For ASTROD I program, the distance from the Sun is from 0.5 AU to 1.04 AU. Without shielding of Earth’s magnetosphere, the satellite will be exposed directly to cosmic rays, solar event particle and solar wind particle and the longevity and reliability of some enable techniques for ASTROD I, such as capacitive sensors, thrusters, lasers and optics will be influenced. In this paper, the space environments and their effect for ASTROD I is analyzed. It also proposed the study of interplanetary environment as a science object for ASTROD I and a light radiation monitor will be onboard.
