Background
Astro Pi is an annual science and coding competition where student-written code is run on the International Space Station to perform scientific experiments. It began as one of the educational projects for British ESA astronaut Tim Peake in 2015, open to the UK only, and was extended to all ESA member states for the flight of French ESA astronaut Thomas Pesquet last year.
This year Paolo Nespoli and Alexander Gerst are the ambassadors and for the first time associate ESA member states can also participate, including Canada and Slovenia
