This week, Firefly Aerospace introduced their first profitable scorching hearth check of their Miranda rocket engine that would be the first stage of Northrop Grumman’s Antares 330 and their very own Medium Carry Automobile.
The check is a serious step ahead for the corporate as they’re aiming to fulfill a mid-2025 launch goal for the brand new rocket.
The MLV (and Antares 330) will make the most of 7 Miranda engines on the primary stage and can be able to producing 1.6 million kilos of thrust and the power to ship as much as 10,000 kg of payload to the Worldwide Area Station on the Antares 330.

The MLV can be able to sending as much as 16,000 kg low Earth orbit as it can make the most of the Miranda vacuum engine whereas the Antares 330 will use a Castor 30XL solid-fueled rocket motor for its first launches earlier than an eventual transition to the Miranda vacuum engine.
The Miranda engine makes use of liquid oxygen and rocket propellant-1 (RP-1), and triethylaluminium-triethylborane to ignite the engine, which produces the fast inexperienced flash seen within the photograph above. The MLV will stand 55.7 meters (183 toes) tall and may have a 5.2-meter payload fairing
CEO of Firefly Aerospace, Invoice Weber, had this to say, “The unbelievable progress on our Miranda engines – designed, constructed, and examined in-house in simply over a 12 months – is one other instance of Firefly setting a brand new normal within the trade, constructing on the legacy of Firefly’s quickly developed Reaver and Lightning engines, Miranda is the quickest propulsion system we’ve constructed and examined so far. This achievement displays our fast, iterative tradition and our vertically built-in strategy that permits us to shortly scale up the flight-proven engine structure from our small launch automobile, Alpha, to our Medium Launch Automobile.”
The subsequent step for Firefly can be a full-duration hot-fire of the Mirdan engine that may final roughly 206 seconds.
As for what’s subsequent for the corporate, they’re focusing on a launch in December for Flight 004 of their Alpha rocket that may carry a Lockheed Martin electronically steerable antennae payload demonstrator to low Earth orbit.
