Take an adventure through inner space and explore the farthest reaches of outer space as we go back in time to explore two of Disneyland's most popular Tomorrowland attractions. First, Adventure Thru Inner Space takes you on a atomic voyage into a molecule of a snowflake, and we look at the initial design concepts and intriguing scientific notions behind this ride from Disneyland's "New" Tomorrowland of 1967. Next, shoot through the galaxy on Space Mountain, with opening day reports, sound clips, and memories of the futuristic coaster, built in 1977 and still operating today. Also - a behind the scenes look at a restoration project at the Walt Disney Family Museum, remembering Fred MacMurray, the music of Tron, and more!
