Northrop Grumman partners with Firefly and SpaceX to save Antares rocket, launch Cygnus spacecraft

Northrop Grumman's next-generation Antares 330 rocket.

Published

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.

SpaceX turned a heralding moment for Starship into its greatest moment

Starship reached orbit despite losing an engine, deployed 26 Starlink V3 satellites on Flight 14.

SpaceX’s Starship reached orbit for the first time on Monday, and for a few nail-biting minutes it looked like it wouldn’t. During ascent on Flight 14, one of Ship 41’s six Raptor engines shut down early, and SpaceX’s livestream host Dan Huot told viewers the team had decided not to commit to orbit. Minutes later, after what Huot described as a lot of conversation in the control room, the final poll came back in favor, and a roughly 19 second burn of a single Raptor pushed the ship into orbit about 170 miles up.

The reversal matters because SpaceX had written the exit ramp into the mission plan. The company said it would only fire the orbital insertion burn if flight controllers confirmed enough backup hardware remained for the deorbit burn, a condition Teslarati laid out ahead of the flight. Losing an engine was exactly the scenario that rule was built for.

Pressing forward fits Elon Musk’s history. Falcon 1 failed three straight times before its fourth launch reached orbit in 2008, with SpaceX nearly out of money, and Starship was developed by flying prototypes until they broke. What changed this year SpaceX going public, and with $SPCX sliding below its IPO price in July when Flight 13 slipped, the short interest climbed significantly, as Teslarati reported at the time. A Starship potentially lost today with revenue generating next-gen Starlink satellites aboard would have landed directly on shareholders.

That pressure showed up after orbit. SpaceX cut a flight planned to last nearly 10 hours to about three, moving splashdown from west of Chile to the North Pacific near Hawaii. SpaceX gave no reason, though Musk said this month the company was being extremely cautious about debris risk. The single Raptor for deorbit worked, and Ship 41 completed its flip and landing burn before breaking apart in the water, an outcome SpaceX expected. Musk has structured SpaceX’s governance to shield long term bets from market pressure.

The payload is the bigger business story. Musk posted that all 26 Starlink V3 satellites deployed and are “operating nominally.” Each V3 is rated for about 1 Tbps of downlink and 160 Gbps of uplink, so this single launch adds roughly 26 Tbps, about 10 times what a Falcon 9 load of V2 Mini satellites adds. The V3 is too large for Falcon 9, making Starship the only vehicle that can build out the planned 100,000 satellite constellation, at up to 60 per flight once it reaches routine service. Unlike the 20 V3 units on Flight 13, which reentered on a suborbital path, these will raise their orbits and could begin serving customers within weeks and bring in hundreds of millions of additional dollars in projected Starlink revenue.

SpaceX has already begun winding down Falcon 9 Starlink launches from Florida in favor of Starship. Reported targets put Flight 15 as early as October 19, leaving about three weeks to diagnose Monday’s engine shutdown before the next orbital attempt.

Tesla Cybercab fleet doubles to well over 100 units

Tesla quietly doubled the size of its Cybercab fleet within the Robotaxi program in Austin, Texas, over the weekend to well over 100 units.

The move not only establishes more of the steering-wheel-less and pedal-less vehicles within the ride-sharing fleet Tesla has been operating for a year, but it also solidifies a more robust Robotaxi fleet as a whole.

Riders started receiving notifications from the Robotaxi app that stated: “Cybercab fleet has doubled: more rides available.”

Tesla first launched rides in the Cybercab in early September, although the Robotaxi fleet has been active for over a year, as rides began last Summer. Cybercab is truly Tesla’s most crucial vehicle release yet, as it is the first car any company has built that is geared toward full-fledged and end-to-end autonomy, never needing human intervention for anything.

Only available in Austin at the current time, Cybercab has two seats and has been spotted testing around various U.S. states and regions; Tesla plans to deploy the Cybercab in various U.S. cities in the coming months as a best-case scenario.

Tesla Cybercab gets initial tie-in to localized, in-house cathode plant

The availability of the Cybercab has doubled from just 58 units last Monday to 125 the following Friday. Marking a substantial increase in Cybercab availability, the additional ride-sharing units are more than welcome, as wait times for Cybercabs, especially, were quite high.

The dramatic increase is a sign that demand for Robotaxi is growing and Tesla is feeling more confident that its driverless ride-hailing suite, especially its Full Self-Driving software, is able to handle any traffic situation without explicit direction or supervision from a human being.

Tesla has a ‘no human contact’ approach for Semi production

Published

on

Tesla is advancing a fully automated pipeline for the 4680 battery cells used in its all-electric Semi, spanning production from Giga Texas through shipment and direct consumption on the line at the new dedicated Semi Factory in Sparks, Nevada.

The approach was outlined by Tesla at its September 24 Semi Handover event, which launched high-volume production at its new 1.8-million-square-foot plant in Nevada, which sits adjacent to Gigafactory Nevada and is designed for an annual production rate of 50,000 trucks per year.

After years of pilot builds and what was a four-year-long redesign of the truck, Tesla moved the Semi from 2170 batteries to its in-house 4680 cells, which are made in Austin. The change cuts battery mass and total energy while holding range, a key step in making volume production a realistic possibility.

Cells will leave Giga Texas in trailers, and at the Nevada Semi plant, Tesla intends for a dedicated line to unload those trailers automatically, station the cells, and feed them straight into pack and vehicle assembly.

Both Lars Moravy, Tesla’s VP of Vehicle Engineering, and Dan Priestley, the Head of Tesla’s Semi program, described the goal as a “zero human touch point” from the moment the trailer arrives in Texas until a finished Semi drives off the production line in Nevada.

The unloading system that Moravy and Priestley described is just one piece of a much broader automation push. The plant uses what Tesla calls the highest-capacity electric monorail conveyance in vehicle manufacturing, carrying frames-in-white simultaneously. Powder-coating replaces conventional paint, and many processes that would normally require operators have been designed out.

Tesla has repeatedly said that “the best part is no part,” and the cell-handling plan extends that philosophy from the cell factory floor in Texas all the way to final assembly in Nevada.

If executed as described, the closed-loop flow would reduce labor, handling damage, and inventory buffers while tightening quality control on a component that represents a large share of the truck’s cost and weight. It also shortens the physical and organizational distance between two factories separated by more than 1,200 miles. The Semi itself now shares a bar-wound stator and other components with the Cybertruck, further linking Tesla’s passenger and commercial production systems.

High-volume output is expected to ramp gradually after the first trucks left the new line in April 2026. Early customers include PepsiCo, DHL, and U.S. Foods. Whether the automated trailer-to-line process reaches the promised zero-touch standard will be visible in the coming months as production scales. For Tesla, the Semi factory is another test of how far it can push “the machine that builds the machine” across sites.
