Text 1
①In May 1989, space shuttle “Atlantis” released in outer space the space probe “Megallan,” which is now on her 15-month and one-billion-kilometer flight to Venus. ②A new phase in space exploration has begun.
①The planet Venus is only slightly smaller than Earth; it is the only other object in the solar system, in fact, that even comes close to earth’s size. ②Venus has a similar density, so it is probably made of approximately the same stuff, and it has an atmosphere, complete with clouds. ③It is also the closest planet to earth, and thus the most similar in distance from the sun. ④In short, Venus seems to justify its long-held nickname of “earth’s twin.”
①The surface temperature of Venus reaches some 900F. ②Added to that is an atmospheric pressure about 90 times Earth’s: High overhead in the carbon dioxide (CO2) that passes for air is a layer of clouds, perhaps 10 to 20 miles thick, whose little drops consist mostly of sulfuric acid (H2SO4). ③Water is all but nonexistent.
①Born with so many fundamental similarities to earth, how did Venus get to be so radically different: It is not just an academic matter. ②For all its extremes, Venus is a valuable laboratory for researchers studying the weather and climate of earth. ③It has no earth’s oceans, so the heat transport and other mechanisms are greatly simplified. ④In addition, the planet Venus takes 243 earth-days to turn once on its axis, so incoming heat from the sun is added and distributed at a more leisurely, observable pace.
