Currently a significant portion of earth observation by nistar which resides on the dscovr spacecraft is contaminated by light from the moon

The National Aeronautics and Space Administration (NASA) awarded a $106,992 project grant to L-1 Standards and Technology, Inc. through the Science (CFDA 43.001) federal grant program. The grant funds services to reduce contamination of earth observation data collected by the National Institute of Standards and Technology Advanced Radiometer (NISTAR) instrument onboard the Deep Space Climate Observatory (DSCOVR) spacecraft. Specifically, L-1 Standards and Technology will address the issue of moonlight entering NISTAR's field-of-regard twice monthly, adding an unknown amount of light and compromising a significant portion of NISTAR's earth observation capabilities from the DSCOVR platform. By the completion date of December 16, 2021, L-1 Standards and Technology is expected to deliver services to mitigate moonlight contamination of NISTAR instrumentation, thereby enhancing the quality and scientific value of earth observation data gathered through the DSCOVR mission.
