## Why It Matters
Taiyo is significant as a named research satellite launched in the mid-1970s under the designation Solar Radiation and Thermospheric Satellite (SRATS). Its name and aliases indicate its association with studies of solar radiation and the thermosphere, placing it within the cohort of satellites devoted to upper-atmosphere and space-environment research. The satellite’s 1975 launch from Uchinoura Space Center on an M-3C vehicle situates it within that era’s national space efforts and launcher technology. Cataloguing in international systems (COSPAR 1975-014A, SCN 07671) and registration in knowledge services (Google Knowledge Graph, Wolfram) ensure that Taiyo remains traceable in historical and technical records. For researchers, historians, and data curators, Taiyo provides a clear reference point for 1970s research-satellite programs and for studies that rely on accurate launch, catalog, and identifier information.
