Next year, NASA and the European Space Agency's drilling rovers are to leave for the red planet to seek traces of life deep under the Martian surface. According to Dr Jim Green, who is involved with both missions, it is possible that at least one of them will discover the long-anticipated evidence. The National Aeronautics and Space Administration's (NASA) Chief Scientist Jim Green has warned in an interview with The Sunday Telegraph that Earth is not prepared to find life on another planet, something which could possibly happen within a couple of years. According to the researcher, Europe's ExoMars Rover, named after chemist Rosalind Franklin, and NASA's Mars 2020, which will be launched next March and arrive on Mars in 2021 to drill and look for signs of extra-terrestrial life, have chances of finding it. Core samples that the ESA's ExoMars will extract will then be studied for organic matter, while samples taken by NASA's rover from Martian subsurface rock formations will be sent
