Where does life come from? Are we really just stardust? Is there life beyond Earth?
Exobiology or Astrobiology combine disciplines such as physics, biochemistry, astronomy and geology to investigate the origins and early evolution of life on Earth and the possibility of life on other worlds. Of course none of these researches would be possible without Space missions.
ESA is contributing a lot in our understanding of the origins of life, thanks to several of its missions: Huygens or Mars Express for example for these last years, soon Rosetta, due to land on a comet in 2014 and later with Exomars.
