Radar satellites and the RADARSAT constellation mission
2018-09-17 - When a radar antenna mounted on an Earth-orbiting satellite sends a beam of radio waves toward Earth, the waves pass through its cloud cover and strike its surface. Some of the waves rebound from Earth's surface, while others scatter. The ones that bounce back to the radar carry with them an imprint of the surface. Canada is a world leader in using radar satellites to observe Earth. The Canadian RADARSAT Constellation is composed of three identical radar satellites, and will provide daily revisits of Canada and the Arctic up to four times every day.
As part of their collaboration for the 2018 edition of Science Literacy Week, the Canadian Space Agency (CSA) and the Natural Sciences and Engineering Research Council of Canada (NSERC) joined forces with Microfiches to create a series of five posters about space projects. The texts were written by the Canadian Space Agency and visually interpreted by Canadian artists.
