A research paper co-authored by five UoA faculty members and one UoA master's student affiliated with the Aizu Center for Space and Informatics (ARC-Space(※1)) was published in the digital edition of the world-renowned British academic journal Nature(※2) on Monday, March 16, 2020. This paper summarizes research achievement such as the capturing of a full rotation's worth of high-resolution thermal images of the asteroid Ryugu by Hayabusa 2, a world first, and discovering that the surface consists of porous boulders and fragments.
This is the first time a research paper co-authored by a UoA student has been published in Nature. The student, SUKO Kentaro, a second-year master's student supervised by Professor Demura, was in charge of the development and operation of the HEAT software for calibration and temperature conversion for the Thermal InfraRed Imager (TIR), as well as temperature calibration and conversion based on the ground test data.
In addition to participating in the Hayabusa 2 project, ARC-Space faculty members and students also developed and provided the HEAT software and systems such as the 3D geographical information system for asteroids (AiGIS)(※3).
