人类自古向往天堂,神话故事、科学幻想多如牛毛。当今人类面临人口增长、能源危机、食物短缺等重大问题。飞出地球,去开发宇宙空间,就成为全人类重大的科研课题。自1957年苏联发射第一颗人造卫星以来,人类先后向太空成功发射了各种卫星、飞船探测器,并顺利地登上了月球。科学家们预计在21世纪,太空将会诞生形形色色的空间产业。太空宾馆下一世纪,太空将会成为人类的又一旅游胜地。不久前,日本清水公司与美国贝尔和特罗蒂公司的专家设计了一种宇宙宾馆。它将处在地球上空450千米的高度。形状犹如直径140米的大型游艺场,房间可供大约100名旅游者住宿。为了使这些旅游者
Humans have longed for paradise since ancient times. There are many mythological stories and scientific illusions. Humanity now faces major issues such as population growth, energy crisis, and food shortages. Flying out of the earth to develop space has become a major research project for all humanity. Since the launch of the first artificial satellite by the Soviet Union in 1957, mankind has successfully launched a variety of satellites and spacecraft probes into space and successfully landed on the moon. Scientists expect that in the 21st century, space will have a variety of space industries. Space Hotel In the next century, space will become another resort for mankind. Not long ago, experts from Japan’s Shimizu and Bell and Trotti designed a space hotel. It will be at a height of 450 kilometers above the Earth. It is shaped like a large amusement park with a diameter of 140 meters. The room can accommodate approximately 100 tourists. In order to make these tourists
