NASA’s Jet Propulsion Laboratory, Pasadena, California, invites the public to its annual Open House on October 10-11, 2015. The event is free of charge and takes visitors on a “ride” through the wonders of space. Highlights include a life-size model of Mars Science Laboratory, demonstrations from numerous space missions; JPL’s machine shop, where robotic spacecraft parts are built; and the Microdevices Lab, where engineers and scientists use tiny technology to revolutionize space exploration.
