Space
Our Future in Space: It Has Already Begun!
We are all space travelers. But we’ve stayed close to home until now. One day, we may leave our “mothership” Earth to make our home among the stars。
A giant, spherical “spaceship”， about 8,000 miles in diameter, is speeding through the solar system right now. It is cruising at an incredible 66,600 miles per hour。
It’s not a giant, Star Wars mothership. It’s spaceship Earth, the home of over four billion people. This watercoated spaceship has been traveling through the universe for about five billion years. Only within the past 25 years, however, have some of its passengers broken free of Earth’s gravity。
But 25 years from now, many people, including you, might live in an orbiting space station 200 miles above the Earth。
Space Cities
Scientists have already designed special space factories. These factories will take advantage of the absence of gravity (zero gravity) to produce everything from life-saving drugs to perfect ball bearings。
Other scientists have designed space colonies, complete with farms, schools, and artificial day and night. Hundreds, or even thousands, of people will live, work, play—even go to school, far above the Earth。
Our conquest of space, of course, has already begun. We have explored part of the Moon, sent robot spaceships onto the surface of Venus and Mars, and aimed space probes past the planets of Jupiter and Saturn。
Last June, one robot ship, Pioneer 10, left our solar system forever. And astronauts from both the Soviet Union and the United States have lived in space stations。
