Along with the points made by other comments, this mission will bring 10 cubesats that will be released and will orbit the moon for an extended period of time. They will map the surface and scan for resources, giving intel for future missions.

Local resources on the moon allow us to plan our payload, and may present opportunity for interplanetary missions if the resources are abundant enough. Image being able to mine and create rocket fuel on the moon to use on trips to mars, Venus, etc.
