Table 12.2 lists important sensors which are part of the Moon missions of the three Asian countries. Here, an attempt has been made to present them in a comparative fashion (as far as possible) in regard to their functions. However, it may be noted that the design approaches and designing agencies for all these sensors are different. Also, the characteristics of some sensors vary. Hence, only a partial comparison is possible.
