Summary

Much of our daily lives is made possible by the placement of objects orbiting our planet. From GPS, to weather forecasts, even your bank's ATM wouldn't be able to function without a timecode from space confirming when your transaction took place. So we're going to explore whether the increasing numbers of satellites up there is a problem, how we can use them to spot potential disease outbreaks before they even happen; why space weather is a threat, and even how one company are planning to forge metals aboard satellites and make things in microgravity for use back here on Earth!
