SpaceX appears to have successfully fired up its fourth full-scale Starship prototype for the third time, although the Raptor engine test ended with the aft end of the ship catching fire and burning for quite some time.

Around May 7th, hours after Starship SN4 completed its second wet dress rehearsal and Raptor static fire in ~24 hours, SpaceX removed the SN18 Raptor engine it had used to support those tests, transporting it back to storage facilities a mile down the road. Three days later, SpaceX sent Raptor SN20 down the same same road and installed it on Starship SN4 – a swap made for unknown reasons.

Regardless, that swap meant that SpaceX would need to perform at least one more static fire test to prove that Starship and its new Raptor engine were getting along before the company could proceed to hop test preparations. After several days of at least 4 aborted Starship static fire attempts, SpaceX has finally managed to fuel Starship SN4 and ignite Raptor engine SN20 – but not before a new challenge cropped up.

Just shy of 1:01 pm CDT (18:01 UTC), Starship SN4 appeared to successfully fire up Raptor SN20 for at least several seconds, serving as an in-situ acceptance test for the advanced rocket engine. Like the Merlin 1D engines that power Falcon 9 boosters, Raptors are built in Hawthorne, California, shipped to McGregor, Texas for standalone acceptance testing, installed on their assigned rocket, and static fired one more time before SpaceX deems them ready for launch.

This static fire thus served to verify that Starship SN4 and Raptor SN20 were both still in good health after a busy week of numerous tests and several weeks or months in storage, respectively. If fully successful, it would likely clear Starship SN4 to attempt what would be the inaugural flight of a full-scale Starship prototype, potentially ready to occur as early as May 21st (pending an FAA license, of course). Unfortunately, when Raptor SN20 ignited, it appeared to shake or overpressurize one or several plumbing lines, catching what must have been a methane vent or drain line on fire.

While the rocket itself is likely totally fine, much like its Starhopper predecessor suffered even worse fires during its summer 2019 test campaign, the dark smoke that appeared shortly after the secondary fire started is not a great sign. As methane and oxygen burn quite cleanly, that smoke likely means that the fire(s) got to some of the extensive wiring covering Starship and connecting to its test stand and ground controllers. If damaged, all of that wiring will need to be replaced, while the leaky methane pipe that burned for a solid 15 minutes will also need to be fixed.

As such, it’s likely that Starship SN4 will need to wait at least several more days – and may even need to complete a fourth static fire test – before SpaceX can clear it for an inaugural 150m (~500 ft) hop test.

Honda and Acura electric vehicles will soon be plugging into Tesla’s Supercharger network, with approved NACS-CCS adapters rolling out to Prologue and ZDX owners in June 2025.

This provides Honda and Acura EVs access to over 20,000 Superchargers across the United States.

Adapters Ensure Safety

Starting June 2025, Honda Prologue and Acura ZDX drivers can acquire a Honda-approved NACS-CCS DC fast-charging adapter at authorized U.S. dealerships, with pricing set closer to launch. Tested for safety and compatibility, it’s the only DC adapter that Honda recommends for its EVs at NACS stations, as noted in a press release

Ryan Harty, assistant vice president of Sustainability & Business Development at American Honda Motor Co., Inc., shared his thoughts on the matter. “Adding Tesla Supercharger network access to the charging networks already available to our EV customers means industry-leading fast-charging access for Honda and Acura EV drivers,” he said.

Tesla requires approved NACS adapters at its Superchargers, and Honda strongly recommends that Prologue and ZDX owners use approved adapters. Honda also noted that damage caused by using unapproved adapters may not be covered by cars’ limited warranties.

Honda’s Big Charging Vision by 2030

Honda’s not stopping at Tesla’s network. By 2030, Prologue and ZDX owners are expected to tap roughly 100,000 DC fast-charge points across North America, blending Tesla Superchargers with IONNA’s new network, EVgo, and Electrify America. 

“By the end of this decade, we strive to provide Honda and Acura EV drivers with the most convenient and easy charging at more than 100,000 charge points nationwide, helping people choose to purchase an EV for the many benefits of driving one,” Harty stated.

“Tesla Takedown” movement plans 500 protests in 277 stores, Superchargers

Rep. Jasmine Crockett (D-TX) stated that March 29 is her birthday, and “all I want to see happen on my birthday is for Elon to be taken down.”

The “Tesla Takedown” group is aiming to hold its “biggest day of action” in over 277 Tesla stores, as well as Supercharger stations.

During a mass call on Wednesday, organizers, filmmakers, members of Congress, and other key individuals banded together to call for a mass demonstration against the electric vehicle maker this coming March 29, as noted in a report from The Verge.

Tesla Takedown

The Tesla Takedown movement emerged from critics’ opposition to Elon Musk’s increasingly political nature, his close relationship with U.S. President Donald Trump, and his work with the Department of Government Efficiency (DOGE), which is aimed at cutting unnecessary government spending and waste. Members of the Tesla Takedown movement have targeted the EV maker since a notable portion of Musk’s net worth is tied to his Tesla holdings.

Unfortunately, protests against the electric vehicle maker and Musk have become increasingly violent, with Tesla stores being shot up and vehicles being burned in acts of arson. Supercharger stations have also been targeted in arson attacks. Tesla owners’ vehicles have been vandalized and set on fire as well.

Amidst these attacks, Trump has noted that he considers such actions as domestic terrorism. Attorney General Pam Bondi has also noted that those behind the arson and vandalism against Teslas will be caught and persecuted.

“No Conspiracy,” but Still Wishing For Musk Takedown

During the hour-long call, actor and filmmaker Alex Winter, who promoted the Tesla Takedown movement on BlueSky, stated that there is no conspiracy to take down the electric vehicle maker. “There is no conspiracy, there is no well-funded cabal. It’s just Elon Musk who has taken Tesla down,” he said.

Alice Hu, executive director of Planet Over Profit, noted that protesters are looking to hold over 500 events across the world on March 29, with 277 Tesla stores expected to see demonstrations. She also stated that protesters should feel free to demonstrate at Supercharger stations. 

“We need to show Elon that he can throw a tantrum online because his stocks are tanking. He can get Trump to put on a humiliating used car show in front of the White House. These wannabe authoritarians can try to intimidate us from exercising our First Amendment rights, but they can’t stop us from fighting back,” Hu said.

Rep. Jasmine Crockett (D-TX) called for participants to fight, though she was quick to state that protests should be nonviolent. “The things that we’re fighting for, we are fighting for our country. We’re fighting for democracy. We’re fighting for our freedoms. And when I say fighting, I’m saying that figuratively. Obviously, everything that I am promoting is nonviolent,” she said. Interestingly enough, Crockett also stated that March 29 is her birthday, and “all I want to see happen on my birthday is for Elon to be taken down.”

Elon Musk confirms two measures Tesla is taking to fight vandalism

Tesla CEO Elon Musk has announced two measures the company is taking to fight the vandalism that is going on at showrooms across the country as vehicles and even structures have been lit on fire, spray painted, or damaged by various means by those who oppose him or the automaker.

As attacks against Tesla owners and even the company directly continue to occur across the country, people have been wondering what the company will do to fight back. After President Trump and other members of the administration stated that attacks against the company would be treated as domestic terrorism, many thought things would cool down.

However, things have only intensified. Although several of the perpetrators have been arrested and are facing consequences, it seems the severity of the attacks has only gotten worse. Things like Molotov cocktails have been employed by protestors to show their distaste for the company.

Now, Musk is detailing several things Tesla is doing at its showrooms in hopes of ending everything that has gone on and persisted due to the resistance from those who oppose the automaker.

Musk says that Tesla is now ramping up security at its showrooms and is now using Sentry Mode on all vehicles to help catch perpetrators in the act.

We have seen security beef up in several high-profile locations, including Tesla’s Las Vegas location on Sahara Blvd., where Las Vegas Metro Police were spotted yesterday keeping things under control:

Additionally, Sentry Mode has already done a great job of catching several perpetrators in the act, like this one who was recently caught, arrested, and now faces up to 18 months in jail for keying a swastika in a Tesla:

Hopefully, these two measures can eliminate most of the issues Tesla has had at its showrooms. If not, there will likely be follow-up measures utilized by Tesla in hopes of ending this senseless vandalism.
