      For my job I design the satellites which allow us to see changes on Earth, and normally someone else looks at all the images that come back to see what those changes are, so they are two different jobs.
      The kind of satellites I help to build can see how the ground is moving on earth so we can predict which volcanos will erupt next or where a big earthquake might be so it kind of like being able to see the future! The best way satellites help us see the future from space is by looking for patterns, things like more and more of the polar ice caps melting away or rain forests disappearing. By finding the patterns we can predict what will happen next if humans don’t change what we are doing on Earth.
