SpaceX eyes major drone ship fleet upgrades and a new rocket recovery robot

SpaceX has kicked off a series of major upgrades planned for its East Coast fleet of drone ships, centered around Just Read The Instructions (JRTI) and most recently culminating in the apparent fabrication of a second tank-like rocket recovery robot.

Back in Q4 2019, West Coast drone ship JRTI officially departed the Port of Los Angeles berth it operated out of for 3+ years — traversing the Panama Canal, making a weeks-long pit-stop in a Louisiana port, and ultimately arriving at Port Canaveral on December 11th. The modified barge spent more than a month relatively untouched – as was the somewhat mysterious cargo it had brought with it from the Gulf Coast – before SpaceX began JRTI’s long-awaited upgrades around a month ago.

For almost half a year, it’s looked like that SpaceX would move its West Coast drone ship to Florida after the company’s Vandenberg Air Force Base (VAFB) pad entered a major lull in launch activities in early 2019. Aside from one launch in June 2019, SpaceX’s West Coast pad has remained unused and that isn’t expected to change anytime soon. With Cape Canaveral potential reopening its dormant polar launch corridor just weeks from now, it’s entirely possible that SpaceX will be able to perform all of its planned launches from Florida alone for at least the next 6-12 months. Targeting more than 30 East Coast launches in 2020 alone, SpaceX could also benefit from at least one additional drone ship to continue high-volume Falcon booster recoveries without ship availability becoming a major launch constraint. Thankfully, JRTI may be the perfect solution.

Informally known as ‘Octagrabber’, a reference to the robot’s primary function, SpaceX has been using the only operational instance of the vehicle on drone ship Of Course I Still Love You (OCISLY) for more than two years, beginning in 2017. While far from autonomous, Octagrabber helps SpaceX’s maritime rocket recovery team minimize the risks workers are subjected to and gives the company a bit more flexibility to attempt Falcon booster landings in less-than-pristine ocean weather.

While Falcon boosters are relatively stable once landed, thanks to the vast majority of their empty mass being concentrated around their nine Merlin 1D engines, even moderate waves can cause them to slip and slide around the drone ship deck.

In fact, the best operational demonstration of the value of Octagrabber-style recovery robots came after SpaceX’s historic Falcon Heavy triple-booster recovery in April 2019 – the first time all three of the rocket’s first stage boosters successfully landed after liftoff. As it turns out, thanks to moderate hardware differences between Falcon Heavy center core boosters and normal Falcon 9 boosters, OCISLY’s Octagrabber robot did not have the attachment mechanisms needed to ‘grab’ the center core (B1055, in this case). In theory, this could be a non-issue but the drone ship unfortunately ran into high seas, making its deck to pitch and tilt and ultimately causing to B1055 to tip over, breaking in half and effectively destroyed the booster.

With Octagrabber robots, drone ships should almost never lose recovered boosters because of high seas (within reason). As such, it should come as no surprise at all that SpaceX is building a new recovery robot for drone ship JRTI – the newest addition to its Florida fleet.

Aside from the discovery of a second Octagrabber being built at SpaceX’s former East Coast Starship factory, the nature of other upgrades planned for drone ship JRTI are more mysterious. For several months, the rocket landing platform has had almost a dozen massive generators and new thruster pods stored on its deck, seemingly waiting on an unknown impetus for their installation. In recent weeks, visible work to prepare the new hardware for installation has begun.

Notably, the thrusters and power supplies that seem destined for installation on JRTI would make for a dramatic upgrade, potentially giving the drone ship more power than the tug boats that must currently tender and tow them to landing zones. In other words, that’s a complicated way of saying that SpaceX may be trying to make drone ship JRTI almost entirely independent of contracted tugboats, potentially simplifying and lowering the cost of booster recoveries.

While less likely, it’s also possible that SpaceX is finally in a position to fully realize the “autonomous” namesake of its autonomous spaceport drone ships (ASDS), with high-powered thrusters potentially giving JRTI the ability to leave port, cruise to Atlantic Ocean landing zones, deploy an Octagrabber, and return to port with a booster – all without humans in the loop. That capability is likely still on the horizon but powerful thrusters and generators would bring port-to-port drone ship autonomy within SpaceX’s grasp in the near future.

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.

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.
