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 Giga Nevada celebrates production of 6 millionth drive unit
To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo.
Tesla’s Giga Nevada has reached an impressive milestone, producing its 6 millionth drive unit as 2925 came to a close.
To celebrate the milestone, the Giga Nevada team gathered for a celebratory group photo.
6 million drive units
The achievement was shared by the official Tesla Manufacturing account on social media platform X. “Congratulations to the Giga Nevada team for producing their 6 millionth Drive Unit!” Tesla wrote.
The photo showed numerous factory workers assembled on the production floor, proudly holding golden balloons that spelled out “6000000″ in front of drive unit assembly stations. Elon Musk gave credit to the Giga Nevada team, writing, “Congrats on 6M drive units!” in a post on X.
Giga Nevada’s essential role
Giga Nevada produces drive units, battery packs, and energy products. The facility has been a cornerstone of Tesla’s scaling since opening, and it was the crucial facility that ultimately enabled Tesla to ramp the Model 3 and Model Y. Even today, it serves as Tesla’s core hub for battery and drivetrain components for vehicles that are produced in the United States.
Giga Nevada is expected to support Tesla’s ambitious 2026 targets, including the launch of vehicles like the Tesla Semi and the Cybercab. Tesla will have a very busy 2026, and based on Giga Nevada’s activities so far, it appears that the facility will be equally busy as well.

Tesla Supercharger network delivers record 6.7 TWh in 2025
The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets.
Tesla’s Supercharger Network had its biggest year ever in 2025, delivering a record 6.7 TWh of electricity to vehicles worldwide.
To celebrate its busy year, the official @TeslaCharging account shared an infographic showing the Supercharger Network’s growth from near-zero in 2012 to this year’s impressive milestone.
Record 6.7 TWh delivered in 2025
The bar chart shows steady Supercharger energy delivery increases since 2012. Based on the graphic, the Supercharger Network started small in the mid-2010s and accelerated sharply after 2019, when the Model 3 was going mainstream.
Each year from 2020 onward showed significantly more energy delivery, with 2025’s four quarters combining for the highest total yet at 6.7 TWh.
This energy powered millions of charging sessions across Tesla’s growing fleet of vehicles worldwide. The network now exceeds 75,000 stalls globally, and it supports even non-Tesla vehicles across several key markets. This makes the Supercharger Network loved not just by Tesla owners but EV drivers as a whole.
Resilience after Supercharger team changes
2025’s record energy delivery comes despite earlier 2024 layoffs on the Supercharger team, which sparked concerns about the system’s expansion pace. Max de Zegher, Tesla Director of Charging North America, also highlighted that “Outside China, Superchargers delivered more energy than all other fast chargers combined.”
Longtime Tesla owner and FSD tester Whole Mars Catalog noted the achievement as proof of continued momentum post-layoffs. At the time of the Supercharger team’s layoffs in 2024, numerous critics were claiming that Elon Musk was halting the network’s expansion altogether, and that the team only remained because the adults in the room convinced the juvenile CEO to relent.
Such a scenario, at least based on the graphic posted by the Tesla Charging team on X, seems highly implausible.
