Carnelian minefield

In 2363, Captain Jean-Luc Picard and his ship were part of a rescue mission. During this mission, Picard witnessed Natasha Yar risk her life to rescue a colonist from a Carnelian minefield. Picard was so impressed with Yar's bravery that he recruited her for duty aboard the USS Enterprise (NCC-1701-D) upon its launch in 2364.
