As an expert in astrodynamics and space mission design, Ciara Mcgrath has the exciting job of making sure spacecraft are sent into orbit in the most efficient and sustainable way. In this episode she tells us about the importance of satellites, from the work they do monitoring the global climate, to the impact they have on our daily lives - like how they make it easier to buy your groceries.

Sairah’s biogas unit is our prototype spotlight this week. It’s a piece of kit that turns waste food and organic materials into useful gas. We hear from the team at Glasgow Caledonian University, who are bringing the design to life.

Thanks to the children from Lisnasharragh primary school in Northern Ireland who shared their engineering ideas with us at the start of the show.
