SpaceX appears to be making great progress towards the start of its first full Super Heavy static fire campaign, building upon extensive Starship testing and a single booster static fire completed in July 2021.

On May 14th, upgraded Super Heavy booster B7 was moved back to SpaceX’s South Texas Starbase Starship factory after completing a successful round of tests and smoothing out an otherwise rocky start to its life. It was not the booster’s first time on that journey: after first leaving the Starbase ‘nest’ on March 31st, Booster 7 suffered significant internal damage during a structural stress test on April 14th and was forced to return to the factory for repairs. Impressively, despite the cramped environment and extremely limited access to the interior of the Super Heavy’s primary and secondary propellant tanks, SpaceX engineers and technicians somehow completed those repairs and Booster 7 sailed through a new round of ‘cryoproof’ testing on May 9th and 11th.

In the ~20 days since its second return, SpaceX teams have been hard at work preparing Super Heavy B7 for its next major challenges – the results of which could determine whether the massive rocket helps launch a Starship into space later this year.

That goal, same as it has been for half a year, is to qualify the first Super Heavy booster for flight. To do so, SpaceX must – at long last – static fire a Super Heavy with all necessary Raptor engines installed. For Booster 7 and its near-term successors, that means 33 new “Raptor 2” engines capable of generating a total of ~7600 metric tons (~16.7M lbf) of thrust.

That’s exactly what SpaceX workers have been focused on doing since Booster 7’s second return to a Starbase assembly bay. Bit by bit, they have spent every day since installing Raptor 2 engines one at a time. Unfortunately, due to the Super Heavy’s relocation inside a brand new assembly building known as the Megabay, High Bay 2, or Wide Bay, the half-dozen or so unaffiliated photographers who have come to regularly photograph Starbase have yet to find an angle that shows the state of that engine installation progress.

A Raptor 2 engine heads to Booster 7.

Two weeks later, it’s clear that SpaceX is taking its time, which likely also implies that the company is simultaneously encasing Booster 7’s Raptors and engine section in shrouds that will protect them during static fire testing; as well as during launch, reentry, and landing if B7 makes it that far. That’s not guaranteed, however, and it could also simply be that installing 33 engines on the first attempt at installing any Raptor 2s on any rocket has proven much harder than expected.

On June 1st, CEO Elon Musk appeared to confirm that engines are still being installed on Super Heavy B7, but he also verified that “all Raptor 2 engines needed for [the] first orbital flight are complete.” That could include Starship S24, which needs three sea-level Raptor 2s and three vacuum-optimized Raptor 2s, but it’s still great news even if he only means it for Booster 7. SpaceX has been spotted delivering at least a handful of new Raptor 2 engines a week for the last month or two, which means that all 33 engines may already be onsite at Starbase. If some are still undergoing proof testing at SpaceX’s McGregor, Texas facilities, it could be a few more weeks before all necessary engines are onsite, but that milestone is likely close at hand if it hasn’t already been reached.

For Super Heavy Booster 4, which was inexplicably never static-fired, installation of all 29 of its Raptor 1 engines took just a few days, but the installation of a heat shield around those engines took at least a few weeks. On June 1st, SpaceX also began installing grid fins on Super Heavy B7, further indicating the company’s growing confidence in the booster.

Outside of booster outfitting, SpaceX has also been aggressively refilling the Starbase orbital launch site’s (OLS) massive tank farm, which is capable of storing, subcooling, and distributing thousands of tons of liquid oxygen (LOx), liquid methane (LCH4), liquid nitrogen (LN2), and a variety of gases. For a full wet dress rehearsal (WDR), which has also never been done with Super Heavy, SpaceX would need to fill the booster with around 3400 tons (7.5M lb) of propellant. Out of an abundance of caution, Super Heavy B7 will likely have far less propellant aboard during almost all of its static fire tests, but a full static fire with a full load of propellant – simulating most prelaunch conditions – will likely be one of the last main goals of any static fire campaign. At full thrust, 33 Raptor 2 engines will likely burn around 25 tons (~55,000 lb) of propellant per second, so a huge amount of propellant will be needed regardless.

In the same series of June 1st tweets, Musk also confirmed that SpaceX intends to proceed cautiously into its first true Super Heavy static fire campaign, testing engines “just one at a time at first.” Musk probably isn’t being literal, as a campaign in which Booster 7 tested every one of its 33 Raptors individually could easily take weeks, so it’s likely safe to interpret his words to mean that SpaceX is not going to leap straight from the first limited test of one or a few engines to all 13 center engines, all 20 outer ‘boost’ engines, or all 33 engines at once.

Almost three weeks into the process of engine and heat shield installation, Booster 7 could potentially be ready to return to the orbital launch site any day now, though there’s probably an equal chance that it’s still a few weeks away. Nonetheless, SpaceX is on the cusp of kicking off one of the most exciting and important test campaigns in the history of Starship.

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.

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

Published

on

Credit: Tesla

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.

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.

Published

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.

Tesla provides Cybertruck Powershare release update

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.
