Abstract

Martian Moons eXplorer (MMX) is a sample-return mission of Phobos, the larger moon of Mars. To achieve the mission, a high-resolution 3D model of Phobos is essential, which requires a large number of high-resolution images to be sent back to Earth with enough quality before carrying out the landing activity. To realize this, the data transfer bandwidth is the bottleneck, and we adopt CCSDS 122.0-B-1 image compression, a variation of data compression based on the DWT method. This method allows us to select only one output quality for one image compression. On the other hand, the data transfer strategy shall be to transfer minimum-quality images first for quick looks and full-quality ones later. To realize this with the least computing power, we modified the method to output a low-quality full image and two supplemental data sets to better quality. This work is based on the CCSDS 122.0-B-1 implementation by a group of the University of Nebraska Lincoln.
