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 “mothership” 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 mother-ship. It’s spaceship Earth, the home of over four billion people. This watercoated 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.
