SpaceX Starship rocket catches fire during third Raptor engine test
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.

Tesla is nearing its long-awaited unveiling of the all-electric Tesla Roadster, a new report from The Information claims, as the company has said several times this year that the event would take place “soon.”
Now, it appears there is movement on Tesla’s end regarding when it will happen.
The report says that Tesla will unveil the Roadster as soon as this month with a SpaceX version that will utilize cold-gas thrusters to help the vehicle float for a short period of time. This is something CEO Elon Musk has talked about with the Roadster for years.

Additionally, due to the delays, Tesla explored “a variety of designs” for the Roadster, potentially planning to abandon the design it showed off for the first time in 2017 and adopting an entirely new aesthetic.
According to The Information, Tesla considered utilizing a repurposed Model S Plaid and even wanted to upgrade the look to something like a Lamborghini Countach.
We’ve heard all of these things before, including teases about the date and how “soon” the Roadster will finally be ready to be shown off to the world (for the second time). Musk said that the event would occur in April, then May, then Chief Designer Franz von Holzhausen continued to say it would be coming “soon.”
We do expect to see the Roadster by the end of the year, and now with this new report swirling, it appears it could be sooner rather than later.
The wait has been incredibly long, but there is likely a good reason for it. Tesla’s desire to make the Roadster the craziest vehicle on the road was non-negotiable, and it likely took a lot of time and resources to develop and perfect into something that was safe and suitable for a vehicle like this.

Tesla finally got its Nevada Robotaxi Permit but with a few catches hard to miss
Nevada granted Tesla’s robotaxi permit, but capped the fleet at just ten vehicles for now.
Tesla has received its robotaxi permit in Nevada, more than two months after regulators closed the public comment period on the company’s application. News of the approval surfaced Wednesday night when Tesla investor and longtime company watcher Sawyer Merritt posted a copy of the interim order, and the Nevada Transportation Authority’s own carrier registry now lists the permit, AVNC Permit 002 under Docket 26-05015, as active for Tesla Robotaxi, LLC.
Tesla asked Nevada in June for authority to run up to 5,000 vehicles in Clark County within a year, however the permit the NTA issued is initially capping Tesla at ten fully autonomous vehicles and confines them to a defined geofence along the Las Vegas Strip corridor. Any expansion of that operating area, or any increase to the fleet size, requires the NTA’s approval first.

The order also sets rules that look more restrictive than what Tesla runs in Austin. Rides are barred on roads with posted speed limits above 45 miles per hour, pickups are off limits within a quarter mile of Harry Reid International Airport without separate authorization, and every vehicle has to carry visible “Robotaxi” markings while notifying riders before each trip that no one is driving. The order also requires “appropriate human supervision”, language that suggests Nevada isn’t ready to let Tesla offer the rides without a safety monitor that it has run in parts of Austin since January. As with standard protocol with robotaxi services, Tesla must report any accident, system failure, or vehicle that becomes stranded on a Nevada road within five business days.
Tesla is entering a market Nevada already knows well. Zoox, the Amazon owned robotaxi company, has run its own autonomous vehicle permit in the state since last year, building up to roughly 100 vehicles and 350,000 rides along the Strip. That history likely explains why the NTA started Tesla at ten cars rather than the fleet size the company asked for. The agency has a template for scaling a permit up once a company proves out its safety record.
Tesla’s Nevada application first surfaced in June, when the company filed for the permit alongside plans for a maintenance hub in southwest Las Vegas. The company has said it won’t meaningfully scale its robotaxi fleet anywhere until FSD v15 ships, expected in late 2026 or early 2027, which makes the ten vehicle cap less of a constraint today than it might look on paper. For now, Tesla has the legal right to start Nevada rides. Whether it starts before FSD v15 arrives is a separate question the permit doesn’t answer.
Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.
Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.
