Mission Zero

Mission Zero

Mission Zero offers students and young people the chance to have their computer programs run in space on the ISS! Teams write a simple program to display a message to the astronauts onboard. You don’t need special equipment or coding skills, and all participants that follow the rules are guaranteed to have their programs run in space. You will also receive a special certificate showing where exactly the ISS was when your program ran!
