When the different NASA spacecraft such as Voyager, Mars Reconnaissance Orbiter (MRO), Lunar Reconnaissance Orbiter (LRO), and MESSENGER (Mercury Surface, Space Environment, Geochemistry and Ranging), among others, currently exploring the universe send messages to Earth, they do so through the transmission of microwaves, a type of electromagnetic wave, shorter in wavelength than that of radio, that can travel far distances and penetrate through the atmosphere. While longer microwaves are used to cook our food, shorter microwaves are used for satellite communication to Earth, for radar systems such as the Doppler weather radar, for GPS navigation, and even for wireless internet signals.
