The International Space Station (ISS) is under constant threat from objects moving at speeds not often seen here on Earth. Space junk and micrometeoroids travel many kilometers each second, testing the impact shielding that protects the astronaut inhabitants. This Astro-Pi resource for secondary schools touches on equations and graphs of motion, and looks at how forces can lead to changes in the shape and motion of objects. As well as being appropriate for enhancing teaching in science it sufficiently prepares teams of students for entry into the Astro-Pi Raspberry Pi competition. With the Astro-Pi add-on board they can use the accelerometer, gyroscope and magnetic field sensors to provide information about the motion of objects - including the ISS.
