Euclid, a planned mission to investigate the profound cosmic mysteries of dark matter and dark energy, has passed its preliminary design review. This clears the way for construction to begin.

Euclid is a European Space Agency mission with important contributions from NASA, including infrared detectors for one instrument and science and data analysis.

Euclid is designed to give us important new insights into the "dark side" of the universe -- namely dark matter and dark energy, both thought to be key components of our cosmos.

Euclid is a European Space Agency mission scheduled for launch in 2020. The Euclid consortium, with important participation from NASA, will provide science instruments and data and science analysis. NASA's Euclid Project Office is based at JPL. JPL will provide the infrared flight detectors for one of Euclid's two science instruments. NASA Goddard will perform detailed testing on flight detectors prior to delivery. The Euclid NASA Science Center is based at the Infrared Processing and Analysis Center (IPAC) at the California Institute of Technology in Pasadena, California. It will support all US investigators, including three teams selected by NASA. Caltech manages JPL for NASA.
