SpaceX CEO Elon Musk has confirmed that Starship and Raptor’s first triple-engine static fire was a success, opening the door for nosecone installation.

Around 3:13 am CDT, October 20th, Starship serial number 8 (SN8) successfully fired up three Raptor engines less than two hours after completing the first successful three-engine preburner test. With zero direct human intervention, SpaceX remotely detanked the rocket’s cryogenic liquid methane and oxygen propellant – the remnants now too warm to be used again in a controlled manner. In an hour or less, SpaceX engineers combed through the data produced and concluded that all three Raptor engines were healthy after their partial ignition test.

Effectively reset to a stable state, SpaceX once again proceeded to load Starship SN8’s propellant tanks with a small amount of supercooled LOx and LCH4, almost exactly mirroring the preburner test. Around 50 minutes after the recycle commenced and 25 minutes after propellant loading kicked off, Starship SN8 ignited three Raptors simultaneously – a major milestone for any rocket engine. Static fire now completed, Starship SN8 has been cleared to become the first operational prototype to reach its full 50m (~165 ft) height.

Shortly before Musk confirmed SN8’s static fire success, SpaceX canceled a preexisting October 20th static fire window and scheduled several new road closures on Wednesday, October 21st. Unlike the company’s recent static fire closures, all but one of which ran from 9pm to 6am, SpaceX’s new Wednesday closures are scheduled from 7am to noon and 3pm to 5pm local (CDT).

While a minor data point, in context with Starship SN8’s static fire success, the closures alone made it clear that SpaceX planned to begin installing Starship SN8’s nosecone on October 21st. Musk confirmed that assumption a few hours after those road closures were published.

It’s not entirely clear but most observers are assuming that Wednesday’s 7am-12pm window is needed to transport a large, new crane the ~2 miles between SpaceX’s Boca Chica factory and launch facilities. Starship SN8’s stacked nose section would then likely be installed on the same self-propelled mobile transporters (SPMT) and rolled to the launch pad from 3pm to 5pm, after which the nose would be lifted and stacked atop Starship SN8.

SpaceX has only fully stacked a Starship prototype once before when Mk1’s nose section was temporarily mated to its tank section to be the centerpiece of CEO Elon Musk’s October 2019 Starship event. It’s unclear why SpaceX wouldn’t simply use one of the mobile cranes its rented for Starship tank section operations (and stacking Mk1) in the past, so it remains to be seen what Wednesday’s road closures will actually be used for.

SpaceX’s road closure plans end with a wildcard, however. Once installed, the plan is to perform a second triple-Raptor static fire while only drawing propellant from SN8’s header tanks – small internal tanks designed to hold landing propellant, one of which is situated at the tip of Starship’s nosecone. On October 21st and 22nd, SpaceX still has two 9pm-6am closures scheduled for “SN8 static fire” testing. Filed early on October 20th, before SN8’s successful static fire, the most likely explanation is a simple clerical error or miscommunication, with Cameron County or SpaceX failing to properly communicate that those subsequent static fire test windows are no longer needed.

If retaining the static fire closures was intentional, it would mean that SpaceX – likely at Musk’s urging – intends to install Starship SN8’s nosecone in a matter of hours. It’s almost inconceivable that Starship SN8’s nosecone – outfitted with multiple gas thrusters, forward flaps powered by Tesla motors, a liquid oxygen header tank, vents, and plenty of plumbing – can be installed and made ready for testing in less than 12 hours. Barring a surprise method of mating SN8’s nose and tank sections, the nosecone will have to be welded to the rest of SN8 and the weld inspected – typically a multi-day process.

Regardless, given how quickly SpaceX moves and how dead-set CEO Elon Musk is at pushing limits and breaking barriers, it seems reasonable to assume that Starship SN8 may be fully integrated and ready for a second static fire test just a handful of days from now. Once completed, SN8 will be ready to attempt Starship’s first high-altitude flight test, launching to ~15 km (~9.3 mi) to attempt an untested skydiver-style descent and landing.

Tesla launches Powerwall Lease for affordable home backup

Published

on

Credit: Tesla

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.

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.

Published

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.
