SpaceX begins Falcon Heavy booster deliveries for first launch in two years
SpaceX’s first Falcon Heavy rocket launch in almost two years has entered the final stages of preparations – flight hardware acceptance testing, delivery, and assembly.
Comprised of five major elements, the vast majority of the challenges of building and launching Falcon Heavy come from the rocket’s three first-stage boosters – each more or less equivalent to a single-core Falcon 9 booster. Falcon Heavy’s twin side boosters are by far the most visually recognizable sign of that similar-but-different nature thanks to the need for aerodynamic nosecones instead of a Falcon booster’s normal interstage (a hollow cylinder).
While easily recognizable, the center core is the most technically Falcon Heavy-specific part of SpaceX’s partially-reusable heavy-lift rocket, requiring a unique airframe relative to side cores, which are essentially Falcon 9 boosters with a few major add-ons. It’s one of those Falcon Heavy side boosters that was spotted traveling by road from SpaceX’s test facilities to a Florida launch pad on Tuesday, January 26th.
For unknown reasons, although SpaceX currently has two reused Falcon Heavy side boosters that flew a second time on the US Air Force’s own STP-2 mission, the company has manufactured all-new boosters – likely at the US military’s request – for the rocket’s fourth launch. Rebadged from AFSPC-44 to USSF-44, that mission will see SpaceX attempt its first-ever direct-to-GEO launch, nominally launching a several-ton mystery satellite directly into geostationary orbit (GEO).
The main challenge of direct-to-GEO launches is the need for a given rocket’s upper stage to coast for hours in orbit and then reignite after that multi-hour coast period. The direct launch profile also demands more delta-V (propellant) than alternative transfer orbits (GTOs) – propellant that must be launched into orbit in addition to the customer’s payload. That requires the use of extremely large and/or efficient rockets, which is why SpaceX is launching USSF-44 with Falcon Heavy instead of a much cheaper and simpler Falcon 9.
Unlike all other direct-to-GEO launches in history, however, Falcon Heavy Flight 4 will (hopefully) mark the first time a rocket launches a payload into geostationary orbit while still recovering a large portion of its first stage. After liftoff, Falcon Heavy side boosters B1064 and B1065 will attempt the first-ever dual drone ship landing at sea, while the rocket’s custom center core will be intentionally expended. According to CEO Elon Musk, that sacrificial-center-core configuration theoretically allows Falcon Heavy to achieve ~90% of its expendable performance while still recovering two otherwise reusable boosters.
As of the first USSF-44 side booster’s appearance in Louisiana, at least one other booster (most likely the mission’s second side booster) has already been spotted at SpaceX’s McGregor, Texas development facilities and may have already completed its own round of static fire acceptance testing. Given the three-month gap between the first USSF-44 side booster’s static fire and a side booster’s appearance in transport, there’s a distant possibility that the booster spotted on January 26th was the second of two side boosters to ship east, but that’s improbable given how much Falcon boosters stick out on the road.
Ultimately, assuming the second USSF-44 side booster’s static fire acceptance test went well, the only major Falcon Heavy-specific hardware SpaceX needs to ship from its Hawthorne, CA headquarters is center core B1066. An upper stage and payload fairing will also have to pass acceptance testing and head to Florida but both will likely be standard Falcon 9-issue hardware, minimizing small-batch uncertainty.
If SpaceX delivers B1066 to McGregor within the next week or two, the center core should be ready to ship to Florida by March or April, leaving SpaceX two or three months to integrate, static fire, and prepare Falcon Heavy for its fourth launch. According to the latest official information from the US military, USSF-44 is scheduled to launch no earlier than (NET) “late-spring 2021,” likely implying late-May or June.
Tesla Semi Program Director Dan Priestly teased the major improvements to the all-electric Class 8 truck on Thursday night, following the company’s decision to overhaul the design earlier this year.
Priestley said he drove the Semi on Thursday, and the improvements appear to be welcomed by one of the minds behind the project. “Our customers are going to love it,” he concluded.
Just drove the redesigned Semi. Our customers are going to love it. https://t.co/KZ88sf1CDL

The small detail does not seem like much, but it is coming from someone who has been involved in the development of the truck from A to Z. Priestley has been involved in the Semi program since November 2015 and has slowly worked his way through the ranks, and currently stands as the Director of the program.
Tesla Semi undergoes major redesign as dedicated factory preps for deliveries
Tesla made some major changes to the Semi design as it announced at the 2025 Annual Shareholder Meeting that it changed the look and design to welcome improvements in efficiency.
Initially, Tesla adopted the blade-like light bar for the Semi, similar to the one that is present on the Model Y Premium and the Cybertruck.
Additionally, there are some slight aesthetic changes to help with efficiency, including a redesigned bumper with improved aero channels, a smaller wraparound windshield, and a smoother roofline for better aero performance.
All of these changes came as the company’s Semi Factory, which is located on Gigafactory Nevada’s property, was finishing up construction in preparation for initial production phases, as Tesla is planning to ramp up manufacturing next year. CEO Elon Musk has said the Semi has attracted “ridiculous demand.”
The Semi has already gathered many large companies that have signed up to buy units, including Frito-Lay and PepsiCo., which have been helping Tesla test the vehicle in a pilot program to test range, efficiency, and other important metrics that will be a major selling point.
Tesla will be the Semi’s first user, though, and the truck will help solve some of the company’s logistics needs in the coming years.
Tesla is dominating in the United Kingdom so far through 2025, and with about two weeks left in the year, the Model Y and Model 3 are leading the way.
The Model Y and Model 3 are the two best-selling electric vehicles in the United Kingdom, which is comprised of England, Scotland, Wales, and Northern Ireland, and it’s not particularly close.
According to data gathered by EU-EVs, the Model Y is sitting at 18,890 units for the year, while the Model 3 is slightly behind with 16,361 sales for the year so far.
The next best-selling EV is the Audi Q4 e-tron at 10,287 units, lagging significantly behind but ahead of other models like the BMW i4 and the Audi Q6 e-tron.
GOOD NEWS 🇬🇧 Tesla is absolutely crushing the UK electric vehicle market in 2025 💥
The numbers are in, and the dominance is clear. With an impressive amount of 42,270 vehicles delivered year-to-date, the brand now commands a solid 9.6% market share of the total auto market 🆒… pic.twitter.com/dkiGX9kzd0

The Model Y has tasted significant success in the global market, but it has dominated in large markets like Europe and the United States.
For years, it’s been a car that has fit the bill of exactly what consumers need: a perfect combination of luxury, space, and sustainability.
Both vehicles are going to see decreases in sales compared to 2024; the Model Y was the best-selling car last year, but it sold 32,610 units in the UK. Meanwhile, the Model 3 had reached 17,272 units, which will keep it right on par with last year.
Tesla sold 50,090 units in the market last year, and it’s about 8,000 units shy of last year’s pace. It also had a stronger market share last year with 13.2 percent of the sales in the market. With two weeks left in 2025, Tesla has a 9.6 percent market share, leading Volkswagen with 8 percent.
The company likely felt some impact from CEO Elon Musk’s involvement with the Trump administration and, more specifically, his role with DOGE. However, it is worth mentioning that some months saw stronger consumer demand than others. For example, sales were up over 20 percent in February. A 14 percent increase followed this in June.

Tesla Insurance officially expands to new U.S. state
Tesla’s in-house Insurance program first launched back in late 2019, offering a new way to insure the vehicles that was potentially less expensive and could alleviate a lot of the issues people had with claims, as the company could assess and repair the damage itself.
Tesla Insurance has officially expanded to a new U.S. state, its thirteenth since its launch in 2019.
Tesla has confirmed that its in-house Insurance program has officially made its way to Florida, just two months after the company filed to update its Private Passenger Auto program in the state. It had tried to offer its insurance program to drivers in the state back in 2022, but its launch did not happen.
Instead, Tesla refiled the paperwork back in mid-October, which essentially was the move toward initiating the offering this month.
BREAKING: Tesla Insurance has just officially launched in Florida.
This is the first new state to receive @Tesla Insurance in more than 3 years. In total, Tesla insurance is now available in 13 U.S. states (map in thread below of all the states).

Tesla’s in-house Insurance program first launched back in late 2019, offering a new way to insure the vehicles that was potentially less expensive and could alleviate a lot of the issues people had with claims, as the company could assess and repair the damage itself.
It has expanded to new states since 2019, but Florida presents a particularly interesting challenge for Tesla, as the company’s entry into the state is particularly noteworthy given its unique insurance landscape, characterized by high premiums due to frequent natural disasters, dense traffic, and a no-fault system.
Annual average premiums for Florida drivers hover around $4,000 per year, well above the national average. Tesla’s insurance program could disrupt this, especially for EV enthusiasts. The state’s growing EV adoption, fueled by incentives and infrastructure development, aligns perfectly with Tesla’s ecosystem.
Moreover, there are more ways to have cars repaired, and features like comprehensive coverage for battery damage and roadside assistance tailored to EVs address those common painpoints that owners have.
However, there are some challenges that still remain. Florida’s susceptibility to hurricanes raises questions about how Tesla will handle claims during disasters.
Looking ahead, Tesla’s expansion of its insurance program signals the company’s ambition to continue vertically integrating its services, including coverage of its vehicles. Reducing dependency on third-party insurers only makes things simpler for the company’s automotive division, as well as for its customers.
