Jan 13, 2021 Radio waves in the Jupiter system aren't new to science - similar decametric radio emissions (decametric meaning wavelengths in the tens of 


Ultra high energy (UHE) particles of cosmic origin impact the lunar regolith and produce radio signals through the Askaryan effect, signals that can be detected 

Short answer: Yes, you can, as radio waves move at the speed of light in a vacuum. In practice, however, scientists typically measure this distance with lasers instead of radio waves. Here’s why: During the Apollo missions, NASA astronauts left re 2021-01-09 This report presents a theoretical discussion of the statistical properties of radio waves reflected from the moon. The discussion is based on the assumption of a large number of scattering areas simultaneously contributing to the signal.

Jan 11, 2021 The Juno spacecraft orbiting Jupiter discovered an FM radio signal coming from the moon Ganymede. The find is a first-time detection from the  Jan 11, 2021 FM radio signal found coming from Jupiter moon SALT LAKE CITY (KTVX) – The Juno spacecraft orbiting Jupiter has discovered an FM radio  This report presents a theoretical discussion of the statistical properties of radio waves reflected from the moon. The discussion is based on the assumption of a  Jan 18, 2021 NASA's Spacecraft Juno Detects FM Radio Signals From Jupiter's Moon Ganymede It has recently come to light that the National Aeronautics  Jun 27, 2019 The famous video of Apollo 11 began as a faint, high-frequency transmission from the lunar lander. By the time the signal reached Earth it was  Oct 26, 2018 Radio waves can't actually pass through the Moon - which is the reason why it's difficult to communicate with astronauts on the Moon's far side,  On this day in tech history, Project Diana bounced radio signals off the moon and received the reflected signals, not only proving that artificially-created signals  Earth-Moon-Earth, EME or Moonbounce is a form of radio propagation used by radio amateurs and others for global communications on frequencies above 144   The moon is a relatively poor reflector of electromagnetic rays at any wavelength, including radio waves. Its surface is irregular, and it scatters, rather than focusing,   Earth–Moon–Earth communication (EME), also known as Moon bounce, is a radio communications technique that relies on the propagation of radio waves from  Jan 12, 2021 Now it's come to light Juno has discovered an FM signal emanating from one of the gas giant's moons, Ganymede.

The signal, seen for just five seconds as the spacecraft screamed past Ganymede at 180,000 KPH (nearly 112,000 MPH), was likely the result of electrons amplifying radio waves, in a process called

Alessandro Ardito From Moon TERF to Mean Ecliptic RF .. chromatic radio signal (for Mercury, λ = 3.5 cm) from transmitting station while echoes are  large-amplitude HF radio waves and the ionosphere, Geophys.

Image at the top of the page shows radio waves from our galaxy, the Milky Way, reflecting off the surface of the Moon and observed by the Murchison Widefield Array radio telescope located in

This attracted the attention of Donald Menzel. In the lunar echo experiment (more properly called a lunar bi-static radar experiment), the Air Force/Navy High Frequency Active Auroral Research Program (HAARP) high power transmitter, located near Gakona, Alaska, launched high power radio waves toward the moon. Radio communication on Earth is strongly dependent upon the ionosphere - a layer of the atmosphere comprised of charged particles sympathetic to radio energy. Luna does not have an ionosphere but lunar dust levitates. The dust is ionized by the Sun. What I am curious about. Is long range radio communication possible on the lunar surface?

Moon radio waves

(Compare that to the wavelengths of X-rays.)The Sun is the brightest source of radio waves in the sky. Ultra high energy (UHE) particles of cosmic origin impact the lunar regolith and produce radio signals through Askaryan effect, signals that can be detected by Earth based radio telescopes. We calculate the expected sensitivity for observation of Far side of the moon offers quiet place for telescopes. To peer back to the universe's earliest years will need sensitive telescopes in a place where Earth's ionosphere and radio chatter cannot Radio waves propagate in vacuum at the speed of light c, exactly 299,792,458 m/s. Propagation time to the Moon and back ranges from 2.4 to 2.7 seconds, with an average of 2.56 seconds (distance from Earth to the Moon is 384,400 km).

Here are three "radio pictures" showing: How was it possible for astronauts to send back tv/radio signals to earth from the moon? I have just been teaching my son about waves behavior and understand that radio waves are reflected back to earth from the ionosphere. As far as I know microwaves were not used for communication purposes back then. The Moon Radio module allows you to access the entire Moon broadcast. The modern-day ether is cluttered with a multitude of transmissions, from mobile phone conversations beaming every which way through the lower atmosphere, to the latest lubricious single titillating us through our car radios.
