Over the last few weeks, SpaceX’s Florida Starship launch pad construction has made some major progress and the structure that will one day support the first East Coast Starship and Super Heavy flight tests have grown several stories tall and show no signs of slowing down.
In a bid to make what could otherwise be an extremely expensive and time-consuming ordeal much faster and cheaper, SpaceX’s Starship/Super Heavy launch pads will be quite a bit different from the company’s several existing launch pads. This includes Kennedy Space Center’s LC-39A pad, leased and operated by SpaceX for Falcon Heavy and Crew Dragon missions and formerly used for dozens of Space Shuttle launches and all Saturn V Apollo Moon missions.
In a very on-brand move, SpaceX has decided to build Starship’s East Coast orbital pad within the bounds of Pad 39A but without using the pad’s existing launch mount or concrete flame trench. Instead, SpaceX is building a separate steel mount and water-cooled thruster diverter designed to stand up to the fury of a Super Heavy booster without allowing the rocket’s plume to dig a crater in the ground after ever ignition.
While choosing to pursue a dramatically different launch pad design for Starship may at first glance seem risky, SpaceX actually has more than a decade of experience building and operating similar mount and flame diverter setups at its McGregor, Texas rocket development and test facilities. A step further, NASA itself once heavily relied on similar technologies and strategies to rapidly build, test, and fly rockets larger than anything that came before them.
Most notably, the Saturn I rocket that preceded the massive Saturn V used a launch mount and flame diverter that looks quite similar to a conceptual setup SpaceX recently showed off in an updated Starship launch render.
SpaceX’s Starship mount is substantially taller, has gone with steel instead of reinforced concrete, and will have a fixed flame deflector, but the similarities are otherwise significant. Conceptually, both mounts are topped with a flat surface with numerous support arms and a large cutout for the rocket to sit atop and its exhaust to exit through. Similar to Falcon 9, the single-core Super Heavy booster mount shown in SpaceX renders will likely have four hold-down clamps and two tail service masts (TSMs), umbilical connections that supply the rocket with propellant, electricity, connectivity, and any other required fluids.
As described and pictured above, Starship’s Pad 39A launch mount has rapidly grown from a few metal beams into a major structure in just the last few weeks. By rough estimate, the existing mount is already 20 or so meters (70+ ft) tall and has large mounts for the installation of additional structures on top of it, while the conceptual mount shown in SpaceX renders appears to be about 25-30 m (80-100 ft) tall.
In the last few days, technicians have begun installing the first framework of the flame diverter SpaceX will use to prevent Starship from damaging itself or its surroundings during static fires and launches. Given the fact that Starship’s Super Heavy booster – as currently described – will be the single most powerful launch vehicle in history, such a vast amount of energy is not easy to dissipate. To accomplish that task, SpaceX revealed in August 2019 planning documents that the 39A diverter would be water-cooled.
The largest thrust diverter SpaceX has built supports the company’s McGregor, Texas booster test stand and has supported dozens upon dozens of integrated static fire tests. Originally designed to enable integrated triple-booster Falcon Heavy testing, SpaceX ultimately decided not to use that capability but the diverter is still immense, likely measuring at least 15m (50 ft) tall and 10m (33 ft) wide. By building dozens of pipes into the surface and structure of the diverter and filling those pipes with recirculating water, it can survive several minutes of hot rocket exhaust without suffering catastrophic erosion or outright melting.
It’s safe to say that Super Heavy will require a diverter that is far larger still to survive thrust equivalent to more than three Falcon Heavy rockets, but that very diverter and launch mount are already well on their way to completion at SpaceX’s Kennedy Space Center launch pad.

Tesla FSD (Supervised) is about to go on “widespread” release
In a comment last October, Elon Musk stated that FSD V14.2 is “for widespread use.”
Tesla has begun rolling out Full Self-Driving (Supervised) V14.2, and with this, the wide release of the system could very well begin.
The update introduces a new high-resolution vision encoder, expanded emergency-vehicle handling, smarter routing, new parking options, and more refined driving behavior, among other improvements.
FSD V14.2 improvements
FSD (Supervised) V14.2’s release notes highlight a fully upgraded neural-network vision encoder capable of reading higher-resolution features, giving the system improved awareness of emergency vehicles, road obstacles, and even human gestures. Tesla also expanded its emergency-vehicle protocols, adding controlled pull-overs and yielding behavior for police cars, fire trucks, and ambulances, among others.
A deeper integration of navigation and routing into the vision network now allows the system to respond to blocked roads or detours in real time. The update also enhances decision-making in several complex scenarios, including unprotected turns, lane changes, vehicle cut-ins, and interactions with school buses. All in all, these improvements should help FSD (Supervised) V14.2 perform in a very smooth and comfortable manner.
Elon Musk’s predicted wide release
The significance of V14.2 grows when paired with Elon Musk’s comments from October. While responding to FSD tester AI DRIVR, who praised V14.1.2 for fixing “95% of indecisive lane changes and braking” and who noted that it was time for FSD to go on wide release, Musk stated that “14.2 for widespread use.”
FSD V14 has so far received a substantial amount of positive reviews from Tesla owners, many of whom have stated that the system now drives better than some human drivers as it is confident, cautious, and considerate at the same time. With V14.2 now rolling out, it remains to be seen if the update also makes it to the company’s wide FSD fleet, which is still populated by a large number of HW3 vehicles.

Tesla FSD V14.2 starts rolling out to initial batch of vehicles
It would likely only be a matter of time before FSD V14.2 videos are posted and shared on social media.
Tesla has begun pushing Full Self-Driving (Supervised) v14.2 to its initial batch of vehicles. The update was initially observed by Tesla owners and veteran FSD users on social media platform X on Friday.
So far, reports of the update have been shared by Model Y owners in California whose vehicles are equipped with the company’s AI4 hardware, though it would not be surprising if more Tesla owners across the country receive the update as well.
Based on the release notes of the update, key improvements in FSD V14.2 include a revamped neural network for better detection of emergency vehicles, obstacles, and human gestures, as well as options to select arrival spots.

The Tesla Model X has always been one of the company’s most loved vehicles, despite its low sales figures, which can be attributed to its high price tag.
However, the Model X has been a signature item on Tesla’s menu of cars, most notably recognized by its Falcon Wing Doors, which are aware of its surroundings and open according to what’s around it.
But recent improvements to the Model X were looking slim to none, but it appears most of the fixes actually happened under the body, at least according to Tesla’s Vice President of Powertrain, Lars Moravy.
In a recent interview with Car and Driver, Moravy detailed all of the changes to the 2026 iteration of the vehicle, which was about 400 pounds lighter than it was originally. The biggest change is a modification with the rear motor, switching from an induction-type motor to a permanent-magnet design and optimizing the half-shafts, which shed about 100 pounds.
Tesla also got “almost 80 pounds out of the interior bits and pieces,” which “included making parts thinner, different manufacturing process choices, and incorporating airbag-deployment requirements into the headliner fabric,” the report said.
Additionally, the standard five-passenger, bench seat configuration saved 50 pounds by ditching pedestal mounting. This also helped with practicality, as it helped the seat fold flat. Engineers at Tesla also saved 44 pounds from the high-voltage wiring through optimizing the wiring from the charge-port DC/DC converter and switching from copper to aluminum wiring.
Tesla makes a decision on the future of its flagship Model S and Model X
Tesla also simplified the cooling system by reducing the number of radiators. It also incorporated Nürburgring cooling requirements for the Plaid variant, which saved nearly 30 pounds.
Many Tesla fans will be familiar with the megacastings, manufactured in-house by presses from IDRA, which also saves more than 20 pounds and boosts torsional stiffness by around 10 percent. Tweaks to the suspension also saved 10 pounds.
People were truly disappointed with what Tesla did with the Model S and Model X, arguing that the cars needed a more severe exterior overhaul, which might be true. However, Tesla really did a lot to reduce the weight of the vehicle, which helps increase range and efficiency. According to Grok, every 200 pounds removed adds between 7 and 15 percent to range estimations.
This makes sense considering the range estimations both increased by 7 percent from the Model X’s 2025 configuration to the 2026 builds. Range increased on the All-Wheel-Drive trim from 329 miles to 352 miles, while the Plaid went from 314 miles to 335 miles.
