Photo Essay: Behind the Scenes at the Jet Propulsion Laboratory (Open House 2010)

For one weekend each year, NASA's Jet Propulsion Laboratory in Pasadena opens its doors to the public for a massive open house. This year's theme was "Worlds Beyond," and the event took place May 15 and 16.

Special features such as a 25-foot space simulator, the actual camera that flew on the Hubble Space Telescope, 3D and infrared photos, assembly and fabrication facility tours, and gliding robots in the "Robo-Dome."
