【正文】 direction. He seemed unhappy rather than disgruntled, and she felt sorry for him. Once, their eyes met. Susan couldn39。t be sure, but she thought she saw a slight response before he looked down. A quick breath of fresh air, then the youngsters returned to the lecture hall. Ben Bellingham was waiting for them. Please take your seats in the front row. OK, who cares about conservation? Hands up. Everybody reacted. Bellingham pointed to Vanessa. Why? he demanded. Vanessa opened her mouth in surprise. Er ... The naturalist repeated his question, more gently. Why, Vanessa? Why should you care what happens in Africa, the Amazon, the Antarctic or anywhere else that isn39。t your home? What39。s it got to do with you? He nodded encouragingly. Well? Vanessa stuc k out her chin. Animals have as much right to be on earth as we have. Morethey were here first. And if we39。re the most intelligent creatures, the only ones that are moral, it39。s our duty to look after the environment. Besides, nobody owns the world. All living things are part of nature. So in a way nature owns us ... Blushing, Vanessa tailed off. Without thinking, Susan started to clap. Bellingham: Bravo! You convinced meand at least one other person. Now Susan went pink. Walking along the row, Bellingham added: Anybody else want to speak up for conservation? Yes, Gary. Well, Mr. Bellingham, I was just wondering about the Amazon. The way the trees are being cut downfifty thousand acres a day. Don39。t half of all plant and animal species live there? The naturalist leaned towards him. Quite right. Oh, and call me Ben. Gary went on: I39。ve read that a lot of industry, agriculture and medicine is based on jungle productsrubber, coffee, bananas, quinine and so on. Also that the Amazon is a botanical treasure house we39。ve barely begun to explore. It needs to be protected for everyone39。s sake. Another thingpeople are upsetting the world climate by felling those trees ... Bellingham chipped in. Right again, Gary. But the situation is even worse than that, I39。m afraid, as you39。ll see for yourselves on this trip. Norman put his hand up. No one has mentioned the gene pool. If the number of species keeps falling, the pla may not be able to evolve to meet changing conditionsand life could die out. Ben rubbed his chin. Certainly done your natural history homework, haven39。t you? He strode to the table behind him, on which stood a glass jar. Turning, he said: I think you and I agree conservation is wor thwhile. There was a loud murmur of assent. Bellingham picked up the jar, full of cloudy liquid. Something was floating in it. Know what this is? He unscrewed the lid and, taking a pa ir of tweezers from his shirt pocket, fished out the mysterious object. Open your hand, he said to Susan. She squealed as he dropped what he was holding into her palm. Slimy and spotted ... frog39。s legs! Won39。t hurt you, he reassured her. Just the legs of some unlucky Indian bullfrog which didn39。t hop off in time to save itself. er suit was bulky and tight. it murmured at her while the radio hissed quietly. it smelled fortably like herself, and like hospital plastic and fresh oxygen. Ringmaster was an elongated structure consisting of two main sections joined by a hollow tube three meters in diameter and a hundred meters long. Structural strength for the tube was provided by three posite girders on the outside, each of which transmitted the thrust of one engine to the life system balanced on top of the tube. At the far end were the engines and a cluster of detachable fuel tanks, hidden from sight by the broad plate of the radiation shield which ringed the central tube like the rat guard on the m ooring line of an oceangoing freighter. The other side of that shield was an unhealthy place to be. On the other end of the tube was the life system, consisting of the science module, the control module, and the carousel. Control was at the extreme front end, a coneshaped protuberance rising from the big coffee can that was SCIMOD. It had the only windows on the ship, more for tr adition than practicality. The Science Module was almost hidden behind a thic ket of instrumentation. The highgain antenna rose above it all, perched on the end of a long stalk and trained on Earth. There were two radar dishes and five telescopes, including Gaby39。s 120centimeter Newtonian. Just behind it was the carousel: a fat, white flywheel. It rotated slowly around the rest of the ship, with four spokes leading up from the rim. Strapped to the central stem were other items, including the hydroponics cylinders and the several ponents of the lander: life system, tug engine, two descent stages and the ascent engine. The lander had been intended for exploring the Saturn moons, in particular Iapetus and Rhea. After Titanwhich had an atmosphere and was therefore unsuited for exploration this tripIapetus was the most interesting body in the neighborhood. Until the 198039。s, it had been significantly brighter in one hemisphere, but it had changed over a twenty year period until its albedo was nearly uniform. Two troughs in the graph of luminosity now occurred at opposite points on its orbit. The lander had been designed to discover what caused it. Now that trip had been scrapped in the face of the much more pelling object called Themis. Ringmaster resembled another spaceship: the fictional Discovery, the Jupiter probe from the classic movie 2021.. A Space Odyssey. It was not surprising that it should. Both ships had been designed from similar parameters, though one sailed only on celluloid. Cirocco was EVA to remove the last of the solar reflection panels which wrapped the life system of Ringmaster. The problem in a space vehicle is usually one of disposing of excess heat, but they were now far enough fro
