摘　　要：文章应用Lambert理论对载人小行星探测的轨道进行设计。结合轨道设计的基本条件与假设,建立了基于Lambert问题的轨道模型,并进行了仿真验证,结果证明模型正确有效。采用该模型,以发射窗口在2045年编号为89136的载人探测小行星A为例,给出了轨道设计的结果,同时对不同的故障情况下任务中止轨道及其特性进行了分析,对探测器应急返回能力进行了探讨。Trajectory design is an important part of research on crewed asteroid exploration. Firstly, combined with the basic condition and postulate of trajectory design, the trajectory model was built based on the Lambert theory. The validity of the model was verified through computer simulation. The trajectory model was used for the crewed exploration to asteroid 89136, and the trajectory design results were given. Secondly, different failure modes were considered, the abort trajectory and the characteristics were analyzed, and the ability of the explorer to return to the earth in an emergency was discussed. Finally, the related conclusions were drawn.
