Artist's impression of the Euclid spacecraft, a dark energy and dark matter mission planned for launch in 2020.
Euclid is a European Space Agency mission with science instruments and data analysis provided by the Euclid consortium with important participation from NASA. NASA's Euclid Project Office is based at JPL. JPL will contribute the infrared flight detectors for one of Euclid's two science instruments. NASA Goddard will assist with infrared detector characterization and will perform detailed testing on flight detectors prior to delivery. Three U.S. science teams, led by JPL, Goddard and the Infrared Processing and Analysis Center at Caltech, will contribute to science planning and data analysis. Caltech manages JPL for NASA.
