Did you know that astronauts on-board the International Space Station travel much faster than any car or airplane that you see on Earth? Maintaining the right speed is essential for the ISS to stay in orbit. In this year's Mission Space Lab Challenge it is up to you to figure out how fast the ISS is moving around our planet by using the sensors and camera of the Astro Pi computers. Registration is open from 6 November 2023 to 19 February 2024. Visit for more information.
