Firefly Aerospace Blue Ghost, commonly referred to as Blue Ghost, represents a series of lunar lander vehicles engineered by the American aerospace firm Firefly Aerospace. These landers are specifically designed and operated by Firefly to transport small-scale payloads onto the lunar surface. The inaugural Blue Ghost mission was launched in January 2025 and achieved a successful Moon landing on March 2, 2025. The name of the landers is inspired by the firefly species Phausis reticulata, also known as blue ghosts.

Overview

As the main contractor, Firefly Aerospace oversees the entire lunar delivery process using Blue Ghost landers, encompassing payload integration, launch from Earth, lunar touchdown, and overall mission management. The company's facility in Cedar Park, Texas functions as both the payload integration hub and mission operations headquarters. This site includes a 50,000 square-foot spacecraft production area equipped with two mission control centers and an ISO-8 cleanroom environment, supporting multiple lander projects simultaneously.

The Blue Ghost spacecraft features a flexible design suitable for a range of cislunar missions and can be modified to undertake advanced operations such as surviving the lunar night, enabling surface mobility, and returning samples. It is compatible with various launch service providers. Firefly emphasizes its unique capability to manufacture and test the entire Blue Ghost structure internally, distinguishing it from other Commercial Lunar Payload Services (CLPS) landers.

NASA selected Firefly on November 29, 2018, to receive task orders under the CLPS program. By August 2025, Firefly had been awarded four lunar landing contracts by NASA.

Design

During transit, lunar orbit, and surface activities, Blue Ghost delivers essential data transmission, power supply, and thermal regulation. Its main propulsion system is a LEROS 4-ET bipropellant engine supplied by Nammo UK, which utilizes MON and hydrazine propellants. This engine generates thrust exceeding 1,000 newtons for critical maneuvers such as lunar orbit insertion and powered descent.

For attitude control and soft landing capabilities, the lander employs eight Spectre thrusters in its reaction control system. It is equipped with four carbon composite landing legs featuring contact sensors that automatically shut down the engines upon ground contact. Electrical power is provided by solar panels capable of producing up to 400 watts. Communication with Firefly's mission operations center is maintained through one X-band antenna alongside three S-band antennas.

Blue Ghost M1

On February 4, 2021, NASA awarded Firefly a CLPS contract valued at US$93.3 million to deliver ten scientific experiments and technology demonstrations to the Moon. Subsequently, on May 20, 2021, Firefly chose Falcon 9 as the launch vehicle for this mission. Blue Ghost Mission 1 successfully touched down on March 2, 2025, in the Mare Crisium region.

The mission focused on Mare Crisium, a prominent basin observable from Earth. Scientific instruments collected data regarding lunar soil characteristics, geophysical properties, and interactions between solar wind particles and Earth's magnetic field—information vital for future crewed lunar exploration efforts. Since Firefly's own Alpha rocket did not meet the payload capacity or volume requirements for Blue Ghost missions, upcoming flights are planned to utilize Firefly's forthcoming MLV launch vehicle.

Payloads

The suite of payloads, totaling approximately , comprises:

Regolith Adherence Characterization (RAC): Investigates lunar dust adhesion properties during landing and surface activities.
Next Generation Lunar Retroreflectors (NGLR): Facilitates high-precision Earth-Moon distance tracking and lunar interior analysis.
Lunar Environment Heliospheric X-ray Imager (LEXI): Captures images of interactions between Earth's magnetosphere and solar wind particles.
Reconfigurable Radiation Tolerant Computer System (RadPC): Tests radiation-hardened computing hardware suitable for lunar environments.
Lunar Magnetotelluric Sounder (LMS): Examines electric and magnetic fields to assess the Moon’s mantle composition.
Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER): Measures heat flow by drilling into the lunar regolith.
Lunar PlanetVac (LPV): Gathers lunar soil samples for scientific examination or potential Earth return.
Stereo Cameras for Lunar Plume Surface Studies (SCALPSS 1.1): Records imagery of surface disturbances caused by lander engine plumes to aid understanding of landing dynamics.
AstroVault: A robust lunar archive preserving human cultural artifacts, art, and scientific data for posterity.
Electrodynamic Dust Shield (EDS): Employs electric fields to clear dust from surfaces, applicable to space technology operations.
Lunar GNSS Receiver Experiment (LuGRE): Evaluates reception of GPS and Galileo satellite signals at lunar distances.

Blue Ghost M2

The second mission in the Blue Ghost series is planned for a 2026 launch. It will deploy both the lander and the Lunar Pathfinder spacecraft into lunar orbit using Firefly Aerospace's Elytra orbital transfer vehicle. NASA, via JPL, has sponsored a User Terminal payload located on the lander's upper deck to activate the Lunar Pathfinder satellite. Additionally, Firefly intends to deliver the Rashid 2 rover to the Moon’s surface during this mission.

Blue Ghost M3

Targeted for launch in 2028, Blue Ghost M3 will feature a rover deployment near the Mons Gruithuisen Gamma dome on the Moon. The lander and rover will carry instruments developed under the Lunar-VISE initiative at the University of Central Florida, expanding scientific exploration capabilities.

Blue Ghost M4

Announced in July 2025 with a planned launch in 2029, Blue Ghost M4 will touch down on the rim of Haworth Crater close to the lunar south pole. This mission will transport two rovers and three scientific instruments to the surface. One rover, MoonRanger, was originally designated for a Masten Space Systems mission, while a second rover will be supplied by Canadian company Canadensys Aerospace.

Blue Ghost M5

In September 2025, Firefly disclosed to the SEC that a "proprietary commercial client" had chosen Blue Ghost for an additional exclusive mission.

Funding

The 2017 Space Policy Directive 1 set in motion efforts to send NASA astronauts back to the Moon. By 2018, NASA invited nine firms, among them Firefly Aerospace, to compete for contracts under the Commercial Lunar Payload Services (CLPS) initiative, a crucial element of the Artemis program designed to develop a sustainable crewed lunar outpost.

In 2021, Firefly was awarded a NASA contract worth US$93 million to perform lunar landings as part of Artemis.
