Utilizing Space Through Satellites

Satellites offer a wide variety of valuable services. These include communications and weather observation, which are essential to modern life, as well as astronomical observation and space development. Japanese satellites now in orbit are performing missions in a wide range of areas. For example, they have been playing an important role in assessing and analyzing abnormal weather patterns. For the purpose of planetary exploration, plans are under way for sending probes to the Moon and Mars.
