So your Ascent-Descent Vehicle has engaged Terrain Relative Navigation, it is taking image captures of the rapidly approaching Martian landscape and matching the contours and heights using stereo cameras, LIDAR altimetry and visual odometry alongside other navigation sensor suites such as the Inertial Measurement Unit (accelerometers, gyroscopes, magnetometers) to localise the descending landing module relative to the Digital Elevation Model, possibly using some of the MACHINE LEARNING classifiers the dreaded AI to position the 2d image / 3d depth map stereo-pair in the observed surroundings. This process can be complicated by poor / variable illumination so perhaps the AI ML models could generate synthetic light intensity maps from the radiant surfaces just like in videogames.

Unfortunately, the AI HYPE MERCHANT and AI DOOMBRINGER

are too busy fighting each either and pummelling each other viciously in the hallway outside Mission Control - behind the CLOSED DOORS you hear something about an AI Atlas? which momentarily increases your hopes that this will help with your terrain map spacecraft task... but it is just some dull AI web browser; you hear AI being proposed for agentic payment protocols, so that AI will just automatically spend your money for you, AI social media imaginary friends, AI influencers and AI actors, AI surveillance neck dongles, AI generated virtual holiday photos and videos, AI generated videogames, AI even for erotic SEX COMPANIONS to howls and protestations of outrage from the AI DOOMBRINGER - none of these really contribute to your immediate space mission right now.

So as you transition from the powered descent phase to the final hazard detection and terminal descent phase for a soft touchdown, you are mostly on your own...
