WebDec 7, 2024 · Exactly 20 years ago today, Dec. 7, 2001, a Delta II rocket carrying NASA’s TIMED spacecraft took off from the California coast on a journey to study the least explored and understood part of Earth’s atmosphere — the upper climes 40-110 miles (60-180 kilometers) above the surface, where the Sun’s energy first enters Earth’s environment. WebThe ionosphere is the ionized part of the upper layer of the earth's atmosphere. The air molecules there are ionized by solar radiation. This layer of the atmosphere is a fairly good conductor, and radio waves are often "bounced" off the bottom of the ionosphere back toward the earth, in a process called skip or skywave propagation.
