Satellites of the planets and Lagrange points

Different planets "own" a different number of satellites. These planetary satellites are distributed in the Solar System is clearly uneven. The giant Jupiter has 15 of them, Saturn according to some data - more than 20, and as we approach the Sun the number satellites sharply decreases...

Is it possible to liquidate the night?

Is it possible to liquidate the night in general?.. It is known that the change of day and night is a direct result of the daily rotation Earth. Turning around its axis, our planet at every moment substitutes for the rays of the Sun only half of its surface... Due to this, some of the time people are forced to spend in the dark, spend enormous energy resources on the night lighting of rooms and streets...

In apogee or perigee?

In apogee or perigee?

The spacecraft starts from the an artificial Earth satellite, moving around the planet in an elliptical orbit. At what point is it more profitable to launch - when the satellite will be in apogee or perigee? It would seem that the answer is perfectly clear: of course, at apogee: after all, the farther from Earth, the weaker the gravity of gravity...

Space paradox

Space paradox

Consider now another space paradox, which runs counter to the usual notions of earthly mechanics. Our usual ideas show that the faster we move, the sooner we will overcome the given distance. When moving spacecraft in gravity fields of heavenly bodies bodies this statement is not always true. For example, it refuses to serve under one...

Faster than the fundamental speed!?

Faster than the fundamental speed!?

It is widely believed that the theory of relativity does not allow superluminal velocities. Is it so? Can speed exist in nature, faster than the fundamental speed of light? Indeed, from the point of view of the theory of relativity there is a certain fundamental speed c, which is the greatest possible for the propagation of any force interactions. What is its physical meaning?..

The moon is the natural diagnostician of the Earth!?

The results of studies conducted in recent decades by space agencies of various countries indicate a close interconnection of the planets solar system at the wave energy level. For example, data obtained by the European Space Agency (ESA) and the American NASA using the Ulysses spacecraft in 1990 showed that the Sun interacts with the Solar System more complicated than previously...
