NASA has formally given SpaceX permission for Crew Dragon’s second launch – a crucial test flight that should be the last before SpaceX launches NASA astronauts to the International Space Station (ISS) for the first time ever.

Known as its In-Flight Abort (IFA) test, Crew Dragon will attempt to escape a Falcon 9 rocket while airborne, a feat that CEO Elon Musk says will almost certainly destroy the rocket in the process. Technically speaking, NASA and SpaceX completed what is known as a Launch Readiness Review (LRR) sometime on Thursday, allowing SpaceX to proceed with launch preparations. By all accounts, Crew Dragon’s IFA test will likely be one of the most spectacular SpaceX launches ever, given that it is all but guaranteed to result in the intentional in-flight failure of a massive Falcon 9 rocket – “destroyed in Dragon fire” according to Musk.

Thanks to a much smoother launch flow compared to Crew Dragon’s Demo-1 orbital launch debut on Falcon 9, SpaceX’s newest Crew Dragon capsule is scheduled to lift off from Kennedy Space Center Launch Complex 39A (KSC LC-39A) as early as 8 am EST (13:00 UTC), Saturday, January 18th. The In-Flight Abort test will likely be one of Crew Dragon’s most challenging hurdles yet but success would be a major boon for the spacecraft’s demonstrated safety. While both Boeing and SpaceX will ultimately ferry NASA astronauts to and from the ISS, only SpaceX chose to prove Crew Dragon’s in-flight abort capabilities in the real world.

Effectively condemned to destruction to support a greater cause after a productive life, Falcon 9 Block 5 booster B1046 rolled out to Pad 39A – Crew Dragon mounted atop it – on January 16th after successfully performing its last routine static fire on the 11th. As previously discussed on Teslarati, B1046 is the first Falcon 9 Block 5 booster completed by SpaceX and is thus also the oldest flightworthy rocket in the company’s substantial fleet.

“After becoming the first SpaceX booster to launch three times in December 2018, B1046 spent several months at SpaceX’s Hawthorne, CA factory undergoing inspections and refurbishment. At some point, SpaceX assigned the thrice-flown booster to support Crew Dragon’s In-Flight Abort (IFA) test – effectively a death sentence – and shipped the booster to Florida, where it publicly appeared for the first time in months on October 3rd, 2019. Given that four more Falcon 9 boosters have now successfully performed three (or even four) orbital-class launches each, B1046’s now-imminent demise is certainly disappointing but remains extremely pragmatic.”

As such, there is arguably no better booster for SpaceX to expend even if its loss is still less satisfying than a successful post-launch landing. In fact, aside from NASA’s prematurely-retired Space Shuttle, the entire history of orbital-class rocketry has effectively operated on the assumption that it’s both normal and necessary for rockets to be almost entirely expendable.

Only by sheer force of will has SpaceX turned that assumption on its head, making the act of expending Falcon 9 or Falcon Heavy boosters feel suddenly morose. Even then, the practice of propulsively landing orbital-class boosters is scarcely four years old, while reusing those boosters has been ongoing for less than three years. As such, B1046’s demise should be enjoyed for what it ultimately is: the spectacular retirement of a rocket that has already helped launch three separate payloads to orbit.

Perhaps even more importantly, B1046’s sacrifice should – if things go as planned – also pave the way for Crew Dragon to launch its first NASA astronauts into orbit just a few months from now. For the test to be successful, however, Crew Dragon will have to perform an extremely precise string of maneuvers – the failure of any one of which could potentially lead to the spacecraft’s destruction.

“Traveling as fast as Mach 2.5 (860 m/s) at an altitude of 28 kilometers (17 mi), Crew Dragon will ignite its abort thrusters and attempt to escape, the very act of which will likely hammer the spacecraft’s windward surfaces with an extra dozen or so metric tons (~25,000 lb) of aerodynamic pressure. Crew Dragon C205 could thus find itself traveling almost Mach 3 (more than a kilometer per second) moments after separating from Falcon 9, eventually reaching an apogee of almost 75 km (45 mi), after which it will reenter the bulk of Earth’s atmosphere and have to deploy an array of parachutes to ensure a gentle Atlantic Ocean splashdown.”

On November 13th, SpaceX successfully static fired Crew Dragon’s SuperDraco abort thrusters. Two months later, the spacecraft is set for its critical In-Flight Abort (IFA) test. (SpaceX)

Unfortunately, Crew Dragon escaping a supersonic Falcon 9 also means that that same Falcon 9 – basically a thin, flexible tube designed to be as light as possible – will meet a supersonic blast of air the moment Dragon’s SuperDraco abort thrusters ignite. A bit like if a hurricane on all kinds of meteorological steroids just sort of punched a soda can for fun, that airstream will almost certainly obliterate Falcon 9’s sacrificial upper stage into a sort of aluminum snow, quickly revealing – and likely then destroying – B1046’s carbon fiber interstage.

The rest of the thrice-flown Falcon 9 booster is also liable to break up after that supersonic punch. In fact, SpaceX engineers are so confident in B1046’s imminent demise that the booster will have neither landing legs or grid fins come launch. In a best-case scenario, if, against all odds, B1046 survives Dragon’s escape, the intact booster will subsequently impact the Atlantic Ocean at terminal velocity and become a nice, artificial reef off the coast of Florida. Stay tuned for updates from Teslarati and photographers Jamie Groh and Richard Angle as Falcon 9 B1046’s demise inches ever closer.

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

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 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.

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

It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.

Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.

Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.

For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.

It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.

Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.

As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.

This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:

  • Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
  • Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
  • Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
  • Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
  • Santa Mode – New graphics, trees, and a lock chime
  • Light Show Update – Addition of Jingle Rush light show
  • Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
  • Navigation Improvements – Easier layout and setup
  • Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
  • Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
  • Phone Left Behind Chime – Your car will now tell you if you left a phone inside
  • Charge Limit Per Location – Set a charge limit for each location
  • ISS Docking Simulator –  New game
  • Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition

Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.
