around the entire circumference of the hull and found only a thin silvery haze. The air as it leaked out formed a thin atmosphere around the hull, held there by the faint gravity of the ship's mass. Dust motes in the air, reflecting sunlight, were enough to hide any microscopic geyser spout. Before I re-entered the air lock I looked out into space, in the direction away from the sun. Out there, trailing far away, the air had formed a silver tail, I saw it faintly shimmering in the night. I was going to make a good comet.

I got back inside and stripped off the suit. Then I raised Lunar Base again and tapped out, HAVE INSPECTED HULL. RESULTS NEGATIVE. A few minutes later the reply came back, STAND BY FOR INSTRUCTIONS. For my morale.

I lighted another cigarette and thought about it some more. I looked around at the interior of my expensive, ten-foot coffin. I figured I would last for about another seventy-five hours. Of course I could take cyanide and get it over with. But this wouldn't be such a bad way to go. Within seventy-five hours the last of my reserve tanks would be empty. Then I would just wait for the rest of the air to leak out of the cabin. First I would lose consciousness with anoxia. I'd hardly even notice. Then as the pressure got lower my body fluids would begin to evaporate.

Once I had seen a mummy in a museum, it was some old prospector who had been lying in the Nevada desert for a hundred years or so. I was going to look like him, dried up, yellow, my teeth protruding in a grin, perfectly preserved. With no pilot, the ship would go into a cometary orbit around the sun. Maybe in a hundred years or so someone would come and take me back to a museum on earth.

I began to think about my wife, Sandy. I got out a piece of paper and wrote a long letter to her. I thought, maybe she'll even get to read it some day. Writing gave me something to do. I wrote about the time we had gone up to the Sierras together and slept in a sleeping bag at the edge of a four-thousand foot cliff. And about the times we had gone out in our cabin cruiser, the time we both nearly drowned. And asked about our daughter Wendy, who would be four now. I remembered part of an old poem:

Writing was all right, until I realized that I had begun feeling sorry for myself, and I was letting it get into the letter. I put the letter aside and wondered what else I could do to kill time. I got out some of the film plates I'd made of the surface of Mars. Of course I had transmitted them all to Lunar Base, but it would have been nice if I could have delivered the original plates. I studied them for a while but didn't find anything I hadn't seen before. Well, I had done my job at least. I had orbited Mars, I had the glory of being the first American to do that. I had dropped the instrument package and transmitted all the data I could get back to Lunar. My only failure would be in not bringing back the ship.

I remembered a conversation I'd had at the last International Space Symposium in Geneva. A buddy of mine and I had taken out one of the Soviet cosmonauts and got him drunk. He was a dignified sort of drunk, a Party member who told long, pointless Russian jokes with an unwavering, serious expression. He sat sideways on the bar stool, holding his glass of vodka between two fingers and staring straight ahead. He said one thing that I had never forgotten.

"Do you know why we are ahead of you in space?" he had said, staring with dignity at the tall blonde at a nearby table. "It is because of your bourgeois sentimentality. You do not like risking men. You build a skyscraper in New York to house some insurance company. Two or three construction workers are maimed or killed on the job. One of your coal mines collapses and fifty men are trapped. Yet, look. You are afraid of losing men in space because of what the people at home
