Space Station Live: Why Fruit Flies

NASA Commentator Brandi Dean talks with Dr. Vic Cooley, the lead increment scientist for the International Space Station’s Expeditions 41 and 42, about the Fruit Fly Lab experiment that arrived on the station on the most recent Dragon cargo ship. The fruit flies are an animal model for the human immune system for scientists assessing biological impacts of space flight on human beings to prepare for future long-duration exploration missions to deep space.
