It seems Professor Palin is requesting the collection of Alien items. All you need to do is dock at Obsidian Orbital and you will be given the mission.
As this is a chained mission set, the rewards vary. It depends on your highest Combat, Trade or Exploration rank. There are three chained missions, each increasing in value. Once you have handed in all three, you can start the chain again by re-docking at Obsidian Orbital.
The closest Unknown Structure to Merope is :
PLEIADES SECTOR OD-S B4-1 2 A

Once you hand in the alien items at which ever base is listed in the port of the transaction log entry on your navigation panel, head back out to Obsidian Orbital and you will receive another mission.
