A hybrid guidance framework was presented that may be an excellent option to satisfy both of these requirements. A combination of a local and global controller are used in concert to guide the vehicle from the initial state to the desired target on the lunar surface. Using the hybrid theoretical framework, we have formally shown that the combination of the two guidance algorithms is globally asymptotically stable. A particular set of algorithms are chosen for demonstration, and a set of Monte Carlo simulations show that the algorithm is very capable of successfully retargeting to a new landing site if the original location is deemed unacceptable for landing. The presented hybrid framework provides a large amount of flexibility, and as such, there is still quite a large amount of research and exploration that can be done into the true potential of using such a framework for spacecraft landing guidance.
