Misasa Deep Space Station
is a facility of the Japan Aerospace Exploration Agency. It is a spacecraft tracking station in Saku, Nagano (formerly in Usuda, Nagano; Usuda merged into Saku in 2005), opened in October, 1984. The main features of the station are two large beam waveguide antennas, an older 64 meter antenna and a newer 54 meter dish. Usuda was the first deep-space antenna constructed with beam-waveguide technology. Although this construction dramatically simplifies installation and maintenance of electronics, it was previously thought to offer poor noise performance. However, after the U.S. Jet Propulsion Lab (JPL) tested this antenna and found the noise performance was better than its conventional 64-meter antennas, it too switched to this method of construction for all subsequent antennas of their Deep Space Network (DSN). Because the 64 meter antenna is aging and is still in use over ten years after its designed service life, JAXA has built a new antenna nearby, the 54 meter dish of Misasa D ...

Japan Aerospace Exploration Agency
The is the Japanese national Aeronautics, air and space agency. Through the merger of three previously independent organizations, JAXA was formed on 1 October 2003. JAXA is responsible for research, technology development and launch of satellites into Geocentric orbit, orbit, and is involved in many more advanced missions such as asteroid exploration and possible human exploration of the Moon. Its motto is ''One JAXA'' and its corporate slogan is ''Explore to Realize'' (formerly ''Reaching for the skies, exploring space''). History On 1 October 2003, three organizations were merged to form the new JAXA: Japan's Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL), and National Space Development Agency of Japan (NASDA). JAXA was formed as an Independent Administrative Institution administered by the Ministry of Education, Culture, Sports, Science and Technology (MEXT) and the Ministry of Internal Affairs and Communications ...
