The mission

Since beginning science operations in 2004, Mars Express has provided breathtaking views of Mars in three dimensions. It has provided the most complete map of the chemical composition of the atmosphere, studied Mars’s innermost moon Phobos in unprecedented detail, and traced the history of water across the globe, demonstrating that Mars once harboured environmental conditions that may have been suitable for life.

Launch date: 2 June 2003
Arrival at Mars: December 2003
Status: In operation
Targets: Mars's atmosphere, surface and subsurface; Mars's moons Phobos and Deimos

10 m imaging resolution
8 instruments
1120 kg launch mass
2 decades of operation
