Actually, to trigger the side-quest with the two dead explorers, you have to talk to the woman in the salvagers' camp that sells lightsaber crystals (don't recall her name...). If you choose the right conversation tree the first time you talk to her, she'll explain about the two lost salvagers and how she "just wants to give them a proper burial".
There's a bug, however. If you talk to her again without having triggered the quest first, she'll assume she already gave it to you and ask if you found the dead salvagers.
Jorran doesn't really have anything to do with this quest.
