In the early 1980s, NASA astronaut Sally Ride became the first American woman to travel to space. Ride faced increased scrutiny and public attention as a result of her groundbreaking mission, but throughout her life, she kept one aspect of her identity a secret. A new documentary, "Sally," tells the complex story of Sally Ride, including interviews with Tam O’Shaughnessy, Sally’s life partner for 27 years. Director Cristina Costantini discusses "Sally," which premieres on National Geographic on June 16.
