Abstract: An apparatus and system for lunar landing are disclosed that use an image-based analysis to enhance descent control and surface proximity estimation. Cameras oriented toward the lunar surface capture sequential images during terminal descent. By analyzing the rate of change in brightness histograms derived from the images, dust-induced obscuration of the surface is detected and contrast loss in surface features quantified. The histogram-based approach enables real-time determination of the altitude and attitude of the lander, even when radar or other sensor techniques become unreliable due to dust. Pre-calibrated models or lookup tables are used to correlate histogram changes with altitude, generating control signals to adjust descent rate and attitude for the landing. The system operates as a primary or redundant proximity sensor.
