SpaceX Starship holds up under pressure, lines up Raptor engine test fire
After a few false starts and some minor delays, SpaceX’s 11th Starship prototype (SN11) has made it through two of the three major tests standing between it and liftoff.
SpaceX rolled Starship SN11 from the factory to the launch pad on March 8th, just five days after Starship SN10 briefly became the first prototype of its kind to land in one piece. One or two issues with Raptor’s final landing burn caused SN10 to touch down faster than expected and eventually led to the rocket’s explosive demise around 15 minutes later. Still, the test flight was an almost unequivocal success and seemingly left SpaceX with more than enough confidence to speed through preparations for the next flight test.
Heading into the next day, SpaceX had hoped to kick off cryogenic proof testing but Starship SN11 required a bit more attention than expected and unknown bugs ultimately meant that only an ambient-temperature pressure test could be completed by the end of the test window. Those issues appeared to persist through the end of March 10th, preventing any kind of proof test attempt.
On March 11th, Starship SN11 was able to take its first real stab at a cryo proof and was loaded with liquid nitrogen (LN2), a cryogenic fluid with a density and temperature similar to Starship’s liquid oxygen and methane propellant but without the risk of a catastrophic fire or explosion. Over the course of three or so hours, SpaceX didn’t appear to fully load SN11 with LN2, a possible sign of a technical bug that could just as easily be an intentional part of the test design.
Oddly, parts of the evenings testing were unlike past cryo proofs and there’s a slight chance that the activity was actually a static fire attempt scrubbed well before ignition, though it’s impossible to say without official confirmation.
Otherwise, the most notable part of the cryo proof was a test of Starship SN11’s attitude control system (ACS) that involved firing each of the ship’s several cold-gas nitrogen thrusters at least 5-10 times for a total of several dozen bursts. The current generation of Starships mainly use those thrusters to augment their flaps and perform flip maneuvers during suborbital launch and landing attempts, while early orbital-class prototypes may use the same thruster system to control their attitude in the vacuum of space.
If last night’s cryo proof test was successful and gave SpaceX the data it needs to give SN11 a good bill of health, the Starship could potentially attempt its first Raptor engine static fire as early Friday, March 12th. Historically, SpaceX has never static fired a Starship prototype less than 12 days after its launch site arrival, meaning that a static fire tomorrow would smash the previous record by a factor of three. As such, it’s more likely that SN11 will need a day or two and be ready for a static fire attempt as early as Monday, March 15th.

Either way, Starship SN11 is undeniably on a faster track than any of its three-engine predecessors and a clean static fire on Friday or Monday would leave a launch next week – SpaceX’s current target– well within reach.
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 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:
Yes

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.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.
Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
