Mission to Hibernia
"Who can I have?"
The canyon was a little far for them to ride all the way there from the ship, so they'd need to be dropped off short of the target, unless they could afford several days just to make their approach.
The skill to control the bikes would be necessary, as well as any other complementary skills for the mission - stealth, survival, camouflage, communications, navigation, and climbing for example. Combat skills would be welcomed, but not a high priority given the task was simply to go take a look and report back.
