In 1990, NASA launched the historic mission which put into orbit the Hubble Space Telescope. The orbiting observatory has revolutionized astronomy and allowed us to peer deeper than ever before into the Universe. We hear from astronaut, Kathryn Sullivan. Plus, China's cure for malaria, the "Red Scare" in Hollywood in the 1940s and 50s, and a pioneering sexual harassment case at the US Supreme Court.
