Explore the ionosphere! This region exists between Earth and space, and is home to the aurora, a variety of satellites (including the International Space Station), and communications signals. The ionosphere is sensitive to both Earth's weather from below and space weather from above, making it our interface to space. We're exploring the ionosphere with the upcoming launch of the ICON | NASA’s Goddard Space Flight Center

Figure 30.25  b shows how continuous refraction in the ionosphere enables long-distance radio communication. Waves launched at angles steeper than θdon't refract enough to return to Earth, so they propagate through the ionosphere and on to space. You can therefore conclude that a. all points between A and B receive stronger signals from A than point B receives. b. points between A and B can't receive signals from A via the ionosphere. c. the refractive index must become infinite at the maximum a
