NanoFF B, part of a formation-flying technology demonstration pair testing coordinated multi-satellite operations in low Earth orbit. Pairs like this typically exist to test coordinated operations between two spacecraft — comparative sensor readings, formation flying, or simply redundancy — even when the specific technical goal hasn't been widely publicized.
