SpaceX stacks orbital Starship sections as Elon Musk teases June 20th event
SpaceX CEO Elon Musk says he will provide a public update on the development status of Starship and Super Heavy in an official presentation later this summer, possibly as soon as June 20th.
Meanwhile, SpaceX’s South Texas team have been busy at work on both Starhopper and a newer Starship, said by Musk to be the first orbit-capable prototype. In the last week, technicians have begun stacking several sections of the vehicle’s stainless steel hull, all fabricated and welded together side-by-side. On Thursday, May 9th, this progressed to the installation of the Starship’s first gently tapered nose section atop its cylindrical tank section. Likely the second- or third-to-last major stack before its aeroshell is assembled into one piece, the orbital prototype is starting to truly resemble a real Starship.
They grow up so fast…
CEO Elon Musk revealed SpaceX’s Mars colonization architecture back in September 2016 and has since provided design and development updates every 6-12 months. Between then now, Starship/Super Heavy (formerly BFR, fore-formerly ITS) has radically changed. Originally baselined with a diameter of 12 m (40 ft), an almost entirely carbon composite design, and a spaceship with bulky tripod fins/wings, SpaceX helped design, build, and test a full-scale liquid oxygen tank.
Six months after the tank was destroyed (likely intentionally) during testing, Musk announced in Sept. 2017 that ITS was now called BFR and would feature a leaner 9m (30 ft) diameter. He also revealed tentative plans to enlist BFR in a point-to-point Earth transportation scheme offering travelers access to almost anywhere on Earth in ~30 minutes. In September 2018, the design changed once more, gaining ~10m of height and three mobile tripod fins/wings/legs. Finally, just a few months after the 2018 update, Musk revealed that SpaceX was moving almost entirely away from carbon composites and would instead use stainless steel throughout BFR’s structure. BFR was also renamed to Starship/Super Heavy.
Episode 4: Revenge of the Steel
Given SpaceX’s breakneck pace of Starhopper and Starship development, it’s possible that Musk’s “probably June 20th” event is meant to correlate with a yet-unknown Starship or Starhopper milestone. Back in early January, Musk suggested that the first orbital Starship prototype could be “complete” as early as June. However, a few weeks later, Starhopper suffered a setback when its facade/nosecone toppled over and was irreparably destroyed.
Several months distant, it’s hard to actually say if that hardware loss has impacted SpaceX’s schedule much at all. Sans nose section, SpaceX instead conducted a number of wet dress rehearsals and successfully ignited Raptor and jumped the tethered Starhopper a few feet in early April, more or less right on schedule per a December 2018 Musk tweet.
At this point in time, it’s highly unlikely that the orbital Starship prototype will be truly complete just a month or two from now. Most notably, “completion” would require seven flight-ready Raptor engines, of which SpaceX is known to have only completed 3-4 in the last four months. Despite an apparent lack of Raptors for a June completion of the orbital prototype, it may actually be possible for SpaceX to complete (in a very rough sense) the main structure of the Starship.
Major progress has been made in the last few weeks and the orbital prototype is starting to look more and more like an actual Starship. Aside from finishing the vehicle’s propellant and header tanks and engine section/thrust structure, SpaceX still needs to install avionics, wiring, plumbing, cold-gas maneuvering thrusters, COPVs, access and umbilical ports and panels, an entire heat shield, its tripod wings/fins/legs, and more. At the same time, it’s unclear if SpaceX will attempt to send Starship to orbit on its own before the first Super Heavy booster prototype is complete, an even more massive undertaking ahead of the company.
For now, all we can do is wait and watch SpaceX’s gloriously bizarre steel Starship prototype continue to grow, while Starhoppper prepares for untethered hops a few thousand feet to the east. Things could be worse!

Elon Musk makes a key Tesla Optimus detail official
“Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote on X.
Tesla CEO Elon Musk just made a key detail about Optimus official. In a post on X, the CEO clarified some key wording about Optimus, which should help the media and the public become more familiar with the humanoid robot.
Elon Musk makes Optimus’ plural term official
Elon Musk posted a number of Optimus-related posts on X this weekend. On Saturday, he stated that Optimus would be the Von Neumann probe, a machine that could eventually be capable of replicating itself. This capability, it seems, would be the key to Tesla achieving Elon Musk’s ambitious Optimus production targets.
Amidst the conversations about Optimus on X, a user of the social media platform asked the CEO what the plural term for the humanoid robot will be. As per Musk, Tesla will be setting the plural term for Optimus since the company also decided on the robot’s singular term. “Since we are naming the singular, we will also name the plural, so Optimi it is,” Musk wrote in his reply on X.
This makes it official. For media outlets such as Teslarati, numerous Optimus bots are now called Optimi. It rolls off the tongue pretty well, too.
Optimi will be a common sight worldwide
While Musk’s comment may seem pretty mundane to some, it is actually very important. Optimus is intended to be Tesla’s highest volume product, with the CEO estimating that the humanoid robot could eventually see annual production rates in the hundreds of millions, perhaps even more. Since Optimi will be a very common sight worldwide, it is good that people can now get used to terms describing the humanoid robot.
-->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-Optimi-per-year production line at the Fremont Factory. Giga Texas would get an even bigger Optimus production line, which should be capable of producing tens of millions of Optimi per year.

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 update follows earlier phases of Tesla’s “Giga Train” 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.
