A service satellite with a laser system emits a focused laser beam to the target to generate laser ablation. The orbit and attitude (including rotational status) of the target can be changed sufficiently by the reaction force of the plasma/gas ejected from the target surface. Ground experiments, including high-precision measurements of the ablation reaction and a feasibility study of the service satellite, were performed in collaboration with JSAT and RIKEN. Our conceptual study shows that our service can deorbit a 150 kg target at an altitude of several hundred kilometers by means of a small laser satellite (150 kg) and a 200 W class Payload Power. We found four advantages of the laser ablation method over conventional active methods for the removal of nonfunctional satellites: (1) minimal risk of collision, since the laser satellite does not require any physical contact with the target; a high-intensity pulsed laser can ablate surface material of the target from a distance; (2) detumbling is also possible during the operation; (3) the service satellite is not required to carry additional fuel for the target because the required thrust is generated from vaporization and ionization of the target material; (4) additional specifications (e.g. a handle to capture ) for customer satellites are not necessary. In this presentation, we present the concept and provisional schedule of our EOL deorbit service.","subitem_description_type":"Other"}]},"item_4_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
