Straight to the point
This stunning High-Resolution Stereo Camera (HRSC) image was captured during Mars Express' 14,125th orbit of the red planet.
It showcases the Martian north polar region, revealing the imposing north polar cap, a striking bank of stratocumulus clouds over Borealis Planitia, and the rugged highlands of Tempe Terra to the left.
Key Space Science
The image shows the Martian north polar cap, primarily water ice with a seasonal carbon dioxide covering (dry ice). Studying its composition and changes helps us understand the Martian water cycle and climate.
The stratocumulus clouds indicate atmospheric circulation and condensation processes in the Martian atmosphere.
Understanding the Martian water cycle and the potential for past or present habitability is crucial for astrobiological studies and the search for life beyond Earth.
