Code your way to space! Each year the Zero Robotics competition challenges students to programme and run commands in a virtual world. Choose the right strategy and put in lots of hard work and your tearn might earn a place in the finals held on the International Space Station.

Spheres − short for Synchronised Position Hold, Engage, Reorient, Experimental Satellites -- move around the International Space Station using 12 jets powered by compressed gas.

This year 18 teams from Italy, Germany, France, Spain, Romania, Belgium and the Netherlands representing 140 European students joined the US competitors writing code to redirect an incoming comet while taking space debris and limited laser resources into account.
