Congresswoman Gabrielle Giffords and her husband, Navy combat veteran and retired NASA astronaut Capt. Mark Kelly, have dedicated their lives to service. The youngest woman ever elected to the Arizona State Senate, Rep. Giffords spent more than a decade representing her community first in the state legislature and then in Congress. As a naval aviator, Capt. Kelly made two tours of duty and flew 39 combat missions, before becoming a NASA astronaut – flying four missions and spending more than 50 days in space.
