Space is polluted: 1M junk objects orbiting Earth are deadly as bullets when colliding at high speed into the satellites we need for communication, weather warnings, banking, & more. With space tourism a reality, they risk human lives too. Space environmentalist Moriba Jah invented Wayfinder, which fingerprints these objects, tracks and predicts crashes. It seeks to uncover our biggest space polluters, their behaviors and consequences. He + Neo4j’s Sudhir Hasbe show how Wayfinder works, why it matters, and why we need to embrace stewardship of Near Earth as if our lives depend on it.
