In a powerful tribute to both scientific achievement and personal courage, Cristina Costantini’s Sloan-supported documentary SALLY, which made its world premiere at the 2025 Sundance Film Festival, is now available to stream on Hulu. The National Geographic Documentary, which explores the life of astronaut Sally Ride—the first American woman in space—delves beyond her public persona to reveal a deeply personal story of love, identity, and sacrifice.
SALLY was honored with the prestigious 2025 Alfred P. Sloan Feature Film Prize at Sundance, a recognition awarded to outstanding films that focus on science or technology or depict scientists as central characters. The prize includes a $25,000 cash award, and was presented to Costantini during a celebratory reception in Park City.
Sally Ride is celebrated for breaking barriers in science and space exploration but SALLY uncovers another side of her life: her 27-year relationship with her life partner, Tam O’Shaughnessy. The film sensitively portrays the challenges Ride faced in keeping her relationship private during a time when being openly queer could have jeopardized her career and legacy.
The Pride Month premiere is apt, as SALLY is more than a biographical documentary—it’s a celebration of authenticity, resilience, and the quiet strength of queer pioneers in STEM.
