SpaceX President and Chief Operating Officer Gwynne Shotwell recently provided information about the company’s Starlink satellite internet constellation after a panel at the International Aeronautical Congress in Washington D.C. Shotwell spoke of a partnership with the U.S. military and just how far she believes Starlink is ahead of rival mega-constellation efforts.

While competitors are still developing very early prototypes and worrying about launch options, SpaceX has already launched 60 Starlink ‘v0.9’ satellite prototypes, 50 of which continue to successfully operate in low Earth orbit approximately half a year after launch. As part of a $29M contract awarded in late-2018, SpaceX is also working directly with the U.S. Air Force to test military applications of commercial space-based internet.

As previously reported by Teslarati, SpaceX was awarded a $29 million contract in December 2018 to collaborate with the U.S. Air Force Strategic Development Planning and Experimentation Office. Together, the organizations are testing potential military applications of Starlink satellite internet, as well as prospective constellations from other companies like Telesat.

The technical viability and utility of beaming high speed, low-latency broadband internet directly into the cockpits of military aircraft is being tested under a program called Global Lightning. SpaceX has engaged the initiative and was awarded $29M to pursue development and testing, far more than any other contract recipient. In October 2019, SpaceX and the USAF began publicly discussing the latest results of that effort to test Starlink’s capabilities in the realm of in-flight connectivity. As reported by SpaceNews, SpaceX COO Gwynne Shotwell revealed that Starlink had successfully demonstrated a data link to the cockpit of a military aircraft with a bandwidth of 610 megabits per second (Mbps), equivalent to a gigabyte every ~13 seconds.

Following a previous speaking engagement on Oct. 15th at the Association of the U.S. Army’s annual conference, Shotwell and U.S. Army officials provided further insight regarding military applications of Starlink. Army officials spoke about the possibility of using Starlink satellite internet and other prospective constellations to support the military’s rapidly growing demand for high-speed communications.

During the panel with U.S. Army officials, Shotwell stated that “SpaceX is new to this forum and this service,” when addressing the possibilities that SpaceX could provide for the U.S. military. While working with the military is not a new concept to SpaceX, serving as a satellite communications provider would be unlike anything the company has yet attempted.

Up next, the USAF has plans to install Starlink terminals and test connectivity with an AC-130 gunship and a KC-135 tanker aircraft.

Falcon 9 to support frequent Starlink launches – customers and rocket reusability benefit

While Shotwell acknowledged the potential of a partnership with the US. military, she also noted that Starlink is first and foremost a commercial business meant to enhance the internet experience globally and nominally provide connectivity to anyone that wants it. She further noted that Starlink would remain an “additive to [SpaceX’s] business,” implying that it will not supersede SpaceX’s current launch service business.

Intriguingly, this is utterly counter to forecasts SpaceX has provided investors over the last several years, in which Starlink – if successful – would almost certainly come to produce one or two magnitudes more income than launch services ever could. Shotwell – speaking to a variety of US military (and Air Force) officials – may have wanted to avoid sending the message that SpaceX’s launch services business – crucial to the US military – might soon be absolutely dwarfed by Starlink revenue.

Previously hinted at by CEO Elon Musk, SpaceX hopes that revenue from Starlink will enable the company to independently fund the development and mass-production of its next-generation Starship launch vehicle, eventually enabling a permanent, large-scale human presence on Mars.

Currently, SpaceX’s Starlink plans involve several distinct phases, beginning with ~1500 satellites around 500km, another ~2900 around 1000 km, and an additional ~7500 in the 300-400 km range. Finally, SpaceX recently revealed even longer-term plans for Starlink that could involve launching up to 42,000 satellites, all in the name of expanding network coverage and bandwidth – pending, of course, consumer demand. To accomplish that feat, SpaceX will have to push rocket reusability to the absolute limits, beginning with Falcon 9 boosters and fairings and ultimately moving to Starship. According to Shotwell, “(SpaceX’s) intent is to use Starlink to push the capability of those boosters and see how many missions they can do.”

SpaceX’s next Starlink mission – also the company’s next mission and first launch in more than three months – will simultaneously attempt two new rocket reusability firsts, marking the first time that SpaceX has reused a Falcon payload fairing and the first time a single Falcon 9 booster has launched four times. Starlink-1 is scheduled to lift off no earlier than 9:55 am ET (14:55 UTC), November 11th.

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.
