DEBUT (Deployable Boom and Umbrella Test) was a Japanese technology satellite launched by the same 2-stage H-1 rocket that launched MOS-1B. It carried a retractible 1.46-m boom and 24-panel aerodynamic umbrella to verify deployment operations in space. Such umbrellas may one day be used to lower orbits of geostationary satellite or as aerodynamic braking mechanisms for lunar/planetary missions. Developed by the National Aerospace Laboratory, DEBUT was separated from the second stage 60 m, 21 sec after liftoff. The national name for this satellite was Orizuru meaning "folded paper crane" in Japanese.
