to service both Gulf and East Coast recovery needs.

Given that SpaceX’s next Falcon 9 launch is believed to be no earlier than late-October, it’s not even out of the question that JRTI will stop in Brownsville for one month or several before heading to Port Canaveral as SpaceX attempts to complete a very busy Q4 2019 launch manifest. Stay tuned…

Tesla removes Safety Monitors, begins fully autonomous Robotaxi testing

This development, in terms of the Robotaxi program, is massive. Tesla has been working incredibly hard to expand its fleet of Robotaxi vehicles to accommodate the considerable demand it has experienced for the platform.

Tesla has started Robotaxi testing in Austin, Texas, without any vehicle occupants, the company’s CEO Elon Musk confirmed on Sunday. Two Tesla Model Y Robotaxi units were spotted in Austin traveling on public roads with nobody in the car.

The testing phase begins just a week after Musk confirmed that Tesla would be removing Safety Monitors from its vehicles “within the next three weeks.” Tesla has been working to initiate driverless rides by the end of the year since the Robotaxi fleet was launched back in June.

Two units were spotted, with the first being seen from the side and clearly showing no human beings inside the cabin of the Model Y Robotaxi:

Another unit, which is the same color but was confirmed as a different vehicle, was spotted just a few moments later:

The two units are traveling in the general vicinity of the South Congress and Dawson neighborhoods of downtown Austin. These are located on the southside of the city.

This development, in terms of the Robotaxi program, is massive. Tesla has been working incredibly hard to expand its fleet of Robotaxi vehicles to accommodate the considerable demand it has experienced for the platform.

However, the main focus of the Robotaxi program since its launch in the Summer was to remove Safety Monitors and initiate completely driverless rides. This effort is close to becoming a reality, and the efforts of the company are coming to fruition.

It is a drastic step in the company’s trek for self-driving technology, as it plans to expand it to passenger vehicles in the coming years. Tesla owners have plenty of experience with the Full Self-Driving suite, which is not fully autonomous, but is consistently ranked among the best-performing platforms in the world.

Tesla refines Full Self-Driving, latest update impresses where it last came up short

Tesla released Full Self-Driving v14.2.1.25 on Friday night to Early Access Program (EAP) members. It came as a surprise, as it was paired with the release of the Holiday Update.

We were able to go out and test it pretty extensively on Saturday, and the changes Tesla made from the previous version were incredibly impressive, especially considering it seemed to excel where it last came up short.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version

With Tesla Full Self-Driving v14.2.1, there were some serious regressions. Speed Profiles were overtinkered with, causing some modes to behave in a strange manner. Hurry Mode was the most evident, as it refused to go more than 10 MPH over the speed limit on freeways.

It would routinely hold up traffic at this speed, and flipping it into Mad Max mode was sort of over the top. Hurry is what I use most frequently, and it had become somewhat unusable with v14.2.1.

It seemed as if Speed Profiles should be more associated with both passing and lane-changing frequency. Capping speeds does not help as it can impede the flow of traffic. When FSD travels at the speed of other traffic, it is much more effective and less disruptive.

With v14.2.1.25, there were three noticeable changes that improved its performance significantly: Speed Profile refinements, lane change confidence, and Speed Limit recognition.

Speed Profile Refinement

Speed Profiles have been significantly improved. Hurry Mode is no longer capped at 10 MPH over the speed limit and now travels with the flow of traffic. This is much more comfortable during highway operation, and I was not required to intervene at any point.

With v14.2.1, I was sometimes assisting it with lane changes, and felt it was in the wrong place at the wrong time more frequently than ever before.

However, this was one of the best-performing FSD versions in recent memory, and I really did not have any complaints on the highway. Speed, maneuvering, lane switching, routing, and aggressiveness were all perfect.

Lane Changes

v14.2.1 had a tendency to be a little more timid when changing lanes, which was sort of frustrating at times. When the car decides to change lanes and turn on its signal, it needs to pull the trigger and change lanes.

It also changed lanes at extremely unnecessary times, which was a real frustration.

There were no issues today on v14.2.1.25; lane changes were super confident, executed at the correct time, and in the correct fashion. It made good decisions on when to get into the right lane when proceeding toward its exit.

It was one of the first times in a while that I did not feel as if I needed to nudge it to change lanes. I was very impressed.

Speed Limit Recognition

So, this is a complex issue. With v14.2.1, there were many times when it would see a Speed Limit sign that was not meant for the car (one catered for tractor trailers, for example) or even a route sign, and it would incorrectly adjust the speed. It did this on the highway several times, mistaking a Route 30 sign for a 30 MPH sign, then beginning to decelerate from 55 MPH to 30 MPH on the highway.

This required an intervention. I also had an issue leaving a drive-thru Christmas lights display, where the owners of the private property had a 15 MPH sign posted nearly every 200 yards for about a mile and a half.

The car identified it as a 55 MPH sign and sped up significantly. This caused an intervention, and I had to drive manually.

It seems like FSD v14.2.1.25 is now less reliant on the signage (maybe because it was incorrectly labeling it) and more reliant on map data or the behavior of nearby traffic.

A good example was on the highway today: despite the car reading that Route 30 sign and the Speed Limit sign on the center screen reading 30 MPH, the car did not decelerate. It continued at the same speed, but I’m not sure if that’s because of traffic or map data:

A Lone Complaint

Tesla has said future updates will include parking improvements, and I’m really anxious for them, because parking is not great. I’ve had some real issues with it over the past couple of months.

Today was no different:

Full Self-Driving v14.2.1.25 is really a massive improvement over past versions, and it seems apparent that Tesla took its time with fixing the bugs, especially with highway operation on v14.2.1.

Tesla hints at Starlink integration with recent patent

“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”

Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.

The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”

Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.

These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.

They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:

“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”

One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.

It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).

Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.

Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.

It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.

Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.

SpaceX reaches incredible milestone with Starlink program

Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.
