IIIT WAS NOT d**k’S FAULT. It was just a tough break that no one had expected, planned for, guarded against. The planetoid was there beneath them; they would land on it. It was as simple at that. Only it wasn’t. Nor did they have any warning that the problem was more complex until it was too late to change their plans, too late to halt the irrevocable movements of a grounding spaceship. d**k should have known, of course. He was a spaceman; he had served two tricks on the Earth-Venus-Mars run. But all those planets were large; Eros was just a mote. A spinning top.... Anyway, it was after the final coordinates had been plotted, the last bank control unchangeably set, the rockets cut, that they saw the curved knife-edge of black slicing up over Eros’ rim. For a long moment d**k stared at it
