Relative to fixed stars on a celestial sphere, the Moon takes 27 Earth days, 7 h, 43 min, and 12 s to complete one orbit (Lang 1992). Since the Earth-Moon system travels around the Sun at the same time, the Moon must travel further to return to the same phase. There are three ...

INFLUENCE OF ANTENNA PROPORTIONS ON PERFORMANCE The antenna area is defined by the choice of orbit, the transmission frequency, and the observation incidence domain. It should be noted that it is independent of resolution. The only possibility remaining for the radar designer is to use the ratio ...
The paper includes a correlation analysis of the orbit parameters, Earth rotation parameters and the geopotential coefficientC20, based on covariance matrices from weekly solutions. High correlation around 0.96 was found for LOD and the sine amplitude of the cross-track harmonic empirical acceleration, ...
In this case, the driving parameter is the electrostatic charge-to-mass ratio, a quantity that depends on the inverse square of characteristic length. This analysis presents a proposal for a small spacecraft that can demonstrate the Lorentz force in Earth orbit. A sample low charge-to-mass ...
We integrate the history of the lunar orbit with and without a sustained resonance, finding that the impact of a sustained resonance on the other orbital parameters of the Earth-Moon system would not have been large. 展开 关键词: Theoretical or Mathematical/ atmospheric movements atmospheric ...
How many miles of wire are in the Hubble Telescope? How many focal points are in the Newtonian telescope? How far above the Earth does the Hubble Telescope orbit? How many megapixels is the Hubble Space Telescope? Does the Hubble Space Telescope use adaptive optics?
The effects of the earth and ocean tides on the semi-diurnal lunar tide in the atmosphere have been ignored in nearly all studies of this air tide. Elementary arguments show that these boundary effects are not trivial. Using linear theor... A Hollingsworth - 《Journal of the Atmospheric Scien...

Correlation lengths of ultra-low-frequency (ULF) waves around Mars were computed for the first time, using data from MEX (electron density from 2004 to 2015) and MAVEN (electron density and magnetic field from 2014 to 2016). Analysis of the MEX data foun
