SpaceX’s second Falcon Heavy booster arrives in Florida as launch #2 closes in
SpaceX’s second Falcon Heavy side booster has made its way from Texas to Florida after completing a successful static fire acceptance test at the company’s McGregor complex, paving the way for the third and final booster – currently vertical on McGregor’s test stand – to complete its own round of tests and head East.
Once the third and most important booster – known as the center core – arrives at SpaceX’s Florida launch facilities, all three of the next Falcon Heavy’s boosters will be ready to head into the integration stage, culminating in an integrated static fire prior to the second launch ever of SpaceX’s flagship super-heavy-lift rocket.

A Texas pilot happened to fly by SpaceX’s McGregor facilities on January 11th, catching a live glimpse of a Merlin Vacuum (MVac) or second stage static fire test, as well a Falcon booster – perhaps Falcon Heavy’s next center core – vertical on the facility’s booster static fire stand. While it has not yet been visually confirmed as the next Falcon Heavy center core, a booster traveling through the Waco, Texas area to McGregor was spotted with protuberances that are not normally seen on regular Falcon 9 boosters and happened to be in the right place for FH-specific hardware.

There is also a case to be made that – per the fact that the first two side boosters have been built, shipped, tested, and delivered back-to-back – SpaceX chose to consecutively manufacture all hardware needed for the second Falcon Heavy instead of producing one or a few single-stick Falcon 9 boosters in between, which the appearance of a center core-like rocket in Texas certainly helps corroborate. While Falcon Heavy side boosters are effectively just Falcon 9 boosters with a few additional attachments and nose cones, currently scheduling indicates that SpaceX may attempt to rapidly turn all three Falcon Heavy Flight 2 boosters around perhaps just 30-60 days after their first launch. Otherwise, once the rocket’s 2019 launches have been completed, both side boosters can be converted back into Falcon 9 boosters and thus reenter SpaceX’s active fleet of flight-proven rockets.
Falcon Heavy’s center core, however, is dramatically different than a regular Falcon 9 booster, owing to the fact that it needs to essentially support triple the thrust and mechanical stresses as single-stick launches. The rocket’s design works to improve payload performance by using the two side cores to boost the center core and leave it with far more propellant left over than Falcon 9 would during a comparable launch profile, roughly equivalent to a three-person bike where only two people are pedaling hard. During a Falcon Heavy launch, side boosters thus separate a solid 30-60 seconds before the center core parts ways with the upper stage and payload.

Thanks to its significant differences, it’s highly unlikely – if not impossible – for a Falcon Heavy center core to launch a regular Falcon 9 mission. As such, once Falcon Heavy’s 2019 launches are completed, the center core will most likely be processed, refurbished, and then stored until the next Falcon Heavy payload is ready to go, at which point Falcon 9 boosters would be converted into Heavy side cores. Given that the Block 5 upgrade is designed to allow Falcon boosters to perform as many as 10 launches with minimal to no refurbishment and 100+ with regular repairs and maintenance, it’s entirely possible that a single Falcon Heavy center core could theoretically support all possible future launches of the rocket.
In reality, customers like the USAF and NASA will probably request new hardware for foreseeable Falcon Heavy launches, most of which would likely be extremely expensive flagship satellites (AFSPC-52) or interplanetary spacecraft (Europa Clipper).
Fans of @SpaceX will be interested to note that the government is now taking very seriously the possibility of flying Clipper on the Falcon Heavy.

Falcon Heavy’s next two launches are planned as early as March (a large communications satellite called Arabsat 6A) and April (an experimental USAF launch called STP-2 with two dozen separate payloads). With two side boosters already in Florida, those dates are now serious possibilities, and the center core’s arrival will be the telltale sign that Falcon Heavy’s second launch ever is imminent.

Tesla gives the Roadster an official “Go for launch” demonstration date
Tesla teased an October 1 Roadster reveal, reviving years of delayed SpaceX thruster hover promises.
Tesla teased an October 1 event date for its next generation Roadster, posting an image on X Saturday that shows the car lit up like it is sitting on a launch pad, with the date “10.01” stamped across the bottom and the caption “Go for launch.” A countdown clock on Tesla’s Roadster order page now points to the same date, which falls on a Thursday. The company has not said where the event will happen or whether it will be streamed at the moment. Stay with us @Teslarati for live updates.

Tesla has since sent formal invitations to reservation holders confirming the event will take place in Waco, Texas, about 90 minutes north of its Austin headquarters, based on a digital ticket shared on X by Sawyer Merritt. Tesla did not name the exact venue, though Waco sits close to SpaceX’s McGregor, Texas, rocket test site, previously reported as the planned location for a Roadster thruster demonstration. The invite sets the reveal for 8:30 p.m. Eastern on October 1, requires RSVPs by midnight on September 16, and limits entry to guests 21 and older. Invitations are non-transferable.
The tease follows nine years of a project defined by unimaginable specs along with slipped dates. Musk first showed the second generation Roadster in November 2017 as a surprise reveal at the end of the Tesla Semi event, promising a 0 to 60 mph time under two seconds, a top speed above 250 mph, 620 miles of range from a 200 kWh battery, and production starting in 2020. At last November’s shareholder meeting, Musk set an April 1 demo date and joked the choice gave him “deniability” if it slipped again, which it did, moving first to late April, then to “a month or so,” then to August.
Tesla Roadster SpaceX Package’s 1.1-second 0-60 mph launch visualized in concept video
Whatever Tesla shows on October 1 is expected to center on the SpaceX developed thruster package Musk has described since 2018. Internally code named A71, a nod to the Lockheed SR-71 Blackbird, the system reportedly uses cold gas thrusters fed by a composite overwrapped pressure vessel, the same tank design SpaceX uses on Falcon 9. Musk has said a thruster equipped Roadster could hit 60 mph in about 1.1 seconds under roughly 2.75 g of launch force, well past the 1.9 second figure quoted for the standard car. That version reportedly will not be street legal and has reportedly been discussed as a limited run sold through a track only program.
The standard Roadster is still expected to carry the original $200,000 base price and $250,000 Founders Series tier, both set when Tesla opened $50,000 and $250,000 reservations in 2017. Tesla VP of Vehicle Engineering Lars Moravy has confirmed production will happen at Gigafactory Texas, with Musk targeting 2027 or 2028, 12 to 18 months after whatever the company demonstrates next month.

Tesla plans big safety improvements for Full Self-Driving v15
Tesla is planning to roll out some pretty significant safety and accident avoidance features with Full Self-Driving version 15, which will be the next major FSD deployment from the company.
Tesla AI lead Ashok Elluswamy used a near-miss this week to preview what the company says is the next leap in Full Self-Driving.
In response to a driver whose car had swerved away from another vehicle pulling out of a parking lot, Elluswamy wrote that he was glad the owner was safe and that “even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance” would arrive with FSD v15.
Glad you are safe. Even earlier prediction of hazards, even faster reaction time and overall significantly better safety and collision avoidance coming as part of the next big upgrade (v15).
— Ashok Elluswamy (@aelluswamy) September 11, 2026
The comment landed as Tesla continues to treat software as the primary safety upgrade path. v15 is described internally as a larger architectural step, with a much bigger neural network and tighter coupling between prediction and control.
The company has already begun using early v15 software in some robotaxi operations while rolling out safety features such as Automatic Collision Evasion into current customer cars, allowing the driving stack to intervene even when the driver is in manual control.
Tesla is rolling out a new FSD version with a massive safety addition
Tesla’s published telemetry is the backbone of its safety argument. In recent North American Vehicle Safety Report data, vehicles with FSD (Supervised) engaged traveled roughly 5.1 million to 5.7 million miles between major collisions, defined as airbag-deployment events.
Tesla’s estimate of the U.S. average over the same period is about 699,000 miles per comparable crash. That is the comparison Tesla often frames as roughly seven times fewer major collisions.
A tighter comparison uses the same Tesla fleet. Cars driven manually with active safety features such as automatic emergency braking still recorded a major collision about every 2.1 million miles. Against that baseline, FSD’s advantage shrinks to roughly 2.4 to 2.7 times fewer severe crashes, which independent researchers argue is the more apples-to-apples figure.
European data released in 2026 pointed in the same direction: Tesla reported FSD as 3.5 times safer than manual driving in the Netherlands and 4.1 times fewer collisions than manually driven Teslas with active safety across more than 100 million kilometers in five approved countries.
Those numbers do not settle every debate. NHTSA’s Standing General Order still shows Tesla accounting for the large majority of U.S. Level 2 driver-assist crash reports, in part because the fleet logs far more assisted miles than rivals. Critics also note that Tesla’s “U.S. average” mixes crash definitions and driving mix.
Even so, Tesla’s own same-car comparisons, plus lower rates of automatic emergency braking and harsh maneuvers when FSD is engaged, are the evidence Elluswamy is pointing to when he says v15 will push prediction and collision avoidance further. The claim is not that software already eliminates risk. It is that each major version is meant to widen the gap between the system and an unaided human driver.

Tesla’s most delayed Cybertruck feature is finally here
Tesla finally links Cybertruck Powershare with Powerwall 3 for extended home backup after years overdue.
Tesla’s Cybertruck can now pair with a Powerwall 3 to keep a house running longer during an outage, a feature the company first promised when the truck launched in November 2023.
The official Cybertruck account posted the update on X Thursday: “Powerwall 3 & I can now power your house together. This extends your home backup by over 3 days, equivalent to 9 additional Powerwalls,” Cybertruck lead engineer Wes Morrill confirmed the rollout separately, calling it the first time a vehicle and a home battery have worked together this way. Powerwall 2 and Powerwall+ compatibility is still coming later this year, per both the Cybertruck account and Morrill.

Powershare itself is not new. Tesla enabled the version that lets Cybertruck power tools, appliances or another EV through its bed outlets when the truck launched in 2023. Home backup through a Powershare Gateway and Universal Wall Connector arrived in 2024, and Tesla extended that support to homes with solar the following year. What has been missing until now is Powershare working alongside an existing Powerwall, instead of functioning as a separate backup source competing for the same job.
The pairing matters because a single Powerwall home battery typically covers a home for about a day, less if usage is heavy or the outage stretches into a heat wave or freeze. A second Powerwall for more backup storage costs several thousand dollars installed. A Cybertruck instead uses a battery the owner already has, one large enough here to add roughly three more days of backup without mounting another unit or booking an installer visit. For households in wildfire, hurricane or winter storm regions where outages run past a day, that keeps the refrigerator and medical equipment running instead of shutting down.
The company told owners in October 2024 that Powerwall integration was coming sometime in 2025. That date passed, and in December 2025 Tesla pushed the target to mid-2026, with Morrill explaining at the time that two grid-forming devices need to negotiate which one manages a home during an outage, and that certifying the process across multiple generations of Powerwall took longer than expected.
For owners who bought Powershare hardware expecting it to work with whatever battery setup they already had, Thursday’s update closes a gap that has shown up repeatedly in owner complaints since Cybertruck deliveries began. Tesla has also rolled out a separate Powershare grid support program in Texas, letting Cybertrucks send power back to the grid during high demand events, so the truck’s role in a home’s energy setup keeps expanding even as individual pieces of it arrive later than promised.
