Juice mission

  • Recently, the European Space Agency is set to launch the Jupiter Icy Moons Explorer (Juice) mission to explore Jupiter and its icy moons, namely Ganymede, Callisto, and Europa.
  • To be launched from French Guiana on an Ariane 5 launcher.
  • The mission is set to reach Jupiter in 2031.


  • To create detailed maps of the moons’ surfaces and look beneath them to probe the potential habitable environments by analyzing the water bodies underneath.
  • To create a comprehensive picture of Jupiter by trying to understand its origin, history, and evolution.
  • The focus will be on Ganymede (the largest moon in the Solar System, which generates its magnetic field).
  • The three moons, Ganymede, Callisto, and Europa, are believed to hold immense amounts of water, potentially making them habitable.
