Design of contingency point return trajectory in the lunar orbit insertion phase for crewed lunar exploration missions

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2022
To satisfy the requirement of contingency rescue in the lunar orbit insertion phase for crewed lunar exploration missions, this paper designs the contingency point return trajectory. First, according to different failure situations of the main propulsion

Lunar Pit Morphology: Implications for Exploration

Journal of Geophysical Research: Planets, 2022
Lunar pits are small (∼10–300 m wide) collapse features with vertical walls and sometimes overhangs. We have identified almost 300 pits, mostly in ponds of cooled impact melt inside large craters younger than ∼1 billion years.
