SpaceX has finished its third full-scale Starship prototype and rolled the rocket’s tank and engine section to a nearby launch pad just a matter of weeks after work began, now ready to prepare for a potentially imminent Starhopper-style hop test.

SpaceX’s rapidly-growing Boca Chica, Texas Starship factory is now producing so much rocket hardware that it’s hard to track any single vehicle’s birth. However, it still appears that SpaceX’s Texas team managed to complete the Starship SN3 prototype in less than a month, measured from first steel ring stacking to the ship’s integrated business end being transported to the launch pad. Simultaneously, the company fabricated, assembled, and tested an entirely separate Starship test tank, verifying that a design flaw that likely lead to Starship SN1’s February 28th destruction had been rectified.

Featuring the same design improvements that allowed that Starship test tank to become the first to pass proof testing intact, Starship SN3 is the best candidate yet to kick off true wet dress rehearsal (WDR) and Raptor engine static fire testing. Both will require real liquid methane and oxygen propellant to be loaded, potentially turning Starship SN3 into the equivalent of many tons of TNT if things were to go south. To be clear, there is a significant chance that such an early, rapidly-built prototype will not survive its upcoming test campaign. Nevertheless, Starship SN3 has the numerous lessons learned from both the successes and failures of all previous vehicles built into it, giving it the best chance yet. Still, the massive rocket will need to pass one or several less risky tests before it can begin to attempt more groundbreaking feats.

Set to follow in the footsteps of all previous Starship test articles, SpaceX will soon kick off Starship SN3’s test campaign with a liquid nitrogen proof test – still extremely cold (i.e. cryogenic) but chemically neutral (i.e. can’t explode). Delivery trucks were spotted topping off SpaceX’s liquid nitrogen supplies just yesterday. The company also has a four-hour road closure scheduled to start at 5pm CDT (22:00 UTC) today, shortly after this article went live.

If it isn’t delayed, that March 29th road closure is likely meant to allow SpaceX to pressurize Starship SN3 with liquid nitrogen, pushing it beyond flight pressures (6 bar/90 psi) in what’s known as a proof test. If successful, it would verify that the rocket’s tank section is sound while also bringing it to cryogenic temperatures, potentially strengthening the steel with cryogenic hardening.

Just hours later, SpaceX technicians lifted the Starship tank section onto the launch mount, where it will be prepared for imminent proof testing. (SPadre)

Beyond those initial plans, the FAA license SpaceX used to support Starhopper’s July and August 2019 hop tests may actually enable test flights of full-scale Starship prototypes, too. Incredibly, according to Cameron County, Texas beach closure requests made on March 23rd, SpaceX’s goal is to prepare Starship SN3 for a Raptor engine static fire test as early as April 1st (no fool), followed by a potential 150m (500 ft) Starhopper-style flight test on April 6th.

For obvious reasons, delays to that ambitious schedule – particularly the flight test – are extremely likely, but Starship SN3 is now unequivocally at the launch pad. Stay tuned for updates on the rocket’s potentially imminent proof test and the impacts that might have on future tests.

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 announces 100k Powerwalls are participating in Virtual Power Plants

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.

Elon Musk teases Tesla Roadster unveiling once again

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.

A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”

Musk agreed:

The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.

It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:

“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”

The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.

However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.

For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”

We sure hope.
