SpaceX Falcon 9 rocket aces eighth launch and “envelope expansion” landing
SpaceX has successfully completed the first of dozens of Starlink launches planned in 2021, simultaneously crushing multiple rocket reusability records and completing an “envelope expansion” booster landing at sea.
Ending several days of delays, Falcon 9 booster B1051, an expendable upper stage, a flight-proven payload fairing, and 60 new Starlink satellites lifted off at 8:02 am EST, kicking off SpaceX’s 16th operational Starlink mission and 17th Starlink launch overall. Roughly an hour later, after spinning up end over end, Falcon 9’s orbital second stage successfully released all 60 satellites to complete an exceptionally milestone-rich mission.
Starlink-16 is such a significant mission for several different reasons.
First and foremost, as previously discussed on Teslarati, Falcon 9 B1051 simultaneously crushed the world-record for rocket turnaround and became the first booster to successfully launch and land eight times, making it SpaceX’s “life-leader” in multiple ways.
“Last flown for the seventh time on December 13th, Falcon 9 B1051 is now scheduled to attempt its eighth orbital-class launch and landing just 36 days later, beating the 51-day world record by almost a third (~30%) and simultaneously becoming the first Falcon booster to launch eight times. If successful, SpaceX’s Falcon rockets will be mere days away from demonstrating monthly reusability.”

Delayed from January 17th to the 20th, that schedule didn’t hold exactly but B1051 did still become the first reusable rocket to drop below the 40-day turnaround mark, completing two launches and landings in 38 days, crushing the previous world record of 51 days (also held by Falcon 9) by almost two weeks.
Those milestones alone are major achievements for SpaceX’s workhorse rocket, leaving the Falcon Block 5 design upgrade just two flights away from achieving its 10-flight design goal and seven or eight days away from monthly reusability. The fact alone that SpaceX’s turnaround timing appears to be accelerating for fleet-leader (most flown) boosters serves as a clear sign that the design has almost certainly achieved that 10-flight goal and is likely capable of far more flights still. If that trend continues, Falcon 9 B1051 could complete its ninth and tenth flights as early as March and April.
Additionally, while a 38-day turnaround is significantly more than a magnitude away from CEO Elon Musk’s long-held goal of 24-hour reusability, it does represent an order-of-magnitude improvement from SpaceX’s first booster reuses, which averaged 200-500+ days between flights.
According to SpaceX, Starlink-16 and booster B1051’s last milestone was successfully expanding Falcon 9’s operational envelope by landing in exceptionally high ground winds. Completed with no apparent issues, that success means that SpaceX will be able to expand the range of conditions Falcon 9 can launch and land in, improving the odds of favorable weather in the future.

Elon Musk reveals date of Tesla Full Self-Driving’s next massive release
Initially planned for a January or February release, v14.3 aims to add some reasoning and logic to the decisions that Full Self-Driving makes, which could improve a lot of things, including Navigation, which is a major complaint of many owners currently.
Tesla CEO Elon Musk revealed the date of Full Self-Driving’s next massive release: v14.3.
For months, Tesla owners with Hardware 4 have been utilizing Full Self-Driving v14.2 and subsequent releases. Currently, the most up-to-date FSD version is v14.2.2.5, which has definitely brought out mixed reviews. With releases, some things get better, and other things might regress slightly.
For the most part, things are better in terms of overall behavior.
However, many owners have been looking forward to the next release, which is v14.3, about which Musk has said many great things. Back in November, Musk said that v14.3 “is where the last big piece of the puzzle lands.”
He added:
“We’re gonna add a lot of reasoning and RL (reinforcement learning). To get to serious scale, Tesla will probably need to build a giant chip fab. To have a few hundred gigawatts of AI chips per year, I don’t see that capability coming online fast enough, so we will probably have to build a fab.”

Tesla Full Self-Driving v14.2 is a considerable improvement from early versions of the suite, but we have written about the somewhat confusing updates that have come with recent versions.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
They’ve been incredibly difficult to gauge in terms of progress because some things have gotten better, but there seems to be some real regression on a handful of things, especially with confidence and assertiveness.
Musk confirmed today on X that Tesla is already testing v14.3 internally right now. It will hit a wide release “in a few weeks,” so we should probably expect it by late April.
It’s in testing right now. Wide release in a few weeks.

Overall, there are high hopes that v14.3 could be a true game changer for Tesla Full Self-Driving, as many believe it could be the version that Robotaxis in Austin, Texas, some of which are driverless and unsupervised, are running.
It could also include some major additions, including “Banish,” also referred to as “Reverse Summon,” which would go find a parking spot after dropping occupants off at their destination.
What Tesla will roll out, and when exactly it arrives, all remain to be seen, but fans have been ready for a new version as v14.2.2.5 has definitely run its course. We have had a lot of readers tell us their biggest request is to fix Navigation errors, which seem to be one of the most universal complaints among daily FSD users.

Chattanooga Charge: Tesla and EV fans ready for the Southeast’s wildest Tesla party
From Cybertruck Convoys to Kid-Friendly Fun Zones: The Chattanooga Charge Has Something for Everyone
Hundreds of like-minded Tesla and EV enthusiasts are descending on Chattanooga Charge this weekend for the largest Tesla meet in the Southeast. Taking place on March 20–22, 2026 at the stunning Tennessee Riverpark.
If you were there last year, you’ll know that it’s the ultimate experience to see the wildest Teslas in action, see the best in EV tech, and arguably the most fun – finally put a name to the face and connect with those social media buddies IRL! Oh, and that epic night time Tesla light show is a once-in-a-lifetime experience that will transform the Riverpark into something out of a sci-fi film that’s remarkably unforgettable and must be seen in person.

Tesla Full Self-Driving gets latest bit of scrutiny from NHTSA
The analysis impacts roughly 3.2 million vehicles across the company’s entire lineup, and aims to identify how the suite’s degradation detection systems work and how effective they are when the cars encounter difficult visibility conditions.
The National Highway Traffic Safety Administration (NHTSA) has elevated its probe into Tesla’s Full Self-Driving (Supervised) suite to an Engineering Analysis.
The analysis impacts roughly 3.2 million vehicles across the company’s entire lineup, and aims to identify how the suite’s degradation detection systems work and how effective they are when the cars encounter difficult visibility conditions.
The step up into an Engineering Analysis is often required before the NHTSA will tell an automaker to issue a recall. However, this is not a guarantee that a recall will be issued.

The NTHSA wants to examine Tesla FSD’s ability to assess road conditions that have reduced visibility, as well as detect degradation to alert the driver with sufficient time to respond.
The Office of Defects Investigation (ODI) will evaluate the performance of FSD in degraded roadway conditions and the updates or modifications Tesla makes to the degradation detection system, including the timing, purpose, and capabilities of the updates.
Tesla routinely ships software updates to improve the capabilities of the FSD suite, so it will be interesting to see if various versions of FSD are tested. Interestingly, you can find many examples from real-world users of FSD handling snow-covered roads, heavy rain, and single-lane backroads.
However, there are incidents that the NHTSA has used to determine the need for this probe, at least for now. The agency said:
“Available incident data raise concerns that Tesla’s degradation detection system, both as originally deployed and later updated, fails to detect and/or warn the driver appropriately under degraded visibility conditions such as glare and airborne obscurants. In the crashes that ODI has reviewed, the system did not detect common roadway conditions that impaired camera visibility and/or provide alerts when camera performance had deteriorated until immediately before the crash occurred.”
It continues to say in its report that a review of Tesla’s responses revealed additional crashes that occurred in similar environments showed FSD “did not detect a degraded state, and/or it did not present the driver with an alert with adequate time for the driver to react. In each of these crashes, FSD also lost track of or never detected a lead vehicle in its path.”
The next steps of the NHTSA Engineering Analysis require the agency to gather further information on Tesla’s attempts to upgrade the degradation detection system. It will also analyze six recent potentially related incidents.
The investigation is listed as EA26002.
