Project Diana, named for the Roman moon goddess Diana, was a project of the US Army Signal Corps to bounce radio signals off the moon and receive the reflected signals. Roman mythology, or more appropriately Latin mythology, refers to the mythological beliefs of the Italic people inhabiting the region of Latium and its In Mythology, a lunar deity is a God or Goddess associated with or symbolizing the moon see Moon (mythology. In Roman mythology, Diana was the goddess of the hunt, being associated with wild animals and woodland and also of the Moon. Today called EME (Earth-Moon-Earth), this was the first attempt to "touch" another celestial body. Earth-Moon-Earth, also known as moon bounce, is a radio communications technique which relies on the propagation of radio waves from an Earth -based transmitter directed s are significant physical entities, associations or structures which current Science has confirmed to exist in Space. From a laboratory at Camp Evans (part of Fort Monmouth), near Wall Township, New Jersey, a large transmitter, receiver and antenna array were constructed for this purpose. Camp Evans, New Jersey is a former military base associated with Fort Monmouth. Fort Monmouth is an installation of the Department of the Army in Monmouth County New Jersey Wall Township is a Township in Monmouth County, New Jersey, United States. New Jersey ( is a state in the Mid-Atlantic and Northeastern regions of the United States. For biologic transmitters see Transmitter substance. A transmitter is an electronic device which usually with the aid of an antenna The transmitter, a highly modified SCR-271 radar set from World War II, provided 3,000 watts at 111. Radar is a system that uses electromagnetic waves to identify the range altitude direction or speed of both moving and fixed objects such as Aircraft, ships World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including The watt (symbol W) is the SI derived unit of power, equal to one Joule of energy per Second. 5 MHz in 1/4 second pulses, and the antenna (a "bedspring" dipole array) provided 24 dB of gain. The hertz (symbol Hz) is a measure of Frequency, informally defined as the number of events occurring per Second. In physics there are two kinds of dipoles ( Hellènic: di(s- = two- and pòla = pivot hinge An electric dipole is a The decibel ( dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity (usually power or intensity relative to Reflected signals were received about 2. 5 seconds later, with the receiver compensating for Doppler modulation of the reflected signal. In Telecommunications, modulation is the process of varying a periodic Waveform, i The antenna could be rotated in azimuth only, so the attempt could be made only as the moon passed through the 15 degree wide beam at moonrise and moonset, as the antenna's elevation angle was horizontal. Azimuth ( is a mathematical concept defined as the angle usually measured in degrees (° between a reference plane and a point. The elevation of a Geographic location is its height above a fixed reference point often the mean sea level. About 40 minutes of observation was available on each pass as the moon transited the various lobes of the antenna pattern. In the field of antenna design the term radiation pattern most commonly refers to the directional (angular dependence of radiation from the antenna or other The first successful transmission was made on 10 January 1946 at 11:58am local time. Events 49 BC - Julius Caesar crosses the Rubicon, signaling the start of civil war. Year 1946 ( MCMXLVI) was a Common year starting on Tuesday (link will display full 1946 calendar of the Gregorian calendar.
Project Diana marked the birth of the US space program, as well as that of radar astronomy. The National Aeronautics and Space Administration ( NASA, ˈnæsə is an agency of the United States government, responsible for the nation's public space program Radar Astronomy is a technique of observing nearby astronomical objects by reflecting Microwaves off target objects and analyzing the echoes It was the first demonstration that artificially-created signals could penetrate the ionosphere, opening the possibility of radio communications beyond the earth for space probes and human explorers. The ionosphere is the uppermost part of the atmosphere, distinguished because it is Ionized by solar radiation A space probe is a scientific Space exploration mission in which a Robotic spacecraft leaves the Gravity well of Earth and approaches the It also established the practice of naming space projects after Roman gods, e. g. , Mercury and Apollo.

Today, the Project Diana site is maintained by the Ocean-Monmouth Amateur Radio Club, where they sometimes operate an amateur radio station as a special event. Ocean Township is a Township located in east central Monmouth County, New Jersey. Amateur radio, often called ham radio, is both a Hobby and a service in which participants called "hams" use various types of Radio communications
