What is special about the color image of Mars shown here is that it pictures the upper as well as the lower horizon in a global view. This image is one out of more than 1000 HRSC views and movies that have been released by ESA, DLR and FU Berlin since the start of the Mars Express mission on 2^nd June 2003. During the last 15 years the HRSC instrument has done an incredible good job in obtaining images of our neighbor planet Mars in all its facets. Even now, after more than 18,000 orbits around Mars, HRSC is still reliably transmitting data to Earth that extends our knowledge of the Red Planet.
