SpaceX’s Starship rocket is a step closer to flight after the fourth full-scale prototype successfully fired up its high-performance Raptor engine for the first time and survived the ordeal.

By far the biggest technical milestone SpaceX’s Starship program has passed since its creation, the Starship serial number 4 (SN4) prototype’s May 5th static fire was just the latest in a series of rapid-fire tests completed over the last several days. The ship’s journey began back in late March when SpaceX technicians began integrating the first sections of its steel hull. Less than a month later, SpaceX officially completed Starship SN4’s tank and engine section – missing only a nosecone and header tanks – and rolled the rocket to the launch and test pad on April 23rd.

Barely two days later, Starship SN4 entered the testing phase, passing what CEO Elon Musk described as an “ambient pressure test” used to verify the structural integrity of the rocket’s propellant tanks with harmless nitrogen gas. Less than a day after that pressure test was completed, SpaceX kicked off a “cryogenic proof test” with the Starship – the same test that destroyed three full-scale prototypes in the five months prior.

In the early morning of April 26th, Starship SN4 thus became the first full-scale prototype to pass (and survive) a cryogenic proof test, in which the ship’s normal liquid oxygen and methane was replaced with similarly frigid but non-explosive liquid nitrogen. According to Musk, SN4 was only pressurized to 4.9 bar (~70 psi), quite a distance away from the ~8.5 bar needed for safe orbital flight but reportedly more than enough to perform a small flight test.

Of course, Starship SN4 would first have to complete a bevy of additional tests – all arguably riskier than the cryogenic proof test it was the first to pass. That second, more challenging phase of testing began six days later on May 2nd.

After some limited fueling effectively marking Starship SN4’s first partial wet dress rehearsal (WDR), SpaceX aborted the first test attempt on May 2nd. On May 3rd, Starship SN4 was successfully loaded with propellant once more and wound up performing what is known as a spin prime test with its lone Raptor engine. Over the course of a few hours, SpaceX then recycled (and rechilled) the ship’s methane propellant and successfully performed a preburner test, igniting two gas generators that spin up Raptor’s turbines and eventually mix in the combustion chamber.

Less than 24 hours later, SpaceX turned Starship SN4 around for the grand finale – an actual Raptor ignition test, also known as a static fire. Per NASASpaceflight’s unofficial livestream of the event, made possible thanks to local resident BocaChicaGal, Starship ignited its Raptor engine – a historic first for the launch vehicle program – at 8:57pm CDT on May 5th (01:57 UTC, May 6). Musk confirmed just a few hours after that the ignition test – lasting about 3 seconds – had been completed successfully.

With that crucial milestone now behind it, Starship SN4 – perhaps pending an additional test or two – should effectively be clear to begin preparations for a 150m (500 ft) hop test later this month. Almost entirely contingent upon receiving a Federal Aviation Administration (FAA) launch license, that process could be finished tomorrow or take several days – or even weeks – to complete. Starship already has landing legs installed and wont need a nosecone for such a short and slow hop, but SpaceX may also need to install some kind of attitude control system (likely gas thrusters) before SN4 can safely fly.

Stay tuned for updates as we learn more about when a full-scale SpaceX Starship is scheduled to fly for the first time.

The Tesla Model Y has become the most common car on Norwegian roads. This is a remarkable achievement for the all-electric crossover, which has also commanded the top spot in Norway’s vehicle sales rankings for several years running.

Model Y Domination

As per vehicle registration figures tracked by the Norwegian Road Traffic Information Council (OFV), there were 68,378 Model Ys with Norwegian license plates at the end of March/beginning of April 2025. In recent weeks, the Model Y passed more than 70,000 registrations, as per a report from Elbil24.

With the Model Y now becoming the most common car in Norway, the Toyota Rav4 now stands in second place, followed by the Nissan Leaf, the Volkswagen Golf, and the Toyota Yaris. The Model Y also topped the country’s vehicle registration rankings for the last three years, and it set a record for selling the most vehicles in a year in 2023, breaking the Volkswagen Beetle’s record that has stood since 1969.

Possibly More Momentum

It is undeniable that the Tesla Model Y has helped Norway push its electric vehicle transition. As of date, electric vehicles now account for 28% of the Norwegian car fleet, a notable portion of which is comprised of the all-electric crossover.

While the Model Y’s achievements in Norway have been impressive, the vehicle could expand its reach into the country even more this year. Tesla, after all, has been aggressively pushing the new Model Y to consumers, with the company offering a zero percent interest promotion for the vehicle. These efforts, as well as the new Model Y’s improved features, should make the vehicle even more compelling to Norwegian car buyers this year.

Tesla Board Chair slams Wall Street Journal over alleged CEO search report

Denholm’s comments were posted by Tesla on its official account on social media platform X.

Tesla Board Chair Robyn Denholm has issued a stern correction to The Wall Street Journal after the publication posted a report alleging that the electric vehicle maker’s Board of Directors opened a search for a new CEO to replace Elon Musk.

Denholm’s comments were posted by Tesla on its official account on social media platform X. 

The WSJ’s Allegations

Citing people reportedly familiar with the discussions, the WSJ alleged that Tesla Board members reached out to several executive search firms to work on a formal process for finding Elon Musk’s successor. The publication also alleged that tensions had been mounting at Tesla due to the company’s dropping sales and profits, as well as the time Musk has been spending with DOGE.

The publication also alleged that Elon Musk had met with the Tesla Board about the matter, and that members told the CEO that he needed to spend more time on Tesla. Musk was reportedly instructed to state his intentions publicly as well. The CEO did not push back against the Board, the WSJ claimed. 

Elon Musk did announce that he is stepping back from his day-to-day role at the Department of Government Efficiency during the Tesla Q1 2025 earnings call. Musk’s announcement was embraced by Tesla investors and analysts, many of whom felt that the CEO’s renewed focus on the EV maker could push the company to greater heights.

Tesla and Musk’s Response

In response to The Wall Street Journal’s report, Tesla’s official account on X shared a comment from its Board Chair. In her comment, Denham noted that the WSJ‘s report was “absolutely false.” She also highlighted that Tesla had communicated this fact to the publication before the report was published, but the Journal ran the story anyway.

“Earlier today, there was a media report erroneously claiming that the Tesla Board had contacted recruitment firms to initiate a CEO search at the company. This is absolutely false (and this was communicated to the media before the report was published). The CEO of Tesla is Elon Musk and the Board is highly confident in his ability to continue executing on the exciting growth plan ahead,” Denholm stated.

Elon Musk himself commented on the matter, stating that the publication showed an “extremely bad breach of ethics” since the report did not even include the Tesla Board of Directors’ denial of the allegations. “It is an EXTREMELY BAD BREACH OF ETHICS that the WSJ would publish a DELIBERATELY FALSE ARTICLE and fail to include an unequivocal denial beforehand by the Tesla board of directors!” Musk wrote in a post on X.

In a conversation with the New York Post, White House Chief of Staff Susie Wiles stated that Tesla and SpaceX CEO Elon Musk is no longer working from the West Wing.

As per the Chief of Staff, Musk is still working for DOGE—as a remote worker, at least.

Remote Musk

In her conversation with the publication, Wiles stated that she still talks with Musk. And while the CEO is now working remotely, his contributions still have the same net effect. 

“Instead of meeting with him in person, I’m talking to him on the phone, but it’s the same net effect,” Wiles stated, adding that “it really doesn’t matter much” that the CEO “hasn’t been here physically.” She also noted that Musk’s team will not be leaving.

“He’s not out of it altogether. He’s just not physically present as much as he was. The people that are doing this work are here doing good things and paying attention to the details. He’ll be stepping back a little, but he’s certainly not abandoning it. And his people are definitely not,” Wiles stated.

Back to Tesla

Musk has been a frequent presence in the White House during the Trump administration’s first 100 days in office. But during the Q1 2025 Tesla earnings call, Musk stated that he would be spending substantially less time with DOGE and substantially more time with Tesla. Musk did emphasize, however, that DOGE’s work is extremely valuable and critical.

“I think I’ll continue to spend a day or two per week on government matters for as long as the President would like me to do so and as long as it is useful. But starting next month, I’ll be allocating probably more of my time to Tesla and now that the major work of establishing the Department of Government Efficiency is done,” Musk stated.
