I went back to the problem of setting our sixteen thousand tons of ship onto the rock.It wasn't much of a rock. Jefferson is an irregular-shaped asteroid about twice as far out as Earth. It measures maybe seventy kilometers by fifty kilometers, and from far enough away it looks like an old mud brick somebody used for a shotgun target. It has a screwy rotation pattern that's hard to match with, and since I couldn't use the main engines, setting down was a tricky job.Janet wasn't finished.

We fight a lot, but that's our private business.The attitude jets popped. "Hear this," I said. "I think we're coming in too fast. Brace yourselves." The jets popped again, short bursts that stirred up dust storms on the rocky surface below.
