Northrup Grumman’s Antares set for its swan song launch
Later this evening at 8:31 p.m. ET (00:31 UTC on the 2nd), the Northrup Grumman Antares 230+ rocket is scheduled to launch its final resupply mission to the International Space Station.
The rocket will lift off from Launch Pad 0 at the Mid Atlantic Regional Spaceport on Wallops Island in Virginia, carrying the Cygnus cargo vehicle. Cygnus will be loaded with 8,200 lbs (3,719 kg) of supplies and experiments for the orbiting outpost.
The Ukrainian-built Antares launch vehicle has only been used to launch resupply missions to the ISS since its debut launch in April 2013, then owned by Orbital Sciences. Since its debut, it has had one failure and, as a result, underwent its first upgrade.
The first version of the rocket used NK-33 engines built by the Soviet Union in the 1970s, the engines were then bought by Aerojet-Rocketdyne and modified for use on the Antares rocket. The engines were renamed the AJ-26.

On the rocket’s 5th mission, one of those engines failed in spectacular fashion when a liquid oxygen turbopump with manufacturing defects failed 6 seconds after liftoff, causing Antares to fall back down onto the launch pad and explode.
This set off a chain of events for U.S. launch providers as the United States banned further purchasing of Russian-made engines in December 2014, a decision that was altered just a year later to accommodate United Launch Alliance, whose Atlas V rocket uses Russian-made RD-180 engines.
Following the failure, Antares was switched over to using the RD-181 engines and thus creating the next Antares variant, the 230 series of the rocket. This version would go on to launch 12 more times before the Russian invasion of Ukraine, and the resulting sanctions against Russia forced Northrup Grumman to end its reliability on the Ukrainian-built first stage and Russian engines.
In August 2022, Northrup Grumman announced they had contracted Firefly Aerospace to produce a new medium-lift rocket for the company that will be called the Antares 330. The 330 series will use 7 Miranda engines from the company. The 330 series upper stage will be the Castor 30XL solid-fueled rocket motor, with later versions using a vacuum-optimized Miranda engine to provide extra performance.

While the Antares 330 rocket is being designed and built, Northrup Grumman has contracted SpaceX to launch 3 Cygnus resupply missions in order to fulfill their contract with NASA.
Northrup Grumman has said they expect to be able to launch the Antares 330 by Summer 2025.
The current weather outlook shows an 80% chance of acceptable conditions at lift-off. NASA will host a live stream of the launch on its YouTube page.

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.

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 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:
Yes
— Elon Musk (@elonmusk) August 12, 2026
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.”

Impressive! https://t.co/FVAkzFLz3r
— Ron DeSantis (@RonDeSantis) August 11, 2026
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.
