Astro Pi

Aboard the International Space Station are two specially equipped Raspberry Pi computers, called Astro Pis. They are there to run code written by children and teenagers.

Each Astro Pi has a camera, an LED display, buttons, and a joystick. They also have a range of environmental sensors: a gyroscope, a magnetometer, an accelerometer, and sensors measuring humidity, pressure, and temperature.

Your code onboard the International Space Station with the Astro Pi Challenge

Announcing the 2018-19 European Astro Pi Challenge in partnership with the European Space Agency (ESA). It’s open to students from all 22 ESA member countries, including associate members Canada and Slovenia. In Mission Zero, students aged up to 14 write a simple Python program that will display a message on the International Space Station for 30 seconds.

Each year, we challenge students aged up to 19, and from across Europe and beyond, to write code for astronauts to run on the Astro Pis. Our Astro Pi programme aims to inspire young people to form an enduring interest in coding, space science, and STEM subjects and careers.
