Kyle Galesburg was a human born on the NX-class Discovery, becoming the fourth captain of the generational crew. Discovery was found by the USS Baldwin in 2377. He was the first person to make contact with Baldwin captain Patrick Ingrum.
Baldwin's crew determined that they could escape the sandbar with Discovery in tow. Richie suggested that most of his crew stay aboard Baldwin just in case they could not keep a hold of Discovery, to which Kyle suggested that his wife, Julie Galesburg, could watch over the captain's child as well.
