Med zadnjo serijo preletov, ki bo potekala med 16. februarjem in 26. marcem, bo Mars Express 3. marca postavil nov rekord, ko bo preletel le 50 km od njegove povr\u0161ine.

Sledi skoraj kro\u017eni, ekvatorialni poti, pribli\u017eno 6000 km nad povr\u0161ino planeta. Da bi se izognil tr\u010denju z Marsom, mora po svoji orbiti potovati zelo hitro.

Mars Express bi lahko pomagal razvozlati to uganko. Z raziskovanjem na\u010dina, kako gravitacija Fobosa vpliva na vesoljsko plovilo in spreminja njegovo tirnico, bodo znanstveniki izvedeli ve\u010d o notranjosti lune.
