When choosing the type of orbit, spacecraft developers should consider its intended purpose, the data it acquires, and the services it offers, as well as the cost, coverage area, and feasibility of different orbits. The 5 main types of satellites based on their orbits are:low Earth orbit (...
Dynamics of Mars-Orbitting Dust: Effects of Light Pressure and Planetary Oblateness This paper deals with dynamics of impact ejecta from Phobos and Deimos initially on near-circular equatorial orbits around Mars. For particles emitted in a... AV Krivov,LL Sokolov,VV Dikarev - 《Celestial ...
the first is that the planet orbits a star, the second is that its gravity is large enough that it takes a spherical shape, and the third is that its gravity is large enough that it can have moons or stand on its own without the interception of other planets' orbits. ...
Vector One ships convey materials from planetary surfaces to orbit. Vector Two ships transport material between planets of a stellar system. And Vector Three ships range through the interstellar lanes. Vector Three ships, comprising a central cylinder and detachable cargo and cabin pods, are more ...

Definitions The word "spaceport" has a variety of connotations (in science fiction, for instance, it is even used to represent the port of entry and departure of future travelers at the Moon, planetary bodies, or at Lagrangian Points). At another level, it is sometimes used only to ...
The concepts of symmetry and its breakdown are investigated in two different terms according to whether the resulting asymmetry is universal or only obtained for a special configuration: we illustrate this by considering, in the first case, an example fr
In regards to the above models [5,34,35], a common assumption was that: “Estimates of the predictability of the planetary-scale motions of the atmosphere have been based on turbulence models in which the atmosphere is treated as an isotropic homogeneous two-dimensional turbulent fluid.” [35...
