Firefly Aerospace has achieved a significant milestone with the completion of its first lunar lander, Blue Ghost, which has been shipped to NASA's Jet Propulsion Laboratory (JPL) for rigorous testing. The lander will undergo a series of tests to validate its performance in space. The lander will undergo:
Vibration testing: to simulate the intense vibrations experienced during launch and ascent
Acoustic testing: to simulate the extreme sound pressure levels generated during launch
Thermal vacuum testing: to simulate the extreme temperatures and vacuum conditions of space
Electromagnetic interference and compatibility (EMI/EMC) testing: to ensure the lander's electronic systems can operate without interference in the presence of other spacecraft systems
These tests will verify the lander's structural integrity, electronic functionality, and ability to withstand the harsh conditions of space travel and lunar landing.
Blue Ghost is equipped with advanced technologies, including
Hazard avoidance and terrain relative navigation (HATRN) system: uses sensors and software to detect and avoid obstacles during descent
Regolith sampling system: collects and stores lunar surface material for scientific analysis
X-ray imager: studies the Earth's magnetosphere and lunar surface composition
GPS and Galileo navigation signal receiver: demonstrates the feasibility of using terrestrial navigation signals at lunar distances.

The lander's propulsion system consists of a hypergolic propulsion system, using a combination of fuel and oxidizer to generate thrust. The system is designed to provide precise control during descent and landing. Blue Ghost's power system includes solar panels and batteries, providing a reliable source of energy during the mission. The lander's communication system uses a high-gain antenna to transmit data back to Earth.
The company has already conducted extensive testing at its Texas headquarters and is now preparing for launch on a Falcon 9 rocket in the fourth quarter of this year.
Firefly Aerospace has also implemented innovative testing approaches, including:
Simulated moonscape testing: a one-acre test site with a simulated lunar surface, used to test the lander's HATRN system.
Drone testing: a drone was flown over the simulated moonscape to test the lander's obstacle avoidance capabilities.
Drop testing: nearly 100 drop tests were conducted to demonstrate the lander's ability to withstand the shock of landing.
The mission, part of NASA's Commercial Lunar Payload Services (CLPS) program, will carry 10 science and technology demonstration payloads and attempt to land at Mare Crisium on the near side of the moon. Firefly Aerospace is set to be the third company to attempt a lunar landing as part of the CLPS program, following Astrobotic and Intuitive Machines. SolAero by Rocket Lab is providing the solar panels to power Blue Ghost, a lunar lander developed by Firefly Aerospace to deliver ten NASA payloads to the Moon's surface. ASI by Rocket Lab is also providing the lander flight software, ground software, GN&C software, trajectory design, orbit determination, and avionics/flight software testbed integration. ASI by Rocket Lab is also hosting the backup mission operations center.
“Firefly is proud to follow in the footsteps of the Surveyor landers that were tested in the same JPL facilities,” Peter Schumacher, interim chief executive of Firefly Aerospace, said in a statement, referring to the 1960s-era NASA robotic lunar landers. “The extensive environmental testing we’ll complete at JPL combined with the robust testing we’ve already completed in house will further reduce our risk posture and set us up for a successful soft landing.”
With the completion of Blue Ghost, Firefly Aerospace is one step closer to achieving a successful soft landing on the lunar surface. The company has also received a CLPS task order for a second lunar lander mission, Blue Ghost 2, which will attempt to land on the lunar farside in 2026.
