SpaceX set for second weekend launch, new titanium grid fins to be tested

Published

on

After a highly successful Friday launch and recovery of a reused Falcon 9, a second vehicle is preparing to launch on the opposite coast of the United States. Scheduled to lift off at precisely 1:25 p.m. PST, this mission will see a brand new Falcon 9 lift Iridium’s second set of ten NEXT satellites, after which the first stage will attempt to land in the Pacific Ocean aboard Just Read The Instructions, SpaceX’s West Coast drone ship.

If the schedule holds, the 46 hours separation between launches will make SpaceX one of very few entities to have launched the same vehicle in such close succession. While Russia/USSR and the Republic of China have tended to routinely launch missions with as few as a handful of hours in between, it is extremely rare in the United States, and such an accomplishment will likely make SpaceX the second private company to ever conduct two launches in under 48 hours.

This turnaround, which COO Gwynne Shotwell clarified could safely be as few as 24 hours, bodes extremely well for SpaceX’s and Musk’s goal of being able to launch every 24 hours. With the COO of the company already under the impression that 24 hours would be safely and reliably achievable, all that lies in the way of 24 hour cadence is pad availability. With current cadence suggesting that at least two weeks of down time is needed after a launch to verify pad health, the late-fall reactivation of Launch Complex 40 and eventual activation of SpaceX’s planned Boca Chica, Texas launch facility will give SpaceX three general-purpose pads and one limited use-case pad (Vandenberg Air Force Base) to launch from by late 2018 or early 2019. Three general purpose pads would allow SpaceX to launch every four or five days, assuming no improvements in pad resilience and autonomy, and this weekend’s back to back launches will demonstrate that SpaceX is easily capable of fully taking advantage of those three (or four) pads once they are all active.

As for the launch today, it will debut some intriguing new hardware intended to improve the ease of reusability for the first stage. Musk offered a tweet storm last night and SpaceX one or two photos to explain the utility of the vehicles distinctive and unusual black grid fins. Ready to launch in just over an hour from Vandenberg Air Force Base, Falcon 9 and its new grid fins will place the next ten iridium NEXT satellites in Low Earth Orbit. The first stage will then proceed to the autonomous spaceport drone ship Just Read The Instructions, while testing its rather fancy titanium grid fins. Considerably larger than their aluminum predecessors, this new iteration of grid fins will is intended to both provide more control authority and glide capability in anticipation of the Falcon Heavy, while also offering improve resilience to the extreme heat and forces grid fins must necessarily cope with during reentry. You may have noted grid fins appearing to glow red and orange with the heat of reentry in past live coverage, and recovered stages demonstrate just how harsh high temperatures can be to aluminum. Titanium is famously resistant to heat and will thus optimally be able to be reused with no refurbishment or replacement whatsoever.

With the launch just over an hour out and no current known issues, you can watch SpaceX’s regularly amazing live coverage of the launch at spacex.com/webcast.

Eric Ralph is Teslarati's senior spaceflight reporter and has been covering the industry in some capacity for almost half a decade, largely spurred in 2016 by a trip to Mexico to watch Elon Musk reveal SpaceX's plans for Mars in person. Aside from spreading interest and excitement about spaceflight far and wide, his primary goal is to cover humanity's ongoing efforts to expand beyond Earth to the Moon, Mars, and elsewhere.

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

on

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.
