"20 Years of Mars Data Captured in One Stunning Mosaic Image"

The European Space Agency's Mars Express orbiter has mapped the Martian surface using its High-Resolution Stereo Camera (HRSC) for almost 20 years. To celebrate the mission's 20th anniversary, a series of global color mosaic images were live-streamed from the Mars Express orbiter to Earth. The mosaic is the result of a high-altitude campaign conducted by the HRSC science team and state-of-the-art image processing, providing valuable insight into the Martian environment, including revealing the surface composition, demonstrating how water once flowed there in the past, and modern meteorological phenomena.
