National Aeronautics and Space Administrion

Since its inception in 1958, NASA has accomplished many great scientific and technological feats in air and space. NASA technology also has been adapted for many nonaerospace uses by the private sector. NASA remains a leading force in scientific research and in stimulating public interest in aerospace exploration, as well as science and technology in general. Perhaps more importantly, our exploration of space has taught us to view Earth, ourselves, and the universe in a new way. While the tremendous technical and scientific accomplishments of NASA demonstrate vividly that humans can achieve previously inconceivable feats, we also are humbled by the realization that Earth is just a tiny "blue marble" in the cosmos. Check out our "Thinking About NASA History" folder online as an introduction to how history can help you.

A Tiny Percentage Of Energy Released by The Sun Reaches Earth


"We know that the Sun releases massive amounts of energy on a daily basis. Our world is warmed and kept alive by this energy, and we’re fairly close, so we must be receiving a lot, right? Not exactly. In fact, the total amount of energy the Earth receives from the Sun is just about one one-billionth of the total amount of energy the Sun generates. This is a teeny tiny fraction, and yet if we could harness it all we would be able to power the entire world many times over."
