The [[Science|scientific]] objectives, in order of priority, are:<ref>{{cite web |url=http://www.esa.int/SPECIALS/ExoMars/SEM0VIAMS7F_0.html |title=Scientific objectives – ExoMars |date=1 November 2007 |publisher=European Space Agency (ESA) |access-date=26 July 2009 |archive-url=https://web.archive.org/web/20121019170339/http://www.esa.int/SPECIALS/ExoMars/SEM0VIAMS7F_0.html |archive-date=19 October 2012 |url-status=dead }}</ref>
* to search for possible [[biosignature]]s of past [[Life on Mars (planet)|Martian life]].
* to characterise the [[Water on Mars|water]] and [[geochemical]] distribution as a function of depth in the shallow subsurface.
* to study the surface environment and identify hazards to future [[human mission to Mars|human missions to Mars]].
* to investigate the planet's subsurface and deep interior to better understand the evolution and habitability of Mars.
* achieve incremental steps ultimately culminating in a [[Mars sample-return mission|sample return flight]].

The technological objectives to develop are:
* landing of large [[Payload (air and space craft)|payloads]] on Mars.
* to exploit [[Solar power|solar electric power]] on the surface of Mars.
* to access the subsurface with a drill able to collect samples down to a depth of {{convert|2|m|ft}}
* to develop surface exploration capability using a rover.
