For many centuries, people gazed in awe of birds at play on clouds. Authors wrote of the thrill we seek within flight on the back of dragons or within the strength of our minds. Moments of joy are described as floating with wings of an angel. Leonardo drew his ideal flying machine in his invention sketchbook. What did the birds feel as they soared through unknown territory? What was it that they have found and we could not achieve?

Little boys tied string onto homemade kites, knowing that paper and sticks would experience a thrill they wished to sense. Some kites formed a shape of a box. As the box kites became more sophisticated, the Wright Brothers thought of a sophisticated idea. They put a tiny light motor and a box kite structure together. These brothers became the first to fly. They achieved what everyone imagined.

Human nature seeks more learning. Though we have achieved flight on Earth, we have looked beyond the sky at the lit up stars. At night a dark cloth with tiny little holes that let a little light spill in, covers the earth. We seek to uncover. We seek to know. We build and build, in order to learn and learn. What do the stars feel as they move through unknown territory? What was it that they have found and we cannot see?

Today, space exploration grows as our thirst for knowledge grows. Special equipment is used to record and understand, such as space shuttles and satellites. More ideas are developed everyday to conquer the unknown.
