Synthetic-Aperture Radar (SAR) is becoming more widely available and increasingly part of Earth observation satellites.

Jason-2 Satellite to Help Improve Maps of Sea Floor

Jason-2 will be collecting data about the sea floor every 5 miles, which will be used to create a high-definition estimate of the average surface height of the ocean in various places around the globe.

Creating a Sustainable Space Environment Using Satellite Sails

by Rebecca Maxwell

European Space Agency scientists are pioneering sustainable space technology through satellite innovation.

A constellation of three satellites form the Swarm Earth Explorer mission. Swarm will identify and measure the magnetic signals that stem from Earth’s core, mantle, crust, oceans, ionosphere and magnetosphere – all of which create the magnetic field that protects our planet. This information will provide insight into processes occurring deep inside the planet and yield a better understanding of the near-Earth electromagnetic environment and the impact solar wind has on Earth.
