Satellite Data Analysis By: Monica Maynard 2012 IISME Fellow

What is a satellite? A small object that orbits another, much larger object (ex. The Moon) Man-made devices that retrieve information from and Earth and other planets in order to study them Some man-made satellites take pictures and others gather number data, which can then be interpreted

Why are satellites important? They can return various forms of information (radiation, images, greenhouse gases, etc.) With respect to Earth, they can cover a large area for investigation The have a much clearer view than telescopes on land They have helped increase communication (cell phones, TV’s, Internet)
