ICER
ICER is a wavelet-based image compression file format used by the NASA Mars Rovers. ICER has both lossy and lossless compression modes.
The Mars Exploration Rovers “Spirit” (MER-A) and “Opportunity” (MER-B) both use ICER. Onboard image compression is used extensively to make best use of the downlink resources. The Mars Science Lab supports the use of ICER for its navigation cameras (but all other cameras use other file formats).
