Blue Ghost's main mission will be research. It will hang out in Earth's orbit for 25 days taking measurements and waiting for the right time to fling itself to the moon. After four days in transit, Blue Ghost will spend 16 days in lunar orbit collecting more data before descending to Mare Crisium, one of the largest basins on the moon.

Blue Ghost’s Moon mission, launched by SpaceX, is set to revolutionize lunar exploration and offer Earth valuable lessons from space. At 1:11 a.m. EST on SpaceX launched its Falcon 9 rocket carrying Firefly Aerospace’s Blue Ghost lunar lander.

The two robotic lunar landers —one from Firefly Aerospace based near Austin, Texas, and another from the Japanese space company ispace—will use their own small engines for the final maneuvers required to enter orbit around the Moon in the coming months.
