摘要
[編輯]描述A Patch of Black On Mercury.jpg |
English: The crater in the lower right-hand corner of this image has a patch of very dark material located near its centre. The region of this image has been seen only with the Sun high overhead in the sky. Such lighting conditions are good for recognizing colour differences of rocks but not well suited for ascertaining the topography of surface features from shadows. The shape of the surface in this area is difficult to resolve given the lighting angle, but the dark patch is not in shadow. The dark colour is likely due to rocks that have a different mineralogical composition from that of the surrounding surface.
Image Mission Elapsed Time (MET): 131771988 Instrument: Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) Resolution: 260 meters/pixel Scale: This image is about 270 kilometres across Spacecraft Altitude: 10,100 kilometres |
