Guardians

The Ram Tah Mission

The Ram Tah mission is available when you dock at Felice Dock in the Meene system, and involves you scanning ancient obelisks at various different Guardian sights for a nice hefty 101m Cr payout.

Canonn Research provide an excellent overview of the mission requirements, while a more detailed missions guide can be found at the Frontier Forums.

Down to Earth Astronomy also has an excellent YouTube guide on the missions:
