SpaceX’s workhorse Falcon 9 rocket is ready for the company’s 12th launch this year, set to send a reused Cargo Dragon spacecraft on its way to the International Space Station (ISS) and conclude with a surprise drone ship landing attempt.

SpaceX is about eight hours out from launching CRS-19, set to become Cargo Dragon’s 20th orbital mission and 19th space station rendezvous and resupply. It will also be the second time a single Cargo Dragon capsule flies its third orbital mission and the eight Dragon reuse overall, continuing proof that SpaceX is by far the leading global expert in launch vehicle and orbital spacecraft recovery and reuse.

Set to lift off no earlier than 12:51 pm ET (16:51 UTC), December 4th, CRS-19 will see flight-proven Cargo Dragon capsule C106 launch atop a new expendable trunk and upper stage, as well as a new Falcon 9 booster – an increasingly unusual sight. After a Falcon Heavy Block 5 launch completed earlier this year, SpaceX passed a threshold where it had recovered more boosters after launch than it had expended, equating to 40+ successful landings. Since Falcon 9 Block 5 – a reusability and reliability-focused upgrade – debuted in May 2018, sooty (i.e. flight-proven) boosters have become an increasingly common sight.

Between Falcon Heavy’s two 2019 launches, four new boosters marked their flight debut, while Falcon 9 missions have only debuted two new boosters – soon to be three after CRS-19. In other words, as of today, 7 of Falcon 9’s 9 2019 launches have involved flight-proven boosters – more than 75%. In fact, Block 5 is proving so robust that SpaceX has actually intentionally slowed down booster production at its Hawthorne, CA factory, hoping to instead treat its currently flightworthy rockets as a true fleet, cycling through them to launch dozens of missions.

Cargo Dragon with a (rare) side of drone ship

Beyond the rarity of a new booster’s launch debut and Cargo Dragon’s increasingly impressive history of reusability, CRS-19 – as discussed at length in earlier articles – will also see Falcon 9 booster B1058 attempt to land aboard drone ship Of Course I Still Love You (OCISLY) some 350 km (200 mi) downrange. Aside from CRS-17’s Crew Dragon explosion-related drone ship landing in May 2019, all CRS mission booster recoveries since April 2016 have landed (or at least attempted to land) at SpaceX’s Cape Canaveral-based LZ-1 or LZ-2 landing pads.

Close to shore by average drone ship landing standards but a cross-country jaunt compared to CRS-17’s unusual May 2019 booster landing aboard OCISLY, SpaceX explained the odd booster recovery plans in a routine prelaunch press conference yesterday afternoon.

“[After Dragon is deployed and CRS-19’s launch concludes], SpaceX is going to perform an…ambitious coast test, requiring larger propellant margins that must be withdrawn from Falcon 9’s own landing propellant budget.”

In short, SpaceX needs to leave more propellant for the upper stage, thus limiting B1058’s ability to boost all the way back to the Florida coast. Instead, it will only partially slow its Eastbound velocity, still leaving enough margin for drone ship OCISLY to station relatively close to the Florida coast compared to more common (and more demanding) booster recovery profiles.

All told, SpaceX says Falcon 9’s upper stage will attempt to perform a six-hour coast (“thermal test”) after CRS-19, concluding with a final Merlin Vacuum engine reignition and deorbit burn, similar to a test performed after CRS-18’s recent July 2019 launch. These tests are meant to satisfy what SpaceX described as the requirements of “other customers”, of which the USAF is by far the best known for its long-duration coast demands. For an upper stage powered by cryogenic liquid fuel, remaining fully functional for hours in orbit is one of the single greatest technical challenges that face modern rocketry.

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.
