Pluto, Is That You?

Yesterday I took an online quiz to test my knowledge of the planet Pluto, and to my surprise I got all the questions right. I didn't know I knew that much about it, but I have seen a couple of news articles about the New Horizons space probe and recently read the story of how Pluto was discovered in 1930. I understand that the photographs received by NASA have revealed the planet to be a bit bigger than scientists thought it was, and I'd like to congratulate Pluto in this regard. It must be hard enough hanging out there in the Kuiper Belt without being demoted; maybe being bigger will give Pluto back its bona fides.

When I was growing up, I thought of Pluto as almost the mascot of the solar system, probably because it shared its name with that friendly but goofy Disney dog. At the same time, its remoteness gave it a mystique no other planet had. Now all these years later, images of its surface are raining down on us from the space probe, and we're getting acquainted with its actual features. Imagine an object the size of a piano traveling safely for nine years across the vastness of space, arriving in the vicinity of distant Pluto in good enough condition to send back crisp images. What a miracle.

I read today that scientists are excited about the size of the mountains on Pluto and the likelihood that the planet has water. Pluto seems to be defying expectations in lots of ways, but surprisingly, the images I've seen don't stray all that far from what I might have imagined if you'd asked me to draw it when I was growing up. I think I imagined it as a very cold, silent, dim place, a place it would be hard to get to know.

As everyone knows from mythology, Pluto was also called Hades and was the god of the underworld--conceived as being below the ground, not out in space. Pluto was in some way connected with wealth, which may have come from the fact that he ruled his own vast kingdom, quite distinct from that of the upper regions. Despite the riches below the earth, his realm was a dim, inaccessible place for the living, not a place to go willingly even if you could get there, in contrast to all the effort it's taken to get to his planetary namesake.

We've sent a spacecraft as our emissary to the planet Pluto, a destination that will, in its own way, have a wealth of features to discover. I sometimes have mixed feelings when I read about explorations of other worlds and plans to possibly exploit them for our gain (though I realize anything like that is probably far in the future for distant Pluto). If only we could get our own house in order on Earth I might feel better about the possibility of colonizing other worlds, but I guess if we waited until we were perfectly wise we might never get anywhere.

I hope the images we're receiving will make all the work that went into the New Horizons project pay off, and I'm glad the ashes of Pluto's discoverer, Clyde Tombaugh, went along for the ride. That was a lovely gesture that puts a human face on the whole enterprise and makes a nine-year voyage seem perhaps a bit less of a lonely ride. It also makes Pluto seem not quite as remote as it once was--though regardless of the distance, Pluto will always be a part of my solar system.
