The European Space Agency is looking to send a mission to Jupiter and its moon Europa in 2018.
Currently the mission is called (deep breath) 'The Jovian Minisat Explorer Technology Reference Study'. So... it needs a proper name to take it to the next stage of development.
We asked you if you could think of a good name for the mission.
The competition has now closed. We'll update this page with more news about the mission as time goes on.
Further information can be found at Jovian Minisat Explorer study page.
