Northrop Grumman partners with Firefly and SpaceX to save Antares rocket, launch Cygnus spacecraft
Northrop Grumman has announced plans to partner with startup Firefly Aerospace to save (and upgrade) the conglomerate’s Antares rocket, which it uses to launch Cygnus cargo spacecraft to the International Space Station.
The new and improved Antares 330 rocket could debut as early as late 2024. The existing Antares 230 rocket has just two launches left before a lack of new hardware from crucial Ukrainian suppliers will permanently ground it – a time Northrop Grumman estimates will come as early as spring (Q2) 2023. To fill Antares’ 18-month availability gap, Northrop Grumman says it has purchased three SpaceX Falcon 9 launches to continue Cygnus space station cargo deliveries largely unabated.
In some ways, Northrop Grumman’s decision to purchase alternate launch services from SpaceX is surprising. After Antares suffered a catastrophic failure during an operational Cygnus launch in October 2014, Orbital Sciences chose to purchase three Atlas V launches from the United Launch Alliance (ULA) to ensure continued cargo deliveries while it attempted to return its own rocket to flight. Antares fully took over in 2017 after returning to flight in 2016.
However, seven or so years later, ULA is on the verge of retiring Atlas V and has already sold all remaining Atlas V launch contracts. Meanwhile, its next-generation Vulcan Centaur rocket is years behind schedule and unlikely to debut before 2023, making it extremely unlikely that ULA would have been able to fulfill Northrop Grumman’s desire to preserve its existing Cygnus launch schedule. It’s possible that Vulcan could have gotten the job done, but each Cygnus launch would have likely ended up several months (or more) behind schedule, thus requiring SpaceX and future provider Sierra Nevada Corporation to fill in the space station resource gaps Cygnus would leave.
With the benefit of hindsight and knowing that Antares 330 is unlikely to debut before late 2024 or 2025, it’s clear that SpaceX was the only viable option. Thanks to SpaceX operating in an entirely different universe of launch cadence and availability relative to the rest of the world, the company should have no issue whatsoever substituting a few of the dozens of Falcon 9 Starlink launches likely planned in 2023 and 2024 with Cygnus space station resupply runs.
Northrop Grumman’s decision comes almost four months after Russia’s second illegal invasion of Ukraine, an action that immediately threw the future of its Antares rocket into question. The only major components of Antares-Cygnus Northrop Grumman (through its 2018 acquisition of Orbital ATK) is responsible for building are the rocket’s Castor 30XL second stage and Cygnus’ service module. Cygnus’ silver pressure vessel is built by Thales Alenia Space, the payload fairing is built by RUAG, the Antares booster engines are supplied by Russia’s NPO Energomash, and the Antares booster structures are built by Ukraine’s Yuzhnoye SDO and Yuzhmash.
Now embroiled in an open shooting war begun by Russia, Ukraine’s aerospace industry has been on borrowed time for several months. In July, the Yuzhmash factory was reportedly struck by cruise missiles, killing several people and presumably damaging the facility. Northrop Grumman’s August 8th announcement that it US startup Firefly Aerospace will build a domestic replacement for the Antares first stage all but guarantees that its former Ukrainian partners are no longer able to supply rocket hardware.
The Antares 330 booster Firefly intends to build for Northrop Grumman will be substantially larger and “significantly increase” the rocket’s performance to low Earth orbit (LEO), which currently sits at 8 tons (~17,500 lb). Intriguingly, the booster Firefly will supply appears to be the latest iteration of the first stage of the medium-lift Beta rocket the startup has been working on for some time. According to Firefly’s recently updated Beta webpage, the next-generation rocket is expected to measure 4.32 meters (14.1 ft) wide and 55.7 meters (182.5 ft) tall; produce about 720 tons (1.6M lbf) of thrust in vacuum, and launch up to 13 tons (28,700 lb) to LEO.

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
Investor's Corner
Tesla’s flying Roadster just revealed something bigger than the car
Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.
The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.
Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.
The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.
The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.
Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.
The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.
Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.
