The European Space Agency (ESA) has offered its best guesses for what happened to a probe it sent towards the surface of Mars.

'So what do you think happened?' The question I kept overhearing at ExoMars Jeremy Wilks Euronews science correspondent

Contact was lost during its descent on Wednesday afternoon (CET), before it reached the surface.

Scientists are working to confirm its status via data received from other satellites, amid fears the probe may have crashed or been destroyed.

The descent went as planned until the parachute meant to slow descent opened within the Martian atmosphere.

But its mothership entered into orbit as planned and the overall Mars mission is being declared a success:

“Mars is the closest planet to us, where we find some situations which are maybe very good for life. So there was a better atmosphere than today, different temperatures, better temperatures and also liquid water – so if there is life in our solar system beyond the earth, then Mars is the most interesting planet,” said Jan Woerner, the European Space Agency’s Director-General.

Controllers at ESA’s headquarters at Darmstadt in Germany did have reason to celebrate: the spacecraft on which Schiaparelli travelled to Mars went into orbit around the Red Planet successfully.

The orbiter carries an atmospheric probe to study gases around the planet such as methane – a chemical that on Earth is strongly tied to life.

It’s thought data the orbiter may have received during Schiaparelli’s descent could provide clues as to what has happened to the lander.

The lander is named after Giovanni Schiaparelli, the Italian astronomer who in 1877 began mapping the topography of Mars.

The probe is part of the European-Russian ExoMars programme, which will search for signs of past and present life on the red planet. It represents only the second European attempt to land a craft on Mars. Britain’s Beagle 2 mission ended in failure in 2003.

Euronews correspondent Jeremy Wilks reported from Darmstadt:

“There is a certainly a sense of unfinished business here at ESA operation centre in Germany. We have very good news: the TGO – the Trace Gas Orbiter – has entered into orbit around the red planet, and that’s going to be a very useful spacecraft in terms of science for many years to come.”

The ExoMars 2016 mission is led by the European Space Agency, with Russia’s Roscosmos supplying the launcher and two of the four scientific instruments on the trace gas orbiter.

The joint operation is in preparation for a rover landing on Mars in 2020 – all part of the quest to find signs of life.
