JPL is a federally funded research and development facility managed by the California Institute of Technology for the National Aeronautics and Space Administration. From the roar of pioneering Space Age rockets to the soft whir of servos on 21st century robot explorers on Mars, the Jet Propulsion Laboratory’s spacecraft have blazed the trail to the planets and the universe beyond for more than 50 years. Meeting the challenges of robotic space exploration has resulted in new knowledge that has kept JPL a world leader in science and technology. The tools JPL has developed for space exploration have also proved invaluable in providing new insights and discoveries in studies of Earth, its atmosphere, climate, oceans, geology, energy and the biosphere. The ongoing invention of ever more-sensitive robotic space missions and enabled by space sensors has also resulted in a myriad of technology applications widely used for medical, industrial and commercial uses on Earth.
