Sounding the alarm: ESA introduces space environment ‘health index’
The congestion and pollution of Earth orbit is quickly getting worse. We need to be able to quantify how our behaviour impacts the orbital environment in the future. To this end, the European Space Agency (ESA) is adding a new health index to its yearly Space Environment Report that summarises in one number the status of our space environment over time.
