NASA: July 2025

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.

Space

"Space isn’t empty at all."https://www.earth.com/news/first-direct-image-cosmic-web-filaments-hidden-highways-universe-framework/

Asteroid

"Twenty years ago, the US Congress instructed NASA to find 90% of near-Earth asteroids threatening Earth."https://charmingscience.com/an-invisible-threat-swarm-of-hidden-city-killer-asteroids-around-venus-could-one-day-collide-with-earth/

Speeding Planet

"Our planet is speeding up, yes, like Hamilton when he reaches a corner. Astronomers are investigating because, since 2020 (and for still unknown reasons), the Earth has been spinning on its axis faster than usual, and the next record is about to happen."

Paradoxes

"Paradoxes can be scary things in science, as they almost always represent some fundamental misunderstanding of reality and the universe."https://www.popularmechanics.com/science/a65178424/memory-cells/

Quadrillion Solar Masses

"Move over, Shapley Superstructure; there’s a new champion in town. Astronomers have identified a cosmic filament of matter so vast that it stretches about 1.3 billion light-years – approximately 7.6 sextillion miles – from end to end."https://www.earth.com/news/quipu-new-largest-structure-in-universe-weighs-staggering-200-quadrillion-solar-masses/
