Astronauts must have many skills, in-depth knowledge, and be in top physical condition. And while it takes years of training to prepare for spaceflight, the first steps to building those key skills begin here on Earth, from a young age.

In Missioon X: treeni nagu astronaut, students will learn the key elements to keeping fit and staying healthy in space and on Earth. Developed by space scientists and fitness professionals working with astronauts and space agencies across the world, Mission X uses the excitement of space exploration to inspire children to learn about science, nutrition, exercise ja space. The project can be delivered either through the curriculum, through collapsed timetable days, through homework challenges or clubs … or a mixture!

Project objectives

Mission X aims to promote the teaching and learning of STEM competences and physical skills through two sets of activities:


  • Physical activities are hands-on training missions targeting strength, endurance, coordination, balance, spatial awareness, and more.
  • Scientific activities are classroom investigations which focus on STEM subjects and allow students to practice scientific reasoning, critical thinking, teamwork skills, and more.
