Societies have rules to stop them from descending into chaos - at least that's what Constitutional scholar Cindy Skach used to believe. Her career was spent advising governments and writing constitutions to help fix society in some of the most fractured, war-torn corners of the world. That was until 2009, when she survived a missile attack while in Iraq helping to revise the constitution - an event that changed her thinking on how societies function. In her book How to Be a Citizen, Skach calls to move beyond constitutions, inviting us to see society not as something imposed by law, but rather something we create together.

Renowned space environmentalist and astrodynamicist specialising in space object detection and identification, Dr Moriba Jah believes it's only a matter of time before someone is killed by falling space debris.

And these numbers are only set to grow with 24,000 satellites set to launch in the next 10 years. Dr Jah is also the chief scientist for Privateer, a start-up co-founded by Apple's Steve Wozniak aiming to enable sustainable growth for the space sector.
