Analysis of the Radio Astronomy Explorer lunar orbit mission
Astrodynamics Conference, 1972The second Radio Astronomy Explorer spacecraft (RAE-B) is planned to be inserted into lunar orbit in 1973. The transfer trajectory design, lunar orbit selection and launch opportunities are developed in relation to the spacecraft mass properties, propulsion capability and the scientific, environmental and engineering constraints.

Introduction to the Techniques of Interferometry and Lunar Occultation in Radio Astronomy
Resonance, 2018Radio telescopes allow a 24 × 7 observation time window of those regions of the space which appear dark in the visible region. But, the major problem with a single radio telescope is its poor resolution. In this article, the method of interferometry in radio astronomy is discussed by citing the example of a two-element interferometer.

Studies in the Astronomy of the Roman Period.
Centaurus, 1997A dozen of papyri and other documents concerned with the longitudes and latitudes of the moon and mostly coming from Roman Egypt are analysed in great detail. The documents operate with zig-zag functions known to have originated in Babylonia. The author calls their arithmetical apparatus The Standard Scheme.

Radio Astronomy from a Lunar Environment Precursor Tests
Performing radio astronomy observations from the Earth’s surface is plagued with interference issues. The Earth and its surrounding atmosphere, particularly our ionosphere, are massive sources of natural interference. There are also human sources of interference. There have been several studies attempting to solve the issues surrounding radioEibhlin Laffan Downes, Bernard Foing

Solar and Lunar Eclipses in the Perspective of Shar’i And Astronomy
The moon is a satellite that has its orbit and goes around the sun at the same time as the Earth. So that the special position between the Sun, Earth, and Moon can cause an eclipse. To complete this research, the author uses qualitative methods, namely descriptive methods.Safira, Mia +2 more
