"Most of what we send into outer space never comes back," says astrodynamicist and TED Fellow Moriba Jah. In this forward-thinking talk, Jah describes the space highways orbiting earth and how they're mostly populated by space junk. Learn more about his quest to develop and scale the world's first crowdsourced space traffic monitoring system -- and how it could help solve the debris problem in near-earth space.

Moriba Jah: The world's first crowdsourced space traffic monitoring system

The world's first crowdsourced space traffic monitoring system

Space highways are congested with half a million objects from paint specks to school buses in size, posing a colossal risk.

With only 26,000 out of half a million space objects trackable, the vast majority of orbiting debris remains unmonitored.

ASTRIAGraph, a revolutionary crowdsourced space traffic monitoring system, aims to ensure the sustainability of space use.
