WebMar 31, 2024 · The Short Answer: Spacecraft send information and pictures back to Earth using the Deep Space Network (DSN), a collection of big radio antennas. The antennas also receive details about where the spacecraft are and how they are doing. NASA also uses the DSN to send lists of instructions to the spacecraft. Lower frequency (between 30 and 3,000 kHz) vertically polarized radio waves can travel as surface waves following the contour of the Earth; this is called ground wave propagation. In this mode the radio wave propagates by interacting with the conductive surface of the Earth. The wave "clings" to the surface and thus follows the curv… song lyrics badlands bru

WebHigh in the stratosphere, about 32 kilometers (20 miles) above the Earth's surface, the conditions are just right to maintain a concentration of 8 parts per million of ozone. That's a good thing because that ozone strongly absorbs ultraviolet radiation that would otherwise create conditions inhospitable for ... WebHow do radio waves carry information? The basic principle is simple. At one end, a transmitter “encodes” or modulates messages by varying the amplitude or frequency of the wave – a bit like Morse code. At the other, a receiver tuned to the same wavelength picks up the signal and ‘decodes’ it back to the desired form: sounds, images, data, etc.
