Flying Laptop is a German small satellite launched on 14 July 2017 on a Soyuz-2.1a rocket from Baikonur, Kazakhstan. It carries the OSIRISv1 laser communications experiment. The 110-kg spacecraft operates in a 600-kilometer Sun-synchronous orbit with a 97.6-degree inclination. It is part of the Stuttgart Small Satellite Program run by the German Space Agency. Optical data links have been tested with ground stations in Japan, Europe, and Canada, reaching up to 200 Mbit/s from space to ground. OSIRISv1 uses two fixed lasers aimed at ground stations, controlled by pointing the whole satellite with four reaction wheels. The wheels can be desaturated by three internal magnetorquers. Flying Laptop also carries a de-orbit device called DOM2500, developed by Tohoku University and manufactured by Nakashimada Engineering Works, which will unfurl a sail to increase atmospheric drag at the end of the mission.
