Muses-B
In 1996 with the help of ISAS' new M-5 launch vehicle, the institute plans to expand its astrophysical studies into the radio spectrum with the Muses-B spacecraft. The objective of the new VLBI Space Observatory Program (VSOP) is to obtain quality images of both highly energetic and weak radio sources at frequencies of 1.6, 5, and 22 GHz. The 800-kg spacecraft will deploy a 8-m diameter, gold-plated mesh antenna once it reaches an operational orbit of 1,000 km by 20,000 km. The primary contractors developing Muses-B are Mitsubishi Electric Company and Heavy Industries, Nippon Electric Company, Sumitomo Heavy Industries, and Toshiba Corporation (References 265, 273-274).
