  1. Europa Jupiter and thisGalileanmoons : Callisto, Europa, Io,Ganymede The smallest of four Galilean moon of Jupiter Discovered in 1610 by Galileo Galilei Study between 1995 and 2003 with the spacecraft Galileo.

  2. Life … in Europa ? • Surface is composed of water ice • Possibility of water beneath the frozen ice crust. • Possibility of oxygen • A prominent double-ridge feature on Europa, most likely a crack in the icy shell • Hypothesis : warm ice rising up through the colder ice of the outer crust • Life in the Crack ?

  3. Future missions • For know if live exist , one solution : go to explore Europa • The next project : Launch a rover. Objective : • - Travel the Ice Water • - Then explored the ocean • A robot like DepthXRobot for Mission to Europa. • DepthX : autonomousunderwatervehicle • The date of launch is unknown at this time, around 2026.

  4. Life on Mars ? • Explore since a long time : • Spacecraft, satellite. • On the off chance to find life. • Some theories : • Life had existed before life on Earth • Life had never existed on Mars • ??? For observing mars : robot has been launched : Curiosity

  5. Curiosity rover Launch Date : 26 November 2011 Mars landing : 5 August 2012 • Mission : Biological, Geological andgeochemical Planetary process and Surface radiation

  6. Recently Descoveries • Martian Rock with strange properties.

  7. Environmental • Water • Distance of a star : • Temperature : which determine the presence of liquid water • Light : for vegetable • The quantity of toxic radiation (ex : UV)

  8. Environmental • The nature of Sky (Oxyhen, methane co2 ?) • Chemical nature of the oceans • Electrical discharge (lightning) • The mass of the planet and of the star

  9. Silicon • life on Earth is built upon carbon • Another element build life ? Possibility of life build upon Silicon • But questioned : Carbon is usely than Silicon, and different inertia.

  10. OtherChemicalelement • Oxygen • Nitrate • Fer
