According to an official statement, SpaceX’s satellite mass production is “well underway” and the first batch of operational Starlink satellites are already in Florida for their May 2019 launch debut.

Simultaneously, the FCC has granted SpaceX’s request to modify the deployment of its first 1584 Starlink satellites, permitting the company to lower their orbit from approximately 1150 km to 550 km (715 mi to 340 mi). A lower insertion orbit should improve Falcon 9’s maximum Starlink payload, while the lower operational orbit will help to further minimize any risk posed by orbital debris that could be generated by failed SpaceX satellites.

Above all else, SpaceX’s confirmation that the first batch of Starlink satellites are already in Florida drives home the reality that the company’s internet satellite constellation is about to become very real. Said constellation has long been the subject of endless skepticism and criticism, dominated by a general atmosphere of dismissal. There is no doubt that Starlink, as proposed, is an extraordinarily ambitious program that will cost billions of dollars to even begin to realize. SpaceX will have to find ways to affordably manufacture and launch ~11,900 satellites – together weighing something like 500 metric tons (1.1 million lbs) – in as few as nine years, start to finish.

As of November 2018, there are roughly 2000 satellites operating in Earth orbit, meaning that SpaceX’s full Starlink constellation would increase the number of functional satellites in orbit by a factor of almost seven. Just the first phase of Starlink (4409 satellites) would more than triple the number of working satellites in orbit. To meet the contractual requirement that SpaceX launch at least half of Starlink’s licensed satellites within six years of the FCC granting the constellation license, the company will need to launch an average of ~37 satellites per month between now and April 2024. By April 2027, SpaceX will either have to launch all ~2200 remaining Phase 1 satellites or risk forfeiture of its Starlink constellation license. Same goes for the ~7500 very low Earth orbit (VLEO) satellites making up Starlink’s second phase, albeit with their launch deadlines instead in November of 2024 and 2027.

In fact, if SpaceX wants to preserve the separate FCC license for its VLEO Starlink segment, it will actually need to build and launch an average of 100 satellites per month – 20+ per week – for the next five years. In no way, shape, or form is the monthly production of 100 complex pieces of machinery unprecedented. It is, however, entirely unprecedented – and by a factor of no less than 10 – in the spaceflight and satellite industries. Accomplishing that feat will require numerous paradigm shifts in satellite design, manufacturing, and operations. It’s hard to think of anyone more up to the challenge than SpaceX but it will still be an immensely difficult and expensive undertaking.

“Baby” steps

According to SpaceX, the first 75 operational Starlink satellites will be significantly less refined than those that will follow. Most notably, they will eschew dual-band (Ku and Ka) phased array antennas, instead relying solely on Ka-band communications. The second main difference between relates to “demisability”, referring to characteristics exhibited during reentry. The first 75 spacecraft will be less refined and thus feature a handful of components that are expected to survive the rigors of reentering Earth’s atmosphere, creating a truly miniscule risk of property damage and/or human injuries. Subsequent Starlink vehicles will incorporate design changes to ensure that 100% of each satellite is incinerated during reentry, thus posing a ~0% risk on the ground.

In a sense, the first 75 Starlink satellites will be an in-depth demonstration of SpaceX’s proposed constellation. Depending on how the satellites are deployed in orbit, SpaceX’s development team could potentially have uninterrupted access to the orbiting mini-constellation. There will also be constant opportunities to thoroughly test SpaceX’s network architecture for real, including general downlink/uplink traffic, surge management, satellite handoffs, and the laser interlinks meant to join all Starlink satellites into one giant mesh network.

SpaceX has yet to announce the precise number of Starlink satellites that will be aboard Falcon 9 on the rocket’s first dedicated internal launch. More likely than not, the constraining factor will be the usable volume of SpaceX’s payload fairing, measuring 5.2m (17 ft) in diameter. For Flight 1, 10-20 satellites is a reasonable estimate. Likely to weigh around 10,000 kg (22,000 lb) total, the first Starlink payload will be delivered to a parking orbit of ~350 km (220 mi), easily allowing Falcon 9 to return to SpaceX’s Florida Landing Zone or perform a gentle landing aboard drone ship Of Course I Still Love You (OCISLY). The satellites will use their own electric Hall thrusters to reach their final destination (550 km).

According to SpaceX CEO Elon Musk, the first Falcon 9 fairing reuse may also happen during an internal Starlink launch, although it’s unclear if he was referring to Starlink Launch 1 (Starlink-1) or a follow-up mission later this year.

For now, SpaceX is targeting a mid-May for its first dedicated Starlink mission, set to launch from Launch Complex 40 (LC-40). Up next for LC-40 is SpaceX’s 17th operational Cargo Dragon launch (CRS-17), delayed from April 26th and April 30th to May 3rd.

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

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.
