Mars Express has been orbiting Mars since Christmas Day 2003, making it ESA's oldest operating interplanetary mission. Its MARSIS radar has detected subsurface water ice deposits and its HRSC camera has mapped the planet in stunning detail.
After more than two decades, the spacecraft continues to return valuable data on Mars' atmosphere, surface, and subsurface.
