SpaceX’s most important Falcon 9 booster yet returns to port with a lean

Published

On November 19th, what is likely SpaceX’s most important Falcon 9 booster yet returned to Port Canaveral with a surprise – perhaps the most dramatic lean ever observed on one of the recovered rockets.

Tilted a solid 10+ degrees from vertical, the lean was immediately visible as soon as the top of the rocket crest the horizon, and it later became clear that one of Falcon 9 booster B1061’s four landing legs had no contact at all with drone ship Just Read The Instruction’s (JRTI) deck. Four days prior, Falcon 9 (and B1061) became the first commercially-developed rocket in history to be certified to launch NASA astronauts, a feat it pulled off flawlessly. Crew Dragon safely delivered four astronauts to the International Space Station on November 16th, marking the culmination of more than half a decade of (mostly) uninterrupted work.

Even before Crew Dragon and Falcon 9’s momentous Crew-1 launch, though, NASA had already revealed some details that would make parts of Crew-1 even more important and the follow-up Crew-2 launch – scheduled as early as March 2021 – perhaps the most significant mission in SpaceX’s history.

In short, less than a month after SpaceX’s equally flawless Crew Dragon Demo-2 astronaut launch debut, NASA contract modifications revealed that the agency had permitted SpaceX to reuse both Dragon capsules and Falcon 9 boosters on upcoming astronaut launches.

“In a wholly unexpected turn of events, a modification to SpaceX’s ~$3.1 billion NASA Commercial Crew Program (CCP) contract was spotted on June 3rd. Without leaving much room for interpretation, the contract tweak states that SpaceX is now “[allowed to reuse] the Falcon 9 launch vehicle and Crew Dragon spacecraft beginning with” its second operational astronaut launch, known as Post Certification Mission-2 (PCM-2) or Crew-2.”

A few short months after that discovery, NASA itself specifically announced that it had given SpaceX the go-ahead to reuse Demo-2 Crew Dragon capsule C206 and Crew-1 Falcon 9 booster B1061 on Crew-2, the company’s second operational astronaut launch. Scheduled no earlier than March 31st, 2021, Crew-2 will most likely launch before the Crew-1 Crew Dragon departs the space station and returns its four crew members to Earth, a milestone expected sometime in April.

For almost anyone who has followed NASA’s Commercial Crew Program (CCP) and its attitude towards SpaceX’s reusability efforts from the beginning, the space agency’s rapid willingness to trust its most important cargo – humans – to flight-proven Dragons and Falcon 9 boosters came as a huge surprise. If SpaceX is able to reuse both capsule C206 and booster B1061 as planned, Crew-2 will without a doubt be the most significant milestone in commercial spaceflight history, simultaneously proving that astronauts can be safely launched on commercial flight-proven rockets and spacecraft.

Of course, while Demo-2 Crew Dragon capsule C206 may have already been successfully recovered, SpaceX still had to land Falcon 9 booster B1061 and safely return it to port after Crew-1 before it could consider reusing it on Crew-2. Based on the rocket’s appearance upon its arrival at Port Canaveral, B1061 had an extremely close call. With what can be intuited from observation alone, it appears that sometime after B1061 landed and before the drone ship’s tank-like ‘Octagrabber’ robot could secure the booster, a stray swell or sudden burst of high seas must have bucked Just Read The Instructions about, causing B1061 to slide around on the slippery deck.

That would explain why the Falcon 9 first stage arrived in port on one of the far corners of drone ship JRTI – also sign that B1061 likely hit the yellow barrier included specifically to prevent boosters from sliding off drone ship decks. At the same time, B1061 must have had a moderately rough landing, causing at least one of its four legs to expend a large portion of a single-use shock absorber called a “crush core,” leaving the booster sitting at an angle. Based on photos of the arrival, that tilt likely left JRTI’s Octagrabber unable to latch onto all four of Falcon 9’s hold-down clamps, forcing recovery technicians to improvise and manually chain the rocket to the deck where the robotic solution fell short.

Despite the lean, B1061 was lifted onto land for leg retraction without issue around 24 hours after arriving in port. (Richard Angle)

Thankfully, the SpaceX recovery team’s apparent heroics and luck proved to be enough and the sturdy Falcon 9 booster was returned to dry land without issue, lifted off of JRTI’s deck around 24 hours after arriving in port. Based on photos of the crush cores at the bottom tip of each leg, B1061’s rough landing and eventful journey was fairly mild as far as they come and, as CEO Elon Musk notes, crush core replacement is likely all that’s needed to make the rocket good as new.

Had B1061 been lost at sea, Crew-2 would have almost certainly been delayed to give SpaceX enough time to come up with an entirely new Falcon 9 first stage. Luckily for SpaceX, that didn’t happen and the company’s plans to launch astronauts on the flight-proven booster are still in play.

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.
