ESA & CLS: Using Space to Address Ocean Marine Litter 

Around 250kg of plastic leak into the ocean each second.

Monitoring marine plastic from the Earth’s surface is not easy because it’s not possible to see large amounts of the ocean at one time, however, Space provides much-needed help.

In 2019, the European Space Agency (ESA), launched a call for ideas – the first of its kind – for monitoring marine litter from Space.

With more than 30 years of experience developing innovative space-based solutions to help protect the planet and sustainably manage its resources, CLS answered this call and the MARLISAT project was submitted, and accepted, through ESA’s Open Space Innovation Platform.
