The 2023 Walk to the Moon Challenge runs from 16 January to 31 May 2023, where teams of students and families complete physical and scientific activities to earn steps for their country.  Earned steps help the Mission X mascots walk 384 400 km from Earth to the Moon!

Mission X is designed for students age 8-12, but open to all ages. The challenge is open worldwide for school teams and families (teams must be led by a teacher, mentor, educator, or parent). Registration remains open throughout the challenge. 

Test your skills and train like an astronaut with activities like Yoga in Space with Samantha Cristoforetti, developed by space scientists and fitness professionals working with astronauts and space agencies across the world.

Mission X is a collaboration between ESA and the UK Space Agency, facilitated by the ESERO network and National Organisers.
