The Laboratory for Astrophysics (LfA) at the National Air and Space Museum (NASM) is proposing a new exhibit: an outdoor model of the Solar System on the National Mall, dedicated to the Spirit of Human Exploration. At one ten- billionth of the size of the actual Solar System, the model...
. Compared to the other bodies in this model, the asteroids are tiny. It would take twenty-five copies of all the asteroids to make a lump as big as the moon (seediameter comparison of Ceres, Moon, and Earth). The asteroids are also scattered over a huge circle, so obviously the ...
1. The idea of the possible exploitation of mineral resources from planets of the Solar System has ceased to be fanatical with man's extravehicular activity, especially on the surface of the Moon. The landing modules that have recently reached the surface of Mars will return invaluable information...
Recently discovered long-term oscillations of the solar background magnetic field associated with double dynamo waves generated in inner and outer layers of the Sun indicate that the solar activity is heading in the next three decades (2019–2055) to a M
PV system modelThis paper examines the level of model fidelity required to support design phases in the urban solar planning process.The two modelling features crucial to the fidelity of the photovoltaic(PV)yield prediction on urban surfaces are(1)a level of fidelity for modelling urban shading ...
We used a spectral radiative transfer model to compute the direct radiative effect (DRE) of natural plus anthropogenic aerosols in the solar near-infrared (IR), between 0.85?10 ?m, namely, their effect on the outgoing near-IR radiation at the top of atmosphere (TOA, ?FTOA), on the ...
Multi-scale macroalgae growth models are required for the efficient design of sustainable, economically viable, and environmentally safe farms. Here, we develop a multi-scale model for Ulva sp. macroalgae growth and nitrogen sequestration in an intensive
Large-scale variations in the obliquity of the planet Mars are produced by a coupling between the motion of its orbit plane due to the gravitational perturbations of the other planets and the precession of its spin axis which results from the solar torque exerted on the equatorial bulge of the...
Charged energetic particles diffusion in solar wind with flux‐tube‐structures In this paper we construct a model turbulence of the solar wind by including the flux‐tube‐like structures. We start by cutting the solar wind ... G Qin,G Li - American Institute of Physics 被引量: 4发表: 20...
the mantle density of Venus approaches the Preliminary Reference Earth Model (PREM); the internal structure, together with the similar basaltic crusts as boundary layers, suggests similar thermal structures and convective dynamics of the mantles24. Thus, we assumed similar tectonic dynamics in their ...
