Have you ever dreamed of traveling through space? The prospects sound exciting to most people.
Amazingly, we are already traveling through space—but without being aware of it! Planet earth can correctly be compared to a giant spacecraft carrying on board more than 6 billion people and billions more animals and plants. American scientist Buckminster Fuller coined the fitting term "Spaceship Earth" to describe our planet.
We are truly hurtling through space on this giant spacecraft called earth—at the incredible speed of 65,000 miles per hour! This is far faster than man's speediest aircraft. At the same time, this space vehicle is spinning at more than 1,000 miles per hour. Every year we complete an entire circuit around the sun—a journey of more than half a billion miles!
Yet perhaps the most amazing aspect of our voyage is we don't feel the trip at all. Certainly as we travel in a car at 50 miles per hour, we can sense the velocity and see the scenery go by. But the paradox is, once we get out of the car and sit down, everything on the ground seems at rest—yet we are still traveling at an incredible speed through space.
If we finish our life's journey with an average life span, we will have traveled around the sun some 76 times, and completed a trip of more than 38 billion miles—the equivalent of traveling several times to the planet Pluto and back! All of this without ever feeling the velocity or being aware of the trip itself.
This is just one of the incredible features of our remarkable spaceship .
