What is the European Astro Pi challenge?
Primary & Post Primary Level


The European Space Agency and the Raspberry Pi Foundation invite young people to join the brand-new European Astro Pi Challenge 2023-2024. Get involved in the amazing opportunity to send your computer program to space!

Run your code in space!

This summer we saw ESA Astronaut Andreas Mogensen launched to the International Space Station. Get ready: this school year it will be Andreas overseeing your Astro Pi programs running on board the ISS!!

Mission Zero

Here are some examples of images created by last year’s Mission Zero participants. What will you create?

In Astro Pi Mission Zero, the challenge’s simpler category, teams of young people write a simple Python program to take a reading using the colour sensor on one of the ISS Astro Pi computers and display a personalised pixel art image for the astronauts on board the ISS.

This coding activity can be completed in around one hour, for example during a school lesson or coding club session. It can be done in a web browser, on any computer with internet access. No special equipment or coding skills are needed, and all teams that follow the guidelines will have their program run in space.

The theme for the 2023-2024 is ‘fauna and flora’: young people are invited to program inspiring pixel art images or animations of plants and wildlife that will display on the Astro Pis’ LED screen, to remind the astronauts aboard the ISS of Earth’s natural wonders.

All young people that meet the eligibility criteria and follow the official Mission Zero guidelines will have their program run in space for up to 30 seconds. Participants will receive a personalised certificate that will show the exact start and end time of their program’s run, and the position of the ISS while their program ran.

Mission Zero 2023/24 opens today, Monday 18 September, and is open for submissions until Monday 25 March 2024.

A renewed Mission Space Lab

In this year’s Mission Space Lab – the challenge’s more advanced category – ESA astronauts are inviting teams of young people to write computer programs to solve a specific scientific challenge: to measure as accurately as possible the speed that the International Space Station (ISS) is travelling. To achieve this, teams can use the Astro Pi computers’ sensors (sense HAT) and camera to gather data about the orientation and motion of the ISS as it orbits the Earth

Thanks to this new format, ESA and the Raspberry Pi Foundation made it possible for many more teams to run their programs in space and get a taste of space science.

Registration and submissions for Mission Space Lab will open on 6 November. More information is coming soon!
