A view of a section of the JPSS-4 satellite, featuring the integrated Libera instrument. The spacecraft and its components are heavily covered in bright golden-orange thermal insulation. Several protruding parts are wrapped in white protective covers, one of which features bold red text reading "Remove before flight." Bundles of blue and white cables hang loosely beneath the satellite body. The background shows a softly blurred cleanroom setting with work chairs, tables, and a black-and-yellow caution tape.
