Elon Musk’s SpaceX will launch a satellite on November 10 that can measure rising sea levels from orbit.

The Sentinel-6 Michael Freilich satellite will update maps of the oceans every 10 days, showing scientists how much rising sea levels are eroding coastlines. 

On-board digital altimeters can measure millimeter-scale changes in elevation from the satellite, which will orbit 830 miles above Earth.

The aim of the data is to help decision-makers and government better protect coasts and prepare for floods.
