SpaceX, NASA hold press conference, historic astronaut launch clears final hurdles before readiness
With less than a month to go before the historic first crewed flight – and final human rating certification test – of the SpaceX Crew Dragon Demonstration 2 mission, NASA and SpaceX jointly held a full day of pre-mission press conferences on Friday, May 1st. Throughout the day many minor, but crucial, details were revealed.
Two primary technical concerns remained prior to Crew Dragon’s debut astronaut mission- the final drop test of the Crew Dragon Mark III parachutes and NASA’s clearance of SpaceX’s resolution of an in-flight engine-out anomaly suffered during the ascent phase of a previous Starlink mission.
Falcon 9 Merlin 1D engine-out anomaly
During the March 18th Starlink launch of a four-time flown Falcon 9 first-stage booster, a brief anomalous engine flare was witnessed during the ascent. Although ultimately successful in the deployment of the stack of 60 satellites, the first-stage booster failed to stick the landing aboard the autonomous spaceport drone ship “Of Course I Still Love You” resulting in a total loss. SpaceX CEO, Elon Musk, responded to comments posted to Twitter confirming the in-flight, early shutdown anomaly of one of the nine Merlin 1D engines.
Musk provided assurance that a thorough investigation would be conducted by SpaceX prior to any return to flight. Musk also noted that the first-ever engine failure of a Merlin 1D engine proved its robustness and the importance of redundancy provided by the other eight engines.
Just prior to the next Starlink mission on April 22nd marking a recycled Falcon 9 booster’s return to flight, Musk once again took to Twitter to provide insight into the early shutdown, in-flight anomaly. Musk stated that a small amount of isopropyl alcohol, used for cleaning the Merlin 1D engines, had been trapped in a sensor dead leg – later clarified as “an area it couldn’t float through” by SpaceX webcast host Lauren Lyons – and was ignited during flight causing the early shutdown of one Merlin 1D engine.
As identified during the April 22nd launch broadcast, out of an abundance of caution SpaceX decided to forgo that cleaning process for the April 22nd mission. However, no information was divulged regarding NASA’s response to either the anomaly or the resolution. Ultimately, the first stage Falcon 9 booster of the Starlink-6 performed flawlessly and even managed to stick the landing aboard the awaiting drone ship.
During Friday’s Commercial Crew and International Space Station overview news conference, a question regarding NASA’s response to the anomaly posed by Jeff Foust – reporter for SpaceNews.com – was directed to NASA’s Commercial Crew Program program manager, Kathy Lueders. She was asked to expand on the final technical constraints remaining prior to the launch of the Crew Dragon DM-2. Lueders responded positively stating that NASA had “reviewed the anomaly resolution…and cleared the engines on our launch vehicle” referring to the Falcon 9 booster slated to support DM-2, noting that the engine-out issue had been satisfactorily resolved and is now behind them.
One more drop test
Early in Friday’s Commercial Crew and International Space Station overview news conference – and later confirmed during remarks made by Lueders – SpaceX Chief Operating Officer, Gwynne Shotwell noted that a final 27th drop test of the Crew Dragon Mk III parachutes was scheduled to be completed later in the day. During a later Q&A interview with the crew of DM-2 – NASA astronauts Bob Behnken and Doug Hurley – Hurley commented that the final drop test had begun, however, he wasn’t quite sure if it had been completed successfully or not.
Just after the closing remarks of the crew Q&A interview, SpaceX announced via social media the successful completion of the 27th and final drop test of the all-important Mk III parachutes.
The May 1st final parachute drop test followed a worrisome stumble of the parachute program on March 24th. SpaceX announced that a Crew Dragon test article had become unstable forcing the helicopter pilot to prematurely release the test article out of an abundance of caution to maintain the safety of the helicopter crew. SpaceX noted that “while the test article was lost, this was not a failure of the parachute system and most importantly no one was injured.”
The confirmation of the successful May 1st drop test and the resolution of the Merlin 1D engine anomaly close out one of the final chapters of prerequisites prior to returning human spaceflight to American soil.
The only hurdles that remain to be cleared are various agency-level readiness reviews. According to Lueders, a SpaceX Flight Readiness Review is tentatively scheduled for Friday, May 8th followed by a NASA Flight Readiness Review on May 11th. Just one week ahead of launch, the final joint Launch Readiness Review is tentatively scheduled to be completed Wednesday, May 20th at which point DM-2 will bring crewed astronaut spaceflight back to American soil for the first time in nearly a decade.

Tesla starts Robotaxi testing without any vehicle occupants
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:

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.
Testing is underway with no occupants in the car

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
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.
🚨 Many of you asked us to test highway driving with Tesla Full Self-Driving v14.2.1.25. Here’s what we noticed:

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:
🚨 We listened to and read a lot of you who had a complaint of Tesla Full Self-Driving v14.2.1 incorrectly reading Speed Limit signs
This appears to be resolved in v14.2.1.25.

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:
🚨 My lone complaint with my drive on Tesla FSD v14.2.1.25 was this strange parking instance.
FSD swung out wide to the left to pull into this spot and this is where it seemed to be stumped. I gave it about 10 seconds after the car just stopped moving for it to make some… https://t.co/ZEkhTHOihG pic.twitter.com/TRemXu5DLf

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.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

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.
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.
