Abstract: In order to meet on going requirement of information for exploration to the earth and planet, space remote sensor must be manufactured with high spatial resolution, high spectrum resolution, high radiation resolution and super imagine quality while keeping light weight, besides that, the adaptability of space remote sensor to the variety rigor launching and space vacuum thermal environment must be taken into consideration. It is depicted summarily that the present state of environment adaptability design and the influence of mechanics and vacuum thermal environment on the performance of space remote sensor, and probe into the mechanism of environment effect, and the key points of environment adaptability design. The environment adaptability factors must be taken into account as a whole in the earlier design phase. It is pointed out that mass character; dynamical behavior and thermal optics character of space optical remote sensor are the most important factors to be considered in the course of iteration of design and analysis. During the production engineering stage, environment adaptability test should be carried out for assessing practice dynamical behavior and thermal optics character of product, and verify the validity of performance of space optical remote sensor for the sake of insuring sensor’s adaptability against variety rigor environment. The appraise method of environment adaptability design and the related test content are also described in this paper.
