Over decades of space exploration, thousands of rockets have launched, resulting in a sea of debris circling the Earth. It's estimated that there are 30,000 objects over 10 cm, 500,000 marble-sized debris, and 100 million smaller than that.

Episode host Anna Ploszajski bravely goes into the unknown, in conversation with:

Mike Lindsay, Chief Technology Operator at Astroscale, a start-up seeking to make space more sustainable by pioneering clean-up tech.

Hugh Lewis, Professor of Astronautics at the University of Southampton.

New episodes - conversations about how to rebuild the world better - every other Friday.
