lähiavaruudesta
Lähiavaruus, or near space, refers to the region of Earth's atmosphere above where conventional aircraft typically fly but below the altitude of orbiting satellites. This transitional zone is generally considered to extend from approximately 20 kilometers to 100 kilometers above the Earth's surface. Within this domain, the atmosphere is significantly thinner than at lower altitudes, but still dense enough to provide some aerodynamic lift and drag.
The scientific study of lähiavaruus is crucial for understanding atmospheric phenomena, weather patterns, and the interaction
Several nations and private companies are actively exploring the potential of lähiavaruus for various applications. These
