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 Full Self-Driving’s newest behavior is the perfect answer to aggressive cars
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
Tesla Full Self-Driving appears to have a new behavior that is the perfect answer to aggressive drivers.
According to a recent video, it now appears the suite will automatically pull over if there is a tailgater on your bumper, the most ideal solution for when a driver is riding your bumper.
With FSD’s constantly-changing Speed Profiles, it seems as if this solution could help eliminate the need to tinker with driving modes from the person in the driver’s seat. This tends to be one of my biggest complaints from FSD at times.
A video posted on X shows a Tesla on Full Self-Driving pulling over to the shoulder on windy, wet roads after another car seemed to be following it quite aggressively. The car looks to have automatically sensed that the vehicle behind it was in a bit of a hurry, so FSD determined that pulling over and letting it by was the best idea:
Tesla appears to be implementing some sort of feature that will now pull over if someone is tailgating you to let the car by
Really cool feature, definitely get a lot of this from those who think they drive race cars

We can see from the clip that there was no human intervention to pull over to the side, as the driver’s hands are stationary and never interfere with the turn signal stalk.
This can be used to override some of the decisions FSD makes, and is a great way to get things back on track if the semi-autonomous functionality tries to do something that is either unneeded or not included in the routing on the in-car Nav.
FSD tends to move over for faster traffic on the interstate when there are multiple lanes. On two-lane highways, it will pass slower cars using the left lane. When faster traffic is behind a Tesla on FSD, the vehicle will move back over to the right lane, the correct behavior in a scenario like this.
Perhaps one of my biggest complaints at times with Full Self-Driving, especially from version to version, is how much tinkering Tesla does with Speed Profiles. One minute, they’re suitable for driving on local roads, the next, they’re either too fast or too slow.
When they are too slow, most of us just shift up into a faster setting, but at times, even that’s not enough, see below:
What has happened to Mad Max?
At one point it was going 32 in a 35. Traffic ahead had pulled away considerably https://t.co/bjKvaMVTNX pic.twitter.com/aaZSWmLu5v

There are times when it feels like it would be suitable for the car to just pull over and let the vehicle that is traveling behind pass. This, at least up until this point, it appears, was something that required human intervention.
Now, it looks like Tesla is trying to get FSD to a point where it just knows that it should probably get out of the way.

Tesla Megapack powers $1.1B AI data center project in Brazil
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
Tesla’s Megapack battery systems will be deployed as part of a 400MW AI data center campus in Uberlândia, Brazil. The initiative is described as one of Latin America’s largest AI infrastructure projects.
The project is being led by RT-One, which confirmed that the facility will integrate Tesla Megapack battery energy storage systems (BESS) as part of a broader industrial alliance that includes Hitachi Energy, Siemens, ABB, HIMOINSA, and Schneider Electric. The project is backed by more than R$6 billion (approximately $1.1 billion) in private capital.
According to RT-One, the data center is designed to operate on 100% renewable energy while also reinforcing regional grid stability.
“Brazil generates abundant energy, particularly from renewable sources such as solar and wind. However, high renewable penetration can create grid stability challenges,” RT-One President Fernando Palamone noted in a post on LinkedIn. “Managing this imbalance is one of the country’s growing infrastructure priorities.”
By integrating Tesla’s Megapack systems, the facility will function not only as a major power consumer but also as a grid-supporting asset.
“The facility will be capable of absorbing excess electricity when supply is high and providing stabilization services when the grid requires additional support. This approach enhances resilience, improves reliability, and contributes to a more efficient use of renewable generation,” Palamone added.
The model mirrors approaches used in energy-intensive regions such as California and Texas, where large battery systems help manage fluctuations tied to renewable energy generation.
The RT-One President recently visited Tesla’s Megafactory in Lathrop, California, where Megapacks are produced, as part of establishing the partnership. He thanked the Tesla team, including Marcel Dall Pai, Nicholas Reale, and Sean Jones, for supporting the collaboration in his LinkedIn post.

Starlink powers Europe’s first satellite-to-phone service with O2 partnership
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools.
Starlink is now powering Europe’s first commercial satellite-to-smartphone service, as Virgin Media O2 launches a space-based mobile data offering across the UK.
The new O2 Satellite service uses Starlink’s low-Earth orbit network to connect regular smartphones in areas without terrestrial coverage, expanding O2’s reach from 89% to 95% of Britain’s landmass.
Under the rollout, compatible Samsung devices automatically connect to Starlink satellites when users move beyond traditional mobile coverage, according to Reuters.
The service initially supports text messaging along with apps such as WhatsApp, Facebook Messenger, Google Maps and weather tools. O2 is pricing the add-on at £3 per month.
By leveraging Starlink’s satellite infrastructure, O2 can deliver connectivity in remote and rural regions without building additional ground towers. The move represents another step in Starlink’s push beyond fixed broadband and into direct-to-device mobile services.
Virgin Media O2 chief executive Lutz Schuler shared his thoughts about the Starlink partnership. “By launching O2 Satellite, we’ve become the first operator in Europe to launch a space-based mobile data service that, overnight, has brought new mobile coverage to an area around two-thirds the size of Wales for the first time,” he said.
Satellite-based mobile connectivity is gaining traction globally. In the U.S., T-Mobile has launched a similar satellite-to-cell offering. Meanwhile, Vodafone has conducted satellite video call tests through its partnership with AST SpaceMobile last year.
For Starlink, the O2 agreement highlights how its network is increasingly being integrated into national telecom systems, enabling standard smartphones to connect directly to satellites without specialized hardware.
