Self-Conscious

Cassini is no more. The Saturn-bound satellite was launched in 1997 when the earth was a very different place. As it’s four-year sell-by date passed, the little robot who could kept on snapping photos around the ringed giant and its moons. Remote controlled from three planets and an asteroid belt away, it was decided that the explorer had to be destroyed in Saturn’s thick atmosphere rather than contaminate one of the moons where life might someday be found. Yesterday the probe burned up on its way through Saturn’s perpetual cloud bank. This has led to many emotional tributes, even among scientists who believe Cassini was just a machine. It also shows us how little we really know about consciousness.

During the two decades that Cassini was in space, we’ve learned quite a bit about animal consciousness here on our own planet. Many are now finally becoming convinced that we share this strange quality we can’t even define with other biological entities. Well, at least the “higher” kind. And we can’t help but think that maybe our more intelligent machines possess it too. We treat them as if they’re alive and willful. That could be a case of our own consciousness projecting itself onto inanimate matter—that’s something consciousness is pretty good at too—but since we lack the ability to measure consciousness, we can’t know if it’s there or not. To hear the astronomers talk, we’re going to miss Cassini, a machine that outperformed expectations. Ironically, once we get machines off the earth they tend to do that, even without oil changes every 5000 miles.

Down here on earth we complicate consciousness with cash. Devising an elaborate economic system to demonstrate who can buy power in the White House and who can’t, we want to know who is more important than whom. It’s a simple metric. Bank accounts tell the truth, no matter what the level of consciousness—or even of sentience—that the account holder may have. And then we wonder why a nation that can send a satellite three planets away can’t even figure out that all races should be treated equally and fairly. Cassini was a collaborative effort. Different races, genders, and economic classes contributed to its remarkable voyage. Eyes around the country were moistened when its last image was projected to earth. We wisely decided to immolate our satellite before we could contaminate another world. Meanwhile on our own planet we’re barely conscious of what we continue to do.
