Free Admission Saturday at The California Science Center - see INFO below. Air Gallery explores how the pursuit to master the sky involves tradeoffs among four forces of flight lift, thrust, drag and weight that affect every aircraft ever flown, whether it flies high, low, fast or slow. The Air Gallery will have three primary thematic areas: Taking Wing, At Home in the Sky and Pushing the Limits and will include approximately 20 aircraft on display. From a replica of the Wright Brothers 1902 Glider to modern supersonic jet fighters built from lightweight composite materials, the gallery will show the evolution of flight design through science and engineering concepts. Space Gallery rendering Samuel Oschin Air and Space Center Space Gallery examines how the machines we build to explore space extend our reach and help transform our ideas about the universe, whether its with powerful telescopes that look at distant stars and galaxies, robots that go places and collect data, or spaceships designed to transport humans and protect them from lethal environments. The Space Gallerys three primary thematic areas include Lift Off, Robotic Spacecraft and Telescopes and Humans in Space. The Science Centers collection includes examples of spacecraft from every stage of the U.S. manned space program including the Apollo-Soyuz Command Module (ASTP), Mercury MR-2 and Gemini 11 space capsules, along with an array of engineering models of planetary probes, telescopes and Earth observation spacecraft.
