One of the great things about NASA is that all the data returned from all of the missions all over the solar system belong to you, the public. A good chunk of what I write about at this blog depends upon NASA's public data archives, the Planetary Data System, or PDS. By sharing all of the data with the world, NASA enables amateurs and professionals alike to make the most of every precious data bit returned from space. It's not just the raw bits that NASA makes available, either.
