"I'm an explorer, all right, Crosno," I said. "I've taken risks, and I'm willing to take more. But if you think I'm going to climb into that contraption, and be blown off to the moon—" The hurt on his gaunt bloodless face stopped my voice. "Not the moon, Horn." A gesture of his long arm carried my gaze from the mottled lunar disk, westward to the evening star. "To Venus," he said. "First." I caught my breath, staring in awe at the white planet. "The range of the Astronaut," he said, "should enable you to reach there, land, spend several months in exploration, and time your return to reach Earth safely at the next conjunction—if you are very lucky." His dark, magnetic eyes probed me. "What do you say, Horn?" "Give me a little while," I said. "Alone."

She looked at me, with wide eyes that were violet-black, and filled with an urgent dread. She half rose, in her thick mantle of dark, red-gleaming hair. And her voice spoke to me from the crystal casket, saying: "Go, Barry Horn! You must go." In another instant, the vision
