Founded by Caltech researchers, NASA's Jet Propulsion Laboratory (JPL) is the leading center for exploring the solar system and more distant expanses that humans cannot yet reach.
Working together, scientists and engineers on the Caltech campus and at JPL lead missions in planetary exploration, Earth science, and space-based astronomy. Their spacecraft and telescopes probe the farthest reaches of our solar system and discover worlds beyond, while also observing our home planet to provide crucial insights on climate and to assist in disaster recovery. Meanwhile, technological innovations that originated at JPL continue to transform life here on Earth. Indoor Hot Tub
