It has recently become practical to use the radio emission of the moon and planets as a new source of information about these bodies and their atmospheres.

The results of present observations of the thermal radio emission of the moon are consistent with the very low thermal conductivity of the surface layer which was derived from the variation in the infrared emission during eclipses ( e.g., Garstung, 1958 ).

Observations of the radio emission of a planet which has an extensive atmosphere will probe the atmosphere to a greater extent than those using shorter wave lengths and should in some cases give otherwise unobtainable information about the characteristics of the solid surface.

The observed intensity of the radio emission of Venus is much higher than the expected thermal intensity, although the spectrum indicated by measurements at wave lengths near 3 cm and 10 cm is like that of a black body at about 600-degrees.

For the case of Jupiter, the radio emission spectrum is definitely not like the spectrum of a black-body radiator, and it seems very likely that the radiation reaching the earth is a combination of thermal radiation from the atmosphere and non-thermal components.

No attempts to measure the radio emission of the remaining planets have been reported, and, because of their distances, small diameters, or low temperatures, the thermal radiation at radio wave lengths reaching the earth from these sources is expected to be of very low intensity.

In spite of this, the very large radio reflectors and improved amplifying techniques which are now becoming available should make it possible to observe the radio emission of most of the planets in a few years.

The study of the radio emission of the moon and planets began with the detection of the thermal radiation of the moon at 1.25-cm wave length by Dicke and Beringer ( 1946 ).

They deduced from their measurements that the radio emission from the whole disk of the moon varied during a lunation in a roughly sinusoidal fashion ; ;

and that the maximum of the radio emission came about 3-1/2 days after Full Moon, which is again in contrast to the infrared emission, which reaches its maximum at Full Moon.

The infrared emission could then be assumed to originate at the surface of the moon, while the radio emission originates at some depth beneath the surface, where the temperature variation due to solar radiation is reduced in amplitude and shifted in phase.

This is much smaller than the highest resolution of even the very large reflectors now under construction, and consequently the radio emission of different regions of the disk cannot be resolved.

Other than this very significant result, most of the information now available about the radio emission of the planets is restricted to the intensity of the radiation.

The radio radiation of the sun which is reflected from the moon and planets should be negligible compared with their thermal emission at centimeter wave lengths, except possibly at times of exceptional outbursts of solar radio noise.

Such high-resolution observations as these are needed at several wave lengths in order that the radio emission of the moon can be properly interpreted.

Originating in the Superman radio show series, the material is usually shown as having been created from the radioactive remains of Superman's native planet Krypton, and generally has detrimental effects on Superman and other Kryptonians.

He and Superman had originally gone to the world to have a proper fight as Superman did not want to appear cowardly after Luthor over a radio challenged him to a fight, as this planet had a red sun meaning Superman lost his powers there.

It carried a complement of experiments to probe Venus ' atmosphere with radio waves, scan its brightness in ultraviolet light, and sample the solar particles and magnetic field fluctuations above the planet.

Mariner 3 ( together with Mariner 4 known as Mariner-Mars 1964 ) was one of two identical deep-space probes designed and built by Jet Propulsion Laboratory ( JPL ) for NASA's Mariner Mars 1964 Project that were intended to conduct close-up ( flyby ) scientific observations of the planet Mars and transmit information on interplanetary space and the space surrounding Mars, televised images of the Martian surface and occultation data of spacecraft radio signals as affected by the Martian atmosphere back to Earth.

Mariner 5 ( Mariner Venus 1967 ) was a spacecraft of the Mariner program that carried a complement of experiments to probe Venus ' atmosphere by radio occultation, measure the hydrogen Lyman-alpha ( hard ultraviolet ) spectrum, and sample the solar particles and magnetic field fluctuations above the planet.

By radio Rodricks describes a vast burning column ascending from the planet.

During imaging, the radio altimeter would be lined up with the center of the planet ( local vertical ) and the SAR would be looking off to the side at 10 degrees.

The purpose of the mission had been to locate the source of radio signals that Spectrum had detected emanating from the planet.

The reported radio emissions are not of the primary electromagnetic Schumann modes, but rather of secondary modulations of the nonthermal microwave emissions from the planet at approximately the expected Schumann frequencies, and have not been independently confirmed to be associated with lightning activity on Mars.

Also, instead of remaining in the asteroid belt, Ms. Frizzle uses her jet pack to fly off to another planet and provides the kids with clues as to her location via the radio on the bus.

She has been monitoring radio transmissions from the planet and informs them that the Empire's spokesman has tried to ridicule the belief of these worshippers the entire time, but has utterly failed.

The back side of this ridge also lies within the radio shadow of the Earth, and it has been suggested as a site for a radio telescope because the radio noise from our planet would be blocked.

On a shelf in the office behind the counter was a small radio dialed permanently on a station which broadcast only vulgar commercials and cheap popular music.

The need for monitoring became greater when radio was adopted for military signaling.

Years ago this was true, but with the replacement of wires or runners by radio and radar ( and perhaps television ), these restrictions have disappeared and now again too much is heard.

Finally, Mama did mention to Mrs. Coolidge that she felt sorry for the little dogs, and then Mrs. Coolidge decided to leave the radio on for them while she was gone, even though her husband disapproved of the waste of electricity.

It was a district of small factories and loft buildings and occasional tenements, and he could see the police radio car as he rounded the corner and slammed on the brakes.

But instead of chatter there was a null, like on the radio direction finder.

The description of the car was immediately broadcast throughout Southern Maryland on police radio.
