Firefly Aerospace has secured a $13 million subcontract from NASA’s Jet Propulsion Laboratory (JPL) to manufacture the aeroshell for the upcoming SkyFall mission to Mars. The mission, targeting a 2028 launch, will deploy three helicopters to conduct subsurface mapping and resource prospecting, utilizing advanced carbon fiber composite technology developed at the company’s Gloworks innovation lab.
Engineering the SkyFall Aeroshell for Martian Entry
The SkyFall aeroshell—comprising both a backshell and a heatshield—is designed to protect the mission’s payload during the intense conditions of launch, cruise, and Mars entry, descent, and landing (EDL). According to Firefly CTO Shea Ferring, the company will leverage its experience in building large composite structures for its Alpha and Eclipse launch vehicles, as well as its Blue Ghost lunar landers, to satisfy the mission requirements.
Manufacturing is slated for Firefly’s Rocket Ranch in Briggs, Texas. Following production, the structures will undergo rigorous structural qualification and flight acceptance testing at Firefly’s facilities. Once complete, the hardware moves to JPL for further environmental testing and final integration with the helicopter deployment system.
The “SkyFall Maneuver” represents a shift in planetary exploration. By using an entry capsule to release helicopters mid-air during descent, NASA eliminates the need for a traditional landing platform, allowing the craft to scout terrain and water ice directly.
Composite Evolution: From Ingenuity to SkyFall
The SkyFall helicopters build upon the technical foundation established by NASA’s Ingenuity Mars helicopter. Ingenuity demonstrated the viability of flight in the thin Martian atmosphere through a rotor system composed of four carbon fiber blades. According to JEC Composites, these blades spin at roughly 2,400 rpm, pairing a carbon fiber skin with a lightweight foam core, a construction method essential for generating necessary lift.
By producing these structures in-house at the Gloworks lab, Firefly aims to maintain production speed without disrupting its existing launch vehicle assembly lines.
Expanding Capacity for Lunar and Deep Space Missions
Firefly is scaling its infrastructure to support a growing portfolio of NASA contracts. The company recently doubled the size of its central Texas facilities, including an expansion of its spacecraft cleanroom. This capacity increase is intended to support an assembly line approach for multiple missions per year.
Beyond the Mars SkyFall project, Firefly is actively engaged in NASA’s Commercial Lunar Payload Services (CLPS) initiative. The company is preparing for four upcoming lunar missions and has been tasked by JPL to deliver four drones to the lunar south pole using its Elytra spacecraft for the MoonFall mission.
When evaluating space-grade materials, look for the integration of carbon fiber composites with foam cores. This combination is described by NASA and CBS News as essential to generating lift in Mars’ thin atmosphere.
Frequently Asked Questions
What is the “SkyFall Maneuver”?
It is a mid-air release technique where a descent capsule releases helicopters during the entry phase, removing the requirement for a physical landing platform on the Martian surface.
Where will the SkyFall aeroshell be manufactured?
Firefly Aerospace will develop the aeroshell at its Gloworks innovation lab and manufacture it at the company’s Rocket Ranch facility in Briggs, Texas.
What materials are used in the construction of these spacecraft structures?
Firefly utilizes carbon fiber composites, similar to the materials used in its Blue Ghost landers and Alpha launch vehicles. The rotor blades on similar heritage helicopters use a carbon fiber skin paired with a lightweight foam core to generate lift in thin atmospheres.
What is the goal of the SkyFall mission?
The mission aims to perform science, demonstrate airborne subsurface mapping, and prospect for resources like water ice, effectively scouting terrain to support future U.S. astronaut missions on Mars.
