The U.S.A has launched the Mars Orbiter. It brought a high resolution imaging science equipment, and that is the High Resolution Imaging Science Experiment camera(HIRISE). HIRISE is 0.5 m reflecting telescope, which is the highest one ever carried on a deep space mission, and it has a resolution of 1 microradian (μrad), or 0.3 m from an altitude of 300 km. HIRISE can investigate deposits and landforms resulting from geologic and climatic processes and assist in the evaluation of candidate. As a high degree of lightweight ultra-high resolution camera, the design of its FPA is unparalleled .Therefore we should study and learn it carefully. In this article, first of all we discuss and analyze the characters of the HIRISE FPA in terms of the structural layout, material selection, splicing of the CCD, the CCD package, electronics, processing and transmission, and thermal control measures implementation. Next we put forward the design method of highly lightweight space optical remote sensor FPA combined with the characters of the HIRISE FPA, which can provide a reference to the design of the FPA for some space remote sensings.

Abstract. We have developed a method for automatically detecting the sources of ice block falls at the Martian north polar scarps. Multitemporal red-filter High Resolution Imaging Science Experiment (HiRISE) images were processed by using the open source NASA Ames Stereo Pipeline in combination with the USGS Integrated Software for Imagers and Spectrometers to produce 0.25 m resolution images as well as a 1 m resolution DTM. The multi-temporal HiRISE images were firstly ortho-rectified by the DTM, and then co-registered by using the Enhanced Correlation Coefficient Maximization (ECC) algorithm. We applied the change detection method on the well-aligned sub-meter scale HiRISE images, which were taken in Mars Year 29 and Mars Year 30, to investigate mass wasting at the scarp area centred at 85.0°N, 151.5°E. The idea of the change detection method is to identify changing shadow patterns based on the grayscale difference between the images. The final results show that erosion events occurred at the full length of this study’s scarp within one Mars Year. However, only the upper and lower part of the scarp show erosion activity, whereas the intermediate parts seem inactive, and this correlates with the slope.

The atmospheric dust is an important factor in the evolution of the Martian climate and has a major impact on the scientific exploration of the Martian lander or rover and its payload. This paper used remote sensing images to calculate atmospheric optical depth that characterizes the spatial distribution of the atmospheric dust of Mars. The optical depth calculated by the images of the High Resolution Imaging Science Experiment (HiRISE) in the inspection area of the Spirit rover had a similar temporal variation to the optical depth directly measured by the Spirit rover from the sunlight decay. We also used the HiRISE images to acquire the seasonal variation of optical depths in the candidate landing area of China’s Mars Mission (Tianwen-1). The results have shown that the seasonal pattern of the optical depth in the candidate landing area is consistent with the dust storm sequences in this area. After Tianwen-1 enters the orbit around Mars, the images collected by the Moderate Resolution Imaging Camera (MoRIC), and the High Resolution Imaging Camera (HiRIC) can be used to study the atmospheric optical depth in the candidate landing area, providing reference for the safe landing and operation of the lander and rover.
