The latest Mars image mosaic as seen through the lens of the High Resolution Stereo Camera on ESA’s Mars Express.
The mosaic comprises 2702 individual swaths of the martian surface, up to and including the spacecraft’s 10 821st orbit of the planet, which it completed on 30 June 2012.
At this time, 87.8% of the surface had been mapped at any resolution, with 61.5% mapped at a resolution of 20 m per pixel or better.
Each white marker around the border of the image represents 10º of latitude or longitude.
This image was released as a Space Science Image of the Week feature on 4 February 2013.
