The Copernicus Sentinel-2C satellite is tasked with orbiting Earth and take images of our planet.
But roughly once a month, the satellite will roll sideways to image the Moon instead of Earth. The Moon’s well-known and stable light intensity allows us to detect and correct even the smallest changes in the instrument’s performance, which can occur due to aging, such as optical coating degradation or detector drifts.
