Over the years, Japan has launched a series of Engineering Test Satellites - ETS-I (KIKU-1) to ETS-VII (KIKU-7, Orihime/Hikoboshi). Each of these addressed the technological needs of its time. ETS-VIII was launched in 2006, with the main purpose of dealing with the increasing demand for digital communications, such as mobile phones and other mobile devices. #artificial_satellite #etsviii #japan #jaxa #kiku #nippon #science #SeaGate #space #きく8号 #技術試験衛星
