Key Points:
- The European Space Agency (ESA) has produced the most detailed and color-accurate true-color mosaic of Mars using data from the High Resolution Stereo Camera (HRSC) aboard the Mars Express mission, covering the entire planet at about 2 km per pixel resolution.
- Unlike previous exaggerated red and brown images, this mosaic reveals Mars in muted grays, yellows, oranges, and pale blues, highlighting mineral diversity and geological features such as volcanic activity and hydrated minerals.
- The HRSC camera's multispectral, stereo, and high-resolution imaging capabilities, combined with over 20 years of data and complex radiometric and geometric corrections, enabled the creation of a seamless and scientifically valuable global map.
- The true-color mosaic helps researchers
