How do THEY get back to earth?!
Radio waves are reflected by many solid objects, such as wood, stone, and notably metal, allowing the use of microwaves in radar applications.Also importantly in broadcast radio, the ionosphere (an upper layer of the Earth's atmosphere) can bounce signals back down to locations beyond the line-of-sight horizon.
Yellow Back Radio Broke-Down was created in 1969.

Yes. The result is that some fraction of the radio energy, depending on its frequency and ranging from none of it to all of it, is bent back down to Earth. The rest continues on through the ionosphere into space.
The radiation emitted by sunspots ionizes the upper layers of the Earth's atmosphere. When that happens, radio waves (TV & radio) refract (bend) more in the ionization rather than shoot off into outer space as much. The radio waves by bending back to Earth travel much farther than if they just went straight. In the right conditions, these bent radio waves can bounce up off the Earth's surface and refract again in the ionized layers of the atmosphere, coming back down. In this ways, radio waves can travel long distances. The result is, that these long-distance radio waves come back to Earth where there are other radio and TV stations using the very same frequencies, and the long-distance radio waves interfere with the local programing.
A propagation delay is the amount of time it takes radio waves to travel from the surface of the Earth to the satellite and then back down to the Earth. The calculation of the delay is based upon the altitude and position of the satellite systems.
Connect the wiring harness on the back of your new radio. Slide the radio into the radio slot. Tighten down the radio retaining screws.
Gravity (the Earth's pull) drags your body back down.
On the back of the Radio. On the connector there should be a tab that moves up and down. With the connector in the up position, Connect connector to back of radio and press down on the tab. By doing that, it should slide right in. Don't forget to plug in the antennae.
Down to Earth - 1984 Back to Basics 1-3 was released on: USA: March 1984
The force of gravity pulls it back down to Earth.
