One of the things I hope comes out of focusing attention on the Cassini-Huygens mission to Saturn with “Outside In” is that exploration is more than just “wham, bam, thank you ma’am.” This recent story on discovery of methane on Mars points to how much can still be learned about a world even after decades of exploration, dozens of spacecraft from several nations and centuries of earthbound telescope exploration.
In fact, think how many fundamental questions about Earth are still up for grabs and we’re obviously right here by the billions. But we are lacking one huge piece of data to help us understand Earth. That piece of data is at least one other planet that supports life (or discovering other planets just like our except they have no life).
If we are really serious about understanding our planet, solving our problems and securing our future, this is mission one – Understanding Earth. The only way to do that is to find more planets like ours. In essence, this is core of what “Outside In” is all about.
