SpaceX’s Elon Musk: odds of Starship reaching orbit by 2020 are “rising rapidly”
SpaceX CEO Elon Musk has suggested that the company’s newly revamped Starship and Super Heavy rocket (previously known as BFR) could perform its first integrated launches – placing Starship into orbit – as few as 12-24 months from today.
Musk indicated that the odds of Starship reaching orbit as early as 2020 are now as high as “60% [and] rising rapidly”, thanks in no small part to the flurry of radical changes the spacecraft and booster have both undergone over the course of 2018.
Probability at 60% & rising rapidly due to new architecture

Combined with a decision – made public at a September 2018 media event – to delay the debut of a vacuum-optimized upper stage Raptor (RVac) and stick with its mature sea level variant, Musk apparently is quite confident that these dramatic shifts in strategy will allow SpaceX to aggressively slash the development schedules of its next-gen launch vehicle. Intriguingly, Musk noted that while these “radical” design changes were almost entirely motivated by his desire to expedite the fully-reusable rocket’s operational debut, it apparently became clear that the cheaper, faster, and easier iteration could actually end up being (in Musk’s own words) “dramatically better” than its exotic carbon-composite progenitor.
Time. Although it also turned out to be dramatically better.

“Delightfully counter-intuitive”
Let there be little doubt – I am still immensely skeptical of this radical redesign and the implausible logistics of conducting said redesign at the last second while somehow maintaining the test schedule, let alone expediting it by 6-9 months. Despite the fact that Musk does seem to have a compellingly rational answer to every question thus far asked, he was no less convincing in mid-2016 when he stated with contagious conviction that Tesla’s Fremont factory would be an almost 100%-automated “alien dreadnought” as early as 2018. There is, of course, nothing wrong per se with being wrong, although taking 24 months and several hundred million dollars to realize as much can be downright fatal or at least a major health risk for any given company that faces such a challenge, as was the case with Tesla.
Skepticism aside, there are equally many reasons to be optimistic about the future of SpaceX’s Starship/Super Heavy (BFR) program over the next several years. Not only do metal hot structures have a proven track record of success (admittedly in the 1960s and for suborbital conditions, but still), but the century and a half humans have been making and building with steel serves to aggressively reduce risk in BFR’s development, whereas a giant, highly-reusable spaceship and rocket built mainly out of carbon composites is about as exotic, challenging, and alien as one could muster. One step further, Musk appears to be dead-set on the trade that the benefits of moving from composite to stainless steel far, far outweigh the costs.

Most notably, Musk’s implication that a steel alloy skin – albeit with regenerative (i.e. liquid) cooling – could genuinely stand in for SpaceX’s ablative PICA-X heat shield technology on Starship was the most unintuitive but logical shift yet. Although steel alloys may literally have densities that are significantly higher than carbon composites, composites simply cannot (at least in the current state of the art) withstand high temperatures like those that Starship would inevitably experience during orbital and interplanetary reentries. As a result, Starship would need an extremely advanced heat shield technology that is minimally ablative, extremely lightweight, robust, and shock-resistant, not to mention an additional layer capable of mounting it to Starship’s composite hull while also insulating the propellant tanks and structure from the extreme heat of reentry.

Steel, on the other hand, is one of the least thermally conductive metals available, while also featuring alloys with melting points that can approach and even surpass 1500 degrees C. With regenerative cooling, it’s entirely possible that a hot steel shield and fusion of propellant tanks and load-bearing structures could ultimately result in a spaceship far more reusable, reliable, and perhaps even performant that a spaceship relying on exotic heat shield materials and linerless carbon composite propellant tanks.
Perhaps BFR Block 2 or 3 will make room for dramatically improved composite formulations and production methods down the road, but advanced steel and other metal alloys appear to be the way forward for SpaceX for the time being. For now, we can sit, watch, and wait as something comes together at the company’s South Texas test and launch facilities.

Tesla China roars back with highest vehicle registrations this Q2 so far
Tesla China’s 80% week-over-week growth was the most notable among Chinese EV brands.

Tesla China saw a notable rise in new vehicle registrations in the week of June 9 to 15, 2025. During the week, Tesla China’s registrations saw an impressive 80% week-over-week increase, resulting in the electric vehicle maker posting its highest insurance registration figures this Q2 so far.
Tesla China Roars Back
During the week ending June 15, 2025, Tesla China saw 15,500 insurance registrations. This represents an 80% increase from the previous week’s 8,640 units. This is also the highest number of registrations that Tesla has posted in China for the past ten weeks, as noted in a CNEV Post report.
Tesla watchers have observed that the electric vehicle maker’s 80% week-over-week growth was the most notable among Chinese EV brands. Following Tesla was Xpeng, which saw a 52% week-over-week growth to 6,400 registrations, and Nio, which saw a 9.3% week-over-week increase to 4,700 registrations.
Tesla China does not report its weekly vehicle registration figures, though the company’s overall performance in the Chinese auto market can be inferred through new vehicle registration data. Fortunately, these registrations are closely tracked and reported by industry watchers, as well as automakers like Li Auto.
Tesla Model Y Impact
Industry watchers estimate that Tesla China was able to deliver 11,200 new Model Y units to customers in the week ending June 15. This represents a week-over-week improvement of about 85% from the previous week. This bodes well for the revamped all-electric crossover, as it suggests that demand for the vehicle remains strong.
The new Model Y is Tesla’s highest volume seller. Thus, it would not be a surprise if the company’s numbers this Q2 2025 end up relying on the sales figures of the revamped all-electric crossover. Fortunately, Tesla has two more weeks before the quarter ends, which should be enough to increase its quarterly sales numbers to a notable degree.
Tesla’s domestic sales in China totaled 38,588 units in May, down 30% year-over-year but up 34% percent from April, as per data from the China Passenger Car Association (CPCA). In the same month, Giga Shanghai also exported 23,074 vehicles in May.

SpaceX Ax-4 Mission prepares for ISS with new launch date
SpaceX, Axiom Space, and NASA set new launch date for the Ax-4 mission after addressing ISS & rocket concerns.

SpaceX is preparing for a new launch date for the Ax-4 mission to the International Space Station (ISS).
SpaceX, Axiom Space, and NASA addressed recent technical challenges and announced a new launch date of no earlier than Thursday, June 19, for the Ax-4 mission. The delay from June 12 allowed teams to assess repairs to small leaks in the ISS’s Zvezda service module.
NASA and Roscosmos have been monitoring leaks in the Zvezda module’s aft (back) segment for years. However, stable pressure could also result from air flowing across the hatch seal from the central station. As NASA and its partners adapt launch schedules to ensure station safety, adjustments are routine.
“Following the most recent repair, pressure in the transfer tunnel has been stable,” a source noted, suggesting the leaks may be sealed.
“By changing pressure in the transfer tunnel and monitoring over time, teams are evaluating the condition of the transfer tunnel and the hatch seal between the space station and the back of Zvezda,” the source added.
SpaceX has also resolved a liquid oxygen leak found during post-static fire inspections of the Falcon 9 rocket, completing a wet dress rehearsal to confirm readiness. The Ax-4 mission is Axiom Space’s fourth private astronaut trip to the ISS. It will launch from NASA’s Kennedy Space Center in Florida on a Falcon 9 rocket with a new Crew Dragon capsule.
“This is the first flight for this Dragon capsule, and it’s carrying an international crew—a perfect debut. We’ve upgraded storage, propulsion components, and the seat lash design for improved reliability and reuse,” said William Gerstenmaier, SpaceX’s vice president of build and flight reliability.
The Ax-4 mission crew is led by Peggy Whitson, Axiom Space’s director of human spaceflight and former NASA astronaut. The Ax-4 crew includes ISRO astronaut Shubhanshu Shukla as pilot, alongside mission specialists Sławosz Uznański-Wiśniewski from Poland and Tibor Kapu from Hungary. The international team underscores Axiom’s commitment to global collaboration.
The Ax-4 mission will advance scientific research during its ISS stay, supporting Axiom’s goal of building a commercial space station. As teams finalize preparations, the mission’s updated launch date and technical resolutions position it to strengthen private space exploration’s role in advancing space-based innovation.

Sweden blocks Tesla FSD-style testing in Stockholm
It looks like FSD testing in Sweden would have to wait some time.

Tesla is putting a lot of effort into getting its Full Self Driving (FSD) system approved in territories outside North America. But while China seems to have embraced FSD fully, other countries like Sweden do not seem to be receiving Tesla’s automated driving system very well.
This became quite evident in a document from Stockholm City, which has started making the rounds online.
FSD Testing Rejected
The document, which was initially shared by X user @KRoelandschap, indicated that the Swedish Traffic Department in Stockholm had rejected Tesla’s request to start FSD testing in the city’s streets. Tesla has been demonstrating FSD in several areas across Europe, so it is not surprising that the company is also attempting to test its automated driving system in Sweden.
Unfortunately for Tesla, Sweden might prove to be a tough nut to crack. As per the City of Stockholm:
“The Traffic Office is currently working on updating its approach to automation. At the same time, the city and the office are under heavy pressure from other ongoing innovation tests. Our ambition is to actively participate in and learn from the continued development in the field of automation.
“Based on this, and in combination with the fact that the current test is the first of its kind, which entails certain risks for both infrastructure and third parties, and that it is planned to be carried out throughout the city, the City of Stockholm considers it is currently not possible to approve the implementation of the test.”
Tesla’s Other Swedish Troubles
Sweden’s FSD testing rejection is not the only roadblock facing Tesla in the country. Since October 2023, Swedish unions have been engaged in an active effort to disrupt Tesla’s operations. The unions’ efforts have been varied, with some resulting in Tesla having difficulty launching more Superchargers in Sweden. Despite this, Tesla has remained stubborn and has refused to bow to the unions’ demands.
Fortunately for Tesla, it seems like its numbers are still strong. Despite the company’s decline in several European countries, the new Model Y is starting to see strong sales figures in Sweden. In early May alone, the new Model Y became the country’s most popular electric vehicle—a notable accomplishment considering the unions’ active efforts to disrupt Tesla.
