SpaceX has completed its 52nd successful Falcon 9 launch in 52 weeks, sustaining an average cadence of one launch per week for a full 12 months.

Simultaneously, the Starlink 4-2 rideshare mission set a new record for Falcon 9 booster reuse, marked SpaceX’s 150th consecutively successful launch, and was one of the most complex commercial launches it has ever performed.

In addition to 34 new Starlink V1.5 satellites that joined almost 3000 other working SpaceX spacecraft in orbit, Starlink 4-2 deployed the company’s largest rideshare payload yet – AST SpaceMobile’s 1.5-ton (~3300 lb) BlueWalker 3 communications satellite.

Falcon 9 lifted off on schedule with the combined 12-ton (~26,500 lb) payload safely secured inside its composite payload fairing at 9:20 pm EDT (01:20 UTC) on Saturday, September 10th. Tasked with lifting the rocket’s expendable upper stage, recoverable fairing, and payload most of the way out of Earth’s atmosphere was Falcon 9 booster B1058, a nine-engine first stage that debuted by launching two NASA astronauts in May 2020.

28 months later, B1058 lifted off with Starlink 4-2 and BlueWalker 3 on its 14th spaceflight and orbital-class launch, breaking Falcon 9’s booster reuse record. The rocket performed no differently than it had every time previously, burning for a bit less than three minutes before deploying the upper stage and returning to Earth. About nine minutes after liftoff, B1058 safely touched down on drone ship A Shortfall Of Gravitas (ASOG), likely setting the booster up to break its own record before the end of 2022. With 13 launches already under their belts, boosters B1051 and B1060 will likely follow B1058 past the same 14-flight milestone in the near future.

Once free from the booster, Falcon 9’s expendable upper stage kicked off SpaceX’s most complex commercial launch ever. Measuring about six minutes long, the first and longest burn brought the second stage and payload into an elliptical orbit a few hundred kilometers above Earth’s surface. A second burn followed about 45 minutes after liftoff, raising the low end of that ellipse to deploy BlueWalker 3 into a circular orbit around 500 kilometers (~310 mi). Using a massive antenna, AST SpaceMobile’s first large satellite prototype will eventually attempt to directly communicate with mobile phones to provide a level of connectivity equivalent to 5G/LTE – all from space.

Once free of its rideshare payload, the focus shifted to Starlink. In theory, SpaceX could have taken the easy way out and significantly simplified the mission by deploying all 34 satellites at the same altitude as BlueWalker 3, simultaneously allowing them to reach their operational 540-kilometer (~336 mi) orbits in days instead of months. Instead, SpaceX pursued an exceptionally complex mission requiring five burns from Falcon 9’s upper stage.

After deploying BlueWalker 3, Falcon 9 S2 lowered one end of its orbit at around T+67 minutes, followed by a fourth burn to lower the other end almost two hours after liftoff. The upper stage then spun up end over end and eventually released all 34 Starlink satellites at an altitude of ~335 kilometers (~208 mi), where debris and faulty satellites will take days – rather than years – to reenter Earth’s atmosphere and burn up.

Once it unfurls, BlueWalker 3 will likely have the largest commercial communications antenna ever deployed in space, featuring an area of almost 700 square feet. (64 m^2).

While SpaceX doesn’t confirm post-payload operations, Falcon 9 S2 was also scheduled to perform a fifth and final burn to quickly deorbit itself, ensuring that the mission only produced five pieces of benign debris. At their very low orbits, those five pieces (four ‘tensioning rods’ and the BlueWalker 3 payload adapter) will pose next to no threat to other spacecraft or rockets and should reenter within a few weeks.

Starlink 4-2 was SpaceX’s 52nd successful Falcon 9 launch since September 14th, 2021, meaning that the company has technically already achieved CEO Elon Musk’s goal of 52 launches in one year – albeit not a calendar year. Perhaps even more impressive, the mission was SpaceX’s 150th consecutively successful Falcon launch. No other single rocket (Falcon 9) or rocket family (Falcon) has launched more times in a row without failure.

Finally, Starlink 4-2 was SpaceX’s 42nd launch of 2022. If the company continues its average cadence over the last three months, it could end 2022 having completed more than 60 Falcon launches in one calendar year.

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.

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.
