SpaceX’s BFR Mars rocket tooling makes rare appearance in LA Port tent

Published

on

After nearly ten weeks hidden inside the company’s Port of Los Angeles tent, SpaceX’s main BFR manufacturing tooling made another brief appearance on July 1, showing off a new support structure and equipment that enables the entire device to spin and easily lay down layers of carbon fiber to construct the first Mars rocket prototype propellant tanks.

Based on photos taken of the large composite production equipment – known as a mandrel – in April 2018, as well as a photo released by CEO Elon Musk around the same time, it appears either that major modifications were made in the past two months or that an entirely new tool has been delivered to the dockside tent over the same period of time. Given that the shipment of the first hardware and its arrival at Port LA itself managed to slip beneath the eyes of local observers, there certainly is no reason that the same thing couldn’t be repeated. The mandrels and other production tooling SpaceX has acquired from Ascent Aerospace are likely shipped to their final destination disassembled.

More relevant, however, is the probability that SpaceX will need more than a single mandrel to produce BFR ship and booster prototypes on anything faster than geological timescales. In fact, if (very) rough size estimates produced from Musk’s shared photo are correct, two (or even three) 16-meter long mandrels would almost perfectly mesh to create the Spaceship’s own massive 48-meter length, although the reality would be far more complex than a simple feat of 1+1+1 thanks to the complex front and rear shapes of the BFR upper stage.

Two mandrels would also ensure that SpaceX is able to rapidly prototype, test, and re-prototype BFR hardware while the company refines designs and moves into full-scale flight hardware production and flight testing, at least at the prototype phase. Recently, several BFR and Mars rocket-focused job postings were spotted with specific requirements related to composite-composite and composite-metal joining, a young but rapidly advancing subset of skills necessary to efficiently and economically produce massive structures primarily made up of composite materials.

Boeing’s 787 program, composed of 50% composites, is a strong example with each fuselage broken into a number of smaller segments that are later joined together with tolerances on the order of 1/5000 of an inch to avoid damage to the composite sandwich structures within. Long-lived, reliable, and resilient segmented composite structures are thus well-established as a viable solution, although Boeing is one of precious few entities able to lay claim to such mass-production successes. Ultimately, SpaceX does not need to start from scratch (even if they could, or still may) in order to successfully build the ultra-reusable Mars rocket they aspire to.

Tesla launches Powerwall Lease for affordable home backup

Published

on

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

Published

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.
