Outer space is in a special environment　that is significantly different from Earth in many ways. One example is the microgravity environment. Microgravity is an excellent environment to observe how micro-level things work because the phenomena, such as convection and subsidence are unlikely to occur.
Space experiments are expected not only to study the effects of outer space environment on humans in order to expand space activities, but also to bring benefits to people living Earth.

technology to do microscopic observation just by placing a sample on a chip of semiconductor, which arranges light-sensing elements in a fine mesh shape.
