Firefly Aerospace Completes Preliminary Design Review for NASA MoonFall Mission

The review confirmed Elytra’s design meets mission requirements, with final design review still ahead of hardware production and assembly.

Rhea-AI Summary

Firefly Aerospace (Nasdaq: FLY) completed the preliminary design review for its Elytra spacecraft for NASA’s MoonFall mission to the lunar south pole.

The review confirmed that Elytra’s design meets mission requirements. Firefly will now work toward the final critical design review before hardware production and assembly. The milestone came less than four months after contract award. MoonFall is targeted to be ready for launch by late 2028. NASA’s Jet Propulsion Laboratory is building the drones and managing the mission, while NASA will source the launch vehicle. Elytra will carry the drones from Earth orbit to lunar orbit and deploy them above the south pole.

2 terms

preliminary design review technical

"completed the preliminary design review (PDR) for its Elytra spacecraft"

Preliminary design review is a formal assessment early in the development of a product, system, or project where engineers present initial designs to confirm they meet key requirements and can proceed to detailed work. For investors, it matters because passing this milestone reduces technical and schedule risk—like getting approval for a building’s blueprints before construction—making it more likely the project will stay on time and budget and improving prospects for future funding or revenue.

critical design review technical

"toward the spacecraft’s final critical design review (CDR)"

A critical design review (CDR) is a formal, high‑level assessment where engineers and independent reviewers confirm a product or system’s detailed plans meet required performance, safety and regulatory needs before committing to full-scale production or implementation. For investors it signals reduced technical and schedule risk—like approving a final blueprint before construction—so passing a CDR often increases confidence in a project’s timeline, budget predictability and likelihood of commercial success.

Milestone moves Firefly's Elytra spacecraft toward final design and hardware production to deliver NASA JPL drones above the lunar south pole

CEDAR PARK, Texas, Oct. 21, 2026 (GLOBE NEWSWIRE) -- Firefly Aerospace (Nasdaq: FLY), a market leading space and defense technology company, today announced it completed the preliminary design review (PDR) for its Elytra spacecraft that will deliver drones built by NASA’s Jet Propulsion Laboratory (JPL) to the Moon's south pole for the agency’s MoonFall mission.

Firefly’s PDR, including members from NASA and JPL, conducted a thorough review of Elytra’s structural, thermal, propulsion, avionics, trajectory design, guidance and navigation, communications and control systems as well as the spacecraft's qualification and environmental test plans. The review confirmed Elytra’s design meets the mission requirements, and Firefly will now begin working toward the spacecraft’s final critical design review (CDR) ahead of hardware production and assembly.

"Completing PDR less than four months after contract award is a testament to the speed and rigor Firefly brings to every mission," said Ray Allensworth, Vice President of Spacecraft at Firefly Aerospace. "As NASA accelerates its Moon Base Program, we're rapidly scaling spacecraft production to support MoonFall and a growing manifest of lunar surface missions, utilizing proven systems, hardware, and operations from our first successful Blue Ghost mission."

Targeted to be ready for launch by late 2028, MoonFall is part of the first phase of the Moon Base, a long-term lunar exploration and infrastructure initiative designed to enable sustained human presence and expanded scientific and commercial activity at the lunar south pole.

JPL is building the drones and managing the mission for NASA, which will source the launch vehicle for MoonFall. After launching, Firefly's Elytra spacecraft will transit from Earth orbit to lunar orbit and deploy the drones above the Moon's south pole. The MoonFall drones will then use their high-definition optical cameras and instruments to survey the south pole terrain and map safe landing spots and resources to support future human missions.

About Firefly Aerospace
Firefly Aerospace is a space and defense technology company on a mission to reliably and repeatedly launch, land, and operate space systems from Earth to the Moon and beyond. As the partner of choice for responsive space missions, Firefly is the first commercial company to launch a satellite to orbit with approximately 24-hour notice and the first to achieve a successful landing on the Moon. Established in 2017, Firefly’s engineering, manufacturing, and test facilities are co-located in central Texas to enable rapid innovation and vertical integration for the company’s small- to medium-lift launch vehicles, lunar landers, and orbital vehicles.
