PARIS: A European lander is to separate from its mothership today for a million-kilometre descent to Mars, testing vital technology ahead of a mission to explore the Red Planet for signs of life.
The high-stakes operation comes nearly 13 years after European ambitions were dealt a blow when its first scout to Mars disappeared on landing.
A 600-kilogramme, paddling pool-sized lander called Schiaparelli is to separate from an unmanned craft called the Trace Gas Orbiter (TGO) after a seven-month, 496-million- kilometre trek from Earth.
Separation is scheduled for 1442 GMT (2012 IST), with the landing due to take place on Wednesday, according to the ESA website.
The operation is a testbed for the second chapter of the so-called ExoMars mission, a joint exploration with Russia.
The second part will begin in 2020 with the launch of a rover designed to move around and drill into Mars in search of extra-terrestrial life — past or present.
Today’s separation manoeuvres will be followed closely by mission controllers in Darmstadt, Germany, 175 million kilometres away.
Mars has been a graveyard of space dreams.
Sending an unmanned mobile explorer is especially tricky.
Rovers have to arrive intact after a long trip across space, followed by a descent through Mars’ thin, carbon dioxide atmosphere.
The descent itself is an acrobatic feat, requiring protection from atmospheric friction, extreme braking just above the surface and then a soft touchdown in terrain where any jagged rocks and craters could spell doom.
So far, only the United States has successfully operated rovers on the planet. (AGENCIES)
