Summary
[edit]DescriptionOCI Star Tracker Integration (GSFC 20221114 PACE 080291).jpeg |
English: Engineer, Marton Sharpe, and mechanical technicians, Alexander Schaeffer and Eric Norris, install the Star Tracker to the Ocean Color Instrument (OCI) prior to integration to the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) spacecraft. The Star Tracker is a specially designed sextant to measure the angle between different celestial bodies in relation to each other or the horizon. This is important not just for navigation but for providing better images and science data. 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 primary sensor built at Goddard Space Flight Center in Greenbelt, MD. |
