A Mars lander is due to leave its mothership and head toward the red planet’s surface.

After a seven-month journey from Earth as part of the European-Russian ExoMars program, the Schiaparelli lander is expected to separate from spacecraft Trace Gas Orbiter on Sunday and start a three-day descent to the surface.

It will test technologies for Europe’s planned first Mars rover, which will search for signs of past and present life.

Schiaparelli represents only the second European attempt to land a craft on Mars.

It follows a failed mission by the British landing craft Beagle 2 in 2003.

Landing on Mars, Earth’s neighbour some 56 million kilometres away, is a notoriously difficult task.

It’s a mission that has bedevilled most Russian efforts and given NASA trouble as well.

The United States currently has two operational rovers on Mars, Curiosity and Opportunity.

But a seemingly hostile environment has not detracted from the allure of Mars, with US President Barack Obama recently highlighting his pledge to send people to the planet by the 2030s.

Elon Musk’s SpaceX is developing a massive rocket and capsule to transport large numbers of people and cargo to Mars with the ultimate goal of colonising the planet.

Musk says he would like to launch the first crew as early as 2024.

The primary goal of ExoMars is to find out whether life has ever existed on Mars.

The current spacecraft carries an atmospheric probe to study trace gases such as methane, around the planet.

Scientists believe that methane, a chemical that on Earth is strongly tied to life, could stem from micro-organisms that either became extinct millions of years ago and left gas frozen below the planet’s surface, or that some methane-producing organisms still survive.
