Europe awaits confirmation of Mars landing

AFP  |  Darmstadt (Germany) 

Mission controllers were anxiously awaiting confirmation today that a tiny European craft had landed on Mars as part of an ambitious quest with to find evidence of life on the Red Planet.

The paddling pool-sized "Schiaparelli" lander was due to end its seven-month, 496-million-kilometre trek from Earth with a dangerous dash for the surface through the Martian atmosphere.

A direct signal from Schiaparelli to a radio telescope based in was lost, but ground controllers in Darmstadt, Germany, stressed this was no indication of trouble.

Its Trace Gas Orbiter (TGO) mothership, meanwhile, was on its own hairy mission to enter the Red Planet's orbit, at a distance of some 175 million kilometres from Earth.

Confirmation that both manoeuvres were correctly executed is not yet in.

"So far everything is going well," flight director Michel Denis said at the European Space Agency (ESA) mission control centre in Darmstadt today afternoon.

The signal was always very faint, contained no information about the lander's health or progress but was "nice to have", said ESA spacecraft operations manager Andrea Accomazzo.

"Currently we are not receiving any single radio signal from Mars," he said after the scheduled landing time. "But this is absolutely nominal."

Controllers will only know what is really going on once signals from the craft are received via ESA and NASA satellites in Mars' orbit, some time after 1630 GMT.

Schiaparelli is a trial run of atmosphere entry and landing technology for a larger and more expensive rover that will follow it to the Martian surface in a few years.

It had been free-falling to the surface since Sunday, when it separated from the TGO.

The test lander woke up, as scheduled, minutes before it was due to arrive at Mars' atmosphere at 1442 GMT, the ESA said.

Schiaparelli's main job is to test entry and landing technology for the planned rover -- the second phase and high point of ExoMars.

The TGO, in turn, is charged with sniffing atmospheric gases potentially excreted by living organisms -- however small or primitive.

While life is unlikely to exist on the barren, radiation-blasted surface, scientists say traces of methane in Mars' atmosphere may indicate something is stirring under the surface -- possibly single-celled microbes.

The TGO orbiter started a 139-minute engine burn as scheduled today to slow it down enough to be captured by Mars' gravity, the ESA said.
