SpaceX's next Starship rapidly coming together as Elon Musk shares latest progress
SpaceX CEO Elon Musk has shown off a rarely-seen phase of Starship construction, further confirming that the next full-scale rocket ship is rapidly coming together after operator error destroyed its predecessor on April 3rd.
Around 5 am local time (10:00 UTC) on April 5th, Musk shared a photo of a smaller secondary tank’s installation inside Starship SN4’s full-size liquid methane tank. The photo is the first time SpaceX or its CEO has offered a glimpse inside this lesser-known part of Starship production and assembly and simultaneously offers insight into a design that’s been a mystery for months. Over the last few weeks, local residents-turned-unofficial-SpaceX-photographers have captured several photos of an internal Starship header tank design far removed from the nosecone tank Musk has previously discussed.
Those header tanks are a necessity to enable Starship’s ability to quickly, reliably, and safely reignite its Raptor engines for recovery and landing-related burns. For a ship like Starship SN4, those header tanks are a sign that SpaceX may want to use the ship to perform Starship’s most crucial test short of orbit — a ~20 km (12.5 mi) flight test meant to demonstrate a skydiver-style landing maneuver. While that skydiver landing test remains several consecutive milestones distant, Musk’s April 5th photo confirms that Starship SN4 is making significant progress towards final assembly.
Known as header tanks, SpaceX’s large Starship launch vehicle upper stage and orbital spacecraft requires smaller, secondary tanks aside from the main liquid oxygen and methane propellant tanks that make up the bulk of its body. In these early stages of prototype development, those tanks serve one main purpose: reserve a small portion of pressurized propellant for Starship landing burns.
While Starship’s main tanks still need to be pressurized at all times to ensure the rocket’s structural integrity, smaller header tanks make it much easier to safely feed Raptor engines fuel during even the most chaotic of aerial maneuvers. For rocket engines, even the slightest introduction of pressurization gas or voids into the combustion process can lead to immediate destruction — a bit like how a tiny air bubble can be almost instantly fatal for humans. Starship header tanks thus ensure that only a fraction of the overall tank volume is in play during the ship’s most critical maneuvers.
Requiring both a fuel and oxidizer, Starships thus need two header tanks. Currently, Starship’s design places the liquid methane header tank directly inside the main methane tank itself. The liquid oxygen header tank, however, is situated in the very tip of Starship’s nose section, a location chosen to optimize the vehicle’s center of gravity for stability during a radical skydiver-style landing maneuver.
Musk’s April 5th photo and caption revealed that SpaceX began installing Starship SN4’s methane header tank just an hour or two after it had flipped the ship’s partially-completed liquid methane tank dome. Thanks to SpaceX’s more efficient use of a common dome design in their Falcon and Starship rockets, that dome also serves as the upper dome of the ship’s larger liquid oxygen tank. After the methane header tank is installed, a funnel-like sump will be the last addition needed to finish the section.
With the majority of Starship SN4 already in work around SpaceX’s Boca Chica, Texas rocket factory, the ship could be just a week or less away from kicking off the stacking phase of assembly. Stay tuned!

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.

Tesla targets production increase at Giga Berlin in 2026
Plant manager André 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 Grünheide factory in Germany, following steady quarterly increases throughout 2025.
Plant manager André 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.
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.
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.
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.

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.
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.
