Have you ever looked up at the sky and wondered at the vastness of space? If so, you are not alone. Space exploration has long been a fascinating and myste- rious subject, and it continues to captivate the imaginations of people all around the world to this day. Traditionally, telescopes have been the primary tool for ex- ploring the objects closest to humans in the cosmos. However, due to their short working distance, they can only provide a limited amount of information [1]. To gain a deeper understanding of celestial bodies and their environments, planetary exploration missions have become an essential component of space exploration. By deploying spacecraft to conduct close-up observations and measurements, scientists can gather more detailed and precise data that cannot be obtained from telescopes alone. Navigating and choosing a safe landing spot during a planetary landing mission can be one of the most challenging tasks. Many recent planetary missions have relied on either operator control or predefined maps to accomplish this. For instance, the Japanese Hayabusa2 sample return mission’s initial landing stage was manually controlled by an operator [2], while the Mars rover Perseverance, launched in July 2020,relied on satellite images to identify a safe landing spot on the Martian surface [3]. Despite the success of both missions, these methods may not be suitable for future missions to distant space objects. Therefore, the implementation of an autonomous system for navigation and hazard avoidance is essential ​
