Mars Express in orbit around Mars

Mars Express will left Earth for Mars in June 2003 when the
positions of the two planets made for the shortest possible route, a condition that occurs once every twenty-six months. The intrepid spacecraft started its six-month journey from the
Baikonur launch pad in Kazakhstan onboard a Russian Soyuz/Fregat launcher.

Mars Express began the six-month interplanetary
cruise at a velocity of 10 800 km/h relative to Earth. Five
days before arrival in December 2003, Mars Express will
eject the Beagle 2 lander, which will make its own way to
the correct landing site on the surface. The orbiter will then
manoeuvre into a highly elliptical capture orbit, from which
it can move into its operational near-polar orbit.
