到下世纪初叶,人类可能会在月球上建立起永久性的基地,并将环绕火星和金星进行驾驶飞行,并开始利用轨道站来研究木星。 人类将成功地试用月球上的原材料在月球上进行土木施工、发电或利用月球岩石中的结晶水制取饮用水。如果能发现碳化钙的话,人类则有可能在那里利用太阳能装置来制造氧。 人类将开始用月球上的原料来生产火箭发动机用的燃料。在火星和金星的周围以及木星的卫星上,将建立永久性的研究站。在21世纪,人 By the beginning of the next century, mankind may set up a permanent base on the moon and fly piloting Mars and Venus, and begin to use orbital stations to study Jupiter. Humans will successfully try out the raw materials on the moon to carry out civil works on the moon, to generate electricity or to use the crystal water in lunar rocks to make potable water. If calcium carbide can be found, it is possible for humans to use solar energy to make oxygen there. Mankind will begin to use the raw materials on the moon to produce rocket engine fuel. Around Mars and Venus, as well as Jupiter’s satellites, a permanent research station will be established. In the 21st century, people
