SpaceX Starship Mk1’s most important tests yet could begin just hours from now
SpaceX’s South Texas Starship Mk1 prototype is on the verge of kicking off a critical period of ground tests, ranging from tank pressurization and propellant loading to the rocket’s first triple-Raptor engine static fire. The campaign could begin soon – perhaps as soon as later today, in fact.
Over the last two weeks, SpaceX’s South Texas team has faced bad winter weather, among the many other challenges associated with building giant rockets almost entirely out in the elements. Nevertheless, company technicians and engineers continue to check off task after task along the path towards Starship Mk1 completion, the next-generation launch vehicle’s first full-scale, high-fidelity prototype.
In the month of November alone, SpaceX has (re)installed Starship Mk1’s nose and aft section flaps (this time outfitted with heavy-duty actuator mechanisms), nearly completed the process of routing and integrating the vehicle’s external liquid and gas plumbing, and more or less finished a barebones launch mount. Starship Mk1 was snugly attached atop that launch mount around the start of the month and workers have continuously swarmed around the rocket and pad in scissor and boom lifts and ever since, closing out umbilical connections, insulating cryogenic propellant pipes, and much, much more.
Within the last week or so, SpaceX has apparently also begun the process of expanding its presence around its existing Boca Chica pad facilities, where Starship Mk1 is preparing for testing. The purpose of that expansion is unclear, but the first phase – extending the existing square landing pad – is essentially complete and will presumably give Starship Mk1 a better chance of successfully landing in the event that its first skydiver-style landing attempt is not as accurate as predicted.
Based on official renders/mockups in SpaceX’s updated 2019 launch animation, it could also eventually become the foundation of a much more permanent integration and processing hangar, much like the hangars that SpaceX uses to integrate Falcon 9 and Heavy at its Florida and California launch sites. It could even be the foundation for a dramatically larger Super Heavy-class launch mount and water-cooled flame deflector like the one shown in that same video. For now, Starship Mk1 will begin testing (and presumably first flights) off of a minimal steel mount that was built up from almost nothing in barely two months.
No nose, no problem?
As previously discussed on Teslarati, the testing Starship Mk1 is preparing for could take a number of routes to completion, but all of those routes will likely involve several main events. First, SpaceX may or may not decide to do a preliminary tank proof test with neutral (i.e. non-explosive) liquid nitrogen, which would verify the structural integrity and determine if there are leaks in what is essentially a building-sized pressure vessel.
SpaceX may instead skip that – it would require a vast and unwieldy quantity of liquid nitrogen – and move directly into the first cryogenic propellant loading test, in which SpaceX would attempt to fully fill Starship’s tanks with liquid oxygen and liquid methane. Assuming Starship Mk1 is 1:1 scale, that could involve as much as 1200 metric tons (2,650,000 lbs) of propellant, more than twice as much fuel as a Falcon 9.
In other words, Starship’s inaugural propellant loading attempt will be almost at the same scale as Falcon Heavy’s, which took several attempts, broke some hardware, and was a major learning experience and challenge on its own. A structural failure or explosion could be absolutely catastrophic, as those ~1200 tons of fuel and oxidizer could act as a massive bomb under the right conditions.
According to road closure notices published by Cameron County, SpaceX is expected to begin operations that require road closures as early as November 18th from noon to 8 pm CST, with backups on the 19th and 20th. Another window opens on the 25th at the same time, with backups on the 26th and 27th. To be clear, there is no official word that SpaceX actually means to start cryogenic ground testing with Starship Mk1 today, but it’s not necessarily out of the question.
Whenever SpaceX does decide to start Starship Mk1 ground testing, it will be an immensely important milestone, signifying the start of the period that will essentially determine whether SpaceX’s deeply unusual manufacturing methods can build a structurally-sound, high-performance rocket prototype for pennies on the dollar. In simple terms, if Starship Mk1 behaves as planned, commercial spaceflight may never be the same.

SpaceX has decided to stand down from what was supposed to be the first test launch of Starship’s v3 rocket tonight after a minor issue with a hydraulic pin delayed the flight once more.
The company scrubbed its first test flight of the upgraded Starship v3 on May 21 in the final minutes of the countdown. SpaceX CEO Elon Musk quickly took to social media platform X, explaining that a hydraulic pin on the launch tower’s “chopsticks” arm failed to retract properly.
Musk added that the company would fix the issue this evening. SpaceX will attempt another launch tomorrow night at 5:30 p.m. CT, 6:30 p.m. ET, and 3:30 p.m. PT.
The hydraulic pin holding the tower arm in place did not retract.
If that can be fixed tonight, there will be another launch attempt tomorrow at 5:30 CT. https://t.co/DJAdvDYQpH

The countdown for Starship Flight 12 — featuring the taller and more capable V3 stack with Booster 19 and Ship 39 — had been progressing smoothly until the late-stage issue surfaced. The Mechazilla tower arm, designed to secure the vehicle on the pad and eventually catch returning boosters, could not complete its retraction sequence.
SpaceX teams immediately began troubleshooting the hydraulic system for an overnight repair.
Starship V3 introduces several significant upgrades over earlier versions. These include greater propellant capacity, more powerful Raptor 3 engines, larger grid fins, enhanced heat shielding, and an improved fuel transfer system.
We covered the changes that were announced just days ago by SpaceX:
SpaceX unveils sweeping Starship V3 upgrades ahead of May 19 launch
The changes are intended to increase payload performance, support higher flight rates, and advance the vehicle toward operational missions, including Starlink deployments, NASA Artemis lunar landings, and future crewed Mars flights. The debut flight from Starbase’s new Launch Pad 2 marked an important milestone in scaling up the fully reusable Starship system.
This stand-down highlights the intricate challenges of preparing the world’s most powerful rocket for flight. Despite extensive pre-launch checks, a single component in the ground support equipment can force a scrub.
The incident aligns with Starship’s proven iterative development approach. Previous test flights have encountered both successes and setbacks, each providing critical data that refines hardware and procedures. Some outlets may call some of these flights “failures,” when in reality, they are all opportunities for SpaceX to learn for the next attempt.
With V3, SpaceX aims to reduce ground-system dependencies and increase launch cadence to meet ambitious long-term goals.
The Tesla Model Y became the first-ever car to reach a legendary Norwegian milestone, surpassing 100,000 new registrations after gaining a reputation as one of the most popular vehicles in the country and the world.
As of May 20, Norwegian authorities have registered 100,224 units of the electric SUV, according to data from local outlet Opplysningsrådet for veitrafikken (OFV).
By population, roughly one in every 29 passenger cars on Norwegian roads is now a Model Y, underscoring its rapid rise as a national favorite.
Since the first deliveries in August 2021, the Model Y has transformed from a newcomer to a staple in Norwegian traffic.
Tesla back on top as Norway’s EV market surges to 98% share in February
Geir Inge Stokke, the Managing Director of OFV, described the achievement as “remarkable,” noting that few single models have gained such traction so quickly. “Tesla Model Y has hit the Norwegian market spot on, and the numbers illustrate how fast the EV market has developed here,” Stokke said.
The Model Y’s success reflects Norway’s aggressive push toward electrification. Nearly nine out of ten units, 87.6 percent, to be exact, are privately registered, with the remaining 12.4 percent on company plates. Owners span the country, from major cities to smaller municipalities, proving it is no longer just an urban or niche vehicle but a true “people’s car.
Who is Buying Tesla Model Ys in Norway?
Typical Model Y drivers are men in their early 40s. The average registered user age is 44, with 83 percent male and 17 percent female. Stokke noted that household usage often extends beyond the primary registrant, broadening the vehicle’s real-world appeal.
Geographically, adoption concentrates in urban centers with strong charging infrastructure. Oslo leads with 16,861 registrations (16.82 percent of the national total), followed by Bergen (7,450), Bærum (4,313), and Trondheim (4,240).
The top five municipalities—Oslo, Bergen, Bærum, Trondheim, and Asker—account for 35,463 units, or about 35 percent of all Model Ys. Yet the vehicle’s presence outside big cities highlights its broad acceptance.
Growth Trajectory and Popularity
Tesla built a lot of sales momentum in a short amount of time. In 2021, registrations closed out at 8,267, but more than doubled to more than 17,000 units in 2022 and more than 23,000 units in 2023. 2025 was the company’s strongest year yet, as Tesla managed to record 27,621 registrations.
Through 2026, Tesla already has 7,036 registrations.
Tesla’s Global Success with the Model Y
Tesla has tasted so much success with the Model Y; it has been the best-selling car in the world three times, it has dominated EV sales in numerous countries, and contributed to a mass adoption of electric vehicles across the planet.
As Stokke emphasized, the Model Y’s journey from newcomer to icon mirrors Norway’s broader success story. With robust incentives that push sales, excellent infrastructure, and consumer eagerness to transition to sustainable powertrains, the country continues setting global benchmarks in sustainable mobility.
The Tesla Model Y stands as a shining example of how quickly change can happen when conditions align.
