Alejandro Rodriguez Perez and Joe Thomes, members of the fiber optic & photonic team, configure the Ocean Color Instrument (OCI) Engineering Test Unit (ETU) Shortwave Infrared (SWIR) Detector Asembly and Multi-lens Array (MLA) fibers for thermal testing. OCI is a highly advanced optical spectrometer that will be used to measure properties of light over portions of the electromagnetic spectrum. It will enable continuous measurement of light at finer wavelength resolution than previous NASA satellite sensors, extending key system ocean color data records for climate studies. OCI is PACE's (Plankton, Aerosol, Cloud, ocean Ecosystem) primary sensor built at Goddard Space Flight Center in Greenbelt, MD.

This is the James Webb Space Telescope ETU (engineering test unit) primary mirror segment returning to the cleanroom at NASA Goddard after undergoing some tests at our new Calibration, Integration, and Alignment Facility (CIAF).
