SpaceX aborts Starship launch after Raptors produce too much thrust
Update #3: SpaceX CEO Elon Musk says that Starship prototype SN10 automatically aborted a 2:15 pm CST (UTC-6) launch attempt after the rocket determined that its three Raptor engines were producing too much thrust.
Instead of scrubbing for the day, Musk says that SpaceX will instead increase the flight computer’s thrust limits and try again as early as 4:30 pm CST – still well before today’s window closes at 6:30 pm. SpaceX ended its webcast but will start a second webcast a few minutes prior to the next launch attempt.
Update #2: As of Wednesday morning, SpaceX has officially confirmed that Starship is on track for a third high-altitude launch and ‘bellyflop‘-style landing attempt sometime later today.
As of 11am CST (UTC-6), FAA approval is in hand, weather is encouraging, Starship prototype serial number 10’s (SN10) flaps have been unchained, and SpaceX has cleared the launch site – all signs that the rocket’s launch attempt is imminent. Much like SN8 and SN9 coverage, SpaceX says it will make a public livestream of SN10’s launch available to the public “a few minutes” before liftoff. Stay tuned and follow along with NASASpaceflight’s live coverage in the meantime.
Update: SpaceX has asked Boca Chica Village residents to prepare to evacuate the area as early as Wednesday morning for Starship’s third high-altitude launch and landing attempt.
The odds of things going so wrong that a Starship launch could actually end with a prototype impacting at or near the Village and the handful of non-employee holdouts still residing there are minuscule. However, FAA safety regulations and SpaceX’s contingent launch license mean that evacuations are now a routine part of Starship’s high-altitude flight tests since Starship SN8 took the first step beyond short hops. While undeniably inconvenient for the few remaining residents, today’s evacuation notice – short of an official SpaceX.com confirmation – does serve as the ultimate sign that Starship SN10’s first launch attempt is firmly scheduled on Wednesday, March 3rd.
With FAA approval in hand, weather rapidly improving, and the latest rocket prototype seemingly raring to go, the stars are aligning for SpaceX’s third high-altitude Starship launch and first triple-engine landing attempt.

As of March 1st, publicly-available FAA “temporary flight restrictions” (TFRs) and weather forecasts both agree that SpaceX is currently preparing to launch Starship serial number 10 (SN10) as early as Wednesday afternoon CST (UTC-6), March 3rd. Barring surprises, that gives SpaceX a healthy three-day period to account for any potential technical or weather-related delays.
Originally scheduled as early as the last week of February, unspecified delays pushed Starship SN10’s launch debut schedule into March. In general, the vehicle’s path to flight has been much smoother than Starship SN8 and SN9, both of which ran into hardware bugs and opaque FAA licensing issues. With Starship SN10, the FAA approved SpaceX’s “modified” launch license well before the company was ready for flight – and even before the rocket had attempted its first static fire.
Unlike Starships SN8 and SN9, both of which took anywhere from 6-10 weeks to go from rolling off the factory floor to preparing for their first launch attempts, SN10’s first launch attempt appears likely to occur less than five weeks after the rocket arrived at the launch site. The sequential improvements in efficiency and reliability between those three prototypes is a fundamental part (or goal, at least) of SpaceX’s iterative development process.
Still, Starship SN10’s preflight flow wasn’t completely free of drama and SpaceX ultimately put the rocket through a second triple-Raptor static fire after the first test revealed an issue with one of those engines. SpaceX swapped that faulty engine out in record time and fired up SN10 again less than 48 hours after test #1, seemingly producing more satisfactory results the second time around.
Unlike its predecessors, SN10 will also debut a new triple-engine approach to landing, aiming to increase redundancy and boost the odds of a successful touchdown even if one of the Starship’s three Raptors fail during a last-second flip maneuver. Building on the failures of SN8 and SN9, it’s safe to say that SN10 has the best shot yet at sticking the landing.
TFRs show that two earlier launch windows on Monday and Tuesday (March 1st and 2nd) were canceled, leaving only the Wednesday, March 3rd airspace closure request still open. Wednesday was then backed up with two alternate windows on Thursday and Friday not long after.
Hardware-wise, Starship SN10’s cherry-on-top (an explosives-based flight termination system or FTS) was installed on February 28th. In the event that Starship loses control and strays past a certain point outside of its approved trajectory, that FTS would explode, breaching the rocket’s propellant tank, triggering vehicle breakup, and thus preventing it from harming the local populace. All told, SpaceX confirmation of a Wednesday launch attempt – and another official webcast – should be imminent. Stay tuned!

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.
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
— Elon Musk (@elonmusk) August 12, 2026
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.
