For decades, humans have ventured into space, pushing the boundaries of their mental and physical limits to explore the great unknown. But no professional astronaut can leave Earth without extensive training.

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

In Mission X: train like an astronaut, you’ll 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 students to learn about science, nutrition, exercise and 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.

Walk to the Moon Challenge

Each year from January to May, teams of students can participate in the Walk to the Moon Challenge. During the challenge, teams across the world complete Mission X activities and submit them online to earn points. Points are translated into steps which help the Mission X mascots, Luna and Leo, walk 384 400km – the distance from Earth to the Moon.


The challenge takes place annually from the beginning of January to the end of May.

The challenge is designed to be completed in 6 weeks, but can be adapted to suit alternative timelines. There is no minimum or maximum amount of activities that must be completed to participate in the challenge.

Who can participate?

Age Range: The Mission X activities are developed for ages 8-12, but can easily be adapted for other age groups and skill levels.


  • No minimum or maximum number of team members required to participate, but students are encouraged to work with at least 1 other person.
  • Each team must be supported by a Team Leader (teacher, mentor, educator, or parent).
  • Family teams are welcome.

Open worldwide: National Organisers help facilitate the project in each of our participating countries by providing local support.

  • If your country is not listed, you can still take part in the challenge! Your registration will be managed by our UK National Organiser.

How to complete activities and earn points

The Walk to the Moon Challenge points calculator will open for submissions in January.  Once open, your team can begin completing the physical and scientific activities from the Mission X activity catalogue, and upload the activities on your account to earn points.

A new points calculator will be available in January 2022! Please revisit this page again soon for full instructions on how to upload activities and earn points. 

You can track your team’s progress using the checklist below, while team members can track their individual progress using the Mission Journal: Student Logbook.
