Space science is one of HM Government's 'eight great technologies'. In this lecture I will explain the mathematics behind satellites, showing how they are controlled, how they are sent to distant planets and how they transmit and receive data over vast distances. I will also explain how GPS systems work and show how General Relativity plays a vital role in making GPS systems so accurate. I will finish by showing a link between space science and Origami.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/lectures-and-events/maths-goes-into-spaceGresham College has been giving free public lectures since 1597.
