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.

Universe Existance

Did you know?

"Critically, in the first few minutes of the universe's existance, the prevailing temperatures and pressures enabled subatomic particles to coelece into hydrogen and helium nuclei, with only the barest tracest of heavier elements. When the universe cooled further, 380,000 years later, electrons continued with the hydrogen and helium nuclei, forming neutral atoms and releasing the cosmic microwave background radiation (CMB)."
