近日,美国宇航局长迈克尔·格里芬已正式接受中国航天局的邀请,即将对中国进行正式访问,两国专家将广泛探讨包括探月在内的航天领域的合作的可能性。随着航天热在两国不断升温,美国科学家奇妙的太空电梯计划再一次成为人们议论的焦点,该计划一旦实施,无疑彻底改变人类涉足太空的方式,届时体验太空感觉就像度假郊游一样,轻松愉快。太空电梯理论上已没有问题,草图已经拟就。也许是15年,也许是30年,美国科学家在赤道附近建成近10万千米的太空电梯,它矗立在一座25千米高的巨大平台上。它的轨道骨架就是碳纳米管合成的超级材料。它最多可承载200多部电梯,每小时可运行200千米,7天后抵达同步轨道。届时,向国际空间站运送货物的成本由1千克约1.1万美元,降至110美元。设计者估计,谁抢先建成太空电梯,谁将至少统治外太空100年。
Recently, NASA Michael Griffin has formally accepted the invitation of China Space Administration and is about to pay an official visit to China. Experts from both countries will extensively explore the possibility of cooperation in the aerospace field, including lunar exploration. As aerospace fever continues to heat up in both countries, the wonderful space elevator program of the U.S. scientists once again becomes the focus of discussion. Once implemented, the plan will undoubtedly completely change the way human beings get involved in space, and experience the feeling of space in the same way as if you were on a vacation outing happy. Space elevator theory has no problem, the sketch has been proposed. It may be 15 years, maybe 30 years. U.S. scientists built a nearly 100-kilometer space elevator near the equator. It stands on a huge platform of 25 kilometers in height. Its orbital skeleton is a supermaterial for the synthesis of carbon nanotubes. It can carry up to 200 elevators, can run 200 kilometers per hour, arrived in 7 days after the synchronous orbit. By then, the cost of transporting the cargo to the ISS dropped from about $ 11,000 to less than $ 110 a kilogram. Designers estimate that who first built a space elevator, who will rule at least 100 years of outer space.
