We all think of astronauts as invincible explorers whose métier automatically ranks them as heroes. Despite passing his health screening, Lieutenant Colonel Michael "Rich" Clifford, who served in missions aboard the Discovery, Endeavour and Atlantis space shuttles, knew that something was wrong — a secret he, his doctor and a handful of NASA officials guarded for many, many years.

A film by Houstonian Zach Jankovic tells Clifford's story. The 30-minute documentary, titled The Astronaut's Secret, reveals the 62-year-old astronaut's battle with Parkinson's disease. For Clifford, the film is his opportunity to help change the public's perception of a condition that's generally misunderstood.

President George H.. Bush and Barbara Bush, as honorary chairs of this screening, are scheduled to be present. The event benefits the Houston Area Parkinson Society and Parkinson's Disease Center and Movement Disorders Clinic, Baylor College of Medicine, Department of Neurology.
