Firefly Aerospace’s Blue Ghost moon lander made history on March 2 by achieving a soft landing on the moon. It became just the second private spacecraft to touch down on the lunar surface. This mission is quite significant as it carries 10 NASA science instruments, including one called SCALPSS, which stands for Stereo Cameras for Lunar-Plume Surface Studies.
SCALPSS had an important job. It documented how the lander’s thruster plumes interacted with the moondust during landing. Just days after the mission, we learned that it successfully captured stunning footage of Blue Ghost’s descent into the Mare Crisium, a large volcanic basin on the moon’s near side.
Rob Maddock, the project manager for SCALPSS, shared that the cameras collected over 3,000 images during the landing. He explained, “The data is vital to reducing risk in the design and operation of future lunar landers.” This information is crucial as NASA prepares to return humans to the moon through its Artemis program.
The footage shows that as Blue Ghost descended from about 91 feet (28 meters), it began stirring up the lunar surface at roughly 49 feet (15 meters). The interaction between the thrust plumes and the moon’s regolith—its dust and soil—became more complex as the lander got closer to the surface.
Currently, SCALPSS is operational on the moon and continues to send back valuable data. Its insights will help NASA understand the lunar environment better, especially as they plan missions for future lunar bases, particularly near the south pole.
Other experiments on board Blue Ghost are also making progress. The Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (or LISTER) is successfully drilling into the moon to measure heat flow. Meanwhile, the Lunar PlanetVac is demonstrating a unique technique for collecting lunar soil using pressurized nitrogen, which could be used in future missions to Mars.
The mission won’t last forever, though. The solar-powered lander is expected to lose power soon after sunset on March 16. Interestingly, the mission team plans to capture the upcoming total lunar eclipse, giving us a unique glimpse of this beautiful celestial event as the mission comes to a close.
As excitement grows around lunar exploration, it’s clear that efforts like those of Firefly Aerospace are paving the way for future space missions. The increasing involvement of private companies in space exploration is changing how we look at the moon and beyond, providing new opportunities for discovery and innovation.
