FULL STORY ======================================================================Texas-ba sed small launch company Firefly Aerospace is preparing to jumpstart its 2023 campaign with the launch of FLTA003 the third flight of its Alpha launch vehicle as part of a dedicated mission for the U.S. Space Force (USSF). Liftoff from Space Launch Complex 2 West (SLC-2W) at Vandenberg Space Force Base in California is currently scheduled to occur no earlier than Thursday, Sept. 14 at 6:57 PM PDT (01:57 UTC on Friday, Sept. 15). The mission colloquially known as VICTUS NOX, which translates to conquer the night in Latin will serve as a demonstration of the United States capability to quickly place a satellite in orbit in response to a national security threat, if the need ever arises. Firefly was awarded the mission in October 2022
under the Orbital Services Program 4 contract.

Launch update: Our next launch, FLTA003, will support the @SpaceForceDoD responsive space mission, VICTUS NOX. Were in the final integration of our Alpha rocket and will soon stand ready for the 24-hour call-up. Were honored to work with this incredible team! #PartnersInSpace

As the launch provider, Firefly is expected to complete certain mission readiness milestones under a set timeframe as specified by the USSF. For example, the company had 60 hours of advance notice to encapsulate and mate the VICTUS NOX payload to the Alpha rocket before rolling the vehicle stack
to the launch pad. At T-24 hours before liftoff, another notice will be provided specifying the launch window timing and orbital parameters. The payload for the VICTUS NOX mission was manufactured by Millennium Space, a subsidiary of The Boeing Company. Most of the specifics regarding the satellite are unknown, though it has been confirmed that it will perform a space domain awareness mission while in space. This entails the tracking and monitoring of other objects in orbit, along with predicting possible orbital threats. VICTUS NOX will serve as the third mission launched by Alpha a two-stage small-lift orbital-class rocket developed by Firefly Aerospace.
With a maximum payload capacity of 1,170 kilograms to low-Earth orbit (LEO) and standing at approximately 29.5 meters tall, Alpha boasts a higher mass-to-orbit capability than other small satellite launch vehicles, such as Rocket Labs Electron (300 kg to LEO). Fireflys first orbital launch attempt with Alpha in September 2021 ended in failure after an engine shutdown at
T+14 seconds into the flight, eventually leading to a loss of control at approximately two and a half minutes after liftoff and the termination of the mission by ground controllers.

As such, the payloads reentered the Earths atmosphere approximately one week after launch. In a social media post following the launch of To the Black, Firefly stated that only minor tweaks needed to be made to Alpha before the next mission, according to preliminary reviews. Alphas first stage features four Reaver 1 engines, which are fueled using RP-1 kerosene and liquid oxygen (LOX). Each Reaver 1 motor produces a maximum thrust of approximately 200 kN and achieves a specific impulse of 296 seconds in a vacuum. Reaver 1 utilizes a tap-off combustion cycle, in which hot gases from the combustion chamber are routed through the turbopump turbines before being exhausted. This forgoes the need for an extra gas generator, thus decreasing engine complexity and cost. The same tap-off cycle can be found in Alphas second stage Lightning 1 engine, which is also powered by RP-1 and LOX and achieves a specific impulse of 322 seconds. To date, Reaver and Lightning are the only RP-1/LOX-fueled engines
to have utilized the tap-odd cycle in flight. The majority of Alphas construction consists of carbon-fiber composites, which help to form strong but lightweight propellant tanks and airframes. This includes the 2.2-meter diameter payload fairing, which will house the VICTUS NOX payload during launch.

Launch preparations for VICTUS NOX began in earnest in early 2023, with Firefly conducting final qualification tests of the Alpha FLTA003 first and second stages at its dedicated testing facility in Briggs, Texas. Once completed, the stages were shipped off to the launch site in California. The FLTA003 stack was rolled out to the pad at SLC-2W in late March and raised to vertical for the first time in early April as part of a dry run, in which Firefly teams mated the payload fairing to the rocket while on the launch
pad. A full-duration static fire of the first stage was then completed on April 12. Satellite imagery from June 21 shows the reappearance of the
FLTA003 vehicle at the pad at SLC-2W, sans the payload fairing presumably done as part of the run-up to launch.

The company confirmed via social media in late August it had officially entered the hot standby phase of mission readiness, and that it was waiting for the final 24-hour notice from the Space Force signaling a flight would soon be imminent. The Firefly team now stands ready for the 24-hour callup

On launch day, Firefly teams will perform the final pad checkouts starting at T-8 hours before liftoff. Once complete, the teams will power up the Alpha rocket, conduct sensor checks, and begin loading pressurized helium at T-6 hours. Propellant loading operations will begin at T-5 hours 15 minutes with RP-1 loading into both stages of Alpha, followed by the start LOX loading at T-3 hours 40 minutes. At T-20 minutes before launch, Alpha will enter
terminal count, at which point the rockets onboard computers take control of the countdown. Ignition of the four first stage Reaver 1 engines will be commanded at T-2 seconds, with liftoff taking place at T0 following the release of the hold-down clamps. The vehicle will pass through the area of maximum dynamic pressure (max Q) at approximately T+1 minute into the flight. At around T+2 minutes 30 seconds, the four first stage engines will shut down simultaneously in an event called main engine cutoff (MECO), moments before stage separation and the ignition of the Lightning 1 vacuum engine. The payload fairing will be jettisoned at approximately T+3 minutes 20 seconds, exposing the VICTUS NOX payload to space for the first time. The Lightning 1 second stage motor will continue to burn until approximately T+8 minutes
after liftoff, at which point shutdown is set to occur. VICTUS NOX is slated to be one of many missions launched by Firefly Aerospace in 2023, with
another Alpha rocket FLTA004 set to launch the ELaNa 43 CubeSat mission for NASA later in the year. Both stages for the mission have undergone testing at the companys Briggs facility in preparation for flight.

The company is also gaining customers for its launch business, having signed an agreement with defense contractor L3Harris Technologies in early September for three dedicated launches on Alpha vehicles. Each of these flights will launch from Vandenberg SLC-2W no earlier than 2026, and will also feature rapid response capability.

Firefly is also heavily focused on developing components for its Medium Launch Vehicle (MLV) a two-stage medium-lift rocket that features uprated Miranda engines and has a planned maximum payload capacity of 16,000 kg to LEO. The company anticipates conducting the first launch of MLV no earlier than 2025. In addition to launch vehicles, Firefly is also continuing to
build the Blue Ghost lunar lander, which will take NASA payloads to the surface of the Moon under the agencys Commercial Lunar Payload Services
(CLPS) initiative. The first of these missions is due to launch no earlier than 2024 atop a SpaceX Falcon 9, with the company being awarded a second mission in March for a launch in 2026.

Earlier in the week, Firefly stated that it had won a third CLPS contract award from NASA to provide radio frequency calibration services for the Lunar Surface Electromagnetic Experiment at Night (LuSEE-Night) telescope, which will be deployed on the far side of the Moon during the Blue Ghost 2 mission. LuSEE-Night will measure low-frequency radio emissions during the lunar
night, providing insight into the early history of the universe and its Dark Ages.
