100 year spaceship

Humanity seems to have stayed in their home Solar system

In Houston there was a scientific conference on the most ambitious project of the century.

“Transition to transformation”

Humanity seems to have stayed in their home Solar system. Of his burning desire to go to other stars, scientists said at a scientific conference, held in October in Houston (Texas, USA). Experts discussed the most grandiose project of the century – “Centennial spaceship” (“100-Year Starship”, or 100YSS ).

– Despite all the technological advances of humans, in the field of space exploration we’re on the level of cave people, – assured the leader of 100YSS Mae Jamison. All we did was hang a station in earth orbit, where just sometimes come to live people. And also sent a robot to Mars, which only publishes Pictures in Instagram and writes in Twitter. The main task of space exploration in the long term should be the creation of colonies, which can live people. Continue reading

Solar system

It would seem that in the Universe can be arranged easier and more reliable than our Solar system . A crucial role is played by force of gravity; the motion of each planet around the Sun is subject to clear and unambiguous laws – the laws of Kepler; this movement is almost the same, common to all planets, except Pluto’s, the plane.

In reality things are not so simple. The fact is that on each of the planets of the Solar system is not only the power of solar gravity, but the force of attraction of the other planets. This pull causes disturbances in the movement of each of the planets of the Solar system. Several planet deviates from its normal path prescribed by the laws of Kepler, however, every time returning to it. When you consider that the mutual position of the planets of the Solar system changes all the time, it becomes obvious that the overall picture of their movement very difficult.

And so the question arises. If the perturbations of the planetary movements of the Solar system lead to irreparable disaster? Where is the guarantee that whenever getting off the rails invisible space, the planet will return to a “native” orbit? But if the deviation is too large? And if all this “inside buildup”, a kind of vibration, to cause Ravalomanana system? Continue reading

The history cosmonautics

April 12 is known to all of us, as the Day of cosmonautics . On this day we celebrate the memorable date – the first successful manned flight into space . In 1961 on this day the Soviet cosmonaut Yuri Gagarin on Board the spaceship “Vostok-1” was launched from the cosmodrome “Baikonur” and made an orbital flight . lasted 108 minutes . This was a major breakthrough in the history of space exploration. But the space also had its history . and humanity had a long way to go to finally “reach for the stars”. This will be discussed in this article.

The idea of space flight appeared almost immediately after the emergence of the heliocentric system of the world and the understanding that other Earth-like planets can somehow be reached. The first published description of human presence on the moon was a fantastic story of Kepler’s “Somnium”(1634) .

First the theoretical foundations of cosmonautics was laid by Isaac Newton in his work ” Mathematical principles of natural philosophy “( 1687 year). Later important contribution to the theory of calculation of the motion of bodies in outer space were made by Euler and Lagrange. Continue reading
