ExoMars probe set to sniff out signs of life on the Red Planet

It has taken a while, but next week Europe and Russia are going back to Mars.
 On 14 March the ExoMars Trace Gas Orbiter (TGO) will blast off from the Baikonur Cosmodrome in Kazakhstan aboard a Proton rocket.
 Its mission: to understand the planet’s atmosphere and search for signs of biological and geological activity.
