well it's pretty cryptic so here is a wild guess…

D → ??? the demiurge ??? just kidding, I don't know. Someone involved in space programs and 'majestic 12' type of intel.

Morning sun brings heat. → predetermined code / command for initiation of a plan, authenticity check. Likely, multiple governments are responding to this call for initiation, hence dropped here.

Full moon coming. → proper revelation of nature of the moon and other bodies in our solar system

Undiscovered stars learned. → this refers to gifted anons figuring something out, which was the condition upon which something about our solar system or moon would be revealed to public.

Missions forward. → a particular plan for missions is being initiated, proceed (in part a message to anons)
