“…The abort then is carried out at the reference point automatically. In this case, the primary navigation system is not necessary during the period from failure occurring to abort execution [19].…”

“…Goodman [18] summarized the guidance, navigation and control challenge of the Apollo 13. Callas [19] assumed failures to necessitate abort at various points along the lunar trajectory, and then predicted the states of the next two reference points after an observation finished. If an emergency occurs, the abort trajectory at the nearest reference point and the time of flight to reach that point can be calculated by using the predicted states of the reference point.…”

Abort trajectory is a passage that ensures the astronauts to return safely to the earth when an emergency occurs. Firstly, the essential elements of mission abort are analyzed entirely based on summarizing the existing studies. Then, abort trajectory requirement and rational selection for different flight phases of typical manned lunar mission are discussed specifically. Considering a trade-off between the two primary constrains of an abort, the return time of flight and energy requirement, a general optimizing method for mission abort is proposed. Finally, some suggestions are given for China's future manned lunar landing mission. manned lunar landing, mission abort, trajectory design, free return trajectory Citation:
