The paper is focused on the equations of the optimal guidance for planar Lunar ascent. We point out some computational and graphical aspects.

With the cancellation of the Apollo program after Apollo 17 returned from the Moon in 1972, the focus of NASA switched to other areas of the Solar System. Study of the Moon did continue through analysis of the returned samples and remotely sensed data sets (both orbital and surface), as well as through Earth-based telescopic studies. In the 1990s, new orbital data were obtained from several mis...

The Uranian moon Mab, located in Uranus’ outer ring system, has been observed to be undergoing significant changes in its orbit about Uranus. These changes are not attributable to gravity flattening effects or meanmotion resonances, which suffice to elucidate the motion of all other known Uranian moons. Mab was discovered in 2006 [1], along with the dusty μ-ring through analysis of images obtai...

The study of the thermal radio emission of the moon and planets began in 1946 with the detection of the thermal radiation of the moon at 1.25cm wavelength by Dicke and Beringer [1]. This was followed three years later by a comprehensive series of observations of the radiation from the moon at 1.25cm wavelength over three lunar cycles by Piddington and Minnett [2] showing that the thermal radiat...
