what our trip to pluto can teach us about ourselves
New Horizons’ flyby of Pluto let us see a brand new world that doesn’t fit in our conventional categories, and reminded us that at our heart, we’re explorers, not drones.
After finally getting a close look at Pluto and putting many decades of speculation to rest, there are three important things to keep in mind. First is that humans have now seen every world we once considered a planet in our solar system and have taken pictures and measurements that will give us decades of research to help us figure out where we came from and provide a basic foundation for figuring out if we are really alone in our tiny little corner of the cosmos. Second is that we need to keep thinking about how to properly define what a planet is, since Pluto shows pretty much all the signs of geologic activity we expected to find, and isn’t merely a rock which simply hangs around in space, absorbing the solar wind and asteroid impacts. And third, and in many ways very exemplary of how science can drive us to do odd but beautiful things, is that a container on New Horizons was carrying the ashes of the scientist who discovered Pluto, and in a way, the man who set the chain of events ending with this mission in motion, was there when the small world he spotted so many decades ago, was finally visited for the very first time.
People tend to lament spending money on basic science, curiosity-driven research which is not going to be obviously responsible for creating new jobs or founding new companies, but simply asks what is and why it works that way. But notice how many people were fascinated to see an icy, remote world, and how impressed they were that a 3 billion mile flight was planned to within several thousand miles between spinning alien objects we couldn’t see as anything more than a few faint pixels with out most powerful telescopes. We may have chained ourselves to desks in gray offices, toiling away on reports no one wants to read under the buzz of florescent lights as we watch the clock for quitting time, but deep inside we’re still explorers and wanderers. That’s why no matter how dullards and politicians who pander to them try to bankrupt space travel and exploration, we’ll always find a way to go. The urge is always there. The challenge attracts way too many curious minds. Clyde Tombaugh found a way to visit the outer solar system. He may have not been alive for it, but still, where there was a will to explore, we found a way…
