 note = {application, As a result of the technical development of methods allowing massive photometric survey of microlensing events, microlensing has become a very unique tool of astronomy to investigate the dark matter problem, the shape of our Galaxy, and to search for extra-solar planets, especially, Earth-like planets. 1～2m class Space Telescope such as the Hands-On Universe Telescope (SHOUT); which is planning to build on the Japanese Experiment Module (JEM)/International Space Station (ISS), will open a new stage of microlensing observations not only follow-up observations of microlensing events, but also survey observations of new targets, i.e. the Galactic center, globular clusters, and nearby galaxies. The follow-up and survey observations of microlensing events using the Space Telescope will answer these questions; What is dark matter?, What kind of object is MACHO?, Is our solar system unique? and, Are we alone?.},
