A SpaceX Starship rocket could take to the sky for the first time later this week
SpaceX has scrubbed its latest Starship static fire test for the third time since Friday but if another attempt succeeds within the next few days, a full-scale Starship prototype could lift off for the first time later this week.
SpaceX has attempted to perform a Starship static fire every day for the last three days without any luck, foiled by what must be mild technical issues and some extreme South Texas weather. That static fire – set to be Starship serial number 4’s (SN4) third – is required because SpaceX chose to replace the rocket’s installed Raptor engine (SN18) around 10 days ago after completing two successful tests on May 4th and 5th. Installed a few days after SN18 was removed, Starship and Raptor SN20 must now perform their own integrated static fire to ensure the complex systems are working properly.
Since SN4’s last test, SpaceX teams have been swarming the Starship prototype day and night, installing new COPVs (composite overwrapped pressure vessels; used to store high-pressure gas), new plumbing, and more. The specific purposes of all those in-situ changes can only be speculated at but what is clear is that SpaceX is preparing Starship SN4 for the first attempted flight test of a full-scale prototype, following in the footsteps of Starhopper’s bizarre but successful July and August 2019 hops. As SN4’s third Raptor static fire has slipped, though, so has that flight test. While the FAA has yet to officially publish a license for the 150m (~500 ft) Starship hop, NOTAMs (Notices to Airmen) filed recently suggest that that license and hop could come any day now.
Most recently, a NOTAM was filed on May 18th for what is likely Starship’s 150m hop test on Thursday, May 21st. Filed before SN4’s May 18th static fire test was aborted twice, that proposed May 21st hop test will almost certainly be delayed at least as long as the static fire that needs to precede it and is also dependent upon the FAA officially licensing the flight. The fact that NOTAMs are being filed for that flight strongly suggests that SpaceX and the FAA or in the late stages of hammering out a license, a process that can often involve a great deal of back-and-forth and compromise for experimental rocket launches.
Regardless, if or when Starship SN4 finally manages to fire up its new Raptor engine, it could be just a matter of days after that SpaceX attempts the first true Starship flight test. If everything goes according to plan, the ~30m (~100 ft) tall stainless steel rocket will lift off under the power of a single asymmetrically installed Raptor engine, capable of producing up to 200 metric tons (~450,000 lbf) of thrust with cryogenic liquid methane and oxygen propellant.
After lifting off from its ad-hoc South Texas launch mount, Starship SN4 will attempt to reach a peak altitude of 150m (~500 ft) and descend back down for a soft landing on an adjacent concrete pad, just like Starhopper did around nine months ago. A lot could go wrong: aside from using steel more than three times thinner than Starhopper’s, Starship SN4 will also be debuting an entirely new kind of landing leg, will be flying with asymmetric thrust, and will likely be using autogenous pressurization — all new challenges for SpaceX.
Nevertheless, there are also reasons for confidence. SpaceX has already successfully pressurized Starship SN4 all the way to 7.5 bar (~110 psi, sufficient for uncrewed orbital flight), performed multiple wet dress rehearsals and two Raptor static fire tests, and even tested what appears to be a new kind of cold gas thruster needed for roll control. Most importantly, even if Starship SN4 is destroyed during its next static fire or inaugural flight attempt, Starship SN5 is nearly at the same stage of completion and should be ready to take the reins almost immediately after the potential demise of its predecessor. With Crew Dragon’s inaugural NASA astronaut launch scheduled on May 27th, the rest of the month is set to be quite the event.

Tesla AI5 chip nears completion, Elon Musk teases 9-month development cadence
The Tesla CEO shared his recent insights in a post on social media platform X.
Tesla’s next-generation AI5 chip is nearly complete, and work on its successor is already underway, as per a recent update from Elon Musk.
The Tesla CEO shared his recent insights in a post on social media platform X.
Musk details AI chip roadmap
In his post, Elon Musk stated that Tesla’s AI5 chip design is “almost done,” while AI6 has already entered early development. Musk added that Tesla plans to continue iterating rapidly, with AI7, AI8, AI9, and future generations targeting a nine-month design cycle.
He also noted that Tesla’s in-house chips could become the highest-volume AI processors in the world. Musk framed his update as a recruiting message, encouraging engineers to join Tesla’s AI and chip development teams.
Tesla community member Herbert Ong highlighted the strategic importance of the timeline, noting that faster chip cycles enable quicker learning, faster iteration, and a compounding advantage in AI and autonomy that becomes increasingly difficult for competitors to close.
AI5 manufacturing takes shape
Musk’s comments align with earlier reporting on AI5’s production plans. In December, it was reported that Samsung is preparing to manufacture Tesla’s AI5 chip, accelerating hiring for experienced engineers to support U.S. production and address complex foundry challenges.
Samsung is one of two suppliers selected for AI5, alongside TSMC. The companies are expected to produce different versions of the AI5 chip, with TSMC reportedly using a 3nm process and Samsung using a 2nm process.
Musk has previously stated that while different foundries translate chip designs into physical silicon in different ways, the goal is for both versions of the Tesla AI5 chip to operate identically. AI5 will succeed Tesla’s current AI4 hardware, formerly known as Hardware 4, and is expected to support the company’s Full Self-Driving system as well as other AI-driven efforts, including Optimus.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.
This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
