Dinosaurs conquered the land at enormous sizes, but strangely, they almost never evolved into truly tiny animals. New research suggests that physiology alone can’t explain this missing miniature end of the dinosaur spectrum—and that early mammals may have been partly responsible. While dinosaurs kept mammals from becoming large, small mammalsContinue Reading

Granular Mechanics and Regolith Operations (GMRO) Overview The Granular Mechanics and Regolith Operations Laboratory (GMRO) studies the mechanics of materials in a launch pad environment, especially the mechanics of soil at Lunar and Martian spaceports; how to excavate the soil to prepare berms, landing pads, and roads; how to modelContinue Reading
