SpaceX’s fourth Falcon booster delivery this year hints at rare production uptick
For at least the fourth time in 2021, SpaceX has shipped a new Falcon booster from its Hawthorne, California headquarters and factory to an expansive test and development campus in Central Texas.
By all appearances, SpaceX’s latest delivery could imply that the company is on track to experience its first Falcon booster production uptick in four years. Thanks almost exclusively to the overwhelming success of Falcon reusability, SpaceX has been decreasing booster production year over year since 2017 while (on the whole) still significantly increasing its annual launch cadence. However, that downward booster production trend may have finally come to an end in 2021.
On July 21st, spaceflight journalist Eric Berger spotted a SpaceX Falcon booster – almost impossible to miss on the road – traveling eastbound towards El Paso on a Texas highway. Designed from the start with a maximum diameter (3.6m/12′) explicitly limited to allow Falcon 9 and Falcon Heavy stages to be easily and cheaply transported by road, SpaceX has taken advantage of that capability by making Falcon rockets some of the most extensively tested launch vehicles on Earth.
Most notably, every single Falcon 9 and Falcon Heavy booster and upper stage SpaceX has ever built at its Hawthorne HQ has shipped to McGregor, Texas for qualification testing before being cleared to launch. The exact nature of that qualification testing is unknown but, at minimum, every SpaceX-built stage must eventually complete a clean static fire test before the company deems it qualified for flight and ships it to one of three launch pads.
Before integrated static fire testing, SpaceX also separately tests every single Merlin 1D, Merlin Vacuum, Draco engine, and cold gas thruster before they’re installed on their respective Falcon first stage, second stage, fairing, or Dragon spacecraft back in California. However, Falcon engines, fairings, second stages, and Dragon spacecraft are all small or well-packaged enough to be unassuming on the road. Only Falcon boosters – measuring some 4m (~13 ft) wide and 56m (~190 ft) long and usually wrapped in solid white or black plastic – are routinely spotted in the wild by members of the public.
Those regular public spottings provide the only real glimpse available behind the curtain of SpaceX’s prolific rocket production. Beyond a mishmash of observations from members of the public and the occasional tidbit from CEO Elon Musk, SpaceX – a private company in a very competitive industry – provides no official information about how many Falcon stages it produces each year. That leaves it up to unaffiliated fans to collate and track that activity.
In particular, one Reddit user went to the effort of combing through a decade of those observations to tabulate SpaceX’s annual Falcon first stage production – including Falcon 9 and Falcon Heavy boosters – since 2010. From 2010 to 2017, booster production consistently grew year over year, ultimately peaking at 13 – more than one booster per month – in 2017. Since 2017, booster production has consistently declined, dropping to just five boosters completed in 2020 – the lowest figure since 2013.
Of course, despite building just five new boosters in 2020, SpaceX completed a record 26 Falcon 9 launches, demonstrating just how much of a paradigm shift booster reusability has been for the company. Notably, while booster production has drastically decreased, SpaceX still has to manufacture a new expendable upper stage for every Falcon launch, meaning that – for the most part – Hawthorne is likely as busy as – and soon to be busier than – it was around the 2016-2018 peak.
In a bit of twist, though, that booster production downtick may have bottomed out in 2020. Since May 2020, SpaceX appears to have shipped at least 8 or 9 boosters* from Hawthorne to McGregor. Less than a month ago, a new booster – believed to be Falcon 9 B1069 – went vertical in McGregor ahead of its first wet dress rehearsal and static fire. Less than three weeks later, another new Falcon booster was spotted ready for transport outside of Hawthorne – likely the same booster spotted on its way to McGregor on July 21st.
*Including F9/FH boosters B1061, B1062, B1063, B1064, B1065, B1066, B1067, and B1069
In 2021, SpaceX has delivered one Falcon Heavy (likely B1066) and two Falcon 9 boosters (B1067 and B1069) to McGregor. The mystery booster seen in Hawthorne on July 18th – now likely inside a McGregor hangar as of publishing – is the fourth Falcon first stage to roll out of Hawthorne this year. If SpaceX maintains that average over the next five months, it could ship 6 or even 7 Falcon boosters in 2021 – marking the first apparent production uptick since 2017.

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 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).

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.
Cybertruck
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.
