Coverage maps of the Mini-SAR experiment aboard India’s Chandrayaan-1 lunar orbiter as of mid-March 2009. Mini-SAR has mapped about 80% of both of the moon’s poles. The polar excluded zone is a consequence of the side-looking nature of the instrument; these zones will be filled by both scatterometry (in which the instrument views the moon straight downward at low resolution) and high-angle SAR, in which operators roll the spacecraft 9 to 12 degrees to look at areas closer to the ground track.
