and the scientists, Brad Smith and Ed Stone and Carl Sagan, came up to tell what they thought they were learning. Roger listened, and tried to think of an interesting question. In a situation like this, the important thing was get yourself noticed, for future reference, then try for an exclusive. He jotted useful phrases:
    “New moons are going to get dull pretty soon.”
    “Not dozens of rings. Hundreds. We’re still counting.” Long pause. “Some of them are eccentric.”
    “What does that mean?” someone whispered.
    The sci-fi man in the khaki bush jacket answered in what he probably thought was a whisper. “The rings are supposed to be perfect circles with Saturn at the center. All the theory says they have to be. Now they’ve found some that aren’t circles, they’re ellipses.”
    Other scientists spoke:
    “May be the largest crater in the solar system in relation to the body it’s on …”
    “There isn’t any Janus. There are two moons where we thought Janus was. They share the same orbit, and they change places every time they pass. Oh, yes, we’ve known for some time those orbits were possible. It’s a textbook exam question in celestial mechanics. It’s just that we never found anything like it in the real universe.”
    Brooks jotted down details on that one; it was definitely worth a mention. Janus was the moon named for the two-faced god of beginnings—
    He whispered that to Linda, and got an appreciative nod. The Wilson girl wrote something too.
    “The radial spokes in the rings seem to be caused by very tiny particles, around the size of a wavelength of light. Also the process seems to be going on above the ring, not in it.”
    Radial spokes in the rings! They ought to disappear as the rings turned, because the inner rings were moving faster than the outer rings. They didn’t disappear. Weird news from everywhere in Saturn system. Some of Brooks’ colleagues would understand the explanations, when they came…
    Yet the press conference offered more than Brooks had expected. He had interviewed scientists before. It was the lack of answers that was interesting here.
    “We don’t know what that means.”
    “We wouldn’t like to say yet.”
    “The more we learn from Voyager, the less we know about rings.”
    “If we fiddle with the numbers a little we can pretty well explain why Cassini’s Divide is so much bigger than it ought to be.” Dramatic pause. “Of course that doesn’t explain why there are five faint rings inside it!”
    “If I’d had to make a long list of things we wouldn’t see, eccentric rings would have been the first item.”
    “Brad, what about braided rings?”
    “That would have been off the top of the paper.”
    Everyone up there looked happy, Brooks noted. Fun things were going on here. If Brooks didn’t have the background to appreciate them, who did?
    A newsperson asked, “Have you got any more on the radial spokes? I’d have thought that violated the laws of physics.”
    David Morrison from Hawaii answered, “I’m sure the rings are doing everything right. We just don’t understand it yet.” Brooks jotted it down. “Where I want to be,” Roger said, “is in a motel room with you.” They were walking the grounds of JPL: lawn, fountains, vaguely oriental rock gardens, a bridge, all very nice.
    “That was years ago,” Linda said. “And it’s all over.”
    “Sure?”
    “Yes, Roger, I’m sure. Now be good. You promised you would. Don’t make me sorry I came with you.”
    “No, of course I won’t,” Roger said. “It really is good to see you again. And I’m glad you’re happy with Edmund.”
    Are you? Linda wondered. And am I? Of course I am. I’m very happy with Edmund. It’s when he goes off and leaves me to take care of everything and I’m alone all the time and I see these goddam romantic perfume ads and things like that that I get unhappy about Major Edmund Gillespie. I wonder if the feminists did us any favors, letting us admit
