Music. Jim Garvin: Everything we've ever put into space, into orbit, every image of the Earth, every echo of the universe, it all started with an idea. An idea of how to explore. Some of the greatest minds in the country here at Goddard Space Flight Center have been working to take the ideas and map them into the methods of exploring. The way we do that is by building satellites. And right here at Goddard Space Flight Center we put together the ideas with the How, the building of the satellite. Now what are the questions we need to ask? How do the oceans work? What is happening to the Earth's climate? How is the Sun changing? How can we predict space weather? These are the foundational ideas that drive the questions that lead to the spacecraft. The Idea phase is all about the Why. The Design phase and the following phases are all about the How.
