Anaglyph of Volcanic Vent Near Discovery Rupes


Like yesterday's image, and the one from last week, today's image features the same potential volcanic vent. However, today's image is actually a combination of two additional images that were taken by the spacecraft 255 seconds apart. During that time of just over 4 minutes, the spacecraft had moved enough to provide slightly different viewing angles of the same surface, enabling this 3D representation to be made. Find a pair of red-cyan glasses to view the 3D image, and the image has been rotated such that north is to the left to enhance the 3D effect.

This image was acquired as a targeted set of stereo images. Targeted stereo observations are acquired at resolutions much higher than that of the 200-meter/pixel stereo base map. These targets acquired with the NAC enable the detailed topography of Mercury's surface to be determined for a local area of interest.
