"That's it," she said, shrugging. "Something ventured but nothing found. So I asked to be returned here."

"It's got you, too, hasn't it?"

Her face became serious for the first time. "Certainly it's got me. It's got all of us. Do you think we'd stay out here otherwise?"

"Anything new turned up?"

Elaine shook her head. "Nothing you haven't seen in the reports. Which means nothing, really."

He lapsed into silence and watched the frozen landscape slide by as the car raced along Titan's only highway. They crossed a bleak, frozen plain, bluish-white in the dim twilight from the distant Sun. The stars twinkling in the dark sky overhead made the barren scene look even colder. The road climbed across a row of hills, and as they made a turn around the highest bluff, Saturn came into view.

No matter how many times Lee had seen the planet, it had always thrilled him. Now, five years later, it was still an experience. Three times larger than the full moon as seen from Earth, daubed with brilliant yellow, red and orange stripes, and circled about its middle by the impossible-looking rings, Saturn hung fat and low on the horizon, casting shadows stronger than the Sun's.

"It's a compensation, isn't it?" Elaine said.

Soon they were down on the plain again, but now it was a shattered, broken expanse of jagged rock and ice. A greenish methane cloud drifted over the face of Saturn, and Lee finally turned his eyes away.

"You can see the towers from here," Elaine reminded him.
