DESTINY⁺ is a science and technology demonstration mission to asteroid Phaethon, the parent body of the Geminids meteor shower. It will explore the asteroid during a flyby for observations of cosmic dust, which is a source of the organic matter on Earth. In-situ analysis of interplanetary and interstellar dust will be carried out. It is planned to be launched in fiscal year 2024. Model-based development process using a bread board model of an onboard mission data processor is employed prior to system level integration test to follow the tight development schedule. Hybrid and reconfigurable computers are exploited as ground-based models to pursue digital development process. Dynamically reconfigurable devices are used as the central processing unit, and extensive simulation is performed by a hardware-in-the-loop simulator.
