SpaceX’s next Falcon Heavy hits milestone as final rocket parts arrive in Florida
SpaceX has reached a critical milestone on the road to Falcon Heavy’s third flight: all major parts of the rocket – three boosters, an interstage, and a payload fairing – are now officially on-site at the company’s Pad 39A launch facilities.
This means that all that stands between SpaceX, the USAF, and the critical mission is the integration of the hardware into one vehicle, as well as the integration and encapsulation of all 24 customer satellites in the Falcon payload fairing. As noted by the USAF Space and Missile Systems Center (SMC), Falcon Heavy’s Space Test Program-2 (STP-2) mission will be exceptionally challenging and important for SpaceX for a variety of reasons.
Falcon Heavy: The Upper Stagening
Although the general performance of the three first stage boosters will be absolutely critical, the US Air Force’s STP-2 mission manages to cram in several additional major goals. First and foremost, all eyes will be on SpaceX’s Falcon upper stage (S2). Scheduled to last no less than several hours, the upper stage will be put through its paces like never before, requiring four separate ignitions and shutoffs of its Merlin Vacuum engine. For SpaceX, this may be the first time the company has ever attempted the feat – if any on-orbit testing has been done after completing customer missions, SpaceX has never commented on it.
Back in February 2018, Falcon Heavy’s launch debut also happened to mark the first flight-test of a true long-duration upper stage coast and third ignition, a spectacular success that sent Starman and a Tesla Roadster into a heliocentric orbit that now reaches beyond Mars. As such, SpaceX will by no means be walking into the challenges of STP-2 unprepared. In fact, the coast required on Flight 1 may have technically been more challenging than any one of the four separate burns S2 will need to perform on STP-2. However, combining the need to do all four burns and deployments rather quickly and in sequence, the critical need for accurate orbital insertions, and high standards of reliability and mission assurance expected by the USAF, STP-2 will easily be the hardest mission SpaceX has yet to attempt.
If SpaceX succeeds, the benefits will stretch far beyond simply satisfying an Air Force requirement and securing the USAF’s Falcon Heavy certification. Once SpaceX has rigorously demonstrated the reliability of Falcon 9’s upper stage for long coasts and high numbers of ignition events, the company will be able to apply that as a marketable product. Potential customers include the usual communications satellite operators desiring a direct-to-GEO insertion, saving time (and thus making money faster) by skipping the orbit-raising that comes with easier transfer orbits.
One major use-case – as demonstrated by Falcon Heavy’s interplanetary launch debut – is sending payloads beyond Earth orbit, a capability that NASA would undoubtedly take advantage of.
Reusability makes a surprise entrance
But wait, there’s more! In a predictable but still largely unexpected turn of events, the Air Force has also selected Falcon Heavy’s STP-2 mission as an opportunity to gain familiarity with the rocket reusability SpaceX is famous for. Falcon Heavy’s second mission and commercial launch debut – Arabsat 6A – used three all-new Block 5 boosters, two of which returned to land after gentle recoveries. Known as B1052 and B1053, the lightly-used boosters are now scheduled to become the first flight-proven orbital-class rockets launched on a Department of Defense (DoD) mission in 25 years, since the Space Shuttle’s final military mission in 1992.
If successful, SpaceX will help pave the way for the US military to seriously adopt reusable rockets and develop the “certification” procedures needed to do so. This will benefit all prospective US launch providers, not just SpaceX, but SpaceX will likely be the only company flying valuable payloads on flight-proven rockets until Blue Origin and ULA’s Vulcan achieve flight-proven certification for military launches. Much like regular certification often requires multiple launch demonstrations, flight-proven certification will likely be at least as – if not more – stringent. For New Glenn, that milestone might come as early as 2023-2025, while Vulcan – if a reusable engine section is ever actually implemented – is unlikely to even complete its launch debut – let alone first reuse – before 2025.
As such, SpaceX is quite literally half a decade ahead of its prospective competitors when it comes to certifying flight-proven rockets for high-value launches. Additionally, just the act of the USAF completing its development of a reusability certification process will likely encourage – if not directly lay the foundation for – NASA to seriously consider doing the same with its own launch services.

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.Â
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.Â

Tesla targets production increase at Giga Berlin in 2026
Plant manager AndrĂ© Thierig confirmed the facility’s stable outlook to the DPA, noting that Giga Berlin implemented no layoffs or shutdowns amid challenging market conditions.
Tesla is looking positively toward 2026 with plans for further growth at its GrĂĽnheide factory in Germany, following steady quarterly increases throughout 2025.
Plant manager AndrĂ© Thierig confirmed the facility’s stable outlook to the Deutsche Presse-Agentur (DPA), noting that Giga Berlin implemented no layoffs or shutdowns despite challenging market conditions.Â
Giga Berlin’s steady progress
Thierig stated that Giga Berlin’s production actually rose in every quarter of 2025 as planned, stating: “This gives us a positive outlook for the new year, and we expect further growth.” The factory currently supplies over 30 markets, with Canada recently being added due to cost advantages.
Giga Berlin’s expansion is still underway, with the first partial approval for capacity growth being secured. Preparations for a second partial approval are underway, though the implementation of more production capacity would still depend on decisions from Tesla’s US leadership.Â
Over the year, updates to Giga Berlin’s infrastructure were also initiated. These include the relocation of the Fangschleuse train station and the construction of a new road. Tesla is also planning to start battery cell production in Germany starting 2027, targeting up to 8 GWh annually.
Resilience amid market challenges
Despite a 48% drop in German registrations, Tesla maintained Giga Berlin’s stability. Thierig highlighted this, stating that “We were able to secure jobs here and were never affected by production shutdowns or job cuts like other industrial sites in Germany.”
Thierig also spoke positively towards the German government’s plans to support households, especially those with low and middle incomes, in the purchase and leasing of electric vehicles this 2026. “In our opinion, it is important that the announcement is implemented very quickly so that consumers really know exactly what is coming and when,” the Giga Berlin manager noted.Â
Giga Berlin currently employs around 11,000 workers, and it produces about 5,000 Model Y vehicles per week, as noted in an Ecomento report. The facility produces the Model Y Premium variants, the Model Y Standard, and the Model Y Performance.Â

Tesla revamped Semi spotted, insane 1.2 MW charging video releases
These developments highlight Tesla’s ongoing refinements to the vehicle’s design and infrastructure.
Tesla is gearing up for high-volume Semi production in 2026, with the Class 8 all-electric truck’s revamped variant being spotted in the wild recently. Official footage from Tesla also showed the Semi achieving an impressive 1.2 MW charging rate on a charger.Â
These developments highlight Tesla’s ongoing refinements to the vehicle’s design and infrastructure.
Revamped Tesla Semi sighting
Tesla Semi advocate @HinrichsZane, who has been chronicling the progress of the vehicle’s Nevada factory, recently captured exclusive drone footage of the refreshed Class 8 truck at a Megacharger stall near Giga Nevada. The white unit features a full-width front light bar similar to the Model Y and the Cybercab, shorter side windows, a cleared fairing area likely for an additional camera, and diamond plate traction strips on the steps.
Overall, the revamped Semi looks ready for production and release. The sighting marks one of the first real-life views of the Class 8 all-electric truck’s updated design, with most improvements, such as potential 4680 cells and enhanced internals, being hidden from view.
1.2 MW charging speed and a new connector
The official Tesla Semi account on X also shared an official video of Tesla engineers hitting 1.2 MW sustained charging on a Megacharger, demonstrating the vehicle’s capability for extremely rapid charging. Tesla Semi program lead Dan Priestley confirmed in a later post on X that the test occurred at a dedicated site, noting that chargers at the Semi factory in Nevada are also 1.2 MW capable.
The short video featured a revamped design for the Semi’s charging port, which seems more sleek and akin to the NACS port found in Tesla’s other vehicles. It also showed the Tesla engineers cheering as the vehicle achieved 1.2 MW during its charging session. Dan Priestley explained the Semi’s updated charging plug in a post on X.
“The connector on the prior Semi was an early version (v2.4) of MCS. Not ‘proprietary’ as anyone could have used it. We couldn’t wait for final design to have >1MW capability, so we ran with what had been developed thus far. New Semi has latest MCS that is set to be standard,” the executive wrote in a post on X.
