Mars TGO probe despatched on methane investigation - BBC News
Launched from Baikonur in Kazakhstan, the ExoMars Trace Gas Orbiter (TGO) will study methane and other rare gases in the Red Planet's atmosphere, and also drop a lander on its surface.
Controllers received a signal from the probe late on Monday, confirming it was in good health.
Analysis of tracking data indicated that the 4.3-tonne orbiter was on a good trajectory as well.
The European Space Agency's Micah Schmidt, speaking from the organisation's operations centre in Darmstadt, Germany, announced the good news: "We have AOS - acquisition of signal; we have a mission. And for the second time, Europe is going to Mars. So, Go, Go Go! ExoMars!"
