... the feasibility of high-latitude landings with acceptable entry range. Design/methodology/approach – Free return trajectories satisfying all basic constraints were generated directly by a high-fidelity model with multiple differential corrections. Suitable initial assumptions, control parameters...

... presented here are limited to a single impulsive maneuver. Findings The difference between the results of the analytical model and high‐fidelity model is compared. This difference is relatively small and can be easily eliminated by a simple differential correction procedure. The launch window duration...
