Apollo 13 Guidance, Navigation, and Control Challenges
TL;DR: In the Apollo 13 mission, guidance, navigation, and control (GNC) challenges were the reestablishment of attitude control after the oxygen tank incident, re-establishment of a free return trajectory, resolution of a ground tracking conflict between the LM and the Saturn V S-IVB stage, maneuvering to burn attitudes, attitude control during burns, and performing manual GNC tasks with most vehicle systems powered down as discussed by the authors.

Apollo looking forward: Crew task challenges
TL;DR: In this paper, the authors describe the major tasks that must be performed by either automation or people (on or off-board) for the next generation lunar lander, which serve as case studies for future landing challenges.

Computer-controlled steering of the Apollo spacecraft.
R. H. Battin,F. H. Martin +1 more
TL;DR: Apollo spacecraft powered maneuvering controlled by digital computer as central element in guidance, navigation and control system as discussed by the authors was used for the Apollo spacecraft propulsion and maneuvering control system in the early 1990s.
Explicit and unified methods of spacecraft guidance applied to a lunar mission.
TL;DR: Unified lunar spacecraft guidance of major and minor maneuvers during accelerated and coasting flight is discussed in this article, where the authors propose a unified approach for the guidance of Moon spacecraft during a mission to the Moon.
