SpaceX Starship launch pad upgraded as Elon Musk reveals rocket production milestone
SpaceX has begun to upgrade its South Texas Starship launch pad in anticipation of the completion of the next full-scale rocket prototype, photos of which CEO Elon Musk revealed just hours ago.
Working in parallel with efforts to repair damage caused by Starship serial number 1’s (SN1) violent February 28th test failure, SpaceX has managed to build, complete, and test an entirely separate ‘test tank’ and complete fabrication of a second full-scale Starship in a handful of weeks. Flexing the growing capabilities of the impressive Boca Chica, Texas Starship factory SpaceX has sprung up in just three months, the company is working around the clock to build not just one – but several – Starship prototypes simultaneously.
A successful March 9th tank test designed to prove a new thrust structure design managed to do just that less than two weeks after the same faulty part brought about Starship SN1’s demise. In the two weeks since that its test completion, SpaceX has been busy welding, stacking, welding, and stacking several separate sections of the next Starship prototype, known as SN3. Potentially a matter of days away from structural completion, focus has recently shifted to the launch pad the ship will be tested at. In the last few days, SpaceX technicians have begun to install a bizarre, new structural element on the mount Starship SN3 will be secured on top of, hinting at the goals of the rocket’s first test campaign.
Squeezing in alongside efforts to repair the propellant lines that run into the launch mount, upgrades began on March 24th as a SpaceX team worked to install what looked like an incredibly sturdy tripod (with four ‘legs’, of course). Thanks to familiar testing done with SpaceX’s most recent Starship tank prototype, the purpose of the launch mount’s newest appendage quickly became clear.
During the Starship SN2 tank’s thrust structure (‘thrust puck’, per Elon Musk) test campaign, SpaceX debuted the concurrent use of a beefy hydraulic jack to simulate the forces a Raptor engine static might produce. Capable of producing upwards of 200 metric tons (440,000 lbf) of thrust at full power, SpaceX will likely begin Starship static fire tests with a single Raptor engine. As soon as a Starship prototype completes one or several single-engine test fires, the plan is to install three sea level-optimized Raptor engines and repeat static fire tests.
Before that triple-engine static fire milestone, a first for the cutting-edge Raptor engine, SpaceX needs to verify that Starship’s thrust structure can stand up to the ~600 tons (~1.3M lbf) of force it will be subjected to during such a test. Sitting on a much smaller stand, Starship SN2 used a single hydraulic jack and temporary stand to simulate a single engine’s thrust. Starship SN3, sitting much higher above the ground, will need three jacks to simulate three Raptors.
As such, it looks likely that Starship SN3’s first cryogenic tank proof test – filling the vehicle with inert liquid nitrogen – will coincide with a second dedicated stress test of a Starship thrust structure, hopefully proving itself capable of surviving the force of three Raptor engines at full thrust. While orbital-class Starships will need three more vacuum-optimized Raptor engines, three sea-level engines are all SpaceX needs to begin flight tests with suborbital prototypes.
Based on an unofficial analysis of existing photos, it appears that every single major structural piece of Starship SN3 – excluding legs and fins – is nearing completion, even including the ship’s shiny nosecone. Likely to head to the launch pad for its first tests as soon as the tank section alone has been completed, just one stacking event remains before said tank section reaches its full height. Right now, both of those parts have been moved to a dedicated Vehicle/Vertical Assembly Building (VAB) and are probably no more than a day or two away from being joined*. Perhaps just a day or two after that milestone, SpaceX will likely transport the massive rocket to the launch pad to begin preparing for its first proof tests.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The upgrade follows earlier phases of Tesla’s self-funded shuttle program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
