Mercury mosaic released by USGS Flagstaff team
The USGS Astrogeology team in Flagstaff released a new mosaic of the planet Mercury at last week's AGU meeting, showing the 55% of the planet never seen by humans before.
The imagery came from the MESSENGER spacecraft that completed its third and final fly-by of Mercury in September.
