In about twenty hours, the spacecraft Cassini will plunge into the atmosphere of Saturn and destroy itself, to protect any potential life on Saturn’s moons. Can’t have Earth-life-tainted space junk floating around out there.
Cassini’s mission has been an astonishing success — with an emphasis on astonishing. It found things that turned some of our notions on their heads, and revealed a small moon with a liquid water geyser(!). It’s going to take a while to figure that one out.
The scientific instrument I most appreciate is the plain ol’ camera – Cassini sent home some beautiful images. Here’s a low-res markup of one of my favorites: A shot of Earth taken through the rings of Saturn.
The universe is still filled with mystery; we’re barely out of our own back yard and everywhere we turn we find things that astonish us. As we struggle with the trials of having a lot of sentient creatures packed onto the rocky parts of the surface of one small planet, we would do well to take a breath and look up, and be awestricken by what we see.
