  • THE MISSION:
    Mars Express, so called because of the rapid and streamlined development time, represents ESA's first visit to another planet in the Solar System. The spacecraft borrows technology from the failed Mars 96 mission and from ESA's Rosetta mission that is currently en route to comet 67P/Churyumov-Gerasimenko. The mission helps to answer fundamental questions about the geology, atmosphere, surface environment, history of water and potential for life on Mars.
